Abstract

The sunshield roller has an uncoiled base web (2), and rollable side components (3A,3B) which are laterally arranged at the base web. The side components are vertically extended to the rolling direction of the base web. The side components have triangular form.

Description

The The present invention relates to a sun blind for covering a sun blind Automotive windshield, in particular a panoramic window, with a unrollable base course.

Generic sunblinds with a rollable from a winding shaft base to cover a motor vehicle windshield are for example from the DE 20 2006 011 455 U1 known.

From the US 6,227,601 B1 For example, a lamellar sunshield is known for a trapezoidal windshield, the rigid, multi-part vanes of which extend transversely to cover different width regions of the trapezoidal windshield.

The DE 103 60 629 A1 proposes to cover a panoramic window, ie a windshield, which continues in a roof window of the motor vehicle, also a sun cover with stiff, articulated lamellae, wherein laterally hinged to a lamellae for the trapezoidal windshield area hinged rigid side parts. However, such a cover can not be rolled up on a winding shaft.

From the DE 20 2006 011 452 U1 a sunblind is known for covering a rear window with an unrollable base web. To cover the trapezoidal disk, the base web is trapezoidal cut. In particular, when panoramic windows are to be covered with rectangular roof window areas and trapezoidal windshield areas, the blank, the positioning accuracy and the winding pattern of such base webs, which are cut and rolled according to the contour of the disc to be covered, would cause problems. Accordingly, the winding shaft in the DE 20 2006 011 452 U1 arranged on a bottom rear window, so that the trapezoidal base web is rolled with its longer edge first.

If a drawbar connected to the basic web is displaced by carriages in lateral guide rails next to a trapezoidal disk, the DE 20 2006 011 U1 , the DE 197 45 866 C1 and the DE 20 2005 011 290 U1 to articulate the towing bar on the variable pitch carriages by sliding in and out of the carriage carriages in recesses in the pull bar or cantilever of the pull bar in recesses in the carriage. However, this is in particular not suitable for guide rails, if their distance does not vary monotonously, as in panoramic windows in which the guide rails partially, in particular in a roof window area, a constant distance and partially, in particular in a trapezoidal windshield area, a variable distance from each other.

task It is the object of the present invention to provide an improved sun blind to provide that at least one of the drawback reduces or avoids the known sunblinds.

These The object is solved by the features of claim 1 and 7, respectively. Advantageous embodiments of the invention are the subject the dependent claims.

To A first aspect of the present invention comprises a sun blind for covering a motor vehicle windshield, in particular a panoramic screen, an unrollable base course.

The base web may in particular have a substantially rectangular section, which facilitates its cutting and the winding or unwinding on a winding shaft. It may preferably be made of textile material or plastic and is preferably so flexible that, preferably tightly, it can be rolled up or wound onto a winding shaft and thus takes up little storage space when rolled up. Their opacity may preferably be at least 50%, preferably at least 75% and in particular substantially 100%, wherein the luminous opacity is, for example, the quotient of the luminous intensity, measured, for example, in Candela [cd], a luminance measured, for example, in [cd / m ² ], a luminous flux, measured, for example, in lumens, a quantity of light, measured, for example, in lux, behind the shade divided by the appropriate size before the shade can be defined.

According to the invention the sun blind at least one rollable arranged laterally on the base web Side part, which is perpendicular to a direction of unwinding the base web is extendable. Preferably, the base web is ever at least on both sides provided such a side part.

By such side parts now areas of the windshield can be covered, which are not covered by the particular rectangular base web when it is unrolled. This is particularly advantageous when the sun blind is parked completely shaded a panoramic roof with a preferably rectangular roof window area and a substantially trapezoidal windshield area, for example. On the other hand, rolling side panels can be used together with the Basic web rolled up on the winding shaft and be stowed so as not to save space.

One Side part has in a preferred embodiment in the Essentially triangular, sail-like shape on, in particular along with a substantially rectangular base course one Cover trapezoidal disc area. Depending on the shape the disc to be covered may have base web and / or side panels also have other shapes, which are preferably such that by the base track and the extended side panels essentially the Slice is covered.

One or several side parts can be made of the same material be made as the basic train, or even from another Material which, for example, another wall thickness, Stiffness, opacity, color or the like can have.

Preferably is a side part with a certain overhang or a certain coverage over, d. H. closer to the disk to be covered, inside or below the base web, d. H. closer to the passenger compartment, arranged so that too with the side panel pulled out no gap between it and the base web occurs.

Around a side part perpendicular to an unwinding direction of the base web take off, it may on the one hand be elastic, so that it under elastic deformation, in particular elongation, its surface enlarge and released from the base track Cover areas of the disc. Additionally or alternatively a side part can also be elastic, for example by means of a stretchable hinge to be connected to the base web. Both possible on the one hand a length compensation in the extension direction and rolling up together with the basic train. In a preferred embodiment is the material of a side part and / or a hinge in Transverse and longitudinal elastic, for example as a fiber material executed.

additionally or alternatively, in particular inelastic side part, can this in a rotary bearing and / or in a train or longitudinal stock hinged to the base railway, d. H. be articulated with this. For example, a rear in unwinding or unwinding direction a triangular side part in a pivot bearing on the base web be hinged, while its in the unwinding front edge is guided in a longitudinal bearing. Preferably Pivot bearings and / or tension bearings by elastic portions of the base web and / or the side part, in particular by elastomers, formed, the high mobility, low production costs and cause a restoring force in a relaxed position can.

Further additionally or alternatively, again in particular inelastic Seitenteil, this can be a folding, in the form of an accordion or a bellows, so that the side part by at least partial unfolding perpendicular to the unwinding direction of the base web is extendable. The folding can be perpendicular to the direction of unwinding or be inclined towards this. In this context, let pointed out that an inventive Take off perpendicular to the unwinding direction of the base web only also requires a component of motion perpendicular to the direction of unwinding, but can also include movements with other components. Thus, in particular, a side part, which is a pivot bearing is pivoted relative to the basic trajectory, (also) perpendicular to the Enttrollrichtung pulled out because the tangential vector of the movement on a circular path around the pivot bearing also has a component perpendicular to the direction of unwinding.

In a preferred embodiment, a side part is elastic biased toward the base web, for example, by the side part, a stretchable hinge, a rotary or a tension bearing designed to be elastic is. Thus, the side panel when not in use by the elastic Preloaded and can be rolled up better together with the base web become.

Around the side part, in particular against a resilient bias, Extend it perpendicular to the unwinding direction, it is in a preferred Embodiment articulated on a carriage of a guide, for example in a rotary bearing or via an elastic connecting link, in particular an elastic band. Will the carriage to roll out the base web to a front or lower edge of the covered Shifted disc, he draws while the side part connected to him perpendicular to the unwinding direction, when the carriage and the base web side edge remove each other, d. H. a gap between the example rectangular base track and the example trapezoidal windshield area arises.

It is also initially the base web in a predetermined position, in particular a windshield completely covering position extended to shadow the interior and then one or more side panels are pulled out. Accordingly, one or more side parts can first be pulled in or pushed in towards the base web before it is rolled up. For such a sequential extension or retraction movement of the base web and the side part, a separate drive for one or more side parts may be provided which pulls or retracts it, for example via cables or the like, after the base web has been pulled out or before the base line is retracted. Likewise, the side part can also be coupled accordingly to the drive of the base web.

To a second aspect of the present invention, which is identical to the above However, the first aspect discussed may be combined also independently is advantageous, has a sun blind for covering a motor vehicle windshield, in particular a panorama window, next to an unrollable basic train a guide, arranged in the form of laterally adjacent to the disc to be covered Guide rails and slidable carriage, as well one guided in this guide and with the Basic train connected to drawbar.

According to the first aspect can be arranged on the base web side panels be pulled out, for example, by the sled, if the sun blind is unrolled. Alternatively, the base can also continuously, d. H. formed in one piece without extendable side parts be and for this purpose, for example, essentially in the form of covering Slice be cut, so about a trapezoidal Section for covering a trapezoidal windshield area, preferably in addition a rectangular Section for covering a rectangular roof window area, exhibit.

According to the invention the pull bar on at least one slide of the guide not only with variable distance, but above also articulated angularly movable. Not only can not a constantly increasing distance between Guide rails, approximately along a trapezoidal Windshield area, but also varying gradients the leadership, about a transition to a rectangular Roof window area with parallel guide rails to be displayed.

A angularly movable articulation can be realized, for example be that the pull bar with a slide of the guide connected in a swivel joint. Additionally or alternatively the Zugspriegel also by means of a boom with a carriage be connected to the leadership that is elastic and so on Having angular mobility. The boom can also, for example conical or sickle-shaped, curved and so a change allow the angle between the towing hitch and the slide, which is referred to herein as angular mobility. The boom can also be performed with angular play in a recess, so that it can be rotated in the recess by a certain angle is by the recess correspondingly larger Has dimensions or a corresponding shape.

In a preferred embodiment, the guide two lateral guide rails on which carriages, preferably parallel, are displaceable by the same drive. The common drive, for example, the slide over Tension or compression cables, gears, a cable, hydraulic and / or move pneumatically.

Around to center the roller blind during rolling up or down, the towing bow is elastic in a preferred embodiment tied to one or both sleds of leadership. For this can, for example, between the two carriages or several elastomers, which are the hollow drawbar and are connected to it. additionally or alternatively, the pull bar can be attached to one or both carriages the front side, about feathers, be tied up.

Especially, if the drive is electrically controllable, one, preferably Changeable, track limitation for one or be provided several slides of leadership. Such Track limitation, for example, can prevent the sunblind while driving too far, especially in a the windshield completely covering shutoff position, unrolling and so the driver's view impaired.

For this For example, one or more mechanical or be provided control technology attacks, the or the attacks in a preferred embodiment are changeable. A stop that pulls the blind over A driving position also prevents the driver from driving forward Glare is protected by low sun, but sufficient View to the front can, for example retracted or moved be when the vehicle is stationary and the shade for shading the Interior to the lower edge of the windshield may be pulled out.

A Such Fahrwegbegrenzung can, especially in electrically controllable Drive, also be achieved by the position or the track the blinds by a displacement sensor or a sensor, such as an electric Switch, induction sensor, Hall sender or photosensor detected and a movement depending on the detected position of the roller blind, in particular a further extension or unrolling or unrolling, is prevented.

Preferably is a track limit depending on a central locking, an ignition or the like changeable. Consequently can, for example, with activated ignition of the track on a not completely covering the windshield area Position be limited.

Around the at least partially extended sun blind against sagging to support in the vehicle interior, are according to a preferred Execution of one or more sliding crossbeams provided for supporting the base web. these can For example, in guide rails, in which also the drawbar is guided, or in separate guide rails be slidably guided. They are preferably independent displaceable by the Zugspriegel and particularly preferably either releasably coupled with this, for example via Hooks or magnets, or via a drive, for example by means of tension, compression cable, cable, gear drive, hydraulic or pneumatically movable.

In In a preferred embodiment, the length is at least a preferably multi-part cross bow changeable. Additionally or alternatively, a crossbeam can be displaced be led on a sled to a variable Offset the distance between guide rails.

1 shows a sunroof according to a first aspect of the present invention in plan view. To cover a panorama windshield 1' with a rectangular roof window area (top in 1 ) and a trapezoidal windshield area contiguous thereto (bottom in FIG 1 ), the sunblind has an unrollable rectangular textile base web 2 on that on a winding shaft 6 on or from this unwinding or -rollbar. The winding can, for example, manually, spring loaded, for example under a torsion spring that is stretched when rolling, or motor, such as by an electric motor, the unwinding of the sun blinds also manually or by motorized method of carriages in side guide rails, the sun blind in Unwinding direction is connected at the front with the carriage.

Both sides of the basic train 2 are triangular side parts 3A . 3B arranged. They are each a swivel joint 4 , which is formed by an elastomer, with their in the direction of unwinding (from top to bottom in 1 ) rear tip hinged to the base track, allowing it to pivot around the pivot 4 under the basic train 2 can be swung out so as to cover the lower, wider portion of the trapezoidal windshield area when the sun shade is completely unrolled for shading the parked vehicle.

To this extraction movement perpendicular to the direction of unwinding the base web 2 to lead and the pulled-out side panels 3A . 3B rolling in the basic train 2 Swinging under this again is the lower corner of each side part in the unwinding direction 3A . 3B , which is the basic train 2 facing, at this means of a train or longitudinal bearing 5 hinged, which is also formed by an elastomer, which extends when pulling the side part 3A respectively. 3B perpendicular to the unwinding direction of the base web 2 stressed.

Thus, the movable triangular sail serves 3A . 3B on each main track side, the otherwise uncovered areas in the windshield 1' to cover evenly.

To describe the sails 3A . 3B with certain overhangs roughly the area, resulting in a rectangular unrolled base course 2 in the windshield 1' conditioned by their trapezoidal design on both sides.

Sail 3A . 3B are movable in parallel under the base line 2 positioned to wind up the base web 2 together with the sails 3A . 3B on the winding shaft 6 to enable.

The lower corner of each side part in the direction of unwinding 3A . 3B which of the basic train 2 is facing away, is connected via a rotatable bearing point with a carriage which is motorized or manually displaceable in the guide rail in the roof or A-pillar beam (not shown).

In a modification, not shown, these lower corners, for example via cables, connected to their own drives, which are controlled so that the sail 3A . 3B be taken off only when the basic train 2 fully extended, and to the base course 2 be retracted before the base train 2 being rolled up.

2A . 2 B show a sunroof according to a second aspect of the present invention for covering a panoramic windshield 1' with a rectangular roof window area (right in 2A ) and a trapezoidal windshield area (left in 2A ) or a normal windshield 1 ( 2 B ).

The sunblind has a base web 2 and herewith continuously connected side parts 3A . 3B on that together with the basic train 2 on a winding shaft 6 on or can be processed by this.

The sunblind can with only one drive motor 16 be rolled up again or under relaxation of a preloaded torsion spring.

These are sledges 12A . 12B via a pull or pressure cable in or on guide rails 10A . 10B Moveable along the roof or A-pillar contour. The cables are connected by a common tooth or friction wheel of the electric drive motor 16 method. Alternatively, the slides 12A . 12B also via a gear drive, a cable drive, hydraulically or pneumatically.

The two sleds 12A . 12B are moved in parallel. To do both the change in distance of the guide rails 10A . 10B in the trapezoidal windshield area as well as the angle change between one with the base line 2 connected drawbar 11 and the guide rails 10A . 10B at the transition into a rectangular section of the windshield (right in 2 ) is the drawbar 11 in an embodiment (cf. 3 ) with the sledges 12A . 12B in a swivel joint 13 connected, which in turn via a longitudinally movable, elastically bound boom 14 with variable distance to the drawbar 11 is articulated.

3A shows the inserted boom 14 and the swivel 13 when the drawbar 11 in a rectangular disc area with parallel guide rails (right in 2 ) is positioned. 3B shows in contrast the extended boom 14 and the twisted swivel 13 when the drawbar 11 in a trapezoidal disc area with diverging guide rails (left in 2 ) is positioned. You can see the length and angle compensation between the towing bow 11 and guide rail 10B ,

In an alternative embodiment according to 4 is a rigid with the sled 12B connected boom 14 with angular play in a recess in the form of an internal bore 15 the hollow pull bow 11 guided. It can be seen that the boom 14 in the transition from a rectangular disc area with parallel guide rails ( 4A ) to a trapezoidal disc region with diverging guide rails ( 4B ) for length compensation partially from the recess 15 slips out and the angle change between Zugspriegel 11 and guide rail 10B by twisting in the recess 15 compensated.

In a further alternative embodiment according to 5 is the elastic, with the sled 12B connected outriggers 14 conical or sickle-shaped curved in the recess 15 guided. One recognizes in the sequence of figures 5A → 5B that the boom 14 in the transition from a rectangular disk area with parallel guide rails ( 5A ) to a trapezoidal disc region with diverging guide rails ( 5B ) partly from the recess 15 slides out while the angle change between the towing bar 11 and guide rail 10B compensated due to its curvature and under elastic deformation.

To center the Zugspriegels 11 and to ensure that the sun blinds throughout the winding and unwinding, are between the two arms 14 releasably one or more elastomers stretched, through the hollow drawbar 11 passed through and mechanically connected in the middle with this (see. 2 ). Alternatively, the drawbar 11 on each face by means of one or more springs with the carriage 12A respectively. 12B connected (not shown).

The drive 16 is preferably electrically operated. However, it can also be designed manually, hydraulically or pneumatically. On at least one of the two guide rails 10A . 10B There are sensors (not shown) that indicate the exact position of at least one slide 12A respectively. 12B to capture. The sensors can, for example ei NEN electrical switch, induction sensor, Hall sender or photosensor. They indicate at least the zero point, the end point and a stop position between the two points in order to allow two different routes: The stop position between zero and end point is selected so that the driver is not dazzled when the sun is low and still the Street can see. The end point is chosen so that the sun shade covers the entire windscreen to shade the interior of the parked vehicle.

The sensor also serves to prevent the sunblind from accidentally extending completely while driving. For this purpose, the drive control is connected to the central locking. If the vehicle is closed by means of a key or radio remote control, the drive control receives the signal to move the roller blind automatically from each current position to the end point, so that the interior is not heated by solar radiation through the windshield when the vehicle is parked. If the vehicle is opened by means of a key or radio remote control, the controller receives the signal to rewind the roller blind. It can be moved to the zero point, where it is completely on the winding shaft 6 is wound up. But it can also be a different predetermined position, for example, the holding position, approached.

So the scarf 2 . 3A . 3B in the clamped state does not sag in the interior, are additional crossbeams 17 (see. 6 . 7 ) with sled 18A . 18B proceed in the same guide rails 10A . 10B like the sledges 12AS . 12B are guided, but can also be performed in a separate pair of rails.

The crossbars 17 can be made up of multiple segments 17.1 . 17.2 respectively. 17.1 . 17.2 . 17.3 exist, as in 6B . 6C . 7A . 7B shown. In order to balance the path perpendicular to the direction of control (from top to bottom in 6 . 7 ), are the multipart crossbars 17 easy in itself ( 6B . 7B ) or multiple times ( 6C . 7A ) telescopic.

Additionally or alternatively, a carriage 18A with the crossbar 17 be firmly connected while this slidably on the other slide 18B ' is stored (see. 6A ). The double arrows in 6 . 7 indicate the displaceability of the cross bar 17 relative to the carriage 18B ' (see. 6A ) or its longitudinal variability (cf. 6B . 6C . 7A . 7C ) to guide rails 10A . 10B to follow with variable distance.

The crossbars 17 can be executed (cf. 6 ). In an alternative embodiment, these can be bent according to the shape of the roof (cf. 7 ). For example, they may be cylindrical, oval or rectangular and made of metal, plastic, composite or natural fibers, for example.

The crossbars 17 can be moved actively by means of a separate drive by means of tension, compression, cable, gear drive, hydraulic or pneumatic.

In a preferred embodiment, they are by means of a drag mechanism through the drawbar 11 proceed in the unwinding direction. The towing mechanism may include one or more pull ropes, tie rods, couplings, hooks and / or magnets such that a crossbeam 17 especially his sledges 18A . 18B respectively. 18B ' , detachable with another crossbar 17 or the drawbar 11 or whose carriage is coupled.

In at least one guide rail is a stop (not shown), also preferably made of metal, which is a crossbar 17 in a predetermined position of the Zugspriegel 11 decouples and stops. The crossbar 17 lingers in this position until the drawbar 11 him on his way back coupled again and takes. If several crossbars 17 are used, the rear pairs are coupled together and proceed simultaneously with the Zugspriegel 11 , The stops are arranged offset so that the crossbars 17 successively in predetermined positions of the towing bar 11 or the preceding crossbeam 17 decoupled or taken again in succession on the way back.
