Abstract
Description
Technical Field
[0001] The invention relates to a device for a frameless vehicle door, comprising a support, the support having a guide rail for a window lifter fastened to the support, and an adjustment device arranged between the support and the guide rail for tilting the guide rail in an adjustment direction oriented perpendicularly to the support. The invention also relates to a door module and a frameless vehicle door having such a device. Background Art
[0002] Here and below, a "frameless door" is understood to be a door without a window frame for the (window) glass, in which the glass is recessed in a door seal on the body side. Such frameless doors are used, for example, in convertibles.
[0003] Functional components of vehicle doors, such as window regulators, drives, side airbag modules, loudspeakers, operating units or similar functional components, are usually pre-assembled on a unit carrier of a door module (also referred to as a door module carrier or carrier plate). The door module or unit carrier is installed in a door recess of a door frame or door frame of the vehicle door.
[0004] For example, a window lifter for a vehicle door is implemented with a cable traction mechanism for raising and lowering a (window) glass. In such a window lifter, the glass is guided along at least one guide rail by means of a carrier or a rail slide. The cable traction mechanism typically has a cable traction member, which is guided on the one hand in a cable drum that winds up and unwinds the cable traction member, and on the other hand is guided to the carrier or the rail slide after one or more deflections and fixed there.
[0005] When used in frameless vehicle doors, it can happen that due to tolerances caused by production, the glass, for example, escapes from the door seal and a gap is formed, or the glass is pressed excessively against the door seal, so that binding and increased wear occur due to increased friction.
[0006] In order to compensate for these assembly or manufacturing tolerances, it is therefore usually necessary to pivot or tilt the window glass when mounted on the door in an adjustment direction perpendicular to the unit carrier (along the vehicle transverse axis Y) so that the window glass is prestressed in the desired manner relative to the door seal in this direction.
[0007] In order to achieve such tolerance compensation, it is possible, for example, to use a double threaded bolt with axial accessibility as an adjusting element. The double threaded bolt can be screwed into the guide rail on the one hand and into the unit carrier on the other hand, so that when the double threaded bolt is turned, these components are moved toward each other or away from each other, so that the inclination of the guide rail relative to the door module or the unit carrier can be adjusted.
[0008] In order to turn the double thread bolt, a (adjusting) tool, such as a screwdriver, is typically provided, wherein "axial accessibility" is understood in this respect as the tool being guided toward the double thread bolt in the axial direction (i.e., longitudinal direction) of the double thread bolt and embedded in the tool receiving portion at the end of the double thread bolt. Therefore, in this case, the adjustment direction and the approach direction of the tool are oriented parallel to each other. This means that the approach direction of the tool is usually oriented perpendicular to the unit carrier, i.e., oriented in the transverse direction Y of the vehicle. Since tolerance compensation is performed in the vehicle door in the installed state, it is necessary to remove the door interior panel for tolerance compensation, which disadvantageously increases the cost for assembling the vehicle door. An additional disadvantage is the need to use a special tool (combination tool, which is also called a "holding drive wrench") to loosen, hold and rotate the double thread bolt with a nut.
[0009] An approach direction which is oriented at right angles or perpendicularly to the adjustment direction of the tool (transverse vehicle direction Y) can usually only be realized with the aid of large gear mechanisms, which disadvantageously makes the use of an integrated solution on the door module difficult. Summary of the invention
[0010] The object of the present invention is to specify a particularly suitable device for a frameless vehicle door. In particular, a tolerance compensation method with a simple design and compact construction space for adjusting the glass inclination of a window glass in a vehicle door should be specified. The object of the present invention is also to specify a particularly suitable door module and a particularly suitable frameless vehicle door.
[0011] According to the invention, this object is achieved with respect to the device by means of the features of claim 1, with respect to the door module by means of the features of claim 13, and with respect to the vehicle door by means of the features of claim 14. Advantageous embodiments and developments of the invention are subject matter of the dependent claims. The advantages and embodiments listed with respect to the device can also be transferred to a certain extent to the door module and / or the vehicle door, and vice versa.
[0012] Here and below, the conjunction “and / or” is to be understood to mean that the features connected by means of this conjunction may not only be configured together but also as alternatives to one another.
[0013] The device according to the invention is designed and adapted and configured for frameless vehicle doors. The device has a stationary or static support on which a guide rail for a window lifter is pre-mounted. For example, the guide rail is part of a cable window lifter for a vehicle door. The support is, for example, a unit carrier (carrier plate) of a door module that is mounted or can be mounted in the vehicle door or a door frame of the vehicle door.
[0014] The device also has an adjustment device. The adjustment device is arranged and configured to deflect or pivot or bend or tilt the guide rail along an adjustment direction oriented obliquely relative to the support. In other words, the spacing or clear width between the guide rail and the support can be adjusted at least in sections by means of the adjustment device.
[0015] Here and below, “obliquely” is understood to mean in particular an essentially vertical orientation, ie for example 90°±45°, in particular 90°±30°, preferably 90°±15°, particularly preferably 90°±5°.
[0016] The adjustment device thus makes it possible to compensate for tolerances in the inclination of the glass caused by manufacturing and / or assembly, so that the window glass guided by the window lifter can be pretensioned in the desired manner relative to the door seal of the vehicle door in the adjustment direction. According to the invention, it is not the window glass that is deflected or swung to compensate for the tolerances, but the guide rail on which the window glass is guided by means of a driver or a rail slide. The glass inclination of the window glass guided by the window lifter is thus indirectly set or adjusted by tilting the guide rail relative to the support. As a result, when adjusting the guide rail, it is possible to achieve a uniform and smooth passage of the window glass through the door window sill groove of the vehicle door along the groove.
[0017] The adjusting device is arranged between the guide rail and the support. In other words, the adjusting device is arranged below the guide rail, wherein this positioning results in a particularly compact arrangement of the components. The adjusting device is advantageously arranged in the upper and / or lower region of the guide rail, i.e. close to the cable deflection rollers of the guide rail.
[0018] The adjusting device can be actuated by a tool, wherein the approach direction of the tool for actuating the adjusting device is oriented obliquely with respect to the adjusting direction. For example, the approach direction is oriented substantially perpendicularly to the adjusting direction.
[0019] In the following, the description of the spatial directions is also given, in particular in the coordinate system of the motor vehicle (vehicle coordinate system), with reference to the exemplary installation of the door module in a frameless side door of the motor vehicle. The transverse axis (X axis, X direction) is oriented in the longitudinal direction of the vehicle (direction of travel), the longitudinal axis (Y axis, Y direction) is oriented in the transverse direction of the vehicle, and the vertical axis (Z axis, Z direction) is oriented at the height of the vehicle.
[0020] The support, i.e., for example, the unit carrier or the door frame, is arranged essentially in the XZ plane, wherein the longitudinal direction of the guide rails is arranged essentially along the vehicle height Z. The adjustment direction is oriented obliquely to the XZ plane, i.e., for example, essentially in the vehicle transverse direction Y, wherein the approach direction extends essentially within the XZ plane or parallel to the XZ plane.
[0021] The adjusting device has at least two adjusting parts that can move relative to each other, in the form of a threaded bolt (threaded column) oriented in the adjustment direction and at least one nut. The threaded bolt has an external thread and the nut has a corresponding internal thread, wherein the threaded bolt and the nut are in threaded engagement. In other words, the at least one nut is screwed or screwed onto the threaded bolt. By using standard components (threaded bolt, nut), an adjusting device that is particularly simple in design and inexpensive is achieved.
[0022] Here and hereinafter, “axial” or “axial direction” is understood to mean, in particular, a direction parallel (coaxial) to the longitudinal direction of the threaded bolt, that is, a direction perpendicular to the end face of the nut. The axial direction and the adjustment direction are therefore arranged essentially parallel to the vehicle transverse direction Y. Accordingly, here and hereinafter, “radial” or “radial direction” is understood to mean, in particular, a direction oriented perpendicularly (transversely) to the threaded bolt along the radius of the nut.
[0023] One of the adjusting components, i.e. either a threaded bolt or at least one nut, is fixed to the guide rail or support in a rotationally fixed manner. In other words, the adjusting component is engaged with the guide rail / support in a rotationally fixed manner. The other adjusting component is supported in a rotatable or rotatable manner. The adjusting component supported in a rotatable manner has a drive profile here, by means of which the adjusting component can be driven directly or indirectly by a tool, i.e., can be rotated, so that the axial relative adjustment of these adjusting components relative to each other is performed along the adjustment direction, and thus the adjusting device is operated. At least in the case of tool embedding, an angular transmission mechanism, in particular a 90° change-of-direction transmission mechanism, such as a bevel gear transmission mechanism, is formed by the tool and the adjusting device. By driving or rotating the rotatable component, the rotatable component moves relative to the fixed adjusting component due to the threaded engagement. This makes it possible to achieve a reliable and structurally simple adjustment of the adjusting device, i.e., it is possible to achieve tolerance compensation for the orientation and inclination of the window glass, and the adjusting device can be integrated into a door frame or door module. Therefore, a particularly suitable device is achieved.
[0024] Due to the compact structure of the adjusting device and its space-saving arrangement below the guide rail, a particularly space-efficient device is achieved. The adjusting device can be positioned relatively freely along the guide rail, thereby enabling additional freedom in the design and installation of the support.
[0025] By means of the adjusting device, the inclination of the track (and thus the inclination of the glass) is adjusted using a right-angle approach for driving. The approach mode or approach direction can be variably arranged in a manner that can rotate around the thread axis (adjustment direction, axial direction) of the threaded bolt, so that a particularly flexible and variable design can be achieved. In other words, the approach direction is basically arranged radially relative to the adjustment direction or the threaded bolt in the XZ plane. Therefore, the approach direction can be oriented rotationally relative to the thread axis according to the application or customer's wishes. In the conceivable implementation scheme, the approach direction is oriented substantially perpendicular to the longitudinal direction of the guide rail (i.e., substantially perpendicular to the vehicle height direction Z). Therefore, the adjusting device is, for example, arranged and established for manipulation using a tool along the X direction. The tool is approached here in particular from the end side of the door lock side of the vehicle door.
[0026] The approach direction is thus oriented, for example, substantially in the X direction. The expression “substantially in a direction” is to be understood here and hereinafter to mean in particular “in this direction” ±45°, preferably ±30°, particularly preferably ±5°.
[0027] In an advantageous development, the nut is a rotatably supported adjustment element that can be driven by a tool. The drive profile is formed on the nut at the end. The threaded bolt is mounted on or in the guide rail in a rotationally fixed manner and protrudes axially, for example, from the lower side of the guide rail facing the support. A particularly compact design is achieved by positioning the bolt "underneath" the guide rail and having an interface facing the support. The drive profile is designed, for example, as a toothing, for example as a bevel gear toothing.
[0028] Preferably, the nut is accommodated in a relatively fixed interface. In a suitable design, the nut is arranged radially in a rib-shaped receiving portion and is held axially in a positive locking manner. The receiving portion can be part of the support, in particular a part of the unit carrier or a door frame.
[0029] A "positive fit" or a "positive connection" between at least two parts connected to one another is understood here and hereinafter to mean in particular that the parts connected to one another are held together at least in one direction by direct interlocking of the contours of the parts themselves or by indirect interlocking via additional connecting parts. The "prevention" of relative movement in this direction is therefore due to the shape.
[0030] Therefore, the firmly mounted threaded bolt is installed in the guide rail and supported in a drivable nut, which is received in a positive locking manner in the receptacle. By turning or driving the nut, the threaded bolt is moved and the guide rail is driven along with it, so that the positioning or inclination of the guide rail in the adjustment direction (axial direction, vehicle transverse direction Y) is changed.
[0031] The receiving portion has, for example, an axial through-opening or a depression (blind hole) through which the threaded bolt can be guided in sections or into which it enters. The axial engagement of the threaded bolt that can be achieved thereby enables a greater adjustment stroke for the adjusting device and thus a greater play space for tolerance compensation.
[0032] In one conceivable construction, a support shell, referred to as a retaining bend, is provided for axially positively retaining the nut. In particular, the support shell is fastened to the support and / or the guide rail in a detachable manner, for example by screws, and at least partially overlaps the receptacle. Alternatively, it is also conceivable, for example, that the receptacle is part of the support shell. The support shell thus axially clamps the nut with the support. Preferably, the support shell also has a tool guide for a tool oriented in the approach direction, which leads into the receptacle. For example, the tool guide is formed into the support shell as a groove or a rib. Thus, even when the support shell is assembled, access to the drive contour is ensured via the tool guide.
[0033] In an alternative development, the adjustment device is designed in the manner of a turnbuckle. In this development, the threaded bolt is a rotatably supported adjustment element. More preferably, two nuts are provided as stationary adjustment elements, wherein one nut is fixed to the guide rail and the other nut is fixed to the unit carrier.
[0034] In a suitable construction scheme, the threaded bolt is implemented as a double-threaded rod, which has two external threads at the opposite rod ends. Preferably, the external threads are implemented in opposite directions. In other words, one of the external threads is implemented as a right-handed thread and the other external thread is implemented as a left-handed thread. Here, one of the nuts is screwed onto the right-handed thread and the left-handed thread respectively. The drive profile is arranged in the form of a drive toothing between the external threads, that is, approximately in the middle of the threaded bolt or on half of the axial height. The radial drive toothing is implemented here to form a straight toothing in the axial direction. By driving the threaded bolt with the central drive toothing, the guide rail and the unit carrier are moved away from or close to each other.
[0035] In an advantageous embodiment, the drive profile or the drive toothing meshes with a screw element that can be rotated by a tool. The screw element is oriented in the approach direction, that is, perpendicular to the threaded bolt. The rotatably supported screw element forms a worm gear with the drive profile. This means that the threaded bolt can be driven or driven only indirectly by the tool. The screw element enables particularly fine adjustments or tolerance compensation in the case of tension screw adjustment devices.
[0036] In a further alternative development, the threaded bolt is rotatably mounted on the carrier, wherein a nut is connected to the guide rail in a rotationally fixed manner and performs an axial adjustment when the threaded bolt is threadedly rotated.
[0037] The support is substantially C-shaped or U-shaped, in particular with a right-angle bend, and has a vertical holding leg (vertical leg) and two horizontal holding legs (horizontal legs) oriented perpendicularly to the vertical legs at the opposite leg ends. The vertical legs are oriented parallel to the adjustment direction, wherein the horizontal legs are oriented parallel to the plane of the support. The legs form a substantially bow-shaped holding fixture for a threaded bolt arranged in a bowstring manner, which is rotatably supported in the horizontal leg of the support. The threaded bolt is held on the support in an axially positive manner.
[0038] In a suitable embodiment, the support is arranged spaced apart from the support via two retaining legs. The retaining legs or retaining straps are preferably integrally, i.e. integrally or integrally formed on the support, in particular on the lower horizontal leg (facing the unit carrier). The retaining legs are, for example, L-shaped, wherein the horizontal leg of the L forms the contact part or interface with the unit carrier. For example, the horizontal leg of the L is embodied as a screw strap or screw flange for fastening the support to the support by screws.
[0039] This spacing arrangement results in an intermediate space between the support and the lower horizontal leg. The threaded bolt extends at least in sections into the intermediate space thus formed. In other words, the threaded bolt passes through the lower horizontal leg at least in sections. The drive profile of the threaded bolt is arranged on the end side of the threaded bolt arranged in the intermediate space. For example, the threaded bolt has a bolt head with a shaped drive profile, for example in the form of a bevel gear tooth. The drive profile is thus positioned between the retaining legs. Therefore, at least one of the retaining legs has a through opening oriented in the approach direction at the height of the drive profile. This ensures simple and reliable access to the tool.
[0040] The door module according to the invention has an assembly carrier as a carrier plate or door module carrier and a device as described above. The assembly carrier preferably forms a mount for the device. In addition, the guide rails of the device are, for example, part of a cable window lifter, which is pre-mounted on the assembly carrier. This creates a particularly suitable door module in which the device for adjusting the inclination of the window is integrated on the assembly carrier.
[0041] The frameless door according to the invention can be, for example, a side door of a motor vehicle, in particular a convertible. The door has, for example, a door module as described above. A window lifter with a window pane is arranged on the door module. Alternatively, it is possible, for example, to install the device in the door without a door module or an assembly carrier. In this case, the door frame of the door forms the support for the device. This means that the device is fastened directly to the door frame.
[0042] The adjustability of the guide rail or the inclination of the guide rail relative to the assembly carrier allows a simple adjustment for compensating for tolerances in the inclination of the window pane, thereby achieving a particularly suitable frameless door.

[0057] exist Figure 1 2 shows a simplified schematic diagram of a frameless vehicle door 2 with an optional door module 4. The door module 4 has an assembly carrier 6, which has an electric window lifter 8 mounted thereon as an adjustment device for a (vehicle) window pane 10. Alternatively, the window lifter 8 can also be installed without the door module 4 or the assembly carrier 6.
[0058] The window lifter 8 has an adjusting motor 12 which acts on the window pane 10 via an adjusting mechanism 14. The adjusting mechanism 14 has a guide rail 16 and a driver or rail slide 18 which is connected to the window pane 10.
[0059] In the embodiment shown, the window lifter 8 is designed as a single-guide cable window lifter. Here, in addition to the guide rail 16, the adjustment mechanism 14 also has a cable pull 20.
[0060] The adjustment motor 12 of the window lifter 8 drives the cable drum 24 of the adjustment mechanism 14 via a worm gear or spur gear 22. The traction cable of the cable traction element 20 is arranged on the cable drum 24 in such a way that when the cable drum 24 is rotated by the transmission 22, the traction cable is wound up and unwound.
[0061] An upper cable deflection roller or cable roller 26 and a lower cable roller 28 are fastened to the guide rail 16 and are arranged at opposite (track) end faces or track ends. The traction cable of the cable traction element 20 is guided around the cable rollers 26 , 28 .
[0062] When the adjustment motor 12 is actuated, the window pane 10 is moved into its (glass) position P. The window pane 10 is reversibly movable between a closed position S, which represents the highest possible position P, and an open position O, which represents the lowest possible position P. In these two positions S and O, the window pane 10 is Figure 1 In the figure, the window pane 4 is respectively indicated by dashed lines. On the contrary, the window pane 4 is shown by solid lines in the half-opened intermediate position.
[0063] In the following, the description of the spatial directions is also given in particular in the coordinate system of the motor vehicle (vehicle coordinate system) with reference to the door 2 designed as a side door. The transverse axis (X axis, X direction) is oriented in the longitudinal direction of the vehicle (driving direction), the longitudinal axis (Y axis, Y direction) is oriented in the transverse direction of the vehicle, and the vertical axis (Z axis, Z direction) is oriented at the height of the vehicle.
[0064] The assembly carrier 6 is arranged here essentially in an XZ plane, wherein the rail longitudinal direction of the guide rails 16 is arranged essentially along the height Z of the vehicle.
[0065] The door module 4 also has a device (not shown in detail) with an adjustment device 30. The adjustment device 30 is provided and configured to deflect or pivot or bend or tilt the guide rail 16 in an adjustment direction V oriented perpendicularly to the support. The adjustment direction V is oriented substantially in the Y direction or parallel to the Y direction.
[0066] In the following, we will combine Figures 2 to 6 A first exemplary embodiment of the device 30 is explained in detail. In this exemplary embodiment, the support is formed by an assembly carrier 6 and is also referred to as assembly carrier in the following.
[0067] Especially from Figure 2 and Figure 3 As can be seen in the figure, in the present embodiment, the adjusting device 30 is arranged between the guide rail 16 and the assembly carrier 6. The adjusting device 30 is arranged in the upper and / or lower region of the guide rail 16, ie in the region of the cable rollers 26 and / or 28.
[0068] The adjusting device 30 can be actuated by means of a tool 32. During adjustment or tolerance compensation, the tool 32 is brought into operative connection with the adjusting device 30 along a (tool) approach direction W. For actuating the adjusting device 30, the approach direction W of the tool 32 is arranged obliquely or perpendicularly to the adjustment direction V. In the exemplary embodiment shown, the approach direction W is arranged in particular substantially in the longitudinal direction X of the vehicle.
[0069] For example, from Figures 4 to 6 As can be seen in FIG. 1 , the adjusting device 30 of the device has in the present exemplary embodiment two adjusting parts 34 and 36 which are movable relative to each other in the form of a threaded bolt 34 oriented in an adjustment direction V and a nut 36 screwed onto the threaded bolt.
[0070] The nut 36 is rotatably supported in a rib-shaped receiving portion 38 of the unit carrier 6. The receiving portion 38 is surrounded by an axially vertically protruding edge 40, which is integrally formed on the unit carrier 6 and radially holds the nut 36 in a form-locking manner. The nut 36 has a drive contour 42 in the form of a bevel gear toothing at the upper end side facing the guide rail 16. The tool 32 has a corresponding tool contour, which can be placed in meshing engagement with the drive contour 42, so that a 90° change of direction transmission mechanism is effectively realized via the contour. This means that in the present embodiment, the adjustment device 30 can be driven directly or directly by means of the tool 32.
[0071] In order to prevent the nut 36 from axially sliding out of the receiving portion 38, a support shell 44, referred to as a retaining bent piece, is provided, which is fastened to the unit carrier 6 by means of screws in such a way that it at least partially overlaps the receiving portion 38, so that the nut 36 is axially held in a form-locking manner between the support shell 44 and the bottom of the receiving portion 38 or the unit carrier 6. The retaining bent piece 44 is Figure 5 Not shown.
[0072] In the present embodiment, the bearing shell 44 completely overlaps the nut 36. In other words, the nut 36 is covered at the end by the bearing shell 44. The bearing shell 44 has a through-opening 46 for the threaded bolt 34, which is aligned with and coaxially arranged with the receptacle 38. The bearing shell 44 also has a tool guide 48 for the tool 32, which is oriented in the approach direction W and opens into the receptacle 38. The tool guide 48 is formed into the bearing shell 44 as a groove or a rib.
[0073] A blind hole-like depression 50 is formed in the center of the receptacle 38, into which the threaded bolt 34 is at least partially embedded. The axial depth of the depression 50 is substantially equal to the axial length of the threaded bolt 34 and therefore effectively corresponds to the adjustment stroke of the adjusting device 30. In particular, during adjustment or actuation of the adjusting device 30, the bottom of the depression 50 forms a mechanical (end) stop for the end side of the threaded bolt 34.
[0074] The threaded bolt 34 is mounted on or in the guide rail 16 in a rotationally fixed manner and protrudes axially upright from the lower side of the guide rail 16 facing the unit carrier 6 in the direction of the recess 50. Therefore, the firmly mounted threaded bolt 34 is installed in the guide rail 16 and supported in a drivable nut 36, which is radially and axially positively held on the unit carrier 6. By rotating or driving the nut 36 with the help of the tool 32, the threaded bolt 34 is moved in the adjustment direction V via the interlaced and nested threads, and the guide rail 16 is driven thereby, so that the positioning or inclination of the guide rail changes in the adjustment direction V.
[0075] Figure 7 and Figure 8 A second embodiment of the device is shown in FIG. 1 and is explained in detail below. The support of the device is formed by a unit carrier 6 .
[0076] In the present embodiment, the adjusting device 30' of the device is implemented in the type of a turnbuckle. The adjusting device 30' has two nuts 36a, 36b and a threaded bolt 34' implemented as a double threaded rod. The nut 36a is connected to the guide rail 16 in a rotationally fixed manner, wherein the nut 36b is fastened to the bracket 52 in a rotationally fixed manner. The bracket 52 is connected to the unit carrier 6, for example by screws.
[0077] The support 52 has a stepped central section 54, in which the nut 36b is arranged. The central section 54 of the support 52 is therefore arranged axially spaced from the unit carrier 6, so that an intermediate space 56 is formed between the central section 54 and the unit carrier 6. The central section 54 has a through opening for the threaded bolt 34', so that the threaded bolt can be moved into the intermediate space 56 within the range of the adjustment stroke of the adjustment device 30'.
[0078] The rotatably supported threaded bolt 34' is provided with an external thread at the opposite rod ends. The external threads are provided here as left-hand and right-hand threads in opposite directions. A drive profile 58 in the form of a drive toothing is arranged between the external threads, i.e. approximately in the middle or half of the axial height of the threaded bolt 34'. The radial drive profile 58 is provided here as a straight toothing in the axial direction.
[0079] Adjacent to the threaded bolt 34', a holding contour 60 is integrally formed, i.e. in one piece or in one piece, on the unit carrier 6, which has a substantially C-shaped receptacle 62 in cross section for a screw element 64 designed as a headless screw. The holding contour 60 or the receptacle 62 is arranged such that the outer thread of the screw element 64 rotatably mounted therein engages in a snap-fitting manner with the drive contour 58. The screw element 64 here forms a worm gear with the drive contour 58.
[0080] The screw element 64 is oriented in the approach direction W, ie perpendicularly to the threaded bolt 34 ′, and has a tool receptacle at the end, for example a hexagon socket or a Torx socket, for a corresponding tool contour of the tool 32 .
[0081] A further tool holder 66 is optionally provided on the end face of the guide rail-side threaded bolt 34'. The tool holder 66 is designed here, for example, as a Torx socket. The tool holder 66 allows the adjusting device 30' or the threaded bolt 34' to be actuated in an approach direction W oriented parallel to the adjustment direction V. This allows the adjusting device 30' to be actuated or driven in the Y direction, for example, when removing an interior trim panel of the vehicle door 2.
[0082] By driving the threaded bolt 34', the guide rail 16 and the unit carrier 6 are moved away from or towards each other due to the opposite external threads. The adjusting device 30' can be driven directly or directly via the tool 32 and the tool holder 66 from the Y direction. The adjusting device 30' is also provided and configured to be driven indirectly from the X direction via the tool 32 engaged in the screw element 64.
[0083] Fig. 9A third embodiment of the device is shown, in which the support is formed by the unit carrier 6. In this embodiment, the threaded bolt 34 ″ of the adjusting device 30 is rotatably supported on the support 68, wherein the nut 36 ″ is connected to the guide rail 16 in a rotationally fixed manner and performs an axial adjustment along the threaded bolt 34 ″ when the thread is rotated.
[0084] The support 68 is substantially C-shaped or U-shaped and has a vertical holding leg (vertical leg) 70, at the opposite leg ends of which two horizontal holding legs (horizontal legs) 72 are formed and oriented perpendicularly to the vertical legs. The vertical leg 70 is oriented parallel to the adjustment direction V, wherein the horizontal leg 72 is oriented parallel to the plane (XZ) of the unit carrier 6. The legs 70 and 72 substantially form an arched holding fixture for the threaded bolt 34 ″ arranged in a bowstring manner relative to the holding fixture, which is rotatably supported in the horizontal leg 72 and is axially positively held.
[0085] The support 68 is arranged at a distance from the unit carrier 6 via two retaining legs 74. The retaining legs 74 are preferably integrally formed, i.e., in one piece or integrally formed, on the lower horizontal leg 72. The retaining legs 74 are designed, for example, in an L-shaped manner in the XY plane, wherein the horizontal leg of the L forms an abutment or interface with the unit carrier 6. For example, the horizontal leg of the L is designed here as a screw strap or screw flange for screwing the support 68 to the unit carrier 6.
[0086] Due to the spaced arrangement by means of the retaining legs 74, an intermediate space 76 is formed between the unit carrier 6 and the lower horizontal leg 72. The threaded bolt 34 ″ extends at least partially into the intermediate space 76. In other words, the threaded bolt 34 ″ passes through the lower horizontal leg 72 at least partially. The threaded bolt 34 ″ has a drive profile 78 in the form of a bevel gear toothing at the end side arranged in the intermediate space 76. The retaining legs 74 here each have a through opening 80 oriented in the approach direction W at the height of the drive profile 78.
[0087] Combined with the following Figures 10 to 12 A fourth embodiment of the device is explained in detail. In this embodiment, the adjusting device 30''' is installed in the vehicle door 2 without the unit carrier 6 or the door module 4. In particular, the adjusting device 30''' is fastened to the door frame 82. In this embodiment, the door frame 82 forms a support and is also referred to as such in the following text.
[0088] The adjusting device 30''' has a fixed threaded bolt 34''' in the adjusting direction V, the head side of which is fixed to the door frame 82. Therefore, the threaded bolt 34''' basically protrudes vertically from the door frame 82 in the Y direction. The nut 36''' is rotatably supported in a pot-shaped receiving portion 84 of the support shell 44.
[0089] The bearing shell 44 or the receiving portion 84 has a central through-opening, through which the stud of the threaded bolt 34''' passes. In addition, the bearing shell 44 has a tool guide 48 for the tool 32 oriented in the approach direction W, which opens into the receiving portion 84. The tool guide 48 is designed as a substantially truncated cone-shaped channel of the bearing shell 44.
[0090] The guide rail 16 has a rib-like retaining contour 86 which points in the direction of the door frame 82. The support shell 44 is fixed to the retaining contour 86 by means of two fastening screws 88, whereby the nut 36''' is held axially in a form-fitting manner between the receptacle 84 and the retaining contour 86. The guide rail 16 is thus indirectly fixed to the door frame 82 via the adjustment device 30'''. The guide rail 16 has a through-opening (not specifically indicated) through which the free end of the threaded bolt 34''' passes.
[0091] The nut 36''' has a shank section 90 extending along the threaded bolt 36''' and a head section 92 placed radially and positively in the receptacle 84. A drive contour 92 for the tool 32 is introduced on the head section 92 at the end facing the guide rail 16, for example in the form of a bevel gear toothing.
[0092] By inserting the tool 32 into the drive profile 92 to rotate or drive the nut 36''', the nut 36''' moves along the threaded bolt 34''' in the adjustment direction V via the interlaced and nested threads, and drives the guide rail 16 due to the connection method of the support shell 44, so that the positioning or inclination of the guide rail changes along the adjustment direction V.
[0093] The claimed invention is not limited to the above-described embodiments. On the contrary, other variants of the invention can be derived by a person skilled in the art within the scope of the disclosed claims without departing from the subject matter of the invention. In addition, in particular, all individual features described in conjunction with different embodiments can also be combined with each other in other ways within the scope of the disclosed claims without departing from the subject matter of the invention.
