Description

The invention relates to a motor vehicle door or a body, which has a window blind, which can be moved by a window motor with.

Currently, the trend is increasingly towards the use of window blinds to limit the heating of the vehicle interior and thus also to improve the effect of the air conditioning. Window blinds should also help to avoid glare.

For window blinds basically two different variants are known. One group of window blinds is powered by electric motors. These window blinds can thus be operated remotely by the driver, which significantly improves driving safety. But the effort is relatively large, because it requires an additional drive motor, which must be accommodated in the door next to the window motor.

Inside the door there is a notorious lack of space, caused by the existing passive and active personal protection systems, such as additional saponification and side airbags. Added to this is the space requirement of audio components, door lock actuation, ventilation ducts and the like. The accommodation of an additional motor for the window blind poses corresponding difficulties.

Appropriately so far are manually operated blinds whose space requirements within the door body are limited to the space for the winding shaft. But they are uncomfortable to use, especially not from the driver's seat.

From the DE 10 2005 012 208 A1 is a shading device for motor vehicle side window is known in which the drive is used for that electric motor, which is also used for operating the retractable window pane. The shading device is a dimensionally stable plate. Both the disc and the dimensionally stable plate are each moved via cables.

According to the one solution, an electromagnet is used to selectively couple a drive gear that is rotatably coupled to the driving electric motor with the window glass sheave or sheave sheave pulley. The gear is this moved axially on the motor shaft.

According to the other solution, a planetary gear is used, wherein the ring gear is coupled to the ring gear, while the planet carrier is used to drive the cable for the shading element. By means of a counting wheel, a gate valve is moved to selectively set the ring gear or the planet carrier, whereby either the window pane or the shading element is moved. This arrangement requires for trouble-free operation an exactly constant stroke of the window pane.

Based on this, it is an object of the invention to provide an arrangement in which the window blind and the retractable disc are independently movable with the same motor and which is insensitive to path tolerances.

This object is achieved with arrangements according to claims 1 or 2.

Advantageous embodiments of the invention are specified in the subclaims.

The term "vehicle door" is not to be seen directly limited to vehicle doors. It is also to apply to body sections, which are a rigid component and in which a retractable disc is housed.

A motor vehicle door usually has a body, which is hinged to the body and in which the essential door components are integrated.

The arrangement according to the invention can be realized both in doors in which the window is frameless, d. H. only the corpus exists. The implementation is also possible for doors in which a window frame spans the body above the window pane.

In the body, the window pane is movably guided. The guide can be done with the help of side parallel guide rails, as is common in windows with frame, or it may be provided a pivoting device, as used in rear side windows of convertibles.

In the body, a winding shaft is rotatably mounted next to the window. At this winding shaft, the roller blind is attached with an edge. The roller blind has a blank which corresponds at least approximately to the window pane.

At the edge remote from the winding shaft, the roller blind is connected to a tension rod. This tie rod does not necessarily extend over the full width, but may for example also have a shark fin-like shape.

In one embodiment of the invention, a spring motor is provided, which is coupled to the winding shaft in order to keep the roller blind tensioned at least in the position of use.

To drive the window or the roller blind two output gears are provided. The first output gear is drivingly coupled to the windowpane to convert a rotational movement of the output gear into movement of the windowpane to extend and retract the windowpane. The second gear is drivingly coupled via at least one line-shaped coupling element with the roller blind in order to convert a rotational movement of the second output gear in a linear movement of the roller blind in the sense of retraction and extension of the blind.

The assembly further includes a main drive motor whose drive force is sized to be able to operate the disc. Required for the largest operating force, because the disc has the largest weight.

Between the two output gears and the main drive motor a Umschaltkuppeleinrichtung is provided which is drivingly located between the drive motor and the two output gears. With the help of the switching clutch device, the main drive motor can optionally and temporally exclude each other, which put one or the other output gear in revolutions. By this new arrangement, a second voluminous drive motor is saved, which is otherwise used in the prior art to operate the roller blind. The Umschaltkuppeleinrichtung is much less space consuming than a complete second motor gear unit, which would be required in the prior art.

The new drive concept is also applicable to arrangements in which not the leading edge of the roller blind is moved over the electric motor, but the winding shaft, while the roller blind is biased at the front edge via a spring arrangement. In such a configuration, the second output gear is drivingly coupled to the winding shaft to transmit a rotational movement of the second output gear as a rotational movement of the roller shaft. The Umschaltkuppeleinrichtung, which finds application here, can be configured in the same manner as in the first-mentioned embodiment in which the drive of the roller blind is kinematically reversed.

The switching clutch device may include a clutch actuating motor.

The clutch actuation motor may be associated with a linkage arrangement which controls the movement within the transfer clutch assembly.

The switching clutch device may also include the main drive motor, which is pivotally mounted, for example, wherein the pivot axis is parallel or perpendicular to an output shaft of the main drive motor. The output shaft of the main drive motor need not be the armature shaft, but may for example be the output shaft of a transmission that is part of the main drive motor.

On the output shaft of the main drive motor can sit a spur gear, preferably a bevel gear or a worm. The two output gears can, depending on the space in the door axis parallel, for example, one above the other, be arranged, or coaxial side by side. In the case of the arrangement one above the other, the use of a worm gear is recommended, in which case the motor carries as a gear output a worm, which can be selectively brought by pivoting the motor with one or the other gear engaged.

If the two output gears are arranged coaxially with each other, it is advisable to use a bevel gear, which can also be driven by pivoting the motor optionally only one or the other output gear.

To move the window pane or roller blind, the respective output gear can carry a coaxial spur gear, which meshes with a flexible rack, which transmits the driving force to the window pane or the roller blind or the winding shaft. In the case of using a cable to operate the window, the relevant output gear is provided with a pulley, as is common in window regulators.

In order for the motor to be able to realize the switching clutch via a pivoting movement, it is advantageous if the two output gears are the same with regard to the tooth shape. A different tooth shape is also possible, in which case two corresponding counter gears must then be present on the output shaft of the main drive motor.

Depending on the driving force ratios or the desired paths, the drive sides of the two output gears can be equal or unequal in terms of the number of teeth.

As is apparent from the above, the output gears on the engine side can form a worm wheel, a spur gear, a crown gear or a bevel gear.

As the skilled artisan easily recognizes in the study of the following embodiment, the pivotal mounting of the main drive motor is merely an embodiment for realizing the switching clutch device. The literature knows a variety of Umschaltkuppeleinrichtungen that can naturally be used in a corresponding modification in the present invention. It would unnecessarily inflate the frame of the description of the figure, to mention here any conceivable variant. Suffice it to say that the Umschaltkuppeleinrichtung can also be realized via sliding sleeves and claws, the gears are constantly engaged with each other, if the pivotal movement of the engine is considered undesirable.

The body may, as is customary in vehicle doors or corresponding body sections, be bounded on the outside by an outer metal skin and inwardly by an inner lining.

In the case of a vehicle door, the body is hinged to the hinges on the vehicle body.

The upper edge of the body can form the upper edge of the door or the upper edge of the body in the case of frameless windows, as is the case for example with rear side windows of two-door convertibles. But it can also stretch a window frame over a carcass upper edge, in which case the carcass upper edge forms the lower edge of the window.

The guide means for the window pane may be guide rails which run only in the body. But it may also be guide rails, which run from the body in the window frame.

The winding shaft may, depending on the course of the edges of the disc to each other be a cylindrical or a conical winding shaft.

The winding shaft may be concealed in the body. In another embodiment, the winding shaft sits, depending on the door, on the front edge of the window or the rear edge of the window.

The roller blind can consist of a perforated foil or a knitted fabric.

To guide the tension rod guide rails or a support rod can be used. The support rod may be guided in a guide bush in the body.

In the drawing, an embodiment of the object of the invention is shown and explained thereafter.

1 shows a motor vehicle door overlooking the open body, illustrating the drive of the window and the roller blind.

2 illustrates the implementation of the Umschaltkuppeleinrichtung for selectively driving the window or the roller blind via a main drive motor.

3 and 4 show different operating states of the window pane and the roller blind.

In 1 is a rear left motor vehicle door 1 illustrated in a highly schematic not to scale representation. From the 1 All parts are omitted which are not required for understanding the invention but are of course available at every vehicle door. These include, for example, the door hinges, the locking device for the door, the lock parts for closing the door, speakers, air ducts and the like. The interior lining of the door 1 is removed to give a view into the door interior.

As the 1 lets recognize belongs to the vehicle door 1 a corpus 2 standing on a carcass top 3 ends. Above the carcass upper edge 3 spans a window frame 4 holding a window opening 5 together with the carcass upper edge 3 circumscribed. The window frame 4 consists of two leading away from the carcass frame frame parts 6 and 7 and a transverse frame section 8th together. Through a vertical bridge 9 the window opening is divided into two sections, a left, approximately triangular section 11 with fixed window pane arranged therein 12 and a right-hand section to the vehicle front 13 with a movable up and down window 14 , Around the windowpane 14 to be able to move, contains the bridge 9 as well as the right frame section 6 each one provided with a guide groove guide rail 15 . 16 , each one down to the body 2 into it continues. The window glass 14 is sized so that in the raised state the section 13 the window opening 5 completely closes. From the windowpane 14 is inside the body 2 its lower edge 17 recognizable. The lower edge of the window 17 runs parallel to the carcass upper edge 3 ,

The body 2 has in a known manner a cup-shaped in the broadest sense and is outwardly of the outer metal skin 18 and a circumferential sidewall 19 limited. The side wall 19 is contoured accordingly and has, depending on the body shape, different height.

The vehicle door is with a window blind 20 Mistake.

Below the carcass upper edge 3 is in the corpus 2 a kind of cassette 21 in which a winding shaft 22 of the window blinds 20 is rotatably mounted. The winding shaft 22 runs parallel to the carcass upper edge 3 and thus also parallel to the upper edge of the frame 8th ,

Like the broken section on the left side of the winding shaft 22 lets recognize, sits in the winding shaft 22 a spring engine 23 whose one end is with the body 2 is rotatably connected and the inner end of the tubular winding shaft 22 is anchored. With the help of the spring engine 23 , which is formed by a helical tension spring, is the winding shaft 22 biased in a sense of rotation.

For the execution of the spring engine 23 Many solutions are known from the prior art. Because the special type of spring motor 23 for the invention plays no role, the schematic representation is sufficient.

At the winding shaft 22 is a roller blind with one edge 24 attached. The of the winding shaft 22 remote edge of the roller blind 24 is with a pull rod 25 Mistake.

To the roller blind 24 to hold in the clamped state, is a support and management staff 27 intended. In the support or management staff 27 it is a cylindrical or profiled rod with a small diameter which is sufficiently kink-resistant to control the forces occurring during normal handling ausknicksicher.

For guiding the support rod 27 sits below the winding shaft 22 in the corpus 2 a guide bush 28 , The guide bush 28 is at a traverse 29 attached, located below the cassette 21 across the width of the body 2 , as shown, extends. With the help of this guide bush 28 is the carrier 27 in a direction perpendicular to the carcass upper edge 3 guided. As the figure reveals, is the support bar 27 with his out of the corpus 2 outstanding end at 30 with the pull rod 25 connected. At the inner end of the support rod 27 sits a side pointing driver 31 ,

The functional length of the support bar 27 follows from the following functional description.

To operate the windowpane 14 is a power window arrangement 32 intended.

To drive the window regulator 32 is a geared motor and clutch assembly 33 present, the sections of an unrecognizable sheave in sections 34 led rope 35 drives. The rope 35 may be an endless rope lying around a sheave in multiple passes, or it may be a rope whose ends are fixed to the sheave. The window regulator assembly 32 is thus executed in one of the known forms. The invention is not limited to the specific form shown.

From the geared motor and clutch assembly 33 the rope is running 35 to a first pulley 36 extending below the lower end of the guide rails 15 and 16 is rotatably arranged. The axis of the pulley 36 is perpendicular to the through the windowpane 14 defined level. It is rotatably mounted on support structures not shown further within the body. The rope section between the pulley 36 and the geared motor and clutch assembly 33 runs in a shell.

Following the pulley 36 forms the rope 35 a rope course 37 parallel to the guide rail 15 in the direction of the carcass upper edge 3 running.

Just below the carcass upper edge 3 there is a through the Traverse 29 and the cassette 21 Covered further pulley on which the rope 35 towards a deflector 38 is diverted. The rope section between the pulley 38 and the pulley below the carcass upper edge 3 again runs in a shell.

Following the pulley 38 forms the rope 35 again a Seiltrum 39 parallel to the rope run 37 and thus parallel to the guide rails 15 and 16 up to the carcass top 3 runs.

The pulley 38 is functionally at the same height as the pulley 36 and is parallel to the axis to this.

Axially parallel to the deflection pulley, that of the traverse 29 is concealed and attached to the Seiltrum 37 connects, there is another pulley, at the Seiltrum 39 ends up from there in a sheath section 41 to the geared motor and clutch assembly 33 to be returned.

Due to the described course of the rope 35 arise the two rope trumps 37 and 39 when starting the geared motor and clutch assembly 33 to move in the same direction parallel to each other.

At the two Seiltrummen 37 and 39 sit takeaway 42 and 43 , the tensile and compression resistant the Seiltrum 37 respectively. 39 with the lower edge of the window 17 connect.

The geared motor and clutch assembly 33 to drive the window regulator 32 is also used to operate the window blinds 20 used. To explain the necessary technical measures is in addition to 2 Referenced. There is the geared motor and clutch assembly 33 shown schematically in a perspective exploded view. Parts that are not required for the understanding of the invention are omitted from the figure in order to improve the clarity of the figure. The figure is accordingly striking.

To the geared motor and clutch assembly 33 belong to a main engine 45 , which optionally has a gearbox 46 is assigned, two output gears 47 and 48 , a backdrop arrangement 49 as well as an auxiliary drive 51 for the backdrop arrangement 49 ,

The housing in which the mentioned parts are stored, has been omitted for clarity. The skilled person can supplement the necessary parts for this without inventive step from his knowledge.

In the main drive motor 45 it is a permanently energized electric motor 57 , at whose armature shaft the gearbox 46 connected. The gear 46 forms an output shaft 52 on which a bevel pinion 53 rotatably seated.

The main engine 45 is with the help of two tabs 54 , of which only one can be seen because of the aborted representation in the figure, on an axis 55 pivoted. The axis 55 is parallel to the axis of the output shaft 52 , The pivot axis 55 is in two storage blocks 56 stored stationary.

In this way, the main drive motor 45 a limited pivoting movement about the axis 55 Perform, the axis-parallel to the output shaft 52 lies. This allows the bevel pinion 53 referring to the illustration in 2 move a little to the right or left. This movement is exploited to the pinion 53 optionally with one of the two output gears 57 or 58 to couple.

The two output gears 47 and 48 are mounted coaxially with each other in the housing, not shown. The gear 47 is a crown wheel with one to the bevel pinion 53 complementary teeth. On the back, ie the side facing away from the viewer, carries the output gear 47 a pulley, on the above-mentioned rope 35 can be driven in the manner explained.

On the back of the output gear 48 , which is also designed as a ring gear, sits a spur gear 57 for driving a flexible rack 58 ,

At the flexible rack 58 it is a structure with a cylindrical flexible soul 59 on the outside of which at least one continuous spiral 61 firmly attached. This creates a kind of helical toothed rack. With the help of this rack 58 becomes the rotational movement of the output gear 58 on the window blind 20 transmitted, as will be explained in detail below.

The spur gear 57 is on its outer peripheral surface designed so that the flexible rack 58 positively with the gear 57 interacts. The measures that are required to the rack 58 with the spur gear 57 To hold in, for example, consist in a housing bore, which is tangential to the spur gear 57 leads past.

The axial distance between the two gears 47 and 48 is greater than the effective diameter of the bevel pinion 53 equivalent. This will ensure that the bevel pinion 53 either only with the gear 47 or just with the gear 48 completely engaged. An intermediate position in which the bevel pinion 53 optionally with both gears 47 . 48 combs, can be taken consciously, provided that in the end positions of engagement with the other output gear 47 or 48 is completely interrupted.

The gearbox from the gears 53 . 47 . 48 becomes at the same time the switching clutch to the pinion 53 Optionally either to the gear 47 or the gear 48 to couple.

To accomplish the switchover is the gate assembly 49 intended. The backdrop arrangement 49 contains a link plate 63 with a profiled opening 64 through which the output shaft 52 leads through. The width of the opening 64 in the direction perpendicular to the longitudinal extent of the output shaft 52 corresponds to their diameter. With the help of guides, not shown, the plate 63 in the direction perpendicular to the longitudinal extent of the output shaft 52 be guided.

The backdrop opening 64 is made up of an upper straight section 65 a sloping section 66 and a turn straight lower section 67 together. The two sections 65 and 67 are parallel to each other and, as the figure shows, spaced apart in the vertical and in the horizontal direction. They are laterally offset from each other and are by the oblique section 66 connected with each other. The offset between the vertical straight sections 65 and 67 corresponds to the stroke that is required for the bevel pinion 53 either completely with the output gear 47 meshes, or the output gear 48 , The sections 65 and 67 lie parallel to the direction of movement of the link plate 63 ,

To move the gate assembly 49 serves the auxiliary drive 51 , The auxiliary drive 51 includes a small geared motor 68 , whose output shaft 69 designed as a threaded spindle. The threaded spindle 69 is in a threaded sleeve 71 screwed in, which has a connector 72 with the scenery plate 63 connected is.

The auxiliary drive 51 serves as a clutch actuation motor, with which required for engaging pivotal movement of the main drive motor 45 is accomplished.

As will be readily apparent to one skilled in the art, the direction of movement is that provided by the combination of the threaded spindle 69 and the threaded sleeve 71 can be generated, parallel to the straight sections 65 and 67 the backdrop opening 64 and thus at right angles to the longitudinal extension of the output shaft 52 ,

If by putting the auxiliary drive in motion 51 the scenery plate 63 is guided in the upper end position, leads the output shaft 52 through the lower straight section 67 the backdrop opening 64 , This is the main drive motor 45 , pivoted relative to the representation of the figure in the right end position. In this situation meshes the pinion 53 with the ring gear 48 , If, however, the link plate 63 with the help of the screw drive from the threaded spindle 69 and the threaded sleeve 71 shifted down to the lower extreme position, the output shaft runs 62 through the upper section 65 the backdrop opening 64 , bringing the main engine 45 is pivoted in the left end position. In the left end position the pinion gear meshes 53 with the output gear 47 while it's off the output gear 48 completely uncoupled.

From the explanation also shows that it is appropriate, the width of the gate opening 64 at all points to the diameter of the output shaft 52 adapt, so that the radial play, which is the output shaft 52 in the backdrop opening 64 has, not enough, to the bevel pinion 53 from the desired output gear 47 or 48 disengage, or a two-sided engagement with both gears 47 and 48 to enable at the same time.

The way as the rotational movement of the output gear 47 with the help of the pulley and the rope 35 on the movement of the windowpane 5 is already described above. To operate the window blinds 20 is the flexible all-round toothed rack 58 intended. The rack 58 is with its empty strand in a storage tube 75 guided, that of the gear housing of the geared motor and clutch assembly 33 leads away. The workstring runs ausknicksicher in a guide tube 76 leading to a slotted guide rail 77 leads. The guide rail 77 extends parallel to the support bar 27 and has a slot 78 on, by the one on the rack 58 fastened driver outward exit, with the driver 31 of the support rod 27 coupled in both directions of movement.

To explain the operation is of a state according to 1 went out. In this state is the windowpane 5 raised to close the window. The roller blind 24 is on the other hand, on the winding shaft 22 wound up, with the aid of the spring force of the spring motor 23 , This means that the support bar 27 in its lowest position stands and the rack 58 from the guide rail 77 completely withdrawn, bringing it in the slot 78 is not visible.

If the user, starting from this position, wants to open the window, he actuates the associated switch provided in the vehicle. By a corresponding ingenious control is ensured that initially the auxiliary drive 51 is set in motion to the backdrop plate 63 to bring in the lower end position, in which the output shaft 52 of the main drive motor 45 through the section 65 the backdrop opening 64 leads through. Switching on the auxiliary drive 51 happens every time to save a position feedback of the switching clutch.

In the lower position of the link plate 63 is, as mentioned above, the main drive motor 65 towards the output gear 47 pivoted out. The output pinion 53 thus stands exclusively with the output gear 67 engaged. After a corresponding waiting period, which depends on the working cycle of the auxiliary drive 51 is tuned to the hub of the link plate 63 to go through then the main drive motor 45 energized and then turns into turns. The output pinion 53 runs and drives the output gear 47 on, causing the rope 35 is set in motion, in the sense that its working volume 37 and 39 move down and over the drivers 42 and 43 the disc 5 Lower. At any point you can turn off the power supply to the main drive motor 45 the window glass 5 be stopped. In the position after 3 is the disc 5 completely lowered and thus the window open maximum.

To close the window, in turn, as previously mentioned, first the auxiliary drive 51 set in motion to make sure that the gate plate 63 the lower position occupies the engagement of the output pinion 53 in the output gear 47 to make sure. Then the main drive motor 45 set in motion in the reverse direction which causes the working stream 37 and 39 of the rope 35 to move up and the disc 5 also push it up until the desired position is reached, at which point the user will be the main drive motor 45 still sets.

Next, suppose the user wants the window blind 20 shut down. For this purpose, he operates a corresponding control switch, which is mounted at a suitable location next to the user, in the case of the driver, for example, in the left side door or in the center console. By the operation of this control switch is first the auxiliary drive 51 set in motion to the backdrop plate 63 to bring in the upper end position. This is achieved by the screw spindle 69 into the threaded sleeve 71 is screwed into it. As the geared motor 68 is stationary, this screwing causes a raising of the link plate 63 up. The output shaft 52 slides through the S-shaped cranked gate opening 64 from the section 65 through the sloping section 66 in the lower section 67 , The section 67 is opposite the section 65 to the right towards the output gear 48 relocated. The main engine 45 gets on the axis as a result 55 , based on 2 to the right, pivoted, so that the output pinion 53 with the output gear 48 engages. In the end position of the gate plate 63 in which the output shaft 52 only in the thigh 67 is the geared connection between the output pinion 53 and the output gear 47 completely interrupted, however, with the output gear 48 produced.

After a corresponding waiting time, the swinging of the main drive motor 45 in the other pivot position corresponds, the main drive motor 45 set in motion, which is now no longer the gear 47 but the gear 48 drives. The rotational movement of the drive output gear 48 is about the flexible rack 58 or his workstrum, that through the shell 76 runs on the driver 31 transfer. The rack 58 gets in the slotted guide rail 77 moves upwards and takes the driver 31 in the upper end position with. Accordingly, in 4 in the slot of the guide rail 77 the rack 58 visible, noticeable.

Due to the upward movement of the workstrum of the rack 58 in the slotted guide rail 77 is the thus positively locking two directions of movement coupled support bar 57 pushed up towards the top of the window. It takes the support rod 57 the tie rod 25 with and pulls the roller blind 24 against the action of the spring engine 23 from the winding shaft 22 from. The end position shows 4 , After reaching the end position is forcibly the power for the main drive motor 45 off.

The retraction of the roller blind 24 happens analogously in the opposite direction. First, when operating the control switch for the window blind 20 again the auxiliary drive 51 set in motion to ensure that the geared connection between the output pinion 52 and the output gear 48 is made before the power for the main drive motor 45 is turned on. The turning on of the current happens with reversed polarity, which means that with the help of the main drive motor 45 the rack 48 from the guide rail 77 is withdrawn. Due to the positive coupling on the driver 31 with the rack 58 becomes the support rod 27 pulled down. To the extent that the support bar 27 wandering down, is the spring engine 23 capable of the roller blind 24 on the winding shaft 22 wind.

As is apparent from the functional description, only a single powerful main drive motor is used, which via a switching clutch, formed by the gear 53 and the two output gears 47 and 48 and the auxiliary drive 51 with backdrop 49 Optionally, move the window or roller blind. The auxiliary drive motor 51 can be performed very low performance, since he only has to overcome the force that is necessary to the main drive motor 45 between the two end positions, in which he either with the gear 47 or the gear 48 is coupled, swinging back and forth.

A special control of the engine 51 may be unnecessary. Suffice it for the duration of operation of the main drive motor 45 remains switched on, wherein the movement stroke, by the auxiliary drive means 51 is reached, is blocked by end stops accordingly.

The space requirement of the new arrangement is very small, because no space has to be created for a separate main drive motor, as is necessary in the prior art, which needs two motors, one for the movement of the window and the other for the movement of the window blinds. In the invention, a space-consuming main drive motor is sufficient for this purpose. The switching device, however, requires extremely little space and can also be right next to the main drive motor 45 be housed.

For the expert is due to the given explanation of the invention also readily apparent that a kinematic reversal is possible, which consists in that the window blind 20 interacts with a spring device which on the roller blind 24 , at the front edge of which attacks, while the rack 58 interacts with a gear that rotatably with the winding shaft 22 is coupled. The operation with respect to the double utilization of a main drive motor is maintained.

It will also be readily apparent to those skilled in the art that this solution principle is also applicable to arrangements in which the tension rod 25 not with the help of the support rod 27 held and guided, but with the help of two guides, both sides of the blind 24 run and in which the tension rod 25 slides at the end.

Finally, it can also be seen that the winding shaft 22 does not necessarily have to be arranged on the lower edge of the window. It can also, for example, in the area of the window leading edge 7 be stored, in which case the blind 24 is moved from top to bottom according to the representations, but from right to left over the entire window width including the small window portion Deecksfenster 12 ,

In case of using the drive concept in the front side door, the roller blind runs 24 in the vehicle longitudinal direction, only in the permissible upper area of the side window. Due to the approval regulations, the shading of the front side windows must not be done over the entire window height, but must be limited to an upper area depending on the geometry of the vehicle. The drive concept is also applicable to such window blinds anyway.

Finally, the person skilled in the art recognizes that the drive solution according to the invention is not limited to side windows of doors. It can also be applied to two-door variants, in the rear side window area, which is an integral part of the body.

The type of switching clutch shown is only one conceivable, but advantageous variant. There are still other switching clutches in question for which there are enough examples in the literature.

Apart from the use of a bevel gear, it is also possible to use worm gear. In this case, then advantageously the output gears 47 and 48 arranged as worm wheels one above the other, while in the gap between the two gears, the worm dips, instead of the bevel pinion 53 on the wave 52 rotatably seated.

The slide guide is then arranged so that the worm can be moved up or down to be coupled to either the worm wheel at the top or the worm wheel at the bottom.

A motor vehicle is equipped with a combined drive for the movement of the window and the roller blind. In this case, one and the same main drive motor is used to move the window or the roller blind, which is coupled via a switching device with either a power transmission system for the window or the power transmission system for the roller blind. As a result, space is saved in the door to a considerable extent.
