Description

The The invention relates to a door assembly for one Motor vehicle door according to the preambles of the claims 1 and 3.

A Such door assembly has an adjusting device for adjusting an adjustment with a drive device, one on the door assembly extending traction means for transmission an adjusting force of the drive device on the adjustment and a Umlenklenkelement for deflecting the traction means to a Deflection axis. The traction means is so around the deflecting element guided, that there are two sections extending from the deflecting element, of which a section is between the deflector and the Drive device extends.

at the generic door assembly performs the Deflection element, for example, designed as a steel cable traction means and deflects this in such a way that the desired course of the traction means along the door assembly results. For example, runs in a single-stranded one Window lift the traction means of a drive device towards a first deflecting element, from the first deflecting along a guide rail, along which a driver for connecting the traction means with the is performed to adjusting adjusting part, to a second Deflection element and of the second deflection element back to the drive device. To adjust the adjustment moves the drive device the traction means and moves over the Traction means the driver and thus the adjustment along the guide rail.

The Traction means thus serves for the transmission of adjusting forces from the drive device to the adjustment part and is through guided the deflection, to the adjusting force in the desired Transfer adjustment to the adjustment. To ensure, that the traction means is guided safely and reliably on the deflecting element and especially with a big one acting on the traction means adjusting the traction means not of jumps the deflection, the traction means in the region of the deflecting element so led be that the two extending from the deflector sections perpendicular to the deflection axis of the deflection in the deflection enter. Running at least one of the sections at an oblique angle in the deflecting element a, so there is a risk that the deflecting the traction means can not hold and the traction device jumps from the deflector.

conventional door assemblies are common nowadays designed such that it is optional with an electric or Manual drive device can be fitted. The electric drive device and the manual drive device Here are usually at different locations on the door assembly to arrange, so that in dependence from the use and arrangement of an electrical or manual Drive device give different courses of the traction device. Due to the different arrangement of the drive devices is it then usually not possible to arrange the deflecting element and align that the traction means both when using an electric drive device as even when using a manual drive device in optimal Angle enters the deflection.

at a door assembly with a carrier element, optionally with a manual or electric drive device be equipped is, the orientation of the deflecting thus only for a course traction means - either for the electric drive device or the manual drive device - optimized become. If the deflection element is arranged such that the orientation her perpendicular to the deflection axis facing deflection level the course adapted to the traction means of the manual drive device, the deflection level for the course of the traction means of the manual drive device in desired Angle to the plane defined by the traction means plane, it runs Traction means when replacing the drive device and using a electric drive device at an oblique angle in the deflection so that the risk exists that the traction means in the operation of Adjustment of the deflecting jumps.

At one of the DE 39 06 682 A1 Known door assembly, a cable guide means is used in the form of a Bowden system to guide the traction means between the drive device and the deflector. The traction means extends almost over its entire length in a closed Bowden tube between the drive device and the deflecting element and is held in the region of the drive device and the deflecting element in each case by a Bowden holder such that the traction means runs at a desired angle in the deflecting element. By using the Bowden system, the traction means is thus guided between the drive device and the deflecting element on its entire path in the closed Bowden tube, which increases the required number of parts and the complexity in the construction of the door assembly.

The present invention has for its object to provide a door assembly for a motor vehicle door, which is ensured in a cost effective manner using a minimum of additional components that a safe Füh tion of the traction means is ensured on the deflecting element for different drive devices.

These The object is achieved by an object having the features of the claim 1 solved. According to the invention here is provided that the cable guide means located between the deflector and the drive device extending portion of the traction device in the circumferential direction only partially surrounds, the cable guide means is formed, which is located between the deflecting element and the drive device to extend extending portion of the traction device such that the two sections of the traction means in the region of the deflecting element within a desired Angle to a perpendicular to the deflection axis extending deflection plane run.

Prefers The two sections run here to ensure safe guidance of To ensure tension means on the deflecting element, substantially parallel to the deflection plane of the deflection element. Under "essentially parallel "is too Understand that the traction means within a flat, also referred to as the tolerance opening angle Angle to the deflection plane enters the deflection. The through the two sections The plane spanned in the region of the deflecting element of the traction element extends in each Fall within the desired angle to the deflection plane and ideally parallel to the deflection plane.

The The present invention is based on the basic idea, on the one Side to use a traction device that is free, so without use one of the traction means almost over its entire length leading and completely surrounding Bowden tube extends between the drive device and the deflection element, but on the other hand, the way the traction device between the drive device and the deflection by an additional cable guide means be determined so that the traction means at an optimal angle in the deflecting element enters and thus it is ensured that the traction means in operation not can jump from the deflector. The cable guide means according to the invention allows here on simple and inexpensive Way to adjust the course of the traction device without consuming Management systems, such as Bowden systems, required to guide the traction device would.

The additional Rope guide means allows in particular the use of different drive devices, which are arranged at different positions of the door assembly and thus different courses require the traction means, wherein by means of the cable guide means it is ensured that independently from the particular drive device used and their positioning the Traction means in desired Angle relative to the deflection plane enters the deflection.

The Task is about it beyond by an article having the features of claim 3 solved. According to the invention here is provided that the support element is set up to accommodate the drive device in different Positions on the support element, being dependent from the position of the drive device on the carrier element different courses of the between the deflector and the drive device extending portion and formed the cable guide means and is provided depending from the course of the between the deflector and the drive device extending portion of the traction means for guiding cooperate with the traction means or not to cooperate.

advantageously, is the rope guide means too in this solution formed, which is located between the deflecting element and the drive device extending section of the traction means depending on the course of the section to lead like this that the traction means independent from the position of the drive device on the door assembly in the region of the deflection at the desired angle to a vertical extends to the deflection axis extending deflection plane.

In In a preferred embodiment, the deflection element is a deflection roller formed, which is about a deflection axis corresponding axis of rotation rotatably on the carrier element is arranged. Such a pulley allows a low-friction, rolling guide the traction means on the pulley. Fundamentally conceivable, however Other embodiments of the deflection, for example as fixed guide piece with an at least Sectionally in the circumferential direction round guide area or channel, the one to be led is adapted.

Preferably, the cable guide means is designed as a guide section, over which the extending between the deflecting element and the drive device portion of the traction means is slidably guided. The guide section can be designed, for example, as a raised region which guides the sliding means in a sliding manner, but also by other guide means, for example a rotatable guide roller, a guide channel or the like. The cable guide means thus serves as an additional deflection means, which deflects the traction means between the drive device and the deflecting element in such a way that the traction means enters the deflecting element at an optimal angle and can not jump from the deflecting element during operation. Essential is here in that no complex guide system for guiding the traction means is provided, but adapted and determined by means of the cable guide means the path of the traction means between the drive device and the deflecting element.

The Drive device can be used as an electric drive device or be formed manual drive device, wherein the carrier element the door assembly optionally with the manual drive device or the electric Drive device equipped is. Dependent of whether for the adjusting device thus a manual or an electrical Drive to be used comes a manual or an electric Drive device for use, wherein on the support member receptacles or fastening devices provided for attachment of the electric or manual drive device are. The carrier element is here designed such that the electric drive device and the manual drive device at different locations of door assembly are to be arranged, taking measures at the respective locations for mounting the electric drive device and the manual Drive device are provided.

Depending on the use of the electric drive device or the manual Drive device then result in different courses of the Pull means along the door assembly. advantageously, is the cable guide these different courses adapted to the traction means, so that with a uniform orientation and positioning the deflecting element both an electrical as also a manual drive device can be used and the two sections independently on the type of drive used and the course of the traction device along the door assembly in the region of the deflection at the desired angle to the deflection plane run so that independent from the drive device used and their positioning both sections always in desired Retracting angle in the deflection and not in operation of the Deflecting element can jump.

The Deflection element of the adjustment of the door assembly is on the support element the door assembly arranged and aligned relative to this. The orientation of the Deflection plane of the deflecting element is in this case a certain course of the Traction means adapted for the traction means extends from the drive device towards the deflection element, within a desired Angle to the deflection plane enters the deflection and yourself within the desired Angle of the deflector, for example, along a guide rail extends to a further deflecting element. For this course of the traction device the orientation of the deflection element is optimized, the deflection plane within the desired Angle to the tensioned by the traction means in the region of the deflecting element Level passes. Under the desired Angle here is the angle between the by the traction means in Area of the deflecting plane spanned and the deflection plane to understand, within which the traction means securely on the deflecting element guided is, so does not jump from the deflector. Is this going? Traction means in a more oblique Angle, that is outside the desired angle in the deflection, so there is a risk that the traction means jumps in the operation of the adjustment of the deflection.

For example can in this way the orientation of the deflecting the course the traction device when using a manual drive device be adjusted. However, becomes an electric drive device used at a different location on the door assembly, This results in a different course of the traction means for which the Alignment of the deflecting element is not optimal. To others too Positioning of the drive device and the resulting other Course of the traction means to ensure that the traction means is safely guided by the deflecting element during operation, is the cable guide means provided, that with changed Course of the traction means cooperates with the traction means such that the Traction means in the region of the deflecting element in each case within of the desired Angles to the deflection plane and the two extending from the deflector sections of the traction means thus extend in the deflection plane.

Advantageously, the cable guide means is in this case designed such that, depending on the use of the electric drive device or the manual drive device, it cooperates or does not cooperate with the section of the traction means extending between the deflection element and the drive device. It is conceivable, for example, to optimize the orientation of the deflecting element on the course of the traction means when using the manual drive device. In this case, the cable guide means does not interact with the traction means when using the manual drive device, but only when using the electric drive device and the resulting other course of the traction device. Conversely, if the orientation of the deflecting element is optimized for the course of the traction device when using the electric drive device, then the cable guide means influences the section extending between the deflecting element and the drive device only when using the manual drive device and resulting trajectory of the traction device. It is also conceivable in this context that the cable guide means for both courses the traction means - when using the manual drive device and the electric drive device - cooperates with the traction means for guiding and the course of the traction means is in each case adapted such that the traction means runs regardless of its course in the desired angle in the deflection. In this way, the deflection can be aligned independently of the course of the traction device to some extent, for example, optimized for the spatial conditions or the course of a guide rail, being ensured by the cable guide means in the course of the traction means both for the electric drive device and for the manual drive device is that both when using the electric drive device as well as when using the manual drive device, the traction means within the desired angle enters the deflection.

In an advantageous embodiment is the support member of the door assembly designed as a carrier plate, at the adjusting device together with other functional components the door assembly is arranged. For example, you can on the carrier plate as additional functional components a loudspeaker, a door lock or the like may be arranged.

advantageously, has the on the support plate arranged adjusting device further comprises a guide rail, along of which at least a portion of the traction device is guided. The guide rail can in this case, in particular when using a plastic formed Support plate one piece to the carrier plate be formed. However, it is also conceivable to use a guide rail, as a separate, with the door assembly is formed to be connected component. The adjusting device can be kind of a single-stranded Window lifter be constructed, in which the traction means of the Drive device to a first deflecting element, of the first Deflection element along the guide rail towards a second deflecting element and from the second deflecting element back to Drive device extends. It is also conceivable, however, an adjustment in the manner of a double-stranded To use cable window lifter, which has two guide rails on whose ends each have a deflecting element is arranged between which the traction means in the form of a closed, intersecting rope loop extends.

In An advantageous development is the guide rail of the adjustment curved, being the curvature the guide rail the curvature the adjusting part to be adjusted, in particular a window, adjusted, and the curved Adjustment of the adjustment defined.

Prefers is the deflecting element of the adjusting device at one end of the Arranged guide rail, as a guide section trained cable guide means to the guide rail or the carrier plate is formed in the region of the deflecting element. As stated above the cable guide means in this case one to the guide rail or the carrier plate integrally formed deflecting element, which is towards the deflecting element extending traction means acts such that the traction means in optimal Angle enters the deflection.

is the guide rail or the carrier plate made of plastic, so the cable guide means in a simple manner to the guide rail or the carrier plate be sprayed. It is also conceivable, however, as a cable guide means a separate, with the guide rail or the support plate too to use connecting component in his material and his Sliding properties designed, for example, as a steel cable Traction means for low-friction guidance is adjusted.

In A preferred embodiment of the invention is the deflection axis of the deflecting element arranged on the door assembly such that in a normal position during normal operation in the desired Way is aligned and the traction means within the desired Angle enters the deflection. It is also conceivable the deflection axis in this normal position slightly against a loading direction to tilt and the deflection plane relative to that through the sections tilt the traction means spanned Zugmittelebene.

advantageously, is provided that even with an above-average burden the deflecting element by the traction transferring traction means in operation the adjusting device, wherein the deflection axis of the deflecting element optionally slightly tilted from the normal position, the traction means within the desired Angle enters the deflection and thus safe to the deflection guided is. The idea behind this is that the deflection element in his Alignment and dimensioning is designed so that even at maximum load of the deflection element, the deflection axis of the deflection not or only slightly tilted to Zugmittelebene and the traction means at least within the desired Winkels runs, so that it is ensured that even at maximum load the Pulling means can not jump from the deflecting element.

In this context, the deflecting element preferably has a guide groove arranged on the circumference of the deflecting element, in which the traction means forming the two sections is guided on the deflecting element. The guide groove has egg NEN tolerance opening angle in a plane perpendicular to the deflection plane, in the region of which are introduced into the guide groove portions of the traction means are guided on the deflecting element. Only within the tolerance opening angle a secure guidance of the traction means is ensured on the deflector. Runs at least a portion of the traction means at an oblique angle of entry, which is outside the range of the tolerance opening angle, in the guide groove, the guide groove can not hold the traction means and the traction means jumps from the deflecting element.

Around to ensure, that the traction means in the operation of the adjustment safely from guided the deflector is, therefore, the deflecting element is aligned and dimensioned, that for all load conditions the portions of the traction means within the range of the tolerance opening angle run into the deflection. The deflecting element is in this case dimensioned that the rotation axis even at a maximum load in load direction only tends so far that the sections the traction means still within the range of the tolerance opening angle run and thus the traction means is securely guided by the deflecting element.

conventional Driving devices for driving a trained as a rope Traction means comprise a cable drum onto which the traction means and unwound, so as to the traction means and together with the To move the traction means connected to the traction means adjustment. By winding and unwinding of the traction device on the cable drum can be in known from the prior art adjusting the course of the between the drive device and the deflecting element extending portion of the traction means in the deflection in dependence change from the adjustment of the adjustment. Preferably acts the cable guide means Therefore, on the between the drive device and the Deflection element extending portion of the traction means that the Section independent from the adjustment position of the adjusting device in the region of Deflecting element within the desired Angles to the deflection plane and thus enters the deflecting element at an optimal angle. through the cable guide means Thus, it is ensured that the entry angle of the between the deflecting element and the drive device extending portion independently from the adjustment of the adjustment when adjusting the adjustment is constant and does not change with the adjustment.

In 1 to 6 is an embodiment of a door assembly according to the invention 1 shown, either as in 1 to 3 an electric drive device is shown 25 or, as in 4 to 6 shown, a manual drive device 26 having. The electric drive device 25 or the manual drive device 26 This is part of an adjustment 2 in the form of a single-stranded window lift, mounted on a support plate 10 is arranged. The adjusting device 2 has a guide rail 21 on, which is designed as a separate stamped sheet metal part and with the support plate 10 over this intended attachment points 210 connected is.

The carrier plate 10 is part of a door module of a vehicle door of a motor vehicle and is formed via attachment points 11 to be arranged and fastened to a door inner panel of the vehicle door. The carrier plate 10 can be made of plastic or metal and covers in mounted on the vehicle door condition an opening in the door inner panel of the vehicle door in a known manner from moisture-tight. The carrier plate 10 serves to accommodate functional components of the vehicle door, such as a speaker, the adjustment 2 , a door lock or other Components of the vehicle door. How out 1 and 4 can be seen, the support plate 10 For this purpose, for example, a speaker recording 12 on, in which a speaker is inserted and on the carrier plate 10 can be pre-assembled.

In principle, in another embodiment of the vehicle door, the adjusting device can also be arranged on a door inner panel of the vehicle door, possibly using a small-area base plate. Although below based on the carrier plate 10 described the door module, the adjusting device according to the invention is not limited to applications in combination with a support plate.

The on the carrier plate 10 arranged adjusting device 2 is constructed in the manner of a single-strand cable window lifter with a guide rail 21 along which a driver 22 with a disc holder 23 is slidably guided for receiving a the adjustment part forming window. As in particular from 2 . 3 . 5 and 6 it can be seen is the guide rail 21 curved, wherein the guide rail 21 in its middle area forms a belly, that of the carrier plate 10 protrudes, and at its two ends via attachment points 210 is connected to the carrier plate.

The adjusting device 2 has a drive device that serves as an electric drive device 25 (please refer 1 to 3 ) or manual drive device 26 (please refer 4 to 6 ) is trained. The adjusting device 2 also has a traction device 24 on, which forms a closed loop of rope, whose course through the drive device 25 respectively. 26 and pulleys 27 . 28 , which form deflecting elements and are rotatable about a respective axis of rotation corresponding to the deflection axis (see the axis of rotation D of the deflection roller 27 in 2 . 3 . 5 . 6 ), at the two ends of the guide rail 21 is fixed. The traction device 24 extends from the drive device 25 respectively. 26 towards the pulley 27 at the upper end of the guide rail 21 , from the pulley 27 along the guide rail 21 to the pulley 28 at the lower end of the guide rail 21 and from the pulley 28 back to the drive device 25 respectively. 26 and thus forms a closed loop of rope. During operation of the adjusting device 2 drives the drive device 25 respectively. 26 the traction device 24 and moves the with the traction means 24 firmly connected driver 22 along the guide rail 21 , By the displacement of the driver 22 along the guide rail 21 This is the way about the disc mount 23 with the driver 22 to be connected window (in 1 to 6 not shown) also along the guide rail 21 moved and the window of the vehicle door closed or opened.

The guide rail 21 is adapted in its curvature of the curvature of the window and defines a curved displacement of the window. It should be noted at this point that the underlying idea of the present invention is not limited to the use of curved guide rails, but also in completely different kind of guide rails, such as straight or otherwise shaped guide rails, can be applied.

In the 1 to 6 illustrated carrier plate 10 the door assembly 1 is to be equipped with either an electric drive device 25 or a manual drive device 26 formed and has openings for this purpose 13 . 15 and attachment points 14 . 16 on, in which either an electric drive device 25 or a manual drive device 26 used and with the carrier plate 10 can be connected. Such, in two ways equippable carrier plates 10 have the particular advantage that a uniform carrier plate 10 in a cost effective manner for different configurations of a vehicle door - either in a cost effective version with a manual drive device 26 or in a more expensive variant with an electric drive device 25 - can be used. Depending on the customer's preference, the door assembly becomes 1 with an electric drive device 25 or a manual drive device 26 equipped, with only the drive device is selected individually, all other components of the adjustment 2 , in particular the guide rail 21 , the driver 22 and the pulleys 27 . 28 but uniform and independent of the choice of the drive device on the support plate 10 to be ordered.

As compared to 1 and 4 becomes clear, is the electric drive device 25 represented in 1 , at another place on the carrier plate 10 arranged as the manual drive device 26 represented in 4 , This is due to the fact that the manual drive device 26 at the point on the carrier plate 10 the door assembly 1 is to be arranged at which a vehicle occupant to the drive device 26 , in particular one with the drive device 26 connected and accessible in the vehicle interior of the vehicle crank can access. The position of the manual drive device 26 on the carrier plate 10 thus depends essentially on the ease of use for a vehicle occupant.

Such a restriction exists for an electric drive device 25 not, so the electric drive device 25 in a spatially favorable position on the support plate 10 in close proximity to the guide rail 21 can be arranged, as in 1 is shown.

As compared with 1 and 4 results, depending on the use of either an electric drive device 25 according to 1 or a manual drive device 26 according to 4 different courses of the traction device 24 between the drive device 25 respectively. 26 and the pulleys 27 . 28 , When using an electric drive device 25 forms between the drive device 25 and the pulleys 27 . 28 extending, by the traction means 24 formed rope loop from a relatively flat triangle, while using the manual drive device 26 there is a relatively large triangle.

The electric drive device 25 points, in particular in 2 it can be seen, a cable drum 252 on, in one over attachment points 251 with the carrier plate 10 connected housing cover 253 on a drive shaft 254 is rotatably mounted. The drive shaft 254 extends through the opening 15 (please refer 4 ) through the carrier plate 10 through from the on a wet room side of the carrier plate 10 arranged cable drum 252 to the back of the carrier plate 10 , corresponding to a dry room side of the carrier plate 10 to be in the back with a in 1 to 3 not shown to be connected electric drive motor. The rope drum 252 winds the traction device 24 in the operation of the adjusting device in a known manner in the manner of a single-strand cable window lifter up and down, wherein upon winding of the one end of the traction means 24 at the same time the other end of the traction device is handled. In this way, the traction means 24 moved and the driver 22 for adjusting the with the driver 22 driven window pane.

The manual drive device 26 also has a cable drum 265 on top of a mounting bracket 263 (please refer 5 and 6 ) on a mounting plate 262 rotatably mounted and over the mounting plate 262 and attachment points 261 with the carrier plate 10 connected is. The rope drum 265 is on a drive shaft 266 arranged, extending from the cable drum 265 to the back of the carrier plate 10 extends and a shaft 267 comprising, with a crank for manual operation of the drive device 26 can be connected by a vehicle occupant. In to the electric drive device 25 analogously, the traction means 24 on the rope drum 265 wound up and down and in this way to drive the driver 22 postponed.

When using the electric drive device 25 according to 1 extends the traction device 24 around the upper pulley 27 and forms sections 24A . 24B out, with the section 24A along the guide rail 21 to the lower pulley 28 and the section 24B from the upper pulley 27 towards the drive device 25 extends. When using the manual drive device 26 according to 4 on the other side, the traction means forms sections 24A . 24B ' from, comparing the two drive devices 25 . 26 the section 24B in the electric drive device 25 almost parallel to the section 24A runs while at the manual drive device 26 due to the position of the manual drive device 26 on the carrier plate 10 , the section 24B ' at an angle to the section 24A runs.

To ensure that the traction means 24 during operation of the adjusting device 2 not from the pulley 27 jumps, the sections need 24A . 24B respectively. 24A . 24B ' within a desired angle (ideally parallel) to the plane of rotation of the pulley called the deflection plane 27 in the pulley 27 enter. The deflection plane extends here, as in 2 and 5 can be seen, perpendicular to the deflection axis corresponding axis of rotation D of the guide roller 27 , Because of the different course of the traction device 24 However, it is not possible, the deflection of the pulley 27 be aligned so that they both for the electric drive device 25 as well as for the manual drive device 26 within the desired angle to both through the sections 24A . 24B and 24A . 24B ' spanned levels. However, this is necessary to a uniform design of the adjustment 2 either the electric drive device 25 or the manual drive device 26 to be able to use, in particular without the orientation of the pulley 27 depending on the drive device used 25 . 26 to adapt specially.

The axis of rotation D of the pulley 27 and thus the deflection plane of the deflection roller 27 is oriented such that the deflection plane, ie the plane of rotation, the deflection roller 27 the course of the traction device when using the manual drive device 26 is adapted, the deflection plane so within the desired angle to that by the traction means 24A . 24B ' spanned level. When using the manual drive device 26 run the sections 24A . 24B ' thus at an optimal angle in the pulley 27 one, so that the traction means 24 during operation of the adjusting device 2 not from the pulley 27 can jump off.

When using the electric drive device 25 according to 1 to 3 is the enema angle of the section 24B that is between the drive device 25 and the pulley 27 However, in this case, if no additional resources were used, it would not be optimal. To make sure that too the section 24B in the area of the pulley 27 within the desired angle to the deflection plane of the pulley 27 , So substantially perpendicular to the axis of rotation D, is therefore on the guide rail 21 a cable guide 3 provided in the form of a trained as a raised area guide portion over which the section 24B of the traction device 24 passes and the section 24B so deflected that it is in the area of the pulley 27 within the desired angle to the deflection plane of the pulley 27 runs. The deflecting effect of the cable guide means 3 is in particular from the top view 2 and the side view according to 3 seen.

By means of the cable guide means 3 in the form of the raised area is thus ensured that the section 24B even when using the electric drive device 25 at an optimal angle in the pulley 27 enters. Also when using the electric drive device 25 is thus ensured that the traction means 24 during operation of the adjusting device 2 not from the pulley 27 can jump off.

Since the orientation of the deflection plane with respect to the course of the traction means 24 when using the manual drive device 26 optimized, is the cable guide means 3 formed such that it only when using the electric drive device 25 on the traction means 24 acts when using the manual drive device 26 but outside the range of the traction device 24 is arranged. This results especially in a comparison of 1 and 4 , It is also conceivable to choose an opposite arrangement, in which the traction means 24 when using the manual drive device 26 with the traction means 24 cooperates when using the electric drive device 25 However not.

In principle, it is also conceivable, a further cable guide means in the region of the lower pulley 28 provide that the course of the traction device 24 also in the area of the lower pulley 28 when using the electric drive device 25 and / or using the manual drive device 26 adapted so that the traction means both when using the electric drive device 25 as well as when using the manual drive device 26 at the optimum angle, ie within the desired angle to the deflection plane of the deflection roller 28 , in the pulley 28 enters. However, as with a comparison of 1 and 4 becomes clear, the course of the between the lower pulley 28 and the drive device 25 respectively. 26 extending portion changes only to a relatively small extent (in particular, the azimuthal angle of entry between the deflection roller 28 and the drive device 25 respectively. 26 extending portion in the plane of the support plate 10 according to 1 and 4 only slightly different), is an additional cable guide means in the region of the lower pulley 28 usually not required to ensure that the traction means 24 safely on the lower pulley 28 to be led.

It is also conceivable, an additional cable guide means in the upper pulley 27 also in the course of the traction device 24 the manual drive device 26 provided. In this way, the pulleys 27 and or 28 to some extent independent of the course of the traction device 24 be aligned, for example, optimized for the spatial conditions or the course of the guide rail 21 , wherein by cable guide means in the course of the traction means 24 both for the electric drive device 25 as well as for the manual drive device 26 it is ensured that both when using the electric drive device 25 as well as when using the manual drive device 26 the traction device 24 within the desired angle to the deflection plane of the pulley 27 or the deflection roller 28 in the pulley 27 or the pulley 28 enters.

The cable guide 3 in the form of the raised area according to the embodiment in FIG 1 to 6 has another beneficial effect. As already explained above, the traction means 24 during operation of the adjusting device 2 on the rope drum 252 the electric drive device 25 wound up and unwound to the traction means 24 for driving the driver 22 to move. Such as in 2 it can be seen, takes the traction means 24 here depending on the adjustment of the adjustment 2 different positions on the rope drum 252 one. In the in 2 shown state is the traction means 24 so on the cable drum 252 to that section 24B from the bottom, the carrier plate 10 facing end of the cable drum 252 towards the pulley 27 extends. In another adjustment of the adjustment 2 becomes the section 24B but from the top, the support plate 10 opposite end of the cable drum towards the pulley 27 extend, so that depending on the adjustment of the adjustment different gradients of the section 24B result. By the rope guide means 3 between the rope drum 252 and the pulley 27 However, it is ensured that the section 24B always at the same angle in the pulley 27 enters, the course of the section 24B in the area of the pulley 27 thus independent of the adjustment of the adjustment 2 is.

The above-explained geometric relationships are in 7a . 7b and 8th once again illustrated. As from the partial sectional view according to 7a and the frontal view according to 7b it can be seen that the sections are running 24A . 24B . 24B ' in the vicinity of the pulley 27 in a plane, namely the Zugmittelebene E ', which is parallel to the plane of rotation of the pulley 27 , referred to as deflection E, runs. The Zugmittelebene E 'thus extends perpendicular to the axis of rotation D of the guide roller 27 so that ensures the sections 24A . 24B . 24B ' at an optimal angle in the pulley 27 run in and the traction means 24 during operation of the adjusting device 2 not from the pulley 27 can jump. In the area of the section 24B Here is the cable guide 3 arranged that the section 24B so deflected that it is in the area of the pulley 27 runs parallel to the deflection plane E.

During operation of the adjusting device 2 becomes, as in the partial sectional view according to 8th is shown, the pulley 27 in a loading direction F (see also 1 and 4 ) by the traction transferring traction means 24 loaded.

To guide the traction device 24 is at the pulley 27 a guide groove 271 formed, in which the traction means 24 to be led. The guide groove 271 has a tolerance opening angle β perpendicular to the deflection plane E, in whose area the traction means 24 safely on the pulley 27 to be led. Is the traction device running? 24 at an oblique angle, ie outside the range of the tolerance opening angle β, in the deflection roller 27 a, so a leadership can not be guaranteed and there is a risk that the traction means 24 from the pulley 27 jump off.

In addition, it must also be ensured that at a maximum load, especially when applying a very large force when operating the manual drive device 26 by a vehicle occupant, the traction means 24 on the pulley 27 to be led. For this purpose, the deflection roller 27 and whose rotatable mounting dimensioned such that even with a maximum loading force in the loading direction F, the traction means 24 safely within the tolerance opening angle β runs and thus a secure guidance of the traction means 24 on the pulley 27 is guaranteed for all loading conditions. Optionally, the axis of rotation D in the in 8th shown normal position slightly against the loading direction F be inclined. The tilting against the loading direction F and the dimensioning, in particular the rigidity of the axis of rotation of the deflection roller 27 are hereby advantageously matched to each other, so that the traction means 24 regardless of the load does not reach outside the range of the tolerance opening angle β and the safe guidance of the traction device 24 on the pulley 27 is guaranteed.

The Invention is not to those described above and in the Figures illustrated embodiments limited. Rather, the inventive idea is also in completely different types of embodiments applicable. in particular, the use of the cable guide means according to the invention not necessarily limited to an application for power windows in vehicle doors, but can also be used with other adjustment devices by pulleys Use, be used. Conceivable, for example Adjustment for adjusting a sunroof, a trunk cover or a sunblind in a motor vehicle.
