Device for connecting the fixing region of a guide rail to the door frame of a vehicle door

p0001The invention relates to a device for connecting the fastening region of a guide rail to the door body of a vehicle door.

p0002From the <patcit id="pcit0001" dnum="DE19611074A1"><text>DE 196 11 074 A1</text></patcit> There is known a frameless vehicle door with a cable winch adjustable transversely to the plane of the window, the guide rails of which are connected in their upper fastening region to the door body, this region being sufficiently elastic that the setting range can be easily compensated for by a few angular degrees. In the lower fastening region of the guide rail, an adjusting and fastening angle is provided which has a longitudinal hole which defines the setting range of the guide rail transversely to the plane of the disc. By means of a screw connection, the position of the guide rail is fixed after the adjustment has been made. In doing so, the holding bracket is pulled firmly against the door body.

p0003However, in the event that there is a gap between the fastening angle of the guide rail and the associated turret-fixing point, the arched guide rail is correspondingly stretched, as a result of which the trigger radius for the window pane is increased. In the other case, when the fastening angle rises under tension on the turret-side fastening point, there is an increased curvature of the guide rail, which reduces the take-off radius. In both cases, unacceptable changes in the disk travel can occur, which leads in particular to increased displacement friction.

p0004Although the described disadvantages can be avoided by avoiding production and assembly tolerances, this considerably increases the production costs.

p0005From the <patcit id="pcit0002" dnum="EP0626283A1"><text>EP 0 626 283 A1</text></patcit> A vehicle door with a door body is known in which at least one guide rail is arranged which is connected at its one end to a mounting bracket and is held in position on the door body. The fastening angle cooperates with a retaining bracket fastened to the door body and a securing plate which receives a foot portion of the overlying mounting bracket in a rotationally fixed manner and is displaceably guided on an underlying supporting surface of the holding bracket in the longitudinal direction of the vehicle. On the securing plate are provided two spaced-apart, longitudinally extending, downwardly directed guide webs which cooperate with lateral edge sections of the bearing surface of the holding block and fix the securing plate in the transverse direction of the turbo body.

p0006The adjustment and fastening of the guide rail in the X and Y directions is effected by means of a nut provided at the foot portion of the mounting bracket into which the fastening screw can be screwed from below, recesses on the holding bracket and the securing plate being substantially larger than the outer diameter of the fastening screw. However, the movably arranged fastening screw is difficult to locate from the outer boundary surface of the turbo body since it is arranged in a region which can not be seen. Furthermore, a holding bracket, which is additionally to be provided in the door body, is required, which increases the mounting effort and takes account of further tolerances.

p0007From the <patcit id="pcit0003" dnum="US4965942A"><text>US-A-4,965,942</text></patcit> A window lifter is known whose guide rail can be pivoted about an axis of rotation arranged in the region of the door brace and can be adjusted in the direction of the vehicle transverse axis or Y axis by means of an adjustment device which is arranged in the region of the door body and is accessible from outside the door handle body so as to allow the fully extended window pane to be flush with a door Upper door or car body seal. In the case of the<patcit id="pcit0004" dnum="WO9816709A"><text>WO 98/16709</text></patcit> The adjustment in the direction of the Y axis is additionally limited by an elongated hole which extends transversely to the plane of the window pane.

p0008One from the <patcit id="pcit0005" dnum="DE4435008A1"><text>DE 44 35 008 A1</text></patcit> Has a guide rail, which extends inside a turbo body, of the window regulator arrangement, which can be pivoted about an upper pivot point in the transverse direction of the vehicle and can be fixed by means of the adjusting device engaging in the lower region of the guide rail in such a position that the edge region of the door window pane bears against an adjoining sealing body under prestress . In order to adjust the door window without dismantling the door inner panel, the guide rail can be adjusted with its lower end in the transverse direction to the door window pane in a sliding guide and can be fixed by means of fastening elements which are accessible from the underside of the door leaf body.

p0009SUMMARY OF THE INVENTION The object of the present invention is to provide a device of the type mentioned at the outset which ensures a simple and tension-free mounting of the guide rail in the door body of a vehicle door also taking account of large tolerances with adjustment and fastening of the guide rail accessible from the outside of the door handle For different vehicle types and does not require any additional parts to be permanently connected to the door body of a vehicle door.

p0010In a first variant, this task is solved according to the invention by a guide part which can be inserted into the outer boundary surface of the turbo body and is connectable to the latter and which receives the fastening means and the fastening region of the guide rail.

p0011This first solution variant ensures a simple mounting of the guide rail in the door body of a vehicle door with adjustment and fastening of the guide rail which is accessible from outside the door handle without additional parts to be permanently connected to the door body of a vehicle door, a tension-free mounting of the guide rail also taking into account large tolerances and a universal one Applicability for different vehicle types.

p0012The first solution variant permits pre-assembly of the fastening region of the guide rail with a guide part serving for the connection between the guide rail and the door body of the vehicle door, and thus the provision of a mounting unit which enables rapid and simple assembly at the location of the connection of the guide rail to the door body of a vehicle door. In order to connect the fastening region of the guide rail to the outer limiting surface of the turbo body, the prerequisite and basis for a self-adjusting adjustment of the guide rail without twisting or tensioning forces acting on the guide rail and thus a tension-free connection of the guide rail with the door body of the vehicle door. This tension-free connection is also obtained when the fastening means is actuated for fixing the guide rail to the door body, since the guide part is intended and suitable for directing the tensile forces and possibly occurring torques directly into the door body without the guide rail thereby being subjected to stress.

p0013For the adjustability of the guide rail in the Y direction of the vehicle, the fastening region of the guide rail is adjustable in the direction of the vehicle transverse axis (Y axis) within the guide part.

p0014If necessary, and depending on the location of the guide part, the guide part can be adjusted in the direction of the longitudinal axis of the vehicle (X-axis) in relation to the outer limiting surface of the turbo body and thus either compensate in the direction of the X axis or form a fixed stop in the X direction The guide part at the fastening region of the guide rail can preferably be pre-positively pre-positioned and at least at least a part of the fastening means is positively received so that a simple assembly during the production of the pre-assembly unit of the guide rail and guide part is made possible which makes possible a suitable presetting or a basic adjustment such that a more adequate, Tolerance compensation in the direction of the X-axis as well as in the direction of the Y-axis.

p0015Due to the particularly form-fitting reception at least of a part of the fastening means, a secure and twist-proof arrangement of the fastening means for securing the guide rail to the door body of a vehicle door is ensured. This also eliminates the necessity of welding a fastening means to the fastening region of a guide rail or the door body.

p0016Preferably, the guide part formed as a plastic mold part in the manner of a cassette is of a two-part construction and has a cover which can be connected to a base plate and which are connected to one another by means of a hinge, preferably a film hinge, between which a part of the fastening means is positively mounted and a part of the fastening area of ​​the fastening element is connected, Guide rail is arranged so as to be adjustable perpendicularly to the plane of the vehicle door (Y-axis).

p0017The cover member is provided with a base plate which is connected to a base plate by means of a hinge, preferably by means of a film hinge, and a part of the fastening region of the guide rail is arranged so as to be adjustable perpendicularly to the plane of the vehicle door (Y axis) , The guide part is given the form of a cassette which guides the guide rail over its setting path, so that the guide can be designed exactly to the rail turning point. The formation of the guide part as a plastic molding allows a simple production, for example by injection molding and a simple preliminary and final assembly, since the fastening means and the fastening region of the guide rail can only be inserted into the hinged guide part and the guide part must be closed by connecting the cover to the base plate , So that in this state it can be preassembled at the mounting area of ​​the guide rail and can be delivered for final assembly in a vehicle door.

p0018In a preferred embodiment, the guide part has a convex stop directed toward a lateral edge of the fastening region of the guide rail.

p0019The arrangement of a convex stop on the guide part allows the fastening region of the guide rail to assume a position automatically in which no torque acts on the guide rail, ie, no twisting of the guide rail can take place.

p0020The connection between the base plate and the cover of the guide part advantageously takes place by means of form-fitting and connecting elements, a form-fitting element protruding from a raised surface of the cover and engaging with an opening of the base plate adapted to the cross-sectional shape of the form-closing element while the guide part is closed Of the cover and, when the guide part is closed, engages in a closing opening of the base plate of the guide part for connecting the cover and the base plate.

p0021In order to be able to position the guide rail in a nominal position without aids, the guide part has a pre-adjusting element, which can be positively connected to the fastening region of the guide rail and consists of a detent element which is connected to the cover or the base plate of the guide part and which engages positively with a counter-detent element Of the fastening region of the guide rail. Due to the special shaping of the pre-setting element, an easy release of the connection of the guide part to the fastening region of the guide rail is ensured.

p0022In order to connect the guide part to the outer limiting surface of the turret body, fastening clips which engage in slots which extend parallel to the X axis and which correspond to the adjustment in the direction of the X axis project from the base plate of the guide part.

p0023The fastening clips permit positioning and temporary fastening of the guide part to the outer boundary surface of the door body, and thus ensure that the guide rail is prevented from turning when the torque is applied to the fastening means since a torque is introduced directly into the door body via the guide part and the fastening clips, Of the guide rail is prevented.

p0024Furthermore, the length of the slots provided for receiving the fastening clips can be varied in the outer boundary surface of the turbo body and thus either effect a fixing of the guide part in the direction of the X axis or allow compensation in the X direction.

p0025In particular, the fastening means can consist of a fastening screw which is connected to the guide part and a fastening nut which can be screwed onto the thread of the fastening screw from the outer side of the outer boundary surface of the door body, the head of the fastening screw being positively inserted into a screw head receptacle of the cover of the guide part.

p0026The guide part thus carries the fastening screw in the preassembled state and, when tightening the fastening means, for example by screwing a fastening nut onto the fastening screw, prevents the fastening screw from rotating without the fastening screw being otherwise secured, for example by welding the screw head. This allows easy insertion of the fastening screw into the guide part without additional fastening measures.

p0027For easy adjustment of the guide rail, an adjusting lever is provided which protrudes from the fastening region of the guide rail, engages through an opening provided in the outer limiting surface of the door handle body and can be operated from outside the door handle body.

p0028The guide rail or the fastening region of the guide rail or a fastening element connected to the guide rail and the guide part with the fastening means inserted therein preferably form a preassembled unit which can be delivered to a mounting location and inserted into a vehicle door and connected in a simple manner to the door body .

p0029In a second variant, according to the invention, the projecting task position is achieved by means of a guide part which is preassembled at the fastening region of the guide rail and can be connected to the turret body and accommodates a first part of the multipart fastener, a device for aligning the fastening region of the guide rail to the guide part and the turbo body at least in the direction of the transverse axis of the vehicle (Y-axis) and a second part of the fastening means for producing a clamping connection between the fastening region of the guide rail and the door body.

p0030This solution variant also ensures a simple and tension-free mounting of the guide rail in the door body of a vehicle door even taking into account large tolerances with adjustment and fastening of the guide rail which is variable from the outside of the door handle and can be reproduced or changed in the transverse direction of the vehicle and requires no universal use for different vehicle types Additional parts to be permanently connected to the door body of a vehicle door.

p0031Due to the possibility of pre-assembling the guide part at the fastening area of ​​the guide rail, the guide part is secured to the guide rail together with a part of the fastening means and thus delivered together with the window lifter as a unit to the mounting location. During assembly, the guide part pre-mounted on the mounting area of ​​the guide rail is used both as an adjusting gauge and positioning aid and also for the non-detachment of a part of the fastening means, so that the adjustment of the guide rail can be varied and reproduced at any time by the door body for an exact removal of the window pane in the vehicle transverse direction And thus securing an easy and safe assembly over a region which can not be inserted directly. Since the guide part preassembled at the fastening region of the guide rail can be connected to the turret body, the connecting forces occurring during the connection between the fastening region of the guide rail and the turquoise body are not transmitted to the guide rail but are directly introduced into the door body and thus into the motor vehicle door and thus a secure clamping connection Between the guide rail and the door body after alignment of the guide rail in the transverse direction of the vehicle.

p0032In order to further simplify the manufacture and assembly of the guide part, the guide part is designed as a single part and is positively connected on the side of the fastening area of ​​the guide rail remote from the door body to the fastening area of ​​the guide rail.

p0033The one-piece design of the guide part provides the prerequisite for the guide part to be produced from any material, but preferably from plastic, and no connecting elements, for example in the form of film hinges or the like, as in the case of a multi-part guide part. This also provides the prerequisite for a greater freedom of design, so that the guide part can be provided with a glass fiber reinforcement as required.

p0034The positive-locking connection of the guide part with the fastening region of the guide rail on the side of the guide rail facing away from the door body ensures that the cladding surfaces of the fastening region and the turbo body lie directly against one another and are non-positively connected to one another.

p0035The one-part design of the guide part and its form-locking connection with the fastening region of the guide rail also makes it possible to produce a guide part for different shapes and thicknesses of guide rails or their fastening regions since the form-fitting receiving can be provided with great play Connection of the guide rail with the door body of the vehicle door.

p0036An advantageous embodiment of the solution according to the invention is characterized in that a part of the fastening means is inserted through a slot opening extending in the direction of the vehicle transverse axis or Y axis of the vehicle in the fastening region of the guide rail.

p0037The slot opening provided in the fastening area of ​​the guide rail makes it easy to adjust the guide rail in the vehicle transverse direction or in the Y direction of the vehicle, whereby the pre-positioning of the guide part at the fastening area of ​​the guide rail and its connection to the door handle allows easy attachment of the fastening means. In this case, the part of the multi-part fastening means arranged in the guide part can be inserted through the slot opening of the fastening region and through a corresponding opening in the door body or inserted from outside the door body through the opening in the door body and the slot opening in the fastening region of the guide rail and with the part of the multi-part fastener arranged in the guide part Multi-part fastener.

p0038Preferably, the fastening region of the guide rail has a bearing surface and edge regions which are angled off from the bearing surface and run parallel to the slot opening, in order to grip the bracket-shaped pins of the guide part which can be inserted into positioning openings of the handle body.

p0039The edge regions, which are angled from the contact surface and run parallel to the slot opening, of the fastening region of the guide rail permit easy adjustment of the fastening region against the guide part and thus a slight alignment of the guide rail for a tension-free extraction of the window pane. The studs of the guide part which can be inserted around the angled edge regions and which can be inserted into positioning openings of the door body ensure, on the one hand, the positive connection of the guide part with the fastening region of the guide rail and, on the other hand, a positive connection of the guide part with the door body of the vehicle door before alignment of the guide rail with subsequent non-positive connection Connecting the mounting area of ​​the guide rail to the door body of the vehicle door.

p0040The bracket-shaped pegs of the guide part engaging in the door openings of the turret body securely prevent the guide part from turning during the actuation of the fastening means for the non-positive connection of the fastening region of the guide rail to the turbo body of the vehicle door and for prepositioning and pre-fixing the guide rail to the door body of the vehicle door.

p0041In the case of a double-stranded window lifter, automatic X compensation is ensured during the assembly phase. In this case, the bracket-shaped pins of the guide part connected to the one guide rail positively engage in the positioning openings of the door handle body, while the bracket-shaped pins of the guide part which is connected to the other guide rail of the double-stranded cable window lifter engage with play in the positioning openings of the turbo body extended at least in the X direction, In conjunction with a slot opening in the fastening area of ​​the guide rail, which is wider than the part of the fastening means inserted through the slot opening, ensures an automatic tolerance compensation in the longitudinal or X-direction of the vehicle.

p0042In order to simplify the adjustment of the guide rail in the Y direction of the vehicle after the pre-assembly of the guide part on the door body, an angled edge region of the fastening region of the guide rail has form closure elements with which mating form locking elements of a tool can be brought into engagement, opening into a pot-shaped opening open towards the tool guide to the door body Of the bracket-shaped pin of the guide part associated with the respective edge region.

p0043Thus, the adjustment of the guide rail relative to the door body of the vehicle door can be performed from outside the door handle, the cup-shaped opening in the one bracket-shaped side profile of the guide part ensuring a secure guidance of the tool embodied, for example, as a Torx screwdriver. Since the opening provided in the door body is aligned with the cup-shaped opening of the one bracket-shaped side profile of the guide part open towards the door body, the number of necessary through holes in the vehicle door is also reduced. By turning the tool and connecting the form-locking elements in the angled edge region of the fastening region of the guide rail to the counter-form locking elements of the tool, an easy and secure adjustment of the guide rail is ensured.

p0044In addition, in the other bracket-shaped side profile of the guide part, a contact bead abutting the outer edge of the angled edge region of the fastening region of the guide rail is arranged, as a result of which when the guide rail is adjusted in the Y direction of the vehicle, the attachment region of the guide rail is tilted around the abutment bead, A corresponding movement compensation of the guide rail is ensured and, on the other hand, the play between the form locking elements is reduced at the angled edge region of the fastening region of the guide rail and the counter-form closing elements of the tool. At the same time, it is ensured that the twisting forces during the actuation of the fastening means do not flow over the guide rails, which, in contrast to the prior art, thus do not have to be secured against twisting.

p0045A further advantageous embodiment of the solution according to the invention is characterized by a latching connection which engages in a nominal position of the guide part to the fastening region of the guide rail so that the guide rail can be positioned in this nominal position without auxiliary means.

p0046The latching connection consists of an opening provided in an angled edge region of the fastening region of the guide rail and of a latching hook which latches into the opening and which in particular consists of a ball head engaging in the opening of the fastening region of the guide rail. This latching can be triggered and re-engaged according to a further feature for the settings on the vehicle.

p0047The adjustment path via the slot opening in the fastening area of ​​the guide rail and the locking opening for the nominal setting are defined on the guide rail and not on the guide part so that the guide part is not vehicle-related and can therefore be used for different vehicle types.

p0048The fastening means preferably consists of the connection of a fastening screw with a fastening nut, wherein the guide part receives the fastening screw or fastening nut securely both in the direction of rotation and in the axial direction.

p0049This ensures the captive retention of a part of the fastening means in the guide part, and a counter bearing is ensured during the tightening of the fastening means for the non-positive connection between the fastening region of the guide rail and the door body of the vehicle door.

p0051The <figref idrefs="f0001">1 to 3</figref> In different partial sectional views, between the fastening region 10 of a guide rail 1 and an outer boundary surface 20, for example a door sill or turquoise, of a turquoise body 2 additionally show the alignment of the parts to be connected by means of a guide part 3a, Axes of a vehicle of which the X axis corresponds to the vehicle longitudinal direction, the Y axis corresponds to the vehicle transverse direction, and the Z axis corresponds to the vehicle axle axis.

p0052<figref idrefs="f0001">FIG</figref> Shows a cross-section through the connecting region with a turbo body 20 of a turquoise body 2 designed as a door inner panel, on which the fastening region 10 of a guide rail 1 is fixed, but is connected displaceably to the turquoise body 20 in the Y direction. Positions A and B show the different end positions of the fastening region 10 of the guide rail 1, which consists of a fastening angle connected to the guide rail or of an angled end of the guide rail 1.

p0053The connection between the fastening region 10 and the door body 20 is effected by means of the device shown in FIGS <figref idrefs="f0002 f0003 f0004">FIGS. 4 to 6</figref> Which consists of a base plate 4 arranged in the assembled state between the fastening region 10 and the turquoise body 20, and a cover 5 which is connected to the base plate 4 and rests with its inner surface against the fastening region 10. The cover 5 of the guide part 3a has a screw head receptacle 50, which receives the fastening screw head 63 in a form-fitting and non-rotating manner.

p0054The guide part 3a receives the fastening region 10 of the guide rail 1 between its base plate 4 and its cover 5 and is pre-mounted on the door body 20 via fastening clips 41 to 44. After the automatic alignment of the guide rail 1 or after the additional manual alignment of the guide rail 1 by means of an adjustment lever 17, which is offset from the fastening region 10 and projects through an opening in the door body 20 and can therefore be operated from outside the door handle 2, becomes the final connection of the guide rail 1 with the door body 2 by means of a fastening means 6 which is inserted through a long hole 18 in the fastening region 10, a corresponding opening in the guide part 3a and an opening in the door body 20. The fastening means 6 consists according to FIG <figref idrefs="f0001">FIG</figref> From a fastening screw 60, the fastening screw head 63 of which in the guide part 3a according to FIG <figref idrefs="f0002">FIG</figref> The screw thread 64 of which is screwed to a fastening nut 61 which is fitted from the outer side of the turbo body 20.

p0055<figref idrefs="f0001">FIG</figref> Shows that the guide part 3a is subjected to a low surface pressure because the pressing force generated by the fastening means 6 is transmitted via the fastening screw head 63 to the metal fastening region 10 of the guide rail 1, As a result, it is possible to produce the plastic guide part 3a composed of the cover 5 and the base plate 4 in a single molding operation.

p0056Alternatively, the cover 5 can form a continuous surface on which the fastening screw head 63 of the fastening means 6 rests, so that the fastening means 6 is completely integrated into the guide part 3. In this embodiment, it is advantageous if the support of the fastening screw head 63, if appropriate, also the entire cover 5 is provided with a glass fiber reinforcement.<figref idrefs="f0001">FIG</figref> Shows a longitudinal section through the connecting region with a lower part of the guide rail 1 and its fastening region 10 connected to the turquoise body 20 via the guide part 3a and illustrates the connection of the base plate 4 with the cover 5 of the guide part 3a via a form closure element 56 as well as an opening of the fastening region 10 and engaging with the base plate 4.

p0057A detent element 51, which engages into a recess or opening 19 in the fastening region 10 of the guide rail 1, serves to pre-position the guide part 3a on the fastening region 10 of the guide rail 1. With the aid of the latching element 51, the guide part 3a provides a standard position, which serves for the presetting.

p0058<figref idrefs="f0001">FIG</figref> Shows a plan view of the connecting region with the fastening region 10 of the guide rail 1, the cover 5 of the guide part 3a and the openings or slots 21 to 25 provided in the door body 20, and illustrates the adjustability of the guide rail 1 in the Y direction by the arrangement of an elongated hole 18 In the fastening region 10 as well as an opening 25 in the door body, through which the adjusting lever 17 is inserted. The fastening clips 41 to 44 protruding from the outer side of the base plate 4 of the guide part 3a are inserted into the slots 21 to 24 of the turbo carrier 20, two slots, namely the slots 21, 22, being longer than the width of the associated fastening clips 21, So that an X-balance becomes possible. On the other hand, the fastening clips 43, 44 are inserted into slots 23, 24, the length of which corresponds to the width of the fastening clips 43, 44, so that these fastening clips 43, 44 are fixed in the X direction.

p0059By means of the fastening clips 41 to 44 inserted into the slots 21 to 24, a transfer of a torque to the guide rail 1 during the tightening of the fastening means 6 is prevented, since the guide part 3a is pre-consolidated by means of the fastening clips 41 to 44 on the door body 20 and thus when the fastening means is secured 6 can be derived in the door body 20.

p0060The representation of the fastening clips 41 to 44 and slots 21 to 24 according to FIG <figref idrefs="f0001">FIG</figref> Is to be understood as either slots 21 to 24 adapted to the width of the fastening clips 41 to 44 are provided and thus no X compensation is possible or slots 21 to 24 are provided whose length is greater than the width of the associated fastening clips 21 to 24, So that an X-balance is made possible. This however illustrates that the introduction part is suitable for the application of a guide rail in the region of the A-pillar as well as a guide rail in the region of the B-pillar of a vehicle.

p0061By means of this form of connection of the guide part 3a to the outer boundary surface 20 of the turbo body 2, it is ensured that the guide part 3a in the case of a double-stranded cable window lifter with two guide rails is used for fastening the guide rail assigned to the A-column as well as for fastening the guide rail assigned to the B-column Guide rail can be used. The orientation of the fastening clips allows an X-balance in the guide rail associated with the A-pillar by the associated slots being wider than the fastening clips. On the other hand, by means of a width of the slots adapted to the width of the fastening clips, a fixing of the guide part, which serves to secure the guide rail assigned to the B-column, is effected.

p0062The X-compensation of the guide rail assigned to the A-pillar is very important for a parallel withdrawal of the window pane guided over the guide rails so as to avoid slippage in the window lifter system. This X compensation is then possible when the window pane is moved downwards without the fastening means already being tightened and thus fixing the relevant guide rail to the door body. Thus, the guide rail can automatically position itself in the X and Y directions before actuation of the fastening element, whereby the fastening clips ensure that no torque is exerted on the guide rail with the consequence of a twisting of the guide rail when the fastening means is tightened after the self-positioning of the guide rail .

p0095When the two guide rails of a double-stranded cable window lifter are connected, the one guide rail, as described above with reference to FIGS <figref idrefs="f0001 f0002 f0003 f0004 f0005 f0006 f0007">Figures 1 to 9</figref> Is connected to the door body 2 while the other guide rail for automatic compensation in the direction of the vehicle longitudinal axis or X direction is connected to a guide part preassembled at the fastening area of ​​this guide rail and which engages in form holes of the door handle body 2 which are in the X direction as long holes So that the pins of the guide part can perform a movement compensation in the X-direction. Likewise, the slot opening 12 in the mounting area of ​​this guide rail is wider than the mounting screw shank so that the mounting area can also perform a compensating movement in the X-direction.

p0096By inserting the guide parts preassembled on the fastening regions of the two guide rails into the form holes or in the X direction of the turbo body, an automatic compensation of tolerances in the X direction takes place, while the fine adjustment takes place in the Y direction in the manner described above by means of a tool 8 is performed.

p0097The guide part 3b can therefore be used both for a guide rail arranged on the A-pillar as well as for a guide rail arranged on the B-pillar. The orientation of the bracket-shaped pins 31, 32 of the guide part 3b makes possible an X-compensation in the case of the guide rail associated with the A-column, for example, when the positioning openings 27, 28 in the door body 2 are wider in the X direction than the bracket-shaped pins 31, 32 of the guide part 3b are. This X-balance is very important and leads to an exact parallelism of the two guide rails of a double-stranded cable window lifter, so that a stiffness is prevented in each window lifter system.

p0098The X compensation is then possible when the window pane is driven downwards without the fastening means having a fixed connection between the fastening region of the guide rail and the door body of the vehicle door on the guide rail assigned to the A-pillar. Thus, the guide rail automatically positions itself in the X and Y directions of the vehicle.
