Description

The The present invention relates to a sun visor system, and more particularly a sun visor system with a shielding for covering or covering a vehicle window to prevent sunlight.

is a vehicle parked in the burning sun, and enters sunlight in a passenger compartment of the vehicle, so the temperature rises in the passenger compartment. Return a passenger and sit in the passenger compartment of the vehicle, the passenger is exposed to heat and feels uncomfortable. Will in such a situation an air conditioning system or an air conditioner is switched on, it is at the beginning of the operation the air conditioning hot Air blown out of the air conditioning system in the direction of the passenger, that yourself the passenger feels uncomfortable. In such a case, that is for lowering the temperature of the passenger compartment to a desired, comfortable value needed Time also comparatively long. Must the temperature beyond that must be lowered rapidly, so must one increased Amount of cooling air promoted by the air conditioner become. this leads to to an increased Power consumption.

So far became common a separate sun visor used. The sun visor is placed on the passenger compartment side of a windscreen to to prevent sunlight from entering the passenger compartment to shadow. The sun visor is simply along the window or the disc arranged without them with the disc or the disc to connect, or she is using, for example, with suction discs connected to the disc. For However, the separately available sun visor storage space is needed, if the sun visor is not in use. The separate or separated present sun visor weakens the appearance of the interior of the passenger compartment or has a negative effect on this.

With the goal of meeting the above disadvantages is revealed by the unaudited Japanese Patent Publication No. 2003-182358 a sun visor system. In this sun visor system is a shielding track at a lower end of a side window (door window) of a vehicle and is wound from the lower end of the side window Direction extended to an upper end of the side window. she can not serve as a sun visor in such a case. To counter the entering into the passenger compartment of the vehicle sunlight must shadow the Abschirmbahn substantially to the upper end of the side window extend. Here is a lower part of the side window of the Covering covered, and a passenger can not therefore by the Side window to the outside see.

The unaudited Japanese Patent Publication No. 2003-52763 suggests a sun visor system which is installed in a vehicle. at this sun visor system, which covers the sunlight by covering a screen of a vehicle or shaded, is a Shielding path by cranking a winch device retracted or extended. The winch device extends linearly near an upper edge a passenger compartment side of a window or a pane. Even if an airbag in a dashboard in front of a front vehicle seat is arranged, the winching device does not hinder the airbag, because the winching device is arranged at the upper edge of the disc. It is therefore possible to provide the sun visor system on the windscreen.

In the unaudited Japanese Patent Publication No. 2003-52763 is a base end of the rectangular shielding sheet attached to the winch device, and a tubular support is along a free end of the Abschirmbahn connected thereto. left and right push rods are in right and left ends of the bracket introduced in such a way that the Push rods are displaceable in the axial direction of the bracket. A runner is with an outer end connected to each push rod.

Along of front pillars of the vehicle left and right guide rails are arranged. The runners are each along the guide rails move bar. Each guide rail takes a flexible baffle with a lower, attached to the runner End up. The flexible guide element is provided by a drive device driven to move along the guide rails.

In in the unaudited Japanese Patent Publication No. 2003-52763 disclosed sun visor system become the runners, the push rods and the bracket along the guide rails moved to extend or retract the shielding when the drive device is driven to each flexible guide element along the corresponding guide rail to move.

The windscreen of the vehicle is generally trapezoidal in shape, with the width increasing toward its lower end. In the above-mentioned sun visor system, therefore, a space between the guide rails increases toward the lower ends. In the sun visor system, the push rods are thus displaced in accordance with the space between the guide rails, that the entire length of the holder and the push rods adapted or a is provided.

The in the unaudited Japanese Patent Publication No. 2003-52763 disclosed conventional Sun visor system is operated such that when always the sun visor system is needed, the shielding is extended to cover the disc and thereby against to shade the sunlight. Unlike the sun visor, which runs along the disc, without being connected to the disc, or with the disc, for example connected by means of suction discs, requires the above sun visor system the prior art no large storage space. The above Sunblind system of the prior art is also such in the vehicle body integrated that it the appearance of the interior of the passenger compartment is not adversely affected or diminishes.

The Windscreen is however trapezoidal designed with its width increases towards its lower end. When the above sun visor system is fully extended is, are usually triangular spaces, which are not covered by the shielding, to the left and left side of the disc, and the sunlight passes through the uncovered rooms or Areas in the passenger compartment, causing an increase in temperature in the passenger compartment.

The Windscreen of the vehicle is also curved such that a center the windscreen towards a front end of the vehicle, compared with the left and right sides of the windscreen, convex is. In addition, a rear window of the vehicle is curved such that a center the rear window towards a front end of the vehicle, compared with the left and right sides of the rear window, convex is. If a linear role of the winch device around which the Shielding path is wound, attached to the roof side of the vehicle is, so has the Role in the event that they installed on the windscreen, from the windscreen in the direction of It must be spaced from the rear end of the vehicle, or it must be from the rear window be spaced in the direction of the front end of the vehicle, if it is attached to the rear window. However, a disturbance or interaction for example, with a sunroof to prevent, and to one to create wide space in the passenger compartment, it is desirable that Roll as close as possible to place on the corresponding disc.

In the above-mentioned, conventional sun visor system the unaudited Japanese Patent Publication No. 2003-52763, the shielding sheet by means of the drive device extended or retracted. The shielding can therefore not retracted or moved back when the drive device fails or malfunctions.

It is therefore an object of the present invention, an improved sun visor system to provide which at least one of the above-mentioned disadvantages encountered.

to solution the task of the invention becomes a sun visor system for a vehicle proposed. The sun visor system has a shielding path and a coasting shading device. The shielding serves to cover a window or a window of the vehicle. The coasting shading device is in a normal direction and rotatable in an opposite direction to the Abschirmbahn roll out and roll up. The roll-out shade device is disposed along an edge of the disc. The roll-out shading device has a central axis corresponding to a shape of the edge of the window or disk is curved, and a rotatable Rod, which receives the central axis hereby and with a base end the shielding is connected. The rotatable axis is corresponding the curved shape the central axis curved, and it is rotatable about the central axis. The rotatable rod has a plurality of cylindrical central rods and a Plurality of connections. Each connection provides the connection between two corresponding central rods of the plurality of central rods. Each of the opposite ends of each central rod has at least one engaging projection, which from the End of the central rod in a direction parallel to an axial Direction of the central rod protrudes. Each of the opposite Ends of each connection has at least one engagement recess, each with a corresponding engagement projection of at least one in an adjacent one of the ends of a corresponding central one Rod of the plurality of central rods is engaged.

However, the present invention is not limited thereto. For example, instead of each spiral cable 34 a flexible cable element, which on the corresponding sliding piece 35 secured distal end has to be used. In such a case, a rack is designed in the flexible cable element, and the output gear 11a is used as a pin to form a rack and pinion structure which drives the flexible cable element. Alternatively, each line may be wound up by the motor to form the corresponding sliding piece 35 to pull to the fully extended position and vice versa.

Instead of the spiral cable 34 Further ball screws can be used. The torque of the output wheel 11a will be in such a. Transfer case on each screw shank, which serves as a transmission element. With this Vorrich tion of the screw shaft by the rotation of the output wheel 11a turned, and the nut of a ball screw, which as a sliding piece 35 serves, is along the corresponding guide rail 31a emotional.

Next, the coasting-shading mechanism 20 of the present embodiment described in detail. As in the 4 to 7 is shown, the Ausroll-shading mechanism 20 According to the present embodiment, the coasting shading device 22 , Roll-out shade holder 26 , the shielding 21 , a leadership 27 and the push rods 28 on. The roll-out shade holder 26 are at opposite ends of the roll-out shading device 22 arranged and carry the Ausroll-shading device 22 , A base end of the shielding membrane 21 is on the roll-out shading device 22 secured or secured. The management 27 and the push rods 28 are along a free end of the Abschirmbahn 21 connected with each other. The roll-out shade device 22 is designed in particular in a cylindrical shape and along a reinforcement 4 curved, which in a connection W1 between the disc W and the roof 2 is arranged. The management 27 and the push rods 28 correspond to a shaft or a shaft of the present invention.

Looking at the disc W from the side of the passenger compartment, the disc W is curved so that they. is convex in a widthwise center of the disk W toward a front end of the vehicle as compared with the left and right sides of the disk W. The connection W1 between the disc W and the roof 2 is curved, as in 4 is shown. Further, the curved reinforcement 4 as in 4 and 7 shown connected to the connection W1 by welding, for example, wherein the compound W1 forms the upper edge of the disc W. As discussed above, in the coasting shadowing mechanism of the present invention 20 the roll-out shade device 22 around which the shielding 21 wound or wound behind the reinforcement 4 arranged and follows the curved or curved shape of the reinforcement 4 , The roll-out shade device 22 Therefore, it can be arranged adjacent to the disk W. Since the roll-out shading device 22 is curved, a space is further provided, which at least partially with the Ausroll-shading device 22 is or is limited. The motor 11 is advantageously arranged in this space, with an interference or disturbance, for example, a sunroof system, is avoided.

As in 7 In this way, the coasting shading device can be shown 22 and the engine 11 the drive device 10 successively in the front-to-rear direction of the vehicle in the space between a ceiling or sky fairing (an interior trim or decoration element) 2a and the roof 2 to be ordered. In other words, it does not require the coasting shading device 22 and the engine 11 one after the other in the vertical direction above the head of a driver. Above the head of the driver, therefore, a suitable space can be created. The roll-out shade device 22 As discussed above, is curved along the edge of the disc W such that the device surrounds the coasting shading device 22 and the drive device 10 is designed to be compact in the front-to-rear direction and also in the vertical direction of the vehicle.

As in 4 is also shown, a disc-shaped mirror holding member or a mirror holder 5a on the engine mounting element 12 attached and protruding forward, and a room mirror 5 is with the mirror holder 5a connected to form a holder.

Two holders 36 for the track delimiting element are under the reinforcement 4 each with the cable ladder 32a . 32b connected. Ends of a track-limiting element 37 are each by the holder 36 worn for the track delimiting element. In the present embodiment, the web limiting member 37 is designed as a V-shaped flat disc projecting toward the front end of the vehicle, as in FIG 4 is shown. A position of each of the upper ends of the guide rails 31a . 31b is substantially coincident with a position of the adjacent front edges of the sheet delimiting element 37 match.

The shielding 21 is between the track delimiting element 37 and the reinforcement 4 arranged. This structure or device advantageously limits the movement of the shielding web 21 in a direction away from the surface of the disk W in the fully extended state of the Abschirmbahn 21 , As discussed above, the track-limiting element keeps 37 the shielding 21 in the position near the upper ends of the guide grooves 31a . 31b if the shielding 21 from the coasting shading device 22 is pulled in the direction of the disc W, ie in the position near the upper edge of the disc W.

The shielding 21 So is the rolling-shading device 22 pulled forward and then on the track-limiting element 37 so deflected or -leited that the shielding 21 in the oblique direction along the inner surface of the disc W is pulled down. As it is the track-limiting element 37 there, the shielding can 21 cover the inner surface of the disc W near the inner surface of the disc W. The shielding 21 thus can effectively limit a rise in temperature in the passenger compartment caused by sunlight.

The track-limiting element 37 In the present embodiment, as discussed above, it is configured as a V-shaped disk. The track-limiting element 37 may alternatively be configured as a curved plate which extends along the connecting line between the disc W and the roof 2 is curved to substantially coincide with the connecting line. The track-limiting element 37 Furthermore, it does not necessarily have to be a disc or a plate. The track-limiting element may, for example, be a roller / rollers which is rotatably supported by a corresponding rotatable shaft. Will the shielding 21 extended or retracted in such a case, the roller or roller allows a gentle movement of the Abschirmbahn 21 ,

The roll-out shade device 22 which, as in the 8th to 10 is curved, has a central axis 22a , a spiral spring 22b , a cylindrical pen holder 22c and a cylindrical, rotatable rod 22d on. The central axis 22a is symmetrically curved with respect to the center of the width of the vehicle body. One end of the spiral spring 22b is at one end of the central axis 22a connected or secured to this. The other end of the coil spring 22b is rotatable at the other end of the central axis 22a arranged and on the penholder 22c secured or secured. The rotatable rod 22 covers the central axis 22a and the coil spring 22b from.

The base end of the screening track 21 is with the rotatable rod 22d connected. The rotatable rod 22d has coupling rods 23 , Links 24 and center bars 25 on which to make the rotatable rod 22d connected to each other. The coupling rods 23 , the connections 24 and the center poles 25 For example, are made of synthetic resin and designed as a solid body, which do not have the flexibility and elasticity, as it has rubber, for example. The ends of the central axis 22a are each with the roll-out shade holders 26 connected or secured to this. The spiral spring 22 is further rotated to in a winding direction of the Abschirmbahn 21 to exert a torque.

The central axis 22a is merely for maintaining the state of curvature in attaching the ends of the central axis 22a each on the roll-out shade holders 26 required. The central axis 22a may therefore be a permanently curved or bent tubular resin element. The central axis 22a may alternatively be made of a flexible material and curved when the central axis 22a with the roll-out shade holders 26 is connected.

The coupling rods 23 are each at the ends of the central axis 22a arranged. Regarding 10 is an end face (in 10 a left end surface) of one of the coupling rods 23 essentially annular. A flat surface portion, which as one with the pen 22c is engaged engaging portion is in an interior of the coupling rod 23 designed. The coupling rod 23 and the penholder 22b are inserted one inside the other to rotate integrally. In the other end surface of the coupling rod 23 At 180 ° intervals are two engagement projections 23a designed such that each engagement projection 23a protrudes in the axial direction and has a predetermined annular width.

Like the engagement projections 23a the coupling rods 23 stand two engagement sections 25a from each end of the center bar 25 out. The engaging sections 25a which are in one end of the center bar 25 are provided, however, are at 90 ° to the other end of the same center rod 25 provided engagement projections 25a added.

Every connection 24 connects between the corresponding coupling rod 23 and the corresponding center bar 25a or connects between the center poles 25 , In each end of the connection 24 are therefore two engagement sections 24a , which are in the engaging sections 23a or the engaging sections 25a intervene, designed. Like the intervention sections 25a the center bars 25 are also the engaging portions 24a which in one end of the connection 24 are provided 90 degrees from the engagement recesses 24a offset, which in the other end of the same connection 24 are provided. The engagement projections 23a one of each coupling rod 23a and the engagement projections 25a every center pole 25 are loose in the engagement recesses 24a the corresponding connection 24 inserted to the coupling rods 23 , the center poles 25 and the connections 24 to connect with each other.

In this way, the rotatable rod 22d , which are the coupling rods 23 , the connections 24 and the center poles 25 has, axially connected, while the central axis 22a through the rotatable rod 22d is introduced. Are these components in a subunit for designing the roll-out shading device 22 designed, so is a free space (game) between each adjacent two of the coupling rods 23 , the compounds 24 and the center bars 25 created. Due to the present game, every coupling rod can 23 or center bar 25 , which with the appropriate connection 24 is connected, based on the connection 24 bent by 90 °, which or what serves as a joint.

In the present embodiment, the connection between the engaging projections 23a . 25a and the engagement recesses 24a by simply engaging the engagement projections 23a . 25a with or in the engagement recesses 24a achieved or achieved. Alternatively, a hinge pin or the like may be used to rotatably connect them so as to allow smooth pivotal movement of the hinged members.

A circumferential width of each engagement projection 23a . 25a also substantially corresponds to the circumferential width of the corresponding or associated engagement recess 24a , Will the rotatable rod 22a around the central axis 22 rotated, so transmits or directs the rotatable rod 22d the torque without a significant positional deviation of a coupling rod 23 , a connection 24 or a center pole 25 to cause. The coupling rods 23 , the connections 24 and the center poles 25 which are connected to each other in the axial direction can thus be integrally rotated while the coupling rods 23 , the connections 24 and the center poles 25 conforming to the curved shape of the central axis 22 are curved.

The roll-out shade device 22 is designed in the manner described above in such a way that the Ausroll-shading device 22 . which is designed as a sub-device, along the reinforcement can be curved and on the Ausroll-Verschattungshaltern 26 can be attached or secured at their ends. The central axis 22a is here on the roll-out shade holders 26 attached, and the rotatable rod 22d which are around the central axis 22a is arranged around, can be rotated, with the rotatable rod 22d in conformity or as the curved shape of the central axis 22a is curved. That is, even if the rotatable rod 22d around the central axis 22a is rotated, which as the axis of rotation of the rotatable rod 22d serves, the curved shape of the central axis 22a is maintained, wherein the rolling-shading device 22 maintains the curved shape, which with the curved shape of the reinforcement 4 matches or corresponds to this.

Next, for comparative purposes, an exemplary comparative case will be described. In the exemplary comparative case, the coasting shading device 22 made of an elastic tube such as a vinyl tube, wherein ends of the elastic tube are rotatably supported by holders. Due to the elasticity of the elastic tube, the elastic tube may in such a case along the reinforcement 4 to be curved. However, due to the prevailing twist of the vinyl tube, the left and right ends of the shielding sheet may disadvantageously be uneven about the coasting shading device 22 be wound or wound. Will the design of the roll-shade device 22 a permanently curved rigid resin tube, each end of the plastic tube will orbit disadvantageously along a relatively large circular path when the resin tube is rotated.

In order to limit the occurrence of such a deviation, in the coasting shading device 22 rigid components (for example, the center rods 25 ) be used. When the rigid components are used in the coasting shading device, a twist is generated in the coasting shading device such that the shielding web 21 can not be soft or gently extended or retracted. In the present invention, the rotatable portion is the coasting shading device 22 therefore from the middle poles 25 and the coupling rods 23 built, which by means of the compounds 24 connected to each other.

As discussed above, this is one end of the coil spring 22 further on the central axis 22a attached, and the other end of the coil spring 22b is on the rotatable rod 22d through the pen 22c connected. Will the rotatable rod 22d turned to the front to the shielding 21 extend, so the rotational force on the Spi ralfeder 22b in a direction of retraction on the shielding sheet 21 applied. At the time of extension of the shielding 21 Therefore, a tension on the Abschirmbahn 21 applied so that the shielding 21 soft or gentle at the time of retraction of the Abschirmbahn 21 by means of the spring force of the coiled or twisted spiral spring 22b can be withdrawn.

The shielding 21 In the present embodiment, a sheet material which has a predetermined light transmittance and is in the rolling / rolling-in direction of the screening sheet 21 does not substantially stretch while in the direction of the width (a direction which is perpendicular to the rolling / rolling-in direction of the shielding web 21 stands) is stretchable. In a natural state has the shielding 21 Further, a shape that approximates a rectangular shape. In the stretchable sheet material which is stretchable in the widthwise direction, for example, stretchable threads are used as threads extending in the widthwise direction. Even if the filaments have little stretchability, the web can be made to be stretchable in the direction of the width by suitable weaving. A web material, which is stretchable in the direction of the width as well as in the rolling / rolling-in direction, can furthermore be used for the design of the screening web 21 be used.

In the present embodiment, the shielding sheet is 21 fully stretchable in the direction of the width. Alternatively, each left and right end of the Abschirmbahn 21 be formed of a sheet material which is stretchable in the direction of the width, wherein the center of the Abschirmbahn 21 , which with the leadership 27 can be configured from a web material which has only low extensibility or no stretchability in the direction of the width. These webs can be sewn together to form the Abschirmbahn or sewn together.

The free end of the shielding 21 is with the hollow leadership 27 which is bent at its center to a V-shape and has at its left and right ends linear or straight sections ( 1 ). A variety of hook and loop fasteners 6a , each of which has a predetermined length, is on the Abschirmbahn 21 attached. A variety of hook and loop fasteners 6b , each of which has a predetermined length, is on the guide line 27 attached. The shielding 21 and the management 27 are by connection between the hook and loop fittings 6a , which are at the shielding 21 are attached, and the hook and loop fasteners 6b , which at the Füh insurance line 27 are attached, detachably connected ( 14A and 14B ).

As in 6 shown are the push rods 28 each slidable in the left and right ends of the guide line 27 added. Alternatively to the in 6 shown device can be in the leadership 27 be provided two coil springs. In such a case, an inner end of each coil spring is at an inside of the guide line 27 fixed, and an outer end of the coil spring is at the inserted or inserted end of the corresponding push rod 28 attached, which in the leadership 27 introduced or inserted. In this way, every push rod becomes 28 forced or pressed laterally outwards by means of the corresponding spiral spring.

The management 27 Further, it may be curved with a predetermined curvature to correspond to the curved shape of the disk W. In such a case, the push rods can 28 who are in the leadership 27 are inserted, be shaped so that they correspond to this curvature to a sliding or sliding movement of the push rods 28 relative to the management 27 to enable.

As in 5 is shown is a hook and loop attachment 6b which has a predetermined length, at the outer end of each push rod 28 attached. There is also a hook and loop fastening 6a , which has a predetermined length, on each left and right lateral side of the free end of the shielding web 21 attached. Every push rod 28 and the shielding 21 are also removable by a connection between the hook and loop attachment 6a , which are at the shielding 21 is attached, and the hook and loop fastening 6b , which at the push rod 28 is attached, interconnected.

As described above, the space between the left guide rail takes 31a and the right guide rail 31b towards the lower end of the disc W too. Be the shifting pieces 35 moved down, so are the push rods 28 who are in the leadership 27 are increasingly plugged in, therefore increasingly from the management 27 pulled out. Be the guide rods 28 from the management 27 pulled out, then the shielding 21 through the push rods 28 pulled outwards so that the shielding 21 stretches in the direction of the width.

The system S of the present embodiment is constructed as described above. When the Abschimbahn 21 is fully extended or rolled, the shielding stretches 21 in accordance with the shape of the disk W in the width direction. The shielding 21 can therefore cover or cover substantially the entire surface of the disc W substantially.

The 11A shows the state in which the shielding 21 completely wound up (the fully retracted or retracted position). 11B shows the state in which the shielding 21 is fully extended or rolled (the full shadow position or shading position or simply called shadow position). As in 11B 2, in the system S of the present embodiment, substantially the whole area of the disk W in the full shade position can be covered to shade against the sun light. This means that no triangular space (unshaded portion) remains on the left and right sides of the disk. It is therefore possible to limit an increase in the temperature of the passenger compartment, which would be caused by the transmission of sunlight through the triangular space in the passenger compartment faster.

With reference to 12 In the following, the electrical construction of the system S will be described. The system S has a controller 40 on which a drive signal for the motor 11 the drive device 10 which outputs a driving force for unrolling or curling the Abschirmbahn 21 generated. The control 40 has a microcomputer. The control 40 receives a control signal of an operation switch 41 , a measuring signal of a temperature sensor 42 , a measurement signal of an optical sensor 43 , a measurement signal of a position sensor 44 and a measurement signal of a gear position sensor 45 , The operating switch 41 is operated by the passenger. The temperature sensor 42 feels the temperature of the passenger compartment. The optical sensor 43 detects a lighting and a direction of incidence (angle) of the sunlight, which enters the passenger compartment. The position sensor 44 detects the position of the Abschirmbahn 21 , The gear position sensor 45 detects a gear position of the vehicle. The control 40 gives a drive signal to the motor 11 off to the engine 11 to rotate in the normal direction or the opposite direction.

The operating switch 41 has a plurality of switching elements for curling or retracting the Abschirmbahn 21 and for extending or unrolling the Abschirmbahn 21 on. If the passenger wishes to extend or retract the shielding, then so. the passenger selects and operates the corresponding switching element of the operating switch 41 such that a corresponding actuation signal from the actuation switch 41 to the controller 40 is delivered. Receives the control 40 the control signal, so gives the controller 40 a corresponding drive signal to the motor 11 based on the actuation signal down to the motor 11 to turn accordingly in the normal direction or the opposite direction.

The temperature sensor 42 and the optical sensor 43 are arranged in predetermined means (ie, on the inner surface of the disc W or an upper portion of a dashboard) in the passenger compartment. The temperature sensor 42 detects or measures the temperature of the passenger compartment and gives the measurement signal, which corresponds to the measured temperature, to the controller 40 from. The optical sensor 43 Measures the illumination or illumination and the angle of incidence of the sunlight entering the passenger compartment.

The optical sensor 43 For example, the illumination of the sunlight entering the passenger compartment can be measured as described above. The optical sensor 43 may further detect whether the sunlight enters the passenger compartment within a predetermined range for the angle of incidence (direction). The optical sensor 43 has single or multi-directional sensor elements and detects that the sunlight enters within a predetermined angular range in the passenger compartment, in which the sunlight reaches the height of the eyes of the driver or a passenger sitting on a front passenger seat.

A slit device may be in front of the sensor element of the optical sensor 43 be provided to achieve the bundling such that only the predetermined incident sunlight, which enters the passenger compartment at a predetermined angular range, a surface of the sensor element of the optical sensor 43 reached. The device of the optical sensor 43 is not limited to the inner surface of the disc W or the upper portion of the instrument panel, wherein the optical sensor 43 for example, may be provided on the holder of the mirror.

The control 40 monitors the measurement signals described above. In a parked state of the vehicle when the controller 40 based on the measurement signal of the gear position sensor 45 determines that the vehicle is parked when the controller 40 based on the measurement signal from the temperature sensor 42 determines that the temperature of the passenger compartment is equal to or greater than the preset temperature, or if the control 40 based on the measurement signal from the optical sensor 43 determines that the illumination of the sunlight entering the passenger compartment is equal to or greater than the predetermined value gives the controller 40 automatically the drive signal to the motor 11 off to the shielding 21 To drive or roll out and thereby cover the disc W to shade the sunlight. The control 40 notes, for example, that the vehicle is in the parked state when the transmission is in the park position.

The temperature of the passenger compartment is in particular equal to or greater than the predetermined temperature when the vehicle in not extended or unrolled Abschirmbahn 21 parked. Detects or determines the controller 40 However, that strong sunlight enters the passenger compartment, so the shielding 21 automatically extended or extended to limit an increase in the temperature of the passenger compartment. As described above, the automatic unrolling or extending of the screening web 21 the temperature rise in the passenger compartment advantageously limited. It is therefore not necessary to increase an air flow through an air conditioning system of the vehicle to quickly lower the temperature of the passenger compartment when the driver returns to the vehicle, whereby the waste of a considerable amount of energy can be prevented or limited.

The position sensor 44 detects, as explained above, the position of the Abschirmbahn 21 , The position sensor 44 For example, with reference to 13 a plurality of limit switches located at a plurality of positions, such as the fully retracted position (the position A in FIG 13 ) and the fully extended position (the position C in FIG 13 ) along the guide rails 31a . 31b are provided. Touches the sliding piece 35 one of the limit switches, a signal is emitted from this limit switch. The control 40 therefore, the position of the sliding piece 35 determine or record based on this signal.

Alternatively, the number of revolutions of the coasting shading device 22 are detected to the position of the Abschirmbahn 21 to detect, wherein a measuring signal, which is the number of rotations of the rolling-shading device 22 indicates to the controller 40 can be transferred.

Is the drive signal automatically or manually to the motor 11 delivered to the shielding 21 to move, so receives the control 40 the measurement signal from the position sensor 44 to the position of the shielding 21 capture. Based on the measurement signal from the position sensor 44 determines the control 40 whether the shielding 21 in the fully extended position or in the fully retracted position be finds and interrupts the transmission of the drive signal at this position. If the transmission of the drive signal is interrupted, then the shielding 21 in the fully retracted position, the fully extended position, or an intermediate position therebetween, by means of a self-retaining mechanism (eg, a clutch) installed in the engine 11 is intended to be held.

The system S shown above may be used as a sun visor. In the system S, the one or more intermediate stored positions may be provided between the fully retracted position and the fully extended position. The system S may be configured such that the shielding 21 when driving the vehicle automatically extends or extends to the corresponding intermediate position. 13 schematically shows the system S. A position A of 13 "shows the fully retracted or rolled-up position of the Abschirmbahn 21 as discussed above. The position C off 13 indicates the fully extended or unrolled position of the Abschirmbahn 21 as discussed above. The position B of the 13 shows the intermediate position of the shielding 21 ,

The control 40 When driving the vehicle automatically gives the drive signal to the engine 11 off to the shielding 21 to extend to the intermediate position when the controller 40 based on the corresponding signal from the gear position sensor 44 determines that the vehicle is in driving when the controller 40 based on the measurement signal from the optical sensor 43 determines that the illumination of the incident sunlight is equal to or greater than a predetermined value and the direction of incidence of the incident sunlight is within a vorbe certain angle range. The control 40 stops transmission of the drive signal to the motor 11 if the shielding 21 extended to the intermediate position or rolled out.

Determines the controller 40 in that the illumination of the incident sunlight is less than the predetermined value, and if the direction of incidence of the incident sunlight is outside the predetermined angular range, the controller transmits 40 the drive signal for turning the motor 11 in the opposite direction to the engine 11 to the shielding 21 automatically retract or unroll.

To perform this operation, the operation switch 41 a corresponding switching element which is served to the Abschirmbahn 21 to extend to the intermediate position. The control 40 detects the driving state of the vehicle, for example, when the gear is engaged in a driving position.

The system S can be changed as follows. The control 40 For example, in a fully extended or unrolled position of the Abschirmbahn 21 when the vehicle is parked automatically the drive signal of the engine 11 in the opposite direction to the shielding 21 to move to the fully retracted or rolled-up position when the gear is placed in the drive position. The system can also be changed as follows. The shielding 21 For example, even when the gear is in the drive position, it can be moved to the fully retracted position when the operation switch 41 manually operated by the passenger.

Vehicles have on the side of the driver's seat and on the side of the passenger seat thin, disc-like sun visors. At the front of the vehicle facing side of each sun visor, a hinge is provided. The passenger swings the sun visor around the hinge toward the front to shade the sunlight. The sun visor moves while pivoting the sun visor over the head of the driver. This may interfere with the driver's control of the vehicle. However, the above-described system S may serve as a sun visor and not move over the head of the driver and thereby disturb the driver in controlling the vehicle. The system S also moves the shielding 21 automatically off. The passenger or driver must therefore switch 41 for shading the sunlight through the Abschirmbahn 21 do not press.

As described above, in the system S, the drive signal from the controller 40 to the engine 11 based on the signal of the operating switch 41 or the measurement signal transmitted by the sensor (s). The engine unit 13 of the motor 11 is then rotated based on the drive signal. The torque of the motor unit 13 is on the spiral cable 34 through the exit wheel 11a transferred to the spiral cable 34 drive. Be the spiral cable 34 driven, so the shifting pieces 35 moved down or up to the shielding path 21 drive out or roll up.

The shielding 21 gets off the engine 11 wound. If the drive signal is not appropriate to the motor 11 transmit or there is a problem with the source of the drive power, then the shifting pieces 35 , which on the spiral cables 34 secured or secured in the guide rails 31a . 31b stopped. The shielding 21 can not be wound from the fully extended state to the fully retracted state in such a case.

However, the system S is designed to wind the shielding sheet 21 to allow in the fully retracted or rolled up state.

14A shows an exemplary state in which the Abschirmbahn 21 in the fully extended position. The passenger can make the connection between the hook and loop fasteners 6a and the hook and loop fasteners 6b manually lift to the shielding 21 from the management 27 and the push rods 28 to solve.

Is the shielding 21 from the management 27 and the push rods 28 solved, so is at the shielding 21 pulled with a force due to the coil spring 22b in the reeling direction, and it is wound up. Even if the above problem occurs, a clear view can be obtained through the disk W in this way.

If the above-mentioned problem occurs, system S may have the driving device 10 also be operated manually to the drive device 10 to operate such that the shielding 21 is wound in the retracted state.

As in 15 is shown, the mechanism points 14 for reducing the speed of the engine 11 represents a transmission device 15 for reducing the speed, a coupling device 16 (a connecting device), a switching device 17 and a spur gear 18 on. The transmission device 15 to reduce the speed reduces the rotational speed of the motor unit 13 , The coupling device 16 transmits the rotational speed of the transmission device 15 to reduce the speed to the output wheel 11a , The switching device 17 is compared with the coupling device 16 closer to the exit wheel 11a arranged. The spur gear 18 stands with the switching device 17 engaged.

The coupling device 16 is designed as an electromagnetic clutch and has rotatable shafts 11c . 11b on. The rotatable shaft 11c is with the transmission device 15 connected to reduce the speed, and the rotatable shaft 11b is with the output gear 11a connected. Will the engine 11 operated without the above problem without interference, so conducts the coupling device 16 the normal rotation or the rotation in the opposite direction of the rotatable shaft 11c by means of the rotatable shaft 11b on the output wheel 11a above. Will the engine 11 However, no drive power supplied or detects the controller 40 an irregularity, so is the connection between the rotatable shaft 11c and the rotatable shaft 11b canceled. The transition of the rotational force of the Getriebevor direction 15 to reduce the speed to the output wheel 11a is interrupted in this way, and the transmission of the torque from the output wheel 11a on the transmission device 15 to reduce the speed is also interrupted.

The switching device 17 has an engagement portion on the drive side 17a and on the driven side an engaging portion 17b on. The engaging section 17a the drive side is on the side of the coupling device 16 arranged, and the engaging portion 17b the driven side is a predetermined distance from the engaging portion 17a the drive side in the axial direction of the rotatable shaft 11b spaced. The engaging section 17a the drive side is on the rotatable shaft 11b attached and rotates in one piece with the rotatable shaft 11b , The engaging section 17b the driven side is loose on the rotatable shaft 11b arranged or inserted.

The engaging section 17a the drive side has a base 17AA and an engaging projection 17ab on. During normal operation of the engine 11 becomes the engaging projection 17ab by means of the base 17AA generated electromagnetic force, as in 15 shown the base 17AA arranged adjacent. When an error occurs, the base stops 17AA however, to generate electromagnetic force. On the engagement projection 17ab is therefore acted upon and it is by a (not shown) pressure device in a direction away from the base 17AA emotional.

The engaging section 17b the driven side has a spur gear 17ba and an engagement groove portion 17bb on. The engagement groove portion 17bb is with the spur gear 17ba connected. The spur gear 17ba stands with the spur gear 18 engaged by the connecting means with the operating handle 19 connected is. The engagement groove portion 17bb is designed to with the engagement projection 17ab co.

The coupling device 16 , the switching device 17 , the spur gear 18 and the operating handle 19 Form a manual actuator of the present invention.

Next, the operation of the drive device 10 described. In the normal, trouble-free operation is based on the entspre The drive signal indicates the forward or reverse torque of the motor 13 on the mechanism 14 transmitted to reduce the speed. In the mechanism 14 for reducing the speed, the rotational speed is determined by the transmission device 15 reduced to reduce the speed, and the rotational force is applied to the rotatable shaft 11c transfer. The coupling device 16 then sets the connection between the rotatable shaft 11c and the rotatable shaft 11b using the electromagnetic force is safe. The rotational force or rotational force of the rotatable shaft 11 is thus by the coupling device 16 on the rotatable shaft 11b transfer. Rotates the rotatable shaft 11b , so will the output wheel 11a which is connected to the end of the rotatable shaft 11b connected, turned. The spiral cables 34 , which with the output wheel 11a are engaged, are therefore driven.

The drive-side engaging portion 17a in this case, the coupling device 16 arranged adjacent. The rotational force of the rotatable shaft 11b will not be on the side of the handle 19 transfer.

Conversely, there is a fault, such as at the time of power interruption to the engine 11 or at the time of detection of a fault by the controller 40 , so the electromagnetic force of the clutch 16 interrupted, and the connection between the rotatable shaft 11c and the rotatable shaft 11b will be decoupled. The electromagnetic force of the drive-side engaging portion 17a is also interrupted. On the engagement projection 17ab is therefore acted, and it is in the direction of the engagement groove portion 17bb of the intervention section 17b the driven side moves by the pressure force. The engaging section 17ab is therefore with the engagement groove portion 17bb engaged.

In this state, the control handle 19 Turned in the normal direction or in the opposite direction, so is the rotational force of the spur gear 18 on the spur gear 17ba transferred, which with the spur gear 18 engaged. Since the drive-side engaging portion 17a and the engaging portion 17b the driven side are engaged with each other, the rotational force by the engaging portion 17b the driven side of the spur gear 18 on the engaging section 17a , which on the rotatable shaft 11b is attached, transferred. The rotatable shaft 11b is rotated in this way and the output gear 11a , which is on the rotatable axle 11b is attached, becomes integral with the rotatable shaft 11b turned. When the output wheel 11a is turned, so are the spiral cable 34 , which with the output wheel 11a are engaged, in the direction of rotation of the operating lever 19 turned.

The coupling 16 is decoupled at this time. Therefore, the rotation of the rotatable shaft 11b even if the rotatable shaft 11b is turned, not on the transmission device 15 transmitted to reduce the speed.

The drive device 10 directs the torque of the motor unit as described above 13 on the spiral cable 34 over and thereby drives the spiral cable 34 at. At the time of failure, the drive device conducts 10 the torque from the control lever 19 however, to the spiral cable 34 continue to the spiral cable 34 drive.

Holds the motor unit 13 because of the failure or stops it, the passenger can use the control handle 19 thus manually turn to the shielding 21 from the fully extended position to the fully retracted position. The passenger can use the operating handle 19 also manually turn to the shielding 21 extend from the fully retracted or retracted position to the fully extended or retracted position.

In the drive device 10 Further, according to the present embodiment, the electromagnetic force is applied to the coupling device at the time of normal operation 16 as well as on the switching device 17 applied. A handset 19a is in the drive device 10 provided to the electromagnetic force in the coupling device 16 as well as in the switching device 17 to interrupt by switching an internal circuit. Will the handset 19a operated, the electromagnetic force in the coupling device 16 as well as in the switching device 17 interrupted to manual operation by means of the control handle 19 to enable.

As described above, the disk W in the system S of the present invention can be operated by manually operating the operating handle 19 be placed during normal operation but also in the presence of a fault at any time in the transparent or clear view enabling state in which the disc W not with the Abschirmbahn 21 is covered.

The shielding 21 is detachable with the guide line in the embodiment shown above 27 and the push rods 28 (The rod of the present invention) through the connection between the hook and loop fasteners 6a and the hook and loop fasteners 6b connected. However, the present invention is not limited thereto. As in the 16A and 16B can be shown, for example, connection openings 7a in the free end of the shielding 21 be configured, and threads 7b can each through the connection openings 7a be inserted and on the leadership 27 and the push rods 28 be tied. Every thread 7b may be made of a cotton thread, a plastic thread, a copper wire or the like, as long as it can be cut, ie by pulling on the Abschirmbahn 21 by applying a predetermined force to the screening web 21 can be destroyed or torn.

16A shows the state in which the shielding 21 is in the fully extended position. The shielding 21 is in 16A with the management 17 and the push rods 28 by means of the threads 7b connected. In the in 16A the condition shown become the threads 7b slashed or torn when the passenger the shielding 21 towards the fully retracted position. The shielding 21 is thus by the management 27 and the push rods 28 , as in 16B shown, isolated. The shielding 21 is thus by the force or effect of the rolling-shading device 22 wound up to make the disc W transparent.

Is the shielding 21 with the management 27 and the push rods 28 by means of the threads 7b in a like in 16A and 16B connected way, so can the threads 7b advantageously be moved in the direction of the width when the Abschirmbahn 21 in the direction of the width of the Abschirmbahn 21 stretches to stretch the shielding 21 to follow.

As in the 17A and 17B Shown is the shielding membrane 21 also with the management 27 and the push rods 28 using detachable or removable snap fasteners (snaps) 8a . 8b get connected. The snap closures 8a . 8b can be made of synthetic resin or metal.

17A shows the fully extended state of the Abschirmbahn 21 , The snap closures 8a , which are at the shielding 21 are attached, stand here with the snap fasteners 8b , which with the leadership 27 and the push rods 28 are engaged, in engagement such that the Abschirmbahn 21 at the management 27 and the push rods 28 is attached. Pulls the passenger in this state, the shielding 21 towards the fully retracted position, the snaps will become 8a from the snap closures 8b solved. The shielding 21 is therefore from the management 27 and the push rods 28 , as in 17B shown, isolated. The shielding 21 is therefore due to the force or effect of the rolling-shade device 22 wound up to make the disc W transparent.

The engagement elements such as the hook and loop fasteners, the threads and the snaps can also be used in any combination to the Abschirmbahn 21 removable with the guide line 27 and the push rods 28 connect to.

In the embodiment shown above, the shielding web is 21 with the management 27 and the push rods 28 connected by means of the engagement elements. However, the present invention is not limited thereto. The shielding 21 For example, by means of the engagement elements removable with the sliding pieces 35 be connected. D. h., That the Abschirmbahn 21 removable with at least the guideway 27 and the push rod 28 or alternatively with the sliding pieces 35 can be connected by means of the engagement elements.

In the embodiment shown above, the guide line 27 and the push rod 28 (which serves as the rod or the shaft of the present invention) with the entire length of the free end of the Abschirmbahn 21 connected. However, the present invention is not limited thereto. As in 18 For example, only the left and right sides of the free end of the screen can be shown 21 each at the sliding pieces 35 be attached to the leadership 27 and the push rods 28 to omit or omit.

The free end of the shielding 21 in this case is pulled in the directions left and right to the shielding 21 to put under tension. The two-dimensional shape of the shielding membrane 21 is thus maintained by the applied voltage. The management 27 and the push rods 28 are no longer necessary in this way. The structure is therefore further simplified to contribute to a reduction in manufacturing costs as well as the weight.

In case of 18 is the shielding 21 further by means of removable engagement elements with the sliding pieces 35 connected. In the present case, the snap closures 8a . 8b used as the removable engaging elements. It should be noted that other detachable engagement elements such as the hook and loop fasteners and / or the threads can be used in the same way in this case.

18 shows the fully extended or extended state of the Abschirmbahn 21 , The passenger pulls the shielding 21 in this state towards the fully retracted NEN or retracted position, so are the snap closures 8a from the snap closures 8b solved. The shielding 21 is thus of the sliding pieces 35 separated. The shielding 21 is further affected by the force or effect of the rolling-shade device 22 wound up to make the disc W freely transparent.

As in the 19 and 20 shown. is, can left and right web-side engagement sections 21a each along the left and right lateral sides of the shielding sheet 21 are provided, each along the guide rails 31a . 31b extend. The web-side engagement sections 21a are from a lower surface of the Abschirmbahn 21 in a direction away from the disc W in front. Each web-side engagement section 21a is by folding the corresponding lateral side of the Abschirmbahn 21 and stitching the folded portion to achieve a predetermined stiffness and a predetermined flexibility, which includes rolling up the shielding sheet 21 around the roll-out shade device 22 allows, designed or manufactured.

The web-side engagement sections 21a however, are not limited to those described above. For example, separate web-side engagement sections 21a having the predetermined rigidity and the predetermined flexibility to the winding of the Abschirmbahn or 21 around the roll-out shading device 22 to allow around, in the lateral sides of the Abschirmbahn 21 be provided.

In the case of in the 19 and 20 Shielding shown 21 are the web-side engagement sections 21a continuously along the lateral sides of the Abschirmbahn 21 designed. The web-side engagement sections 21a alternatively, may be intermittently at predetermined intervals along the lateral sides of the screen 21 be designed.

It is desirable that the web-side engaging projections 21a in the radial direction of the coasting shading device 22 do not overlap when the web-side engagement sections 21a around the roll-out shade device 22 are wound up. The web-side engagement sections 21a can be spirally wound up in such a case when the web-side engaging portions 21a around the roll-out shade device 22 to be wrapped around. To achieve this, the shielding can 21 for example, have a trapezoidal shape, which has an increasing width from the base end to the free end. In this way, a portion of each web-side engaging portion 21a , which in the base end of the Abschirmbahn 21 is arranged when winding the Abschirmbahn 21 around the roll-out shade device 22 around closer to the middle of the width of the screen 21 leveled compared to a portion of the web-side engaging portion 21a , which at the free end of the shielding 21 is arranged. It is possible in this way, an overlap of the web-side engagement portion 21 in the radial direction of the coasting shading device 22 to avoid. Further, guide portions close to the coasting shading device 22 for guiding the web-side engagement sections 21a in the appropriate, suitable axial position of the coasting shading device 22 be provided.

21 is a cross-sectional view around the guide rail 31a . 31b around (for reasons of simplification in 21 only the guide rail 31a is shown). As described above, each guide rail 31a . 31b along the corre sponding front pillar 3 arranged. Every move piece 35 with which the push rod 28 and the shielding 21 is connected, along the corresponding guide rail 31a . 31b guided. A mount 206 is on a passenger compartment side of each front pillar 3 arranged. The front pillar 3 , the guide rails 31a . 31b and the displacement piece 35 are from the mount 206 covered so that the passenger can not see them. Every mount 206 has a slot 296a which extends along the corresponding front pillar 3 extends. The push rod 28 and the corresponding lateral side of the screen 21 are with the sliding piece 35 through the slot 206a connected.

Two guide elements 7 . 8th (Vehicle Body Side Engaging Sections) are on each mount 206 provided such that the guide elements 7 . 8th extend along the corresponding lateral side of the disc W. The guide elements 7 . 8th are parallel to the corresponding guide rails 31a . 31b between the corresponding mount 206 and the front pillar 3 arranged. The guide elements 7 . 8th each extend along a vehicle floor side edge (lower edge of the slot 206a in 21 ) and a vehicle top edge (upper edge of the slot 206a in 21 ) of the slot 206a of the mount 206 , The guide element 7 and the guide element 8th are arranged opposite each other and extend parallel to each other.

The guide element 7 slidably carries the corresponding web-side engaging portion 21a the shielding 21 , The web-side engagement section 21a when extending and retracting the shielding 21 along an inner surface of a guide groove 117a of the leader ments 7 guided. The guide element 8th is further provided to the lifting or lifting the Abschirmbahn 21 in a direction away from the guide element 7 to limit. In this way, the shielding 21 effective between the guide element 7 and the guide element 8th kept when the shielding 21 is extended or retracted, and the web-side engaging portion 21a will be along the guide groove 117a postponed and guided.

The web-side engagement sections 21a are as described above on the Abschirmbahn 21 provided, and the guide elements 7 . 8th are on the side of the front pillar 3 provided to slidably the web-side engaging portions 21a to hold and guide between them. When extending and retracting the shielding 21 keep all left and right lateral sides of the shielding track 21 their linear shape along the guide grooves 31a . 31b , Be the web-side engagement sections 21a when moving the shielding 21 along the guide grooves 31a . 31b not in the direction away from the guide elements 7 lifted, so are the guide elements 8th Furthermore, not necessary and can be omitted if desired.

As described above, the distance between the guide grooves increases 31a . 31b towards the lower ends of the guide grooves 31a . 31b to, and a width, which of the shielding 21 is to be covered in the direction of extending / retracting the Abschirmbahn 21 not constant. Will the shielding 21 , which is made of a stretchable material, from the roll-out shading device 22 rolled out or extended, so is the Abschirmbahn 21 in the direction of the width corresponding to the space between the guide grooves 31a . 31b stretched. The left and right side edges of the lower end of the Abschirmbahn 21 are each with the sliding pieces 35 are connected and therefore under force application in the direction of the width by the sliding pieces 35 in this case away from each other. The shielding 21 , which is stretched in the direction of the width, is kept under tension, which is the Abschirmbahn 21 withdraws to its original form.

When completely or partially extending or rolling out the Abschirmbahn 21 Therefore, tension on the shielding 21 exercised. Grasp the left and right guide elements 7 not in each of the left and right web-side engagement sections 21a a, so tend the sections of the Abschirmbahn 21 in which it is not the free ends of the Abschirmbahn 21 To do this, move toward the middle of the width of the disc W, as in 22 indicated by the dashed lines N, pull together.

In the present invention, such a contraction of the Abschirmbahn 21 which tends to contract due to the present tension, on the contrary, due to the engagement between the web-side engaging portions 21a and the guide elements 7 limited or limited. The left and right lateral sides of the screen 21 therefore become linear along the guide grooves 31a . 31b respectively extended as shown by the solid lines L in 22 is shown.

Is the shielding 21 fully extended or rolled out, so the shielding 21 substantially completely cover the disk W in this way, as in FIG 22 is shown. Unlike prior art solar shading systems, the uncovered triangular spaces are those of the screen 21 are not covered, left on the left and right lateral sides of the disc W or remained free. It is thus possible to limit the sunlight entering through the uncovered spaces into the passenger compartment and an increase in the temperature of the passenger compartment.

In the above modification or change, the web-side engaging portions 21a in the shielding 21 provided such that the web-side engaging portions 21a from the lower surface of the Abschirmbahn 21 projecting in the direction away from the disk W. As in 23 is shown, the web-side engaging portions 21a in an upper surface (one side of the disk W) of the shielding sheet 21 be provided to project toward the disc W. In this case, the guide elements should 7 , as in 23 shown to be provided on the side of the disc W, and guide elements 8c should each be opposite the guide elements 7 be provided. Every guide element 8c is in this case also integral with the corresponding guide rail 31a . 31b designed and extends from the guide rail 31a . 31b towards the middle of the width of the disc W.

Although not shown, there may further be two web-side engaging portions 21a on each of the left and right lateral sides of the screen 21 be provided such that the two web-side engagement sections 21a each of the upper surface and the lower surface of the Abschirmbahn 21 protrude in opposite directions.

In the present modification, each guide element 7 at the corresponding mount 206 intended. However, the present invention is not limited thereto. As in 24A ge shows, can guide sections 7c in one piece with the guide rails 31a . 31b be designed. The separate guide elements 7 can, as in 24B shown, alternatively directly with the front pillars 3 get connected.

In case of 24A is every leadership section 7c which the guide groove 117a has, in one piece with the corresponding guide groove 31a . 31b designed and extends from the guide rail 31a . 31b , Similar to the guide groove 117a of in 21 shown guide element 7 stands the guide groove 117a of the guide section 7c slidable with the corresponding web-side engaging portion 21a engaged to the shielding 21 between the fully extended position and the fully retracted position.

In case of 24B is every guide element 7 which is separate from the corresponding guide rail 31a . 31b is configured, directly with the corresponding front pillar 3 connected, and the guide groove 117a of the guide element 7 leads or guides the corresponding web-side engagement section 21a ,

In the above modification, a cross section of each web-side engagement portion is shown 21a and a cross section of each guide groove 117a semicircular. However, the present invention is not limited thereto. As in 25A 2, the cross section of each web-side engagement portion may be shown 21a and the cross section of each guide groove 117a be rectangular or the like.

As discussed above, the web-side engaging portion tends 21a to move toward the center of the width of the disk W (ie, toward the right side in FIG 25A ) due to the on the shielding 21 in the direction of the width applied voltage. The inner lateral surface (ie, a right lateral surface in FIG 25A ) of the web-side engaging portion 21a Therefore, it has better a flat surface than the curved or curved surface to the lifting of the web-side engagement portion 21a away from the guide element 7 to restrict and to the web-side engaging portion 21a by means of the guide element 7 to hold and guide. In case of 25A have the web-side engagement sections 21a and the guide grooves 117a thus the rectangular cross-section to a sliding connection between each engaging portion 21a and the corresponding guide groove 117a to make contact with a flat surface between them.

In case of 25B have the web-side engagement section 21a and the guide groove 117a a triangular cross-section. In case of 25C have the web-side engagement section 21a and the guide groove 117a a rectangular cross-section. In 25C is in a lower surface of the web-side engaging portion 21a Further, a groove configured, and in a base of the guide groove 117a a ridge is configured to be a sliding engagement between the groove of the web-side engaging portion 21a and the bridge of the guide groove 117a to achieve. The web-side engagement section 21a can be effective in this way by means of the guide element 7 be guided. As it is in 25C The case is any other type of groove in the shielding 21 be configured as a web-side engagement portion, and a corresponding web can in the guide element 7 be designed to interact with this groove.

In the second embodiment, the sun visor system S of the present invention is mounted on a door window (side window) of the vehicle 1 executed. The system S of the second embodiment is, in particular, on a right front door 101 (hereinafter simply as a door 101 ). Components which are the same as those discussed above with respect to the first embodiment are designated by the same reference numerals and will not be further described.

27 is a side view of a right side door 101 seen from the side of the passenger compartment, and a section of the door 101 is fragmented or shown in excerpts for the sake of clarity. 27 further shows the Abschirmbahn 121 of the system S, which is held in an intermediate position between the fully retracted position and the fully extended position.

The door 101 has a passenger compartment side of a door panel 102 connected door panel 104 on. A window or window frame 103 is on an upper side of the door panel 102 designed. A mount 105 is with a passenger compartment side of the window frame 103 connected. The mount 105 is with the passenger compartment side of the door frame 103 connected so that the enclosure 105 along a front frame 103a , an upper frame 103b and a rear frame 103c of the window frame 103 extends.

It should be noted that the enclosure 105 and the door panel 104 can be designed in one piece, this should be desired. The front frame 103a and the rear frame 103c are intended as frames, which are vertical from the door panel 102 extend. A window glass or a glass pane 106 is for covering an opening 102 arranged, which from the window frame 103 is formed. The window glass 106 is moved vertically by means of a drive device (not shown) for closing / opening the opening 102 emotional.

The opening 102 of the window frame 103 has a substantially trapezoidal shape so that a width of an upper side of the opening 102 shorter than a width of a lower side of the opening 102 is. In the window frame 103 According to the present invention, the front frame extends 103a from the main body of the door panel 102 sloping and upwards, and the rear frame 103c extends in the vertical direction from the main body of the door panel 102 up. A connection between the front frame 102 and the upper frame 103b has a round shape, which has a predetermined curvature.

The system S of the present invention is on the door described above 101 attached and has a drive device 110 , a roll-out shading mechanism 120 and a guide device 130 on.

The drive device 110 is between the door panel 104 and the door panel 102 arranged. The drive device 110 has a motor unit 111 and a mechanism 112 to reduce the speed. A cylindrical coil 113 is with an exit side of the mechanism 112 connected to reduce the speed. The sink 113 Wraps a cable (transmission element) 132 on or moves this. Any suitable among the various motors such as DC motors, brushless motors and ultrasonic motors can be used as motor unit 111 be used. An operating switch 114 , which has a position for lifting and a position for lowering, is connected to the drive device 110 connected. The passenger activates the control switch 114 in the lifting position or the lowering position, so the engine unit 111 supplied with electricity to the coil 113 in a normal direction or an opposite direction for driving the system S to rotate.

During normal operation, a torque is generated by the motor unit 111 on the spool 113 transfer. However, if an error occurs, the connection is interrupted, and the torque of the motor unit 111 therefore will not be on the coil 113 transfer. If an error occurs, then the rotational force of an operating lever 119 through the mechanism 112 to reduce the speed on the spool 113 transfer. The passenger can thus the shielding 121 by pressing the operating lever 119 extend or retract.

The roll-out shade mechanism 120 has a roll-out shading device 122 , Roll-out shade holder 126 and a shielding track 121 on. The roll-out shade holder 126 are respectively at opposite ends of the coasting shading device 122 arranged and rotatably support the Ausroll-shading device 122 , A base end of the shielding membrane 121 is with the roll-out shading device 122 connected, and the shielding 121 covers the opening 102 of the window frame 103 ,

The entire shielding 121 The present embodiment is similar to the shielding sheet 21 the first embodiment stretchable or stretchable.

The roll-out shade device 122 is a cylindrical element. In a closed state of the window glass 106 is the roll-out shade device 122 along the front frame 103a and the upper frame 103b of the window frame 103 curved in such a way that the coasting-shading device 122 along an upper edge of the window glass 106 is arranged. The roll-out shade device 122 is between the window frame 103 and the mount 105 arranged. A slot 105a , which of the opening 102 is facing, is in the mount 105 designed. The shielding 121 extends through the slot 105a and extends from the coasting shading device 122 to the opening 102 to cover. The roll-out shade device 122 may be arranged not only along a straight line, but also along the curvature of the edge of the window frame 103 , Thereby, a degree of flexibility of the coasting-shading device becomes 122 increases to accommodate the Ausroll-shading device 122 in a small space, and to make the system S compact. The system S can also be arranged at a location or location where this is not possible in the previously proposed systems.

Similar to the first embodiment, the coasting shading device 122 the central axis of the present embodiment 22a , the spiral spring 22b , the penholder 22c and the rotatable rod 22d on. The rotatable rod 22d has the coupling rods 23 , the connections 24 and the center poles 25 which are interconnected on. As with the roll-out shade device 22 The first embodiment is the coasting shading device 122 The second embodiment thus flexible or elastic.

A clamp or clamp 126a is on a vehicle front side facing the upper frame 103b arranged. the clamp 126a is about the longitudinal center of the roll-out shading device 122 arranged around. the clamp 126 Further, slidably engages an outer surface of the coasting shading device 122 and considers this to be a displacement of the coasting shading device 122 during the rotation of the coasting shading device 122 to restrict.

As in the 27 and 28 is shown, the guide device 130 the present embodiment, a guide rail 131 , a displacement piece 135 and a cable 132 on. The guide rail 131 is between the rear frame 103c and the mount 105 arranged. The sliding piece 135 will be in the guide rail 131 guided to move in the longitudinal direction of the guide rail 131 to move. The cable 132 is in the guide rail 131 added, and one end of the cable 132 is with the sliding piece 135 connected.

The sliding piece 135 has a displacement section 135a and a shaft connecting portion 135b on. The shaft connecting portion 135b is integral with the sliding section 135a designed. A rear end of the vehicle facing side of a free end of the Abschirmbahn 121 is on the shaft connecting portion 135b attached. A snap closure 8a is at the shielding track 121 attached, and a snap closure 8b is on the shaft connecting portion 135b attached. The shielding 121 is with the sliding piece 135 by the interaction between the snap closure 8a and the snap closure 8b connected. The connection between the shielding membrane 121 and the sliding piece 135 is not on the snap closures 8a . 8b limited and can be achieved by any other fasteners such as the hook and loop fasteners or threads discussed with reference to the first embodiment. The sliding section 135a is displaceable in the guide rail 131 which has a slot in an inner lateral side (ie, the side of the disk center) of the guide rail 131 having.

The cable 132 is with the sliding section 135a connected at one end. The cable 132 extends or passes through the guide rail 131 and gets through the pulley 133 to the drive device 110 guided. The other end of the cable 132 is with the coil 113 the drive device 110 connected, and the drive device 110 can the cable 132 around the coil 113 to wind around. In the present embodiment, the cable 132 through the role 133 to the drive device 110 guided. However, the present invention is not limited thereto. Instead of the role 133 Any other suitable intermediate element can be used or arranged to the cable 132 to the drive device 110 to lead. For example, an element having a tube or a groove may be used as the other intermediate element. The cable 132 is guided in such a case through the tube or along the groove to a sliding movement of the cable 132 along the tube or groove. An element having a groove may be further arranged to change the guide direction at a deflection point, at which a guide direction of the cable 132 will be changed.

The operation of the system S of the present embodiment will be described below. As discussed above, the drive device becomes 110 rotated in the normal direction such that the coil 113 is rotated in the normal direction when the passenger is the service switch 114 into the lowering position brings. The cable 132 is wound up in this way, ie it will be around the coil 113 rolled up.

When the cable is wound up, the sliding piece moves 135 along the guide rail 131 downward.

When the sliding piece 135 moved down, so is the Abschirmbahn 121 by means of the sliding piece 135 pulled down. The roll-out shade device 122 thus turns in the normal direction, and the shielding 121 gets through the slot 135 further extended or rolled out. On the roll-out shading device 122 is here by means of the coil spring 22b a rotational force in the winding direction of the Abschirmbahn 121 applied. The shielding 121 thus becomes the coasting shading device 122 pulled out while a suitable tension by means of the coil spring 22b on the shielding 121 is applied.

The shielding 121 is like in 29 shown stretchable especially in the direction of the width. The width of the opening 102 It also moves towards the bottom of the opening 102 to. Moves the sliding piece 135 down, so can the shielding 121 stretched in the direction of the width to the increasing width of the opening 102 to follow. In system S, the window frame can 103 which has the essentially trapezoidal opening 102 has, substantially completely through the Abschirmbahn 121 be covered.

The passenger can use the shielding 121 by maintaining the position of the control switch 114 Lower in the lowered position to a desired position. Will the operating switch 114 reset to a neutral position, so the operation of the drive device 110 interrupted. The shielding 121 can in this position by means of a in the drive device 110 provided latching mechanism (for example, a clutch) are held. The passenger wants the shielding 121 to lift, the passenger operates the control switch 114 in the lifting position. The drive device 110 is rotated in this way in the opposite direction, and by means of the spiral spring 22 In the winding direction applied torque is the shielding 121 around the roll-out shade device 122 wound. If the sliding piece 135 reaches its upper end position, so is the Abschirmbahn 121 in the mount 105 added.

In this embodiment, limit switches may be at the upper end position, the lower end position, and an intermediate position) of the movable portion of the slider 135 be provided. The power supply of the drive device 110 can be interrupted if a corresponding limit switch is activated.

As described above, in the system S, substantially the entire opening 102 of the window frame 103 to be covered. The system S can fulfill its shadow function in this way. It is thus possible to restrict the sunlight entering the passenger compartment to limit an increase in the temperature in the passenger compartment. In the present embodiment, the system S is further on the front right door 101 realized. However, the present invention is not limited thereto. The system S may be provided on all side windows. The side windows include not only the door panes but also all other side windows which are immovably connected to the side of the vehicle or which are movably received on the vehicle side. An increase in the temperature of the passenger compartment can be further advantageously limited in this way.

The material of the shielding membrane 121 can also be replaced by any suitable material with a suitable light transmission such that the system S has the function of a smoke film.

In the system S of the present embodiment, the coasting shading device is 122 further along the front frame 103a and the upper frame 103b of the window frame 103 arranged. The shielding 121 can therefore from the top of the opening 102 be lowered to the opening 102 to cover. The system S can serve as a sun visor in this way. The system S of the present invention can thus serve at the same time as a sun visor and as shading.

The passenger can use the shielding 121 fully extend when the glass pane 106 completely lowered or retracted. The system S can thus be used as an insect screen net or web to restrict the entry of insects into the passenger compartment. Is the shielding 121 lowered or extended to a predetermined position, so the shielding 121 Avoiding wind, which otherwise when driving on an upper side of the passenger body hits as the head of the vehicle.

In system S are the drive device 110 , the roll-out shading mechanism 120 and the guiding device 130 between the door panel 102 and the door panel 104 or between the door panel 102 and the mount 105 arranged. If the system S is not in use, the system S does not disturb the passenger. The system S is further arranged not in a vehicle body side but in the door side. The system S thus does not interfere with the operation of, for example, a curtainsealed airbag to keep the vehicle safe.

An electrical structure (not shown) of the system S of the second embodiment may be the same as that described with reference to FIG 12 be described for the first embodiment. In such a case, the operation switch 114 the second embodiment similar to the operation switch 41 the first embodiment connected to the controller, and the motor or the motor unit 111 is connected to the controller. The shielding 121 This can be done by manual operation of the control switch 140 based on the control signal from the control switch 114 extended or retracted. The shielding 121 may alternatively by the motor unit 111 by outputting a drive signal from the controller to the motor unit 111 for driving the motor unit 111 in the normal direction or in the opposite direction based on measuring signals from the temperature sensor, the optical sensor, the position sensor and / or the gear position sensor automatically extended or retracted. The extension and retraction of the shielding 21 the windscreen (and possibly the rear window) and side windows can be controlled by a single control if so desired.

Also, in the system S of the second embodiment, the passenger can make the connection between the snap closure 8a and the snap closure 8b , which connects between the shielding 121 and the sliding piece 135 produces, solve when the drive device 110 for example, when completely extended Abschirmbahn 121 failed. By loosening the connection between the snap closure 8a and the snap closure 8b will the shielding 121 due to the spiral spring acting in the direction of winding 22b around the roll-out shade device 122 wound or wound up. The opening 102 can thus be brought into the free or transparent state in which the opening 102 not from the shielding 121 is covered.

In a manner as described above, the passenger can also control the operating lever 119 turn around the pin 213 to turn and thereby the frame 232 move up or down. The shielding 121 is thus extended or retracted. As in the case of the first embodiment, the manual switch can also be used in this case 19a in the drive device 110 be provided to the manual operation by the operating lever 119 even during normal operation.

The passenger can also use the operating lever 119 turn around the coil 113 to turn and thereby the cable 120 around the coil 113 in such a way or unwind that the shielding 121 extended or retracted. As in the first embodiment, the handset 19a in the drive device 110 be provided to the manual operation by means of the operating lever 119 even during normal operation.

The cable 132 is in the second embodiment of the coil 113 the drive device 110 wrapped around the sliding piece 135 to move vertically. However, the present invention is not limited thereto. Instead of the cable 132 could be a resin frame 232 and a cone 213 used as a transmission element to the sliding piece 135 , as in 30 shown to move vertically.

As in 30 is shown, the guide device 130 a guide rail 231 , the sliding piece 135 and the frame 232 on. The guide rail 231 is between the rear frame 103c and the mount 105 arranged. The sliding piece 135 is by means of the guide rail 231 guided to get along the guide rail 231 to move. An upper end of the frame 232 is with the sliding piece 135 connected, which by means of the guide rail 231 to be led. Instead of the coil 113 is the pin 213 , which with the frame 232 is engaged with the output side of the drive devices connected.

The shielding 121 and the displacement piece 135 are by removable or detachable elements such as the snap closures 8a . 8b connected with each other. The operating lever 119 is also with the drive device 110 connected.

With the embodiment shown above, the pin 213 rotated in the normal direction and in the opposite direction when the drive device 110 is rotated in the normal direction or in the opposite direction, and the rack 232 becomes thereby along the guide rail 231 moved up or down. The sliding piece 135 which is connected to the upper end of the frame 232 is connected moved up or down to the shielding 121 to move up or down, which with the sliding piece 135 connected is.

Also, in the system S of the second embodiment, the passenger can make the connection between the snap closure 8a and the snap closure 8b , which connects between the shielding 121 and the sliding piece 135 produces, solve when the drive device 110 for example, when completely extended Abschirmbahn 121 failed. By loosening the connection between the snap closure 8a and the snap closure 8b will the shielding 121 due to the spiral spring acting in the direction of winding 22b around the roll-out shade device 122 wound or wound up. The opening 102 can thus be brought into the free or transparent state in which the opening 102 not from the shielding 121 is covered.

In a manner as described above, the passenger can also control the operating lever 119 turn around the pin 213 to turn and thereby the frame 232 move up or down. The shielding 121 is thus extended or retracted. As in the case of the first embodiment, the manual switch can also be used in this case 19a in the drive device 110 be provided to the manual operation by the operating lever 119 even during normal operation.

The cable 132 in the second embodiment is directly by means of the drive device 110 rolled up (ie the coil 113 the drive device 110 ). However, the present invention is not limited thereto. As in 31 is shown, similar to the first embodiment, for example, a spiral cable 334 by means of the drive device 110 are driven. The roll-out shade device 122 is along the front frame 103a and the upper frame 103b arranged and curved. The shielding 121 and the displacement piece 135 are by removable or detachable engagement elements such as the snap closures 8a . 8b connected with each other.

The guiding device 130 is in the back frame 103c arranged. The guide device has the guide rail 131 , the sliding piece 135 , a hollow cable ladder 323 and the spiral cable 334 on. The cable conductor 323 is with the lower end of the guide rail 131 connected. The spiral cable 343 serves as a transmission element, which is in the cable ladder 332 arranged and in the cable ladder 332 is displaceable. The lateral side of the free end of the shielding membrane 121 is with the sliding piece 135 connected.

The cable line 332 is at a predetermined curvature around the lower end of the rear frame 103c bent and stands forward (in 31 in the direction to the left). A cable conductor holder 333 is also provided to the cable ladder 332 on the lower side of the window frame 103 to keep. The cable conductor 332 is in the cable ladder 333 Partially cut along its length, and the spiral cable 334 is exposed in the cut-out section.

The drive device 110 has the motor unit and the mechanism for reducing the speed and is with the cable conductor holder 333 connected. An exit wheel 313 is with an output side (for example, an output shaft) of the drive device 110 connected so that the output wheel 313 projecting in the lateral direction of the vehicle. The output wheel 313 is attached to the spiral cable 334 which is in the cable ladder 333 is exposed to be engaged. The spiral cable 334 and the drive device 110 , which with the spiral cable 334 was engaged to the spiral cable 334 are the same as those discussed in the first embodiment. The operating lever 119 is also with the drive device 110 connected in a manner similar to that of the first embodiment.

The spiral cable 334 is further in a guide groove of the guide rail 131 inserted to the sliding piece 135 and the spiral cable 334 , which with the sliding piece 135 is connected to lead slidably or slidably.

The drive device 110 and the guiding device 130 are constructed in the manner described above. When the drive device 110 is rotated in the normal direction or in the opposite direction, so is the spiral cable 334 in the cable ladder 332 and the guide rail 131 led in the appropriate direction. The sliding piece 135 , which is at the end of the spiral cable 334 is attached, therefore, between the upper end and the lower end of the guide rail 131 emotional. The stretchable shielding membrane 121 is therefore between the upper end and the lower end of the opening 102 of the window frame 103 drive out or retracted, where it expands or contracts in the direction of the width.

Also in this modification of the system S, the passenger can in case of failure of the drive device 110 for example, in the fully extended state of the shielding 121 the connection between the snap closure 8a and the snap closure 8b which the shielding 121 and the displacement piece 135 connect with each other, pick up. The shielding 121 is going through the lifting of the connection between the snap closure 8a and the snap closure 8b due to the action of the coil spring 22b acting in the winding direction to the coasting shading device 122 wound. The opening 102 can therefore be placed in the state in which the opening 102 not from the shielding 122 is covered.

In one of the similar ways described above, the passenger can also control the operating lever 119 turn to the output gear 313 to turn and thereby the spiral cable 334 to move forward or backward. The shielding 122 is thus extended or retracted. As in the first embodiment, the handset 19a further in the drive device 110 be provided to the manual operation by the operating lever 119 even during normal operation.

In the second embodiment, the guide device is 130 only in the back frame 103c intended. Alternatively, two guide devices each in the front frame 103a and in the back frame 103c , as in 32 be shown provided. In this modification or modification are also two drive devices 110 intended. One of the drive devices 110 and one of the guiding devices 130 are on the left side of the roll-out shading device 122 provided, and the other of the drive devices 110 and the other of the guiding devices 130 are on the right side of the roll-out shading device 122 intended. One of the guide rails 131 is due to the front frame 103a , and the other guide rail 131 is at the rear frame 103c intended. Every move piece 135 is slidable in the corresponding guide rails 131 arranged. The left and right sides of the free end of the Abschirmbahn 121 are each with the sliding pieces 135 connected.

The shielding 121 is with the moving pieces 135 by removable engagement elements such as the snap closures 8a . 8b connected. The operating lever 119 is further with each of the drive devices 110 connected.

An end of each cable 132 is with the appropriate sliding piece 135 connected. Every cable 132 is in the corresponding guide groove 131 recorded and becomes the corresponding drive device 110 guided.

The roll-out shade mechanism 120 has the coasting-shading device 122 on. The roll-out shade device 122 is in the upper frame 103b provided and extends along a straight line or a slightly curved line.

Will the operating switch 114 actuated so rotate in this design in the system S, the two drive devices 110 synchronously in the normal direction or in the opposite direction. The displacements 135 , which with the cables 132 are connected in this way each along the guide rails 131 guided. As in the first and second embodiments, the stretchable Abschirmbahn 121 this stretched in the direction of the width to the entire opening 102 cover.

Also in this modification of the system S, the passenger can in case of failure of the drive device 110 for example, in the fully extended state of the shielding 121 the connection between the snap closure 8a and the snap closure 8b which the shielding 121 and the displacement piece 135 connect with each other, pick up. The shielding 121 is by unlocking the connection between the snap closure 8a and the snap closure 8b due to the effect of the spiral spring 22b which acts in the winding direction to the Aasroll shading device 122 wound. The opening 102 can therefore be placed in the state in which the opening 102 not from the shielding 122 is covered.

In one of the similar ways described above, the passenger can also control the operating lever 119 turn to the output gear 313 to turn and thereby the spiral cable 334 to move forward or backward. The shielding 122 is thus extended or retracted. As in the first embodiment, the handset 19a further in the drive device 110 be provided to the manual operation by the operating lever 119 even during normal operation.

Again alternatively, the two guide devices 130 , as in 33 shown in the front frame 103a or in the rear frame 103c be provided. The spiral cables 334 can like that in 31 also shown by means of the drive device 110 be driven. Also in this modification or change is the Abschirmbahn 121 with the moving pieces 135 by removable engagement elements such as the snap closures 8a . 8b connected. The operating lever 119 is with the drive device 110 connected.

In the in 33 shown modification are two cable conductors 332a . 332b each with lower ends of the two guide rails 131 connected, each in the front frame 103a and in the back frame 103c are provided. The cable ladder 332a . 332b are each below a predetermined Curvature at the lower ends of the front and rear frames 103a . 103c bent and extend in the directions backwards (in 33 right) and in front (in 33 Left). At the bottom of the window frame 103 are the two cable ladders 332a . 332b arranged in the vertical direction and extend parallel to each other. The cable ladder holder 333 is further provided to integrally both cable conductors 332a . 332b to hold, which are parallel to each other on the lower side of the window frame 103 are arranged. The cable ladder 332a . 332b are in the cable ladder 333 each partially cut along its length, causing the spiral cable 334 in the cut-out sections of the cable ladder 332a . 332b exposed. An end of each spiral cable 332a . 332b is in the guide groove of the corresponding guide rail 131 inserted and with the appropriate sliding piece 135 connected.

The drive device 110 and the guiding devices 130 are constructed in the manner described above. Every spiral cable 334 is therefore in the associated or corresponding cable ladder 332a . 332b and the corresponding guide rail 131 guided when the drive device 110 is rotated in the normal direction or in the opposite direction. Every move piece 135 , which is at the end of the corresponding spiral cable 334 is fixed, is thus between the upper end and the lower end of the corresponding guide rail 131 emotional. As a result of this movement, the stretchable Abschirmbahn 121 between the upper end and the lower end of the opening 102 of the window frame 103 extended or retracted, wherein it is stretched in the direction of the width.

Also in this modification of the system S, the passenger can in case of failure of the drive device 110 for example, in the fully extended state of the shielding 121 the connection between the snap closure 8a and the snap closure 8b which the shielding 121 and the displacement piece 135 connect with each other, pick up. The shielding 121 is by unlocking the connection between the snap closure 8a and the snap closure 8b due to the action of the coil spring 22b acting in the winding direction to the coasting shading device 122 wound. The opening 102 can therefore be placed in the state in which the opening 102 not from the shielding 122 is covered.

In one of the similar ways described above, the passenger can also control the operating lever 119 turn to the output gear 313 to turn and thereby the spiral cable 334 to move forward or backward. The shielding 122 is thus extended or retracted. As in the first embodiment, the handset 19a further in the drive device 110 be provided to the manual operation by the operating lever 119 even during normal operation.

The system S of the second embodiment may also be incorporated in one of 34 and 35 be modified as shown.

In the in the 34 and 35 shown modification of the system S, the system S, the drive device 110 and a mechanism 140 to roll out the web. The drive device 110 indicates the motor unit 111 and the mechanism 112 to reduce the speed. The sink 113 to which the cable 132 can be wound, that is rolled up, is with the output side of the drive device 110 connected.

The mechanism 140 for unrolling the web has the Abschirmbahn 121 and swiveling frame 301 . 302 on. A lower side and a rear side of the shielding 121 are each with the swiveling frame 301 . 302 connected. Each hinged frame 301 . 302 is configured as a rigid linear element and has an opening slot which extends along its length on an upper side of the pivotable frame 301 . 302 in 34 extends such that each hinged frame 301 . 302 has a U-shaped cross-section.

A front end of the hinged frame 301 is by means of a holding pin 304a rotatably supported, which at a lower end of the front frame 103a is arranged. A rear end of the hinged frame 302 is rotatable by means of a retaining pin 304c supported, which at a connection between a rear end of the upper frame 103b and an upper end of the rear frame 103c is arranged. A slot 302a which has a predetermined length is in a front end of the pivotal frame 302 in a longitudinal direction of the pivotable frame 302 designed. A retaining pin 304b is in a rear end of the hinged frame 301 provided such that the retaining pin 304b in the slot 302a of the hinged frame 302 is recorded. The swiveling frame 301 and the swivel frame 302 are thus by means of the holding pin 304b connected together so that relative rotation between them is possible. Moves the retaining pin 304b in the longitudinal direction of the pivotable frame 302 in the slot 302a so can the swivel frame 301 and the swivel frame 302 each around the retaining pin 304a . 304c swing.

A leaf spring (printing device) 303 is in the upper end of the rear frame 103c arranged to a top surface of the rear end of the pivotable frame 302 to press down. The swiveling frame 302 thus receives a compressive force of the spring 303 which the pivoting frame 302 counterclockwise around the retaining pin 304c suppressed. The swiveling frame 302 and the swivel frame 301 , which are connected to each other so that a relative rotation between them is possible, therefore, the pressing force in a rolling direction. Although the leaf spring 303 is used as a printing device, any other suitable means, such as a coil spring or an elastic element, can be used as a printing device. The printing device may further comprise the frame 301 instead of the frame 302 Press or force into the coasting direction.

A role 333a is at the top of the front frame 103 arranged and a roll 333b is at the bottom of the front frame 103 arranged. A catch 301 is also at the rear end of the pivotable frame 301 arranged. One end (upper end in 34 ) of the cable 132 is with the hook 301 connected. The cable 132 gets along the front frame 103a through the roles 333a . 333b led, and the other end of the cable 132 is with the coil 113 the drive device 110 connected. The drive device 110 is provided in this modification to the vehicle front, and the cable 132 is along the front frame 103a arranged. However, the present invention is not limited thereto. The drive device 110 can alternatively near the rear frame 103c be provided, and the cable 132 can be different from the coil 113 the drive device 110 to the hook 301 extend by means of corresponding (not shown) roles. The drive device 110 and the roles 333a . 333b form a winching device.

The shielding 121 has a predetermined shape. In the in 35 shown state is a front side of the shielding 121 on the front frame 103a secured, and an upper side of the Abschirmbahn 121 is at the top frame 103b attached. The lower side of the shielding membrane 121 is also on the pivotable frame 301 attached, and the rear side of the shielding 121 is on the pivoting frame 302 attached. In the fully retracted state of the shielding 121 is the hinged frame 301 along the front frame 103a arranged, and the hinged frame 302 is along the top frame 103b arranged. Because the cross section of each hinged frame 301 . 302 U-shaped, everyone can swivel frame 301 . 302 the shielding 121 record here.

Will the drive device 110 in the normal direction from the in 34 turned state, so will the cable 132 unwound in the construction shown above and from the spool 113 extended. There on the swivel frame 302 the compressive force of the leaf spring 303 is applied in the unwinding causes the unwinding or unwinding of the cable 132 the swinging out of the swiveling frame 301 . 302 , The shielding 121 is thus extended to the opening 102 to cover under stretching. Even in the middle of the way to the fully extended position, ie to the fully extended position, the Abschirmbahn 121 the opening 102 cover, wherein a predetermined voltage is applied. The retaining pin 304b moves in the slot 302a , 35 shows a state in which the pivotal frame 301 . 302 be kept in the fully unrolled position.

In the in 35 shown state is the cable 132 against the pressure force of the leaf spring 303 around the coil 113 rolled up when the drive device 110 is rotated in the opposite direction. The shielding 121 is as described above in the fully retracted position in the pivoting frame 301 . 302 added.

In the in the 34 and 35 shown modification are the two pivoting frame 301 . 302 in the window frame 103 arranged in a pivotable manner. On the swiveling frame 301 or the hinged frame 302 Alternatively, however, can also be dispensed with. The opening 102 can in particular in a case in which only the swiveling frame 301 is provided to the retaining pin 304a from the front frame 103a towards the side of the opening 102 to be pivoted, by means of the stretchable Abschirmbahn 121 by pivoting the hinged frame 301 towards the opening 102 to be covered. In a case where only the hinged frame 302 is provided to the retaining pin 304c between the upper front frame 103a and the rear frame 103c In addition, essentially the entire opening can be pivoted 102 by means of the stretchable shielding membrane 121 by pivoting the hinged frame 302 towards the rear frame 103c to be covered.

36 Fig. 10 shows a modification of the coasting shading device 122 the second embodiment. The following modification is also to the coasting shading device 22 of the first embodiment, for the sake of simplicity, such modification will be made to the coasting shading device 22 the first version However, not described. In the roll-out shade device 22 of the 36 is the penholder 22c ( 9 ) at one end of the coasting shading device 22 arranged, and one end of the spring holder 22c is by means of the connection 24 with the adjacent central rod 25b connected. The central axis 22a and the coil spring 22b ( 9 ) are inside the spring holder 22c arranged. The lower end of the coil spring 22b is on the penholder 22c attached, and the upper end of the coil spring 22b is at the central axis 22a attached. The roll-out shade device 22 receives in the winding direction of the coasting shading device 22 a torque from the coil spring 22b ,

A curvature of the central axis 22a varies in 36 in longitudinal regions (longitudinal regions) R1-R5. Especially in the areas R1, R5 the curvature is relatively small (ie it has a comparatively large radius of curvature). In the regions R2, R4 there is a mean curvature (ie it has a mean radius of curvature). In the region R3 the curvature is relatively large (ie it has a relatively small radius of curvature).

Because of these curvatures becomes a long central rod 24d (or a long side bar 23 ) is used in the areas R1, R5, which have the comparatively small curvature. In the regions R2, R4, which have the mean curvature, becomes a central central rod 25b , which has a mean axial length used. In the region R3, which has the relatively large curvature, also becomes a short central rod 25c used, which has a relatively small axial length.

Corresponding to the curvature of, for example, the window frame along which the coasting shading device 22 arranged, are selectively the long central rod 25d (or the long side bar 23 ), the central central rod 25b and the short central pole 25c used. The shape of the roll-out shading device 22 can thus be easily adapted to the curvature, for example, the window frame. The central bars 25b . 25c . 25d , the connections 24 and the side bars 23 experience less resistance in this construction when the central rods 25b . 25c . 25d , the connections 24 and the side bars 23 around the central axis 22a rotate, which allows a slight turn. In this way, the noise level is advantageously lowered. The use of long central rods 25d also allows a reduction in the number of components.

In case of 36 become the three types of central rods 25b . 25c . 25d (and the side bars 23 ) used. However, the present invention is not limited thereto. It is only necessary to use two or more types of central bars (and side bars).

Furthermore, only the short central rods can 25c without use of the middle and long central rod 25b . 25d be used. With this structure, the coasting shading device 122 be easily adapted to the curvature and gently rotated while reducing the noise level.

In case of 36 is the axial length of each connection 24 short (shorter than each of the central rods 25b-25d ) and constant. Alternatively, two or more types of joints having different axial lengths may be used based on the curvature of, for example, the window frame.

In the first and second embodiments, each connection is 24 and the adjacent central bar 25 connected together so that the rectangular engagement projections 25a the central bars 25 loosely into the rectangular engagement recesses 24a the connection 24 are inserted as in 37 is shown.

Each end of the central rod 25 has the two engaging projections 25a , which are arranged offset by 180 ° in the circumferential direction ( 10 ). The central pole 25 can relative to the connection 24 in a plane which extends through the two engagement sections 25a extends in the axial direction, ie which is perpendicular to the plane of 37 stands, moves and pans. The central pole 25 especially relative to the compound 24 in a direction perpendicular to a direction Y in 37 swing.

A circumferential width of each engagement recess 24a is greater than a circumferential width of the corresponding engagement projection 25a such that a predetermined space or gap A is defined between an engagement surface of the engagement recess 24a and an engagement surface of the engagement projection 25a on a peripheral side of the engagement recess 24a is determined. Due to the space provided or gap A, the central rod 25 relative to the connection 24 within a predetermined angular range in the direction Y (ie, the direction in a plane perpendicular to the above-mentioned plane passing through both engagement protrusions 25a extending in the axial direction) are pivoted. If the space A is increased, then the pivotable angle of the central rod 25 relative to the connection 24 enlarged in the Y direction.

The curvature of the roll-out shading device 22 . 122 is not about the length of the off roll-shading device 22 . 122 constant. A size of the space A must therefore correspond to the curvature of the roll-out shading device 22 . 122 be adjusted. In particular, in a region of small curvature, the size of the space A can be set to a comparatively low value. However, in a region of large curvature, the size of the space A must be increased to be larger than the coasting shading device 22 . 122 to allow adaptation to the large curvature. By means of the adjustment of the space A in the manner and manner described above, the curvature of the roll-out shading device 22 . 122 be set appropriately in each axial region thereof.

The central pole 25 can pivot in the Y direction as well as in the direction perpendicular to the Y direction as described above. The roll-out shade device 22 . 122 can therefore turn gently.

The shape of each engagement recess 24a and the shape of each engagement projection 25a are not limited to the rectangular shapes, which in 37 are shown. For example, each engagement recess 24a and every interventional advantage 25a have trapezoidal forms, as in 39 is shown.

As in 40 a plurality of engagement recesses may further be shown 24a and a plurality of engaging projections 25a be provided. In 40 are four engaging projections 25a arranged at 90 ° intervals in the circumferential direction, and also at 90 ° intervals are four engagement recesses 24a provided in the circumferential direction. Similar to the construction 37 In this design, the central rod can be 25 in the plane perpendicular to the plane of the 40 relative to the connection 24 move and swing. This means that the central rod 25 relative to the connection 24 in the direction perpendicular to the Y direction in 40 can swing. Due to the space provided or gap A, the central rod 25 further relative to the compound 24 Pan within a predetermined angular range in the Y direction. The number of engagement recesses 24a may alternatively be set to three, or alternatively fixed at five or more. The number of engagement projections 25a Alternatively, it may alternatively be set at three or more alternatively five or more. Even in this case, the pivotal movement described above is the central rod 25 relative to the connection 24 possible.

In some cases, however, the space A could be that between each engagement projection 25a and the corresponding engagement recess 24a is provided, a delay in the transmission of torque to the central rod 25 cause. This delay in the transmission of torque has no significant influence on the operations of extension and retraction. However, this delay could potentially cause a time delay between the ends of the coasting shading device 22 . 122 cause. The touch of the engagement projections 25a against the engagement recesses 24a could also possibly generate noise.

In an in 38 Therefore, modification shown are an engagement surface of each engagement recess 24a and an engagement surface of each engagement projection 25a arcuately curved instead of the right-angled shapes. Each engagement recess 24a and the corresponding engagement projection 25a are always in contact with each other. Especially if the connection 24 and the central rod 25 are aligned linearly in the axial direction, are the curved engagement surface of the engagement recess 24a and the curved engagement surface of the engagement projection 25a together at two points (points P in 38 ) engaged. Will the central rod 25 relative to the connection 24 pivoted upward in the Y direction, so are the engagement recess 24a and the engaging projection 25a at two points (points Q in 38 ) engaged. Will the central rod 25 relative to the connection 24 pivoted in the direction perpendicular to the Y direction, so are the engagement recess 24a and the engaging projection 25a engaged at two points (not shown). The coasting shading device rotates 22 . 122 in 37 , so get the engagement recess 24a and the engaging projection 25a repeated in line contact and then in point contact between them.

As above with respect to 38 was discussed, are the engagement recess 24a and the engaging projection 25a always engaged with each other when the central rod 25 linear to the connection 24 is aligned or if the central rod 25 relative to the connection 24 is pivoted in, for example, the Y direction. The torque of the central rod 25 is therefore without a significant rotation delay directly on the connection 24 transferred when the central rod 25 is rotated about its axis. The torque is also directly to the next central rod 25 transmit, which with the other end of the connection 24 engaged. A rotational delay can thus be substantially between the ends of the coasting shading device 22 . 122 be prevented.

The engagement recess 24a and the engaging projection 25a Further, by means of the contact of curved surface with a curved surface in engagement. When turning the roll-out shade direction 22 . 122 Thus, the resistance and the noise can be reduced, whereby a smooth rotational movement of the coasting shading device 22 . 122 is possible. In case of 38 stand the engagement recess 24a and the engaging projection 25a further engaged with each other by curved surfaces to even when pivoting the central rod 25 relative to the connection 24 to have contact of curved surfaces in the Y direction. The pivoting movement of the central rod 25 relative to the connection 24 is thus compared with the one in 37 gentler case. The entire rotational movement of the roll-out shading device 22 . 122 is therefore as a result compared with in 37 softened case.

In the modification of 38 are the engagement recess 24a and the engaging projection 25 As discussed above, curved to the engagement between the engagement recess 24a and the engaging projection 25a regardless of the curvature of the roll-out shade device 22 . 122 to maintain. It is thus not necessary to increase the size of the space A based on the curvature of the coasting shading device 22 . 122 increase.

Are the engagement recess 24a and the engaging projection 25a made rectangular, the size of the space A must be based on the curvature of the roll-out shading device 22 . 122 be fixed. The number of connections 24 and the central rods 25 thus adversely affects. Are the engagement recess 24a and the engaging projection 25a however curved arcuately, so can the engagement recess 24a and the engaging projection 25a regardless of the curvature of the roll-out shade device 22 . 122 each having constant shapes. The number of types or types of connections 24 and the central rods 25 is therefore not increased.

The connection 24 and the central rod 25 can also be found in an in 41 be modified manner shown. This means that each engagement recess 24a and the associated engagement projection 25a are curved such that a narrowed portion, ie a neck, in a base of each engagement recess 24a and interventional advantage 25a is configured while its distal end is widened.

In the modification of 41 is a distal end of the engagement projection 25a curved substantially arcuately to represent the widest portion, and the base of the engagement projection 25a is compared with the distal end of the engagement projection 25a designed narrower. The engagement recess 24a is slightly larger than the engagement projection 25a and homothetic to the engagement projection 25a , The narrowest section of the engagement recess 24a is narrower than the arcuately curved end of the engagement portion 25a , In the engaged state of 41 may be the distal end of the engaging portion 25a thus not by the narrowest portion of Eingriffsausspa tion 24a migrate through. At the in 41 shown state, the engagement between the connection 24 and the central rod 25 therefore not be solved when the connection 24 and the central rod 25 be pulled away from each other to the connection between the connection 24 and the central rod 25 lift off, as the axial relative movement between the connection 24 and the central rod 25 is limited. The state of engagement between the connection 24 and the central rod 25 is thus maintained effectively and reliably.

Similar in the 38 shown modification are in 41 shown engagement projection 25a and the engagement recess 24a curved and always engaged. Are the connection 24 and the central rod 25 aligned linearly in the axial direction, so are the engagement recess 24a and the engaging projection 25a at two points (points P in 41 ) in conjunction with each other. Will the central rod 25 relative to the connection 24 pivoted upward in the Y direction, so are the engagement recess 24a and the engaging projection 25a at two points (points Q in 41 ) with each other. Will the central rod 25 turned, so the rotational force of the central rod 25 Thus, without significant rotation delay directly on the connection 24 transfer. In this way, a rotational delay between the ends of the coasting shading device 22 . 122 be substantially eliminated. The engagement recess 24a and the engaging projection 25a may also be in contact with each other by the contact of a curved surface with a curved surface. When rotating or rolling the Ausroll-shading device 22 . 122 Thus, the resistance and the noise can be reduced, whereby a soft rotational movement of the coasting shading device 22 . 122 is possible.

The roll-out shade device 22 . 122 The first and second embodiments may further be incorporated in one of 41A to 43 be shown kind modified. In the 42A to 43 are the rotatable rod 22d the coasting shading device 22 . 122 by connecting central rods 425 through connections 424 configured, each of which has a bellows.

43 shows a state in which the central rods 425 by means of the connections 424 connected and bent. 42A shows a perspective view of one of the compounds 424 , In this modification, every central pole has 425 a predetermined rigidity, wherein a rigid material, such as synthetic resin or metal, for configuring the central rod 425 is used. Every connection 424 is designed like a flexible connection. Cylindrical connections are respectively at opposite ends of the connection 424 designed. The cylindrical compounds of the compound 424 are by means of a bellows 424a connected. Bone 424b and hollows 424c are alternately in the bellows in the axial direction 424a arranged. The shape and the material of the burrs 424b and the hollows 424c are selected to allow bending in the axial direction. The bellows 424a is thus expandable in the axial direction and may be configured as a metal leaf spring arrangement. The connection 424 can work this way in an in 42B be bent as shown. To a quantitative difference of the wound shielding 21 . 121 between the ends of the rotatable rod 22d when winding the shielding 21 . 121 to restrict, the bellows has 424a a predetermined torsional stiffness, which is the twisting of the bellows 424a , which by the torque, which of the spiral spring 22b is applied around the axis of rotation arises, limited.

The ends of the connection 424 are each at the adjacent central bars 425 attached. A known screw device or threaded device, which is commonly used for flexible connection, can be used as a securing device for connecting the connection 424 with the central rods 425 be used. It also does not require the connection 424 completely at the corresponding central bars 425 to fix. Moreover, the securing device is only required to allow relative movement between the connection 424 and the central rod 425 to avoid around the rotation axis. In the above design, the rotatable rod 22d whose central rods 425 through the connections 424 are adapted to match the curved shape of the central axis 22a match. The rotatable rod 22d can thus be relative to the central axis 22a turn gently.

The in the 22a to 43 The modification discussed above can also be applied to the in 44 be modified manner shown. In 44 is in place of the bellows 424a which is between the corresponding two central rods 425 is arranged, an elongated element winds around a coil element 424d to build. A round-section metallic cable is rolled flat into a substantially flat, elongate member by a metal rolling process, and this elongated member is helically wound into a coil. The helically wound coil element 424d can be elongated axially elastic in this design. Like the bellows 424a can the coil element 424d ie the connection 424 to be bent in any circumferential direction. At the coil element 424d becomes a peripheral surface of the coil element 424d radially retracted or extended when one end of the coil element 424d is turned. For example, if a limiting element, which such a radial retraction or extension of the peripheral surface of the coil element 424d limited, provided, so may be a twist or rotation of the coil element 424d upon application of a rotational force to the coil element 424d be limited.

In the connection described above 424 it is possible to provide a plurality of layers of bellows or coils, which are arranged one above the other in the radial direction. In this design, a desired torsional rigidity, which is not achieved with the individual layer of the bellows or coil, can be achieved. In the case of coils to make the connection 424 can be used, two coils, which are wound relative to each other in the opposite direction, be superimposed in the radial direction. In this configuration, a diameter of one of the two coils is reduced when a rotational force is applied to one end of the superposed coils, with a diameter of the other of the two coils increasing. The relative displacement of the superposed coils is thus limited, and deformation of the superposed coils is also limited. The connection 424 In this way, there is no delay section, which causes a significant rotational delay in rotation or rotation of the connection 424 shows. The bellows and the spool can be further combined with each other in the design of the compound.

The connection 424 may also be made of a wound tape element, such as a vinyl tape. In such case, a core material may be provided which retains its shape or allows only slight deformation, and the band member may be wound around the core material. The wound tape element may alternatively be alone between the ends of the connection 424 to be ordered. The connection 424 can be configured as a flexible element in this way.

In the in the 43 and 44 The modifications shown are the short central rods 424 each of which has a comparatively short axial length, connected together, and each flexible connection 424 is in the appropriate connection between the adjacent central rods 425 arranged. However, it should be appreciated that the construction of the in 26 gezeig modification or modification to the 43 and 44 shown modifications can be applied. The comparatively short central rods 425 and the comparatively long central rods 425 may be interconnected based on the corresponding curvature such that the number of components of the rotatable rod 22d can be reduced and easily to the curvature of the central rod 22a can be adapted. To the function of each connection 424 as a joint to facilitate, is the axial length of each compound 424 shortened and uniformly designed. However, the present invention is not limited to this embodiment. For example, based on the curvature, different types or types of compounds 424 , which each have different axial lengths can be used.

Instead of the bellows and the coil only in the compound as in the 43 and 44 provided modifications, may be a predetermined longitudinal portion of the rotatable rod 22d be made of a bellows or a coil. In case of 36 For example, the regions R2, R3, R4 may be configured as an elongated element made entirely of one or more bellows or a coil. The entire rotatable rod 22d may also be made of one or more bellows or one or more coils. If the elongated member is to be made of the one or more bellows or coil (s), such bellows or coils should have a required torsional stiffness required to transmit a required torque and also have a required flexural rigidity, which is required to maintain its curved shape.

The rotatable rod 22d can be modified in the following way, with which adjacent central rods 525 by means of connecting pins 524 connected to each other.

45A With reference to this modification, it shows a cross-section of the connection between the adjacent central rods 525 , and 45B shows a cross section along the line XLVB-XLVB 45A , As in the 45A and 45B shown has each cylindrical central rod 525 at its respective longitudinal end a plurality of guide holes or openings 525a , One end of each connector pin 524 is in a corresponding leadership hole 525a inserted so that about half of the guide pin 524 in the leadership hole 525a slidably received.

The guide holes 525a one of the opposite ends of the adjacent central rods 525 lie the leadership holes 525a the other of the opposite ends of the adjacent guide rods 525 axially opposite. An end to every leader 524 is in the appropriate leadership hole 525a the other of the opposite ends of the adjacent central rods 525 inserted and secured, and the other end of each connecting pin 524 is displaceable in the corresponding guide hole 525a the other of the opposite ends of the adjacent central bars 525 added. Every guide pin 524 is made of a flexible material such as a cable material, which in the bending direction of the rotatable rod 22d is flexible.

The neighboring central bars 525 are in this design by means of the connecting pins 524 connected such that a relative movement between the adjacent central rods 525 in the longitudinal direction is possible. Because every connecting pin 524 flexible in the bending direction, the connecting pin 524 bent in the bending direction, as in 45C is shown. The neighboring central bars 525 are in this way by means of the connecting pins 524 flexibly connected. If every connecting pin 524 is configured to bend in the bending direction in the manner described above, so the rotatable rod 22d be bent or curved. A relative movement between the adjacent central rods 525 is by means of the shear strength of the connecting pins 524 limited. In the case of the rotatable rod, which by connecting the central rods 525 is configured, the rotatable rod can thus follow the curved shape of the central axis and be rotated integrally about its axis.

Instead of the flexible connecting pins 524 Further, a cushioning material may be provided in an inner peripheral wall surface of each guide hole 525a be provided. Is the cushioning material in the inner peripheral wall surface of each corresponding guide hole 525a provided, the cushioning material by a pressing force of the connecting pin 524 be bent or deformed to a bending of the rotatable rod 22d to enable. The cushioning material is desirably only in a radial direction of the guide hole 525a instead of being arranged in a circumferential direction. In this structure, each connecting pin presses on a corresponding surface, which is made of a non-flexible material when the pressing force on the central rod 525 around or over the axis of the central rod 525 is applied. The torque is thus transmitted directly between the neigh th central rods. As a result, the positional shift between the opposite ends of the rotatable rod can be made at the time of winding up or unwinding the screening web 21 . 121 essentially prevented or eliminated.

In the embodiment shown above, the coasting shading device 22 . 122 the central axis 22a on, with the cylindrical rotatable rod 22d around the central axis 22a is arranged around the central axis 22a cover or cover. However, the present invention is not limited thereto. In an alternative roll-out shade device 622 as they are in 46 is shown, for example, on the central axis 22a dispensed with, and a plurality of axle bodies 625 are connected by joints, each of which can be bent and a rotational force about or about an axis of the rolling-shade device 622 can transfer.

At the in 46 shown Ausroll-shading device 622 is the multitude of axle bodies 625 connected together to form an elongated element. Each of the opposite ends of the roll-out shade device 622 is also with one end of a corresponding or corresponding side bar 623 connected. A base end of the shielding membrane 21 is with the roll-out shading device 622 connected.

In this modification, the central axis is not provided. The side bars 623 connected to the opposite ends of the roll-out shading device 622 are respectively rotatable from the rolling-shading holders 26 carried. One end of a spiral spring 622b is in this case with one of the roll-out shade holders 26 connected, and the other end of the coil spring 622b is at the opposite end of the roll-out shading device 622 connected. The roll-out shade device 622 can thus by the coil spring 622b receive or record a torque. One end of the adjacent side bar 622 on the side of the roll-out shade holder 26 , which is the spiral spring 622b is adjacent, is designed as a hollow end, and the coil spring 622b is in the hollow end of the side bar 623 arranged.

The connections 624 each of which is between two corresponding, adjacent axle bodies 625 This modification will be described next. Every axle body 625 is designed as a substantially cylindrical body. Every connection 624 also has axle support sections 624a . 624b and a rotatable element 624c on. The rotatable element 624c has two axes which are perpendicular to each other. Opposite ends of one of the two axes of the rotatable element 624c are rotatable with the axle support portion 624a connected, and opposite ends of the other of the two axes of the rotatable member 624c are rotatable with the axle support portion 624b connected. Each of the axle support sections 624a . 624b is at one end of the corresponding axis element 625 secured or secured.

In this apparatus, each of the axle support portions is 624a . 624b around a corresponding one of the two axes of the rotatable element 624c rotatable, which are perpendicular to each other. The axle body 625 , which in each case with the axis support sections 624a . 624b can be relative to each other about the rotatable element 624c to bend. None of the axle bodies 625 also rotates relative to the adjacent axle body 625 around his axis. That means that the connection 624 which the axle support sections 624a . 624b and the rotatable element 624c has, forms a universal connection.

The universal bond, which is the connection between the adjacent axle body 625 is not limited to the above design. The universal joint may be, for example, a ball joint in which a spherical rotatable member slidably contacts a spherical inner surface of the corresponding axle support portion. In this modification, each axle body has 625 Further, a predetermined stiffness and may be made of a rigid material such as synthetic resin or metal.

The roll-out shade device 622 is configured in this embodiment, in order to connect to corresponding 624 to bend so that the coasting-shading device 622 in conformity with the shape of the edge of the disc W can be curved. The relative rotation between the adjacent axle bodies 625 around the axis is also limited. The connected axle bodies 625 can thus rotate in one piece or integral. The roll-out shade device 622 can the shielding 21 thus softly unwinding or unwinding without creating a deceleration section which causes a substantial rotational delay in the rotation of the coasting shading device 622 shows.

In this modification, similar to the above modifications based on the corresponding curvature of the disc W comparatively short axle 625 and comparatively long axle body 625 may be suitably used in combination so that the number of components of the roll-out shade device can be reduced, and the roll-shade device is easy to bend the disc W are adjusted. In a region in which the curvature of the disk W is comparatively small, in particular the relatively long axle body can 625 be used. In a region in which the curvature of the disc W is relatively large, furthermore, the relatively short axle body can 625 be used.

The following configuration may be used instead of the universal connection if the central axis is omitted or omitted. For example, one end of an elastic element such as a rubber element or a spiral spring with a predetermined torsional or rotational stiffness can not be rotated at the corresponding end of the axle body 625 be attached, and the other end of the elastic member can not rotate on the adjacent end of the next axle body 625 be attached. The roll-out shade device 622 can be bent in this construction or this design and transmit the torque.

The roll-out shade device 622 As a result, the winding or unwinding of the Abschirmbahn 21 . 121 turn in one piece.

The drive device 110 is in the second embodiment between the door panel 104 and the door panel 102 arranged. However, the present invention is not limited thereto. One end of the roll-out shade device 122 for example, may be hollow, and the drive device 110 can be in the hollow end of the roll-out shading device 122 be recorded. In the second embodiment, the roller 133 for example, be located at a suitable location to the cable 132 along the back frame 103c behind the lower end of the guide rail 131 to extend when the drive device 110 in the rear end of the roll-out shading device 122 is arranged, and the cable can be deflected by means of a roller or a plurality of rollers to pull the sliding piece 135 to allow in one direction down. As a further alternative, the drive device 110 in the front end of the roll-out shading device 122 be arranged.

The drive device 110 and the guiding device 130 may be integrally formed as a module in the second embodiment. In this way, the device or the installation of the drive device 110 and the guide device 130 be simplified in the door advantageous. The roll-out shade mechanism 120 can also be integral with the drive device 110 and the guide device 130 be designed as a module.

The sliding piece 135 is in the second embodiment in the free end of the Abschirmbahn 121 provided such that the sliding piece 135 along the corresponding guide rail 131 guided in the vertical direction to the Abschirmbahn 121 drive out and retract. However, the present invention is not limited thereto. For example, a cable may be directly to the right side of the free end of the screen 121 be connected, and the cable can be wound from the drive device to a corresponding coil to the Abschirmbahn 121 to move in a vertical direction.

In the 28 The device shown can also in the in the 47 and 48 be changed device shown. The shielding 121 of the 47 and 48 is stretchable and with a web-side engaging portion 121 Mistake. The web-side engagement section 121 this modification is along the lateral side of the Abschirmbahn 121 provided, which along the rear frame 103c is arranged. In this modification, the web-side engaging portion 121 intermittently along the lateral side of the Abschirmbahn 121 be provided.

Similar to the modification of the first embodiment, in this case, a guide member 107 and a guide element 108 opposite each other along the slot 105a between the mount 105 and the rear frame 103c at the rear end side of the window glass 106 intended. A guide groove 107a is in the guide element 107 configured to engage with the web-side engaging portion 121 to be engaged. If the shielding 121 is extended or retracted, then the web-side engagement section 121 between the guide element 107 and the guide element 108 held and guided in the vertical direction, wherein the movement of the web-side engaging portion 121 in the direction of the width of the shielding 121 by means of the guide groove 107a is limited or limited.

In 47 is the web-side engagement section 121 in the outer surface of the Abschirmbahn 121 designed, which is directed to the outside of the vehicle. However, the present invention is not limited thereto. For example, the web-side engagement section 121 on the inner surface of the Abschirmbahn 121 , which faces the interior of the passenger compartment, may be provided, or it may on the outer surface and the inner surface of the Abschirmbahn 121 be provided. The corresponding guide element or the corresponding guide elements 107 which the guide groove 107a for engagement with the web-side engagement portion or the web-side engagement portions 121 should, in such a case be provided.

In case of 47 is the cross section of the web-side engaging portion 121 of semi-circular shape. However, the present invention is not limited thereto. For example, the cross section of the web-side engaging portion 121 a rectangular cross section or a triangular cross section, as in the 25a 25c are shown have.

Further modifications, which shrink or shrink the Abschirmbahn in the direction of the width of the Abschirmbahn 121 limited upon extension of the Abschirmbahn to cover substantially the entire window, with respect to the 49 to 59 described.

The The following modifications will be made with reference to the windscreen W the first embodiment described. However, it should be understood that these modifications also on the rear window or the side window of the second embodiment are applicable.

One of the modifications will be next with reference to the 49 to 51 described. In this modification, a plurality of protruding bodies (web-side engaging portions) 61 along each of the lateral sides of the screen 21 arranged. The protruding bodies, which on each side of the Abschirmbahn 21 are arranged are of a corresponding or associated guide rail (a vehicle-side engaging portion) 51 carried.

In the present modification, the guide rails 51 which is used to maintain the shape of the Abschirmbahn 21 be used, parallel to the guide rails 31a . 31b arranged, which are used to move the pieces 35 slidably lead. Every guide rail 51 is essentially the same length as any guide rail 31 ; 31b , so that upper and lower ends of the guide rail 51 are arranged at substantially the same heights as those of the guide rail 31a . 31b , Every guide rail 51 Can be integral with the corresponding guide rail 31a . 31b be designed, this should be desired.

In the present modification, an extension extends 35c , as in 49 shown by the shaft connecting portion 35b each sliding piece 35 in a direction perpendicular to the extension direction of the Abschirmbahn 21 , A distal end of the extension 35c each sliding piece 35 is with a corresponding portion of the free end of the Abschirmbahn 21 connected, which at a small distance to the corresponding lateral side of the free end of the Abschirmbahn 21 towards the middle of the width of the Abschirmbahn 21 is spaced.

In the in 49 shown modification is the Abschirmbahn 21 with the moving pieces 35 connected. However, the present invention is not limited thereto. So can the shielding 21 for example, alternatively with the push rods 28 be connected.

Every guide rail 31 is an element with a substantially U-shaped cross-section. Every guide rail 51 also has a sliding room 51b in which the protruding bodies 61 in the guide rail 51 be moved. Every guide rail 51 also has a slot 51a , which on a passenger compartment side of the guide rail 51 is provided and with the sliding room 51b communicated.

The protruding bodies 61 are at predetermined intervals along the corresponding lateral side of the screen 21 arranged such that the projecting body 61 essentially with the entire length of the corresponding guide rail 51 engage when the shielding 21 is brought into the fully extended position or is. Because the protruding body 61 along the corresponding lateral side of the Abschirmbahn 21 spaced apart, retains the entire Abschirmbahn 21 the flexibility in order to wind up or

Rolling up the shielding membrane 21 around the roll-out shade device 22 to enable.

Every prominent body 61 is configured as a rectangular body and has a groove on one side of the protruding body 61 , The corresponding lateral side of the screening 21 is in the groove of every protruding body 61 inserted and by means of the above body 61 securely trapped.

Each connecting body 67 has a rail-side sliding portion 67a and a web-side sliding portion 67b on. The railside section 67a slides along the guide section 57a and the web-side sliding portion 67b supports or supports the rail-side sliding portion 67a to the corresponding lateral side of the Abschirmbahn 21 , Each adjacent two rail-side sliding portions 67a are by means of a corresponding connecting element 67c connected with each other.

A flexible, linear rail element 21b is with each lateral side of the Abschirmbahn 21 connected. The web-side sliding section 67b of each associated connector body 67 is displaceable on the corresponding rail element 21b attached. The web-side sliding section 67b of the lowest connection body 67 , which is the free end of the shielding 21 is closest, is not displaceable on the rail element 21b attached. The rail element 21b is so flexible that the rail element 21b together with the shielding 21 around the roll-out shade device 22 can be wound.

Each connecting element 67c represents the connection between two corresponding adjacent connecting bodies 67 such that a separation and a contact of the corresponding two connecting bodies 67 in the extension direction of the Abschirmbahn 21 is possible. In the present modification, a cable is used as a connecting element 67c used. Opposite ends of the connecting element 67c are each with the web-side sliding sections 67b the corresponding two connecting bodies 67 connected. When retracting or retracting the shielding 21 does not disturb a connecting element 67c the advancing movement of the corresponding two connecting bodies 67 toward each other until the connecting bodies 67 engage each other. When extending the shielding 61 limits each connection element 67c but a space between the corresponding two connecting bodies 67 when the connecting element 67c fully extended constantly. In the present modification, the connecting elements have 67c when moving the Abschirmbahn in the shadow position depending on the elongation of the Abschirmbahn 21 in the direction of latitude different lengths. The length of the connecting element 67c showing the connection between the connecting bodies 67 which produces at the free ends of the Abschirmbahn 21 are arranged is less than the length of the connecting element 67c showing the connection between the connecting bodies 67 which is on that of the roll-out shading device 22 facing side of the shielding 21 are arranged.

Will the shielding 21 spent in the present modification in the fully retracted position, so are the connecting body 67 at the upper end side of the guide rail 57 arranged close to each other or lined up. Will the drive device 10 pressed to the shielding 21 From the fully retracted position to extend to the fully extended position, so is the lowest or lowest connection body 67 , which on the rail element 21b is attached and the free end of the shielding 21 is closest, by means of the shielding 21 pulled and thus along the guide rail 57 moved down. The other connecting bodies 67 stay on the guide rail for a while 57 at rest, and the web-side sliding sections 67b the other connecting body 67 slide along the rail element 21b ,

When the lowest connection body 67 is shifted downwards by a predetermined distance, then the connecting element 67c , which with the lowest connection body 67 connected, fully extended. The second lowest connection element 67 , which is the lowest connection body 67 at the upper end side of the Abschirmbahn 21 is closest, is therefore by means of the connecting element 67c , which at the bottom connecting body 67 is attached, pulled down. The other connecting bodies 67 are pulled down sequentially in this way.

Will the shielding 21 extended in the manner described above, so are the connecting body 67 pulled apart to substantially with the entire guide rail 55 to engage in the shadow position, as in 57 is shown. When extending the shielding 21 become the connecting bodies 67 , which on the lateral side of the Abschirmbahn 21 are attached, along the guide rail 57 postponed. Due to the engagement between the connecting bodies 67 and the corresponding guide rail 57 may be a warping or a contraction of the Abschirmbahn 21 be advantageously limited in the direction of the width. As in 57 is shown, therefore, the entire area of the disc W can be substantially covered when the Abschirmbahn 21 is in the shadow position.
