DETAILED DESCRIPTION OF THE INVENTION

[0063] Referring now in detail to the figures of the drawings, in which parts and sizes which correspond to one another are always provided with the same reference numerals, and first, particularly, to FIG. 1 thereof, there is seen a simplified and diagrammatic view of an electrical window regulator 2 as an actuating device for a (vehicle) windowpane 4 of a motor vehicle.

[0064] The window regulator 2 has an actuating motor 6 which acts by using an actuating mechanism 8 on the windowpane 4. The actuating mechanism 8 has a guide rail 10 and a driver element or rail sliding element 12 coupled to the windowpane 4.

[0065] In the exemplary embodiment shown, the window regulator 2 is constructed as a simply guided cable window regulator. The actuating mechanism 8 in this case has a cable pull 14 in addition to the guide rail 10.

[0066] The actuating motor 6 of the window regulator 2 drives a cable drum 18 of the actuating mechanism 8 through a worm gear or spur gear 16. A pull cable of the cable pull 14 is disposed on the cable drum 18, in such a way that when the cable drum 18 is rotated, brought about by the gear mechanism 16, the pull cable is wound up and unwound.

[0067] An upper cable deflection pulley 20 and a lower cable deflection pulley 22 which are disposed on opposing (rail) front faces are fastened to the guide rail 10. The pull cable of the cable pull 14 is guided around the cable deflection pulleys 20, 22.

[0068] When the actuating motor 6 is actuated, the windowpane 4 is moved into the (pane) position P thereof. The windowpane 4 in this case 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 positions S and O the windowpane 4 is indicated in each case in dashed lines in FIG. 1. However, in a half-open intermediate position the windowpane 4 is represented by solid lines.

[0069] Hereinafter, information regarding the spatial directions is also specified in a coordinate system of the motor vehicle (vehicle coordinate system) relative to the exemplary installed situation in a side door of the motor vehicle. The abscissa axis (X-axis) in this case is oriented in the vehicle longitudinal direction, the ordinate axis (Y-axis) is oriented in the vehicle transverse direction and the applicate axis (Z-axis) is oriented in the vehicle vertical direction.

[0070] The longitudinal direction of the guide rail 10 (rail longitudinal direction) in this case is oriented approximately parallel to the applicate axis (Z), wherein the transverse direction of the guide rail 10 (rail transverse direction) is oriented substantially parallel to the abscissa axis (X). The vertical direction of the guide rail 10 (rail vertical direction) is oriented perpendicular to the rail transverse direction and the rail longitudinal direction and thus runs approximately parallel to the ordinate axis (Y).

[0071] In FIG. 2 a section of a cable deflection region 24 of the window regulator 2 or the guide rail 10, i.e. the front-side rail end region on which the cable deflection pulley 20 is disposed, is shown in more detail.

[0072] The cable deflection region 24 shown in FIG. 2 has an approximately cylindrical bearing point 26 which is integrally formed, i.e. in one piece or monolithically, the cable deflection pulley 20 being positioned thereon so as to be able to rotate or turn. The bearing point 26 or the cable deflection region 24 in this case are constructed without screws or bolts, and this means that no additional fastening elements are disposed in the bearing point 26.

[0073] In the mounted state, the window regulator 2 is premounted on a carrier plate 28 of a door module 30 shown in FIG. 3. The carrier plate 28 is configured and provided to be fixed to a door structure 32. In this case, the carrier plate 28 is configured as a (door) module carrier or unit carrier on which further functional components of a vehicle door, not shown in more detail, may be mounted in addition to the window regulator 2. In the exemplary embodiment shown in the figures, the door structure 32 is configured as a window frame structure and in this case may also be constructed as part of a door inner panel.

[0074] When the door module 30 is installed as intended in a side door of a motor vehicle, this door module—and also the carrier plate 28 and the door structure 32—has an inner face 34 and an outer face 36. In this case in the installed or mounted state, the inner face 34 faces an interior (passenger compartment) of the motor vehicle and the outer face 36 faces a region outside the motor vehicle. FIG. 3 shows a view of the inner face 34 of the door module 30.

[0075] A plurality of interfaces may be seen on the inner face 34 of the door module 30 or the carrier plate 28 for connecting to a door frame, not shown in more detail, of the door structure 32 or of the door inner panel, in the form of fastening openings 38. In this case the fastening openings 38 are disposed on an edge 40 of the carrier plate 28. The fastening openings 38 are provided in the figures with reference numerals merely by way of example.

[0076] As is visible for example in FIG. 2, the guide rail 10 extends with the cable deflection region 24 beyond the outer edge 40 of the carrier plate 28. In particular, the cable deflection region 24 in this case protrudes approximately perpendicularly above the upper edge of the carrier plate 28.

[0077] In this case the cable deflection region 24 is configured as a (joining) interface of the carrier plate 28 with the door structure or the window frame structure 32 of the door inner panel.

[0078] As is shown for example in FIG. 4, the door structure 32 has a receiving contour 42 in the form of a lead-through opening penetrating the door structure 32. The receiving contour 42 is incorporated in an operating region 44 of the door structure 32, the operating region being integrally formed on a lower edge of the door structure 32 facing the carrier plate 28. The receiving contour 42 in this case has a relatively narrow slot region or guide slot 42a and a relatively wide insertion region 42b leading therein.

[0079] FIG. 5 shows the cable deflection region 24 in a perspective plan view. As is relatively clearly visible in FIG. 5, the cable deflection region 24 is provided with a protruding joining contour 46 which is form-lockingly inserted in the receiving contour 42 of the door structure 32 in the joined or mounted state shown in FIG. 3.

[0080] The joining contour 46 and the function thereof is described in more detail hereinafter with reference to FIGS. 6 to 9.

[0081] The guide rail 10 or at least the cable deflection region 24 is produced as an injection-molded part in which the joining contour 46 is integrally formed, i.e. in one piece or monolithically. The joining contour 46 in this case is disposed on a side of the cable deflection region 24 opposing the bearing point 26. In the exemplary embodiment shown, the joining contour 46 is disposed on the inner face 34 of the cable deflection region 24.

[0082] As is visible in particular in FIG. 6, the joining contour 46 in this case has in the XY-plane a substantially T-shaped cross-sectional shape with a vertical T-shaped limb 48 oriented approximately along the Y-axis, and with a horizontal T-shaped limb 50 oriented approximately in the X-direction. The T-shape is shown in dashed lines in FIG. 6. A reinforcing rib 52 is integrally formed on the T-shaped limb 50 as an extension of the T-shaped limb 48. The joining contour 46 and the reinforcing rib 52 extend in this case along the Z-axis.

[0083] Due to the T-shaped geometry, the joining contour 46 may be produced without a slide during the injection-molding process of the cable deflection region 24.

[0084] The joining contour 46 is constructed and embodied in such a way that when the joining contour is inserted in the receiving contour 42, the joining contour 46 at least partially form-lockingly engages behind the receiving contour 42 in such a way that the cable deflection region 24 is stabilizingly held along the Y-axis. This means that loads, stresses and forces which occur between the cable deflection region 24 and the door structure 32 by using the joint connection, and which act on the cable deflection region 24 or the bearing point 26, are at least partially transferred to the door structure 32.

[0085] As is shown in FIG. 7, the joining contour 46 is inserted into the receiving contour 42 in a mounting direction M which is oriented substantially in the rail longitudinal direction or Z-direction. In this case, the joining contour 46 is guided in the insertion region 42b and the guide slot 42a.

[0086] As is relatively clearly visible in FIGS. 8 and 9, the vertical T-shaped limb 48 of the joining contour 46 in the inserted state or joined state (mounted state) engages form-lockingly in the guide slot 42a of the receiving contour 42. The guide slot 42a is oriented at least partially along the Z-axis. The guide slot 42a thus acts, in particular, as a positioning or mounting aid or insertion aid when joining the door structure 32 and the carrier plate 28. Moreover, a form-locking of the vertical T-shaped limb 48 and thus of the cable deflection region 24 is produced by the guide slot 42a along the X-axis.

[0087] As is relatively clearly visible in FIGS. 8 and 9, the T-shaped limb 48 of the joining contour 46 is disposed substantially between the inner face 34 of the cable deflection region 24 and the outer face 36 of the operating region 44. The T-shaped limb 50 is disposed on the inner face 34 of the operating region 44 or of the door structure 32, so that the horizontal T-shaped limb 50 engages at least in some sections behind the guide slot 42a of the receiving contour 42. As a result, a more reliable and operationally safe form-locking is produced between the cable deflection region 24 and the door structure 32 along the Y-axis.

[0088] A second exemplary embodiment of the receiving contour 42′ and the joining contour 46′ is described in more detail hereinafter with reference to FIGS. 10 to 12.

[0089] The joining contour 46′ shown in FIG. 10 has in this embodiment two bearing surfaces 54 and 56 which face one another and which are integrally formed, i.e. in one piece or monolithically, on the inner face 34 of the cable deflection region 24. The bearing surfaces 54 and 56 are disposed substantially parallel in the XZ-plane and spaced apart from one another in the Y-direction.

[0090] The bearing surface 54 has two lateral reinforcing or holding ribs 58, which are spaced apart from one another in the X-direction and between which a transverse surface 60 is provided. The bearing surface 56 is configured as a counter rib which is disposed opposing one of the holding ribs 58. For example, in this case a second counter rib of the bearing surface 56, which is disposed opposing the other holding rib 58, is provided.

[0091] The receiving contour 42′ is shown in FIG. 11. The receiving contour 42′ is not closed over the periphery, in contrast to the receiving contour 42, but is configured to be open in the direction of the joining contour 46′ or in the direction of the carrier plate 28. The receiving contour 42′ in this case has a mating surface 62 which—as visible in FIG. 12—is form-lockingly gripped or grippable between the bearing surfaces 54 and 56 of the joining contour 46′.

[0092] The mating surface 62 has two surfaces 64, 66 which transition into one another through a stepped contour 68. The surfaces 64 and 66 are oriented substantially in the XZ-plane and thus parallel to the bearing surfaces 54, 56, whereby a stepped or shoulder-shaped surface offset is produced in the Y-direction by the stepped contour 68. The stepped contour 68 thus produces a tolerance compensation in the Y-direction during the mounting procedure.

[0093] In order to mount or join the door structure 32 to the cable deflection region 24, the receiving contour 42′ is inserted in the Z-direction into the receiver formed between the bearing surfaces 54, 56, so that the surfaces 64, 66 of the mating surface 62 are encompassed at least in some sections by the bearing surfaces 54, 56.

[0094] For a simplified insertion of the mating surface 62 between the bearing surfaces 54, 56, the free ends of the holding ribs 58, i.e. the regions of the holding ribs 58 protruding over the transverse surface 60 in the Z-direction, are provided with a lead-in portion or bevel 70 as a guide contour. The lead-in portion 70 in this case has a path tapering toward the tip. In other words, an inclined slope which acts as an insertion or positioning aid when joining the door structure 32 to the cable deflection region 24 is formed in the Z-direction.

[0095] Preferably, the holding ribs 58 of the joining contour 46′ are configured flexibly or resiliently, wherein in the mounted or joined state a spring force or restoring force which is oriented in the Y-direction is generated, the force producing a clamped force-locking of the mating surface 62 between the bearing surfaces 54, 56 as a mechanical pretensioning.

[0096] A third exemplary embodiment of the receiving contour 42″ and the joining contour 46″ is described in more detail hereinafter with reference to FIGS. 13 to 16.

[0097] In this embodiment, the joining contour 46″ shown in FIG. 13 and in FIG. 14 has two bearing surfaces 54′ and 56′ which face one another and which are integrally formed, i.e. in one piece or monolithically, on the inner face 34 of the cable deflection region 24. In this exemplary embodiment, the bearing surface 56′ is configured as two holding ribs which are disposed in the X-direction offset on both sides relative to the bearing surface 54.

[0098] FIGS. 15 and 16 show the receiving contour 42″. The receiving contour 42″ in this case has a mating surface 62′. In this embodiment, the mating surface 62′ has two surfaces 64′ and one surface 66′ which are disposed alternating or alternately in the X-direction. In this case, the centrally disposed surface 66′ is disposed in each case through a stepped contour 68′ so as to be offset relative to the surfaces 64′. The surface 66′ protrudes over or above the surfaces 64′ thus at least in some sections in the Y-direction.

[0099] As is visible, in particular, in FIG. 16, the mating surface 62′ or the surfaces 64′, 66′ are provided with a lead-in portion or bevel 72 at the free end side.

[0100] The invention is not limited to the exemplary embodiments described above. Rather, other variants of the invention may be derived therefrom by the person skilled in the art without departing from the subject of the invention. In particular, all of the individual features described in connection with the exemplary embodiments may also be combined together in a different manner without departing from the subject of the invention.

[0101] In particular, other cross-sectional shapes of the joining contour 46, 46′, 46″ and/or the receiving contour 42, 42′, 42″ are also conceivable. The conjunction “and/or” is to be understood here and hereinafter in such a way that the features linked together by using this conjunction may be configured both together and as alternatives to one another.

[0102] It is also conceivable, for example, that the joining contour 46′, 46″ or the bearing surfaces 54, 54′, 56, 56′ are formed by using different components. It is also conceivable that the mating surface 62, 62′ is configured in multiple pieces, in particular it is possible that the surfaces 64, 64′, 66, 66′ are formed from two different components.

[0103] It is also conceivable, for example, that the joining contour 46′, 46′ is provided with a damping element.
