Description

TECHNICAL FIELD

[0001] The invention relates to a window lifter assembly for an adjustable window pane of a motor vehicle, the window lifter assembly having a follower which is guided along an adjustment travel, the follower having two follower legs which are connected via a connecting leg and between which a receiving gap for the window pane is formed. The invention also relates to a follower for such a window lifter of a motor vehicle. BACKGROUND

[0002] Movable window panes are typically moved between a closed position and an open position by means of an electric or electrically operated adjustment device as a window lifter. Such a window lifter usually comprises an electric adjustment drive and an adjustment mechanism of the window lifter assembly which connects, i.e. couples in terms of force transmission technology, the adjustment drive with the window pane, the window lifter assembly being assigned to a motor vehicle door or motor vehicle body.

[0003] In order to guide the window pane, in the case of a vehicle door, the window pane is provided, for example at the lower window edge, with at least one (glass) follower as a glass guide element. Here, the follower can be guided in at least one guide rail which functions as an adjustment rail or guide rail, on a traction cable or at or on a, in particular rail-like, abutment or guide contour of the window lifter assembly, for example of a carrier plate of the vehicle door module, in a manner movable along an adjustment travel oriented in the direction of the vehicle height (Z direction). The statements below in connection with the term "guide rail" should also apply to a traction cable guide or to an abutment or guide contour, wherein it is important that the follower is guided along a predetermined adjustment travel, for example a rail-like guide, a carrier contour guide or a cable guide.

[0004] The followers of the type described above usually have a rail slider made of plastic. The rail slider typically has a base body with a guide region which, in the assembled state, for example surrounds a possibly provided guide rail as a rail surround. In this case, the guide rail is seated in the guide region, wherein the rail slider or the base body and the guide rail are in a mutual fit. The rail slider is supported in the fit in a manner movable along the guide rail, so that the window pane is linearly guided between the closed position and the open position. For example, the base body of the rail slider is coupled with a window pane support as a (glass) follower for mechanical interfacing with the window pane.

[0005] To connect the runner to the window pane, the runner has, for example, two runner legs or clamping legs which are arranged and designed to receive the window pane to be adjusted therebetween, for example in a clamping manner. For this purpose, the runner legs are movable relative to one another. The window pane is received with its lower edge between the runner legs of the runner and is then clamped or clipped between the two runner legs by the two runner legs being brought together. To press the two runner legs together, a screw or bolt as a pressing element can be used, via which one of the two runner legs is brought together with the other runner leg via pressing.

[0006] The runner can also be designed for a screwless, clamping (clipping) of the window pane. For this purpose, it is known, for example from DE 10 2012 223 825 A1, that the connection of the runner to the window pane is achieved without tools via an elastically displaceable latching section with a latching nose. Here, the latching section for connecting the window pane to the runner is elastically displaceable against a resetting force, so that the latching nose of the latching section engages with a recess or a through-opening (window pane-side latching opening) of the window pane under the action of the resetting force and thus establishes the connection of the window pane to the runner.

[0007] For example when the window pane is removed for maintenance, a tool is usually guided, for example via an opening in the door interior of the vehicle door, to the latching nose. As the removal tool hits against the latching nose, the elastically displaceable runner leg is pivoted, wherein the tool can be passed through the glass-side latching opening. Subsequently, the window pane can be pulled out of the runner, wherein, as soon as the glass-side latching opening passes the runner-side latching nose, the latching nose rests against the window pane, in particular in the region of the opening edge of the glass-side latching opening. In this state, the removal tool can first be pulled out of the latching opening and the window pane can subsequently be detached from the runner.

[0008] A problem of this removal process is that the elastically displaceable runner leg, which is also referred to below as the curved leg of the runner, in particular is excessively pressed by the tool and can break the curved leg here. This leads to an undesired damage or to a damage of the runner. SUMMARY

[0009] It is the task of the present application to specify a window lifter assembly which has a runner which can be reliably connected to a window pane of a motor vehicle and can also be detached. In particular, damage to the runner when the window pane is detached should be avoided. Furthermore, a suitable runner for such a window lifter assembly (window lifter) should also be specified. The runner should in particular be arranged and designed for a secure latching connection, in particular without tools, to the window pane.

[0010] A window lifter assembly is provided and designed for adjusting a window pane, in particular of a side door of a motor vehicle, along an adjustment travel and moving it between a closed position and an open position. The window lifter assembly has a (glass) carrier which has two carrier legs connected via a connecting leg, between which a receiving gap for the window pane (glass gap) is formed. To this end, the carrier, for example guided on a guide rail, is approximately U-shaped in longitudinal section or in a side view of the receiving gap, wherein the two U legs form the carrier legs and their connection at the gap bottom forms the connecting leg.

[0011] A first carrier leg, also referred to below as a fixed (carrier) leg, is preferably provided for guiding the carrier along the adjustment travel. In particular, the first carrier leg is configured for being held and guided on a guide rail. The first carrier leg, which has a track slider function in this embodiment, preferably has a track surround, in particular of L shape, which surrounds a track profile of the guide rail or of a cap-shaped guide rail.

[0012] A second carrier leg, also referred to below as a movable carrier leg or also as a curved leg, is (flexibly) displaceable or deformable relative to the first carrier leg and has a latching element (latching nose) which projects into the receiving gap. The latching element (latching nose) engages into a latching opening on the glass side, in particular in the form of a hole or recess in the window pane, when the window pane is placed into the receiving gap of the carrier, or is positively locked or snapped into it. The latching element or the second carrier leg can be brought out of the latching opening on the glass side for removing the window pane.

[0013] The carrier has a blocking element for limiting the swing travel of the second carrier leg when it is displaced relative to the first carrier leg. The blocking element is preferably arranged behind the latching element in the gap longitudinal direction pointing towards the gap bottom of the receiving gap. It is particularly preferred that the blocking element is arranged in the region of the connecting leg of the two carrier legs outside the receiving gap in the gap longitudinal direction, in particular in a connecting section of the connecting leg, in particular shaped therein. In a suitable manner, the blocking element is configured as a blocking contour or abutment contour which projects transversely to the gap longitudinal direction. The blocking element is particularly preferably used for removal limitation. However, it is expediently also used as a bending or displacement limitation when placing the window pane into the carrier or latching it with the carrier.

[0014] In a suitable design, the connecting leg between the two follower legs of the follower is embodied at least in the connecting section or functional section, which is coupled (adjoins) to the gap bottom of the receiving gap and has a blocking element for the removal limitation, to be retracted relative to the movable second follower leg or to be constricted transversely to the gap longitudinal direction of the receiving gap, which receives the pane with the latching opening in the region of the lower edge of the glass.

[0015] The blocking element is suitably formed, on the one hand, by a first abutment contour provided on the first follower leg or in the region of the connecting leg of the two follower legs or in the connecting section of the connecting leg. On the other hand, the blocking element comprises or includes a second abutment contour, which is moved relative to the first follower leg upon displacement of the (movable or flexurally elastic) second follower leg. The second abutment contour comes into abutment with the first abutment contour after the swing path has been covered.

[0016] The blocking element is particularly advantageously formed by hooks which are opposite and / or overlap one another and / or are staggered with one another. The hooks advantageously have a retaining leg and a blocking leg which extends at an angle thereto, for example at a right angle thereto. The hooks overlap one another with their blocking legs.

[0017] A particularly suitable design provides a (second) hook which is connected to the second follower leg, in particular is formed thereon, and a (first) hook which is connected to the first follower leg or to the connecting leg or to the connecting section between the follower legs, in particular is formed thereon. In a suitable manner, the second hook is arranged at a distance from the first hook, which distance decreases as the displacement of the second follower leg and the latching element along the swing path increases.

[0018] A suitable refinement provides that the first hook or its blocking leg is directed toward the second follower leg, and the second hook or its blocking leg is directed toward the first follower leg. It can also be provided that the two hooks are arranged at a distance from one another, in particular their blocking legs on the one hand and / or their retaining legs on the other hand, in particular at a distance which corresponds to the thickness of the pane, such that, after the distance has been closed as a result of the displacement of the second follower leg with the latching element relative to the first follower leg, the second hook, in particular its blocking leg, comes to rest against the first hook, in particular its blocking leg. In other words, the hooks are arranged such that the distance between the hooks or between their blocking legs decreases as the displacement of the second follower leg and the latching element along the swing path increases.

[0019] It can also be provided that contours which extend parallel and inclined to one another are arranged at a distance from one another, which distance corresponds approximately to the pane thickness. By means of the blocking element, a reliable flexural limitation of the (movable or flexurally elastic) second follower leg is achieved, preferably to approximately the pane thickness.

[0020] The latching element is configured in a suitable manner, in particular in the type of a triangular (triangular) latching hook. The latching element preferably has an entry ramp which is inclined towards the gap bottom of the receiving gap and / or a blocking edge which is free of inclination relative to the gap opening of the receiving gap and orthogonal (perpendicular) to the plane of the (movable) second follower leg, the latching element, when connected with the window pane, having the blocking edge preferably completely passing through the latching opening of the window pane.

[0021] The follower which is arranged and designed for a window lifter or window lifter assembly of the type mentioned has a receiving gap between a first follower leg and a second follower leg for a window pane having a latching opening, which is (flexibly) resiliently displaceable relative to the first follower leg, a latching element which is arranged on the second follower leg and projects into the receiving gap for insertion into the latching opening on the pane side, and a blocking function which prevents the follower leg with the latching element from being bent outwards or displaced beyond an allowed extent and / or after a predetermined or predeterminable swivel travel has been reached and / or after a predetermined or predeterminable spacing between the profiles on the leg side has been closed.

[0030] Figure 1 A simplified and schematic illustration of an electric or motorized window lifter assembly 2 as an adjusting device for a (vehicle) window pane 4 of a motor vehicle is shown in Fig. 1. The window lifter assembly 2 is assigned a regulating drive 6 which, by means of an adjusting mechanism 8, acts on the window pane 4 with a follower 10 of the window lifter assembly 2. In the embodiment shown, the adjusting mechanism 8 has a pull cable 12 and a guide rail 14 of the window lifter assembly, on which the follower 10 is guided in a way that it can be moved in a sliding motion along an adjusting travel V. It is also possible to provide a plurality, for example two, pull cables 12 and / or for example two guide rails, each with a follower guided thereon.

[0031] The regulating drive 6 of the window lifter assembly 2 drives a cable drum 18 of the adjusting mechanism 8 via a worm gear or spur gear transmission 16. The pull cable 12 of a cable pull, for example embodied as a Bowden cable pull, is arranged on the cable drum 18 in such a way that, when the cable drum 18 is turned as a result of the action of the transmission 16, the pull cable 12 is wound up and unwound. The pull cable 12 of the cable pull is guided via a deflection element or deflection roller 20 and is coupled with the follower 10, which itself is guided along the guide rail 14 and here moves the window pane 4 along with it.

[0032] When the adjusting motor is actuated, the window pane 4 is moved along the adjusting travel V into its adjusted or desired (glass) position. The window pane 4 can here be reversibly moved between a closed position S (indicating the highest possible position) and an open position O (indicating the lowest possible position). In these positions S and O, the window pane 4 is respectively indicated in Fig. 1 by a dashed line. While the window pane 4 is indicated in Fig. 1 by a solid line in a half-open intermediate position. Figure 1

[0033] In the following, the explanations with regard to the spatial directions are also explained in the coordinate system of the motor vehicle (vehicle coordinate system) with regard to an exemplary mounting situation in a side door of the motor vehicle. The transverse axis (X axis) is here oriented in the vehicle longitudinal direction, the longitudinal axis (Y axis) is oriented in the vehicle transverse direction, and the vertical axis (Z axis) is oriented in the vehicle height. The axial direction A is here oriented parallel to the transverse axis (X), while the radial direction R is oriented substantially parallel to the longitudinal axis (Y).​

[0034] Figures 2 to 4 The follower 10 is shown in different views. The orientation of the shown follower 10 corresponds to the directions X, Y, Z of the drawn vehicle coordinate system. The follower 10 is constructed substantially U-shaped or V-shaped and has a first follower leg 10a and a second follower leg 10b. Between the follower legs 10a and 10b a receiving gap or glass gap 21 is formed having a gap opening 22 and a gap bottom 23. The follower legs 10a and 10b are connected to each other via a connecting leg 10c. The connecting leg 10c has a narrowed connecting section or functional section 10d which is retracted in the X direction or gap transverse direction Rx of the receiving gap 21. This connecting section or functional section extends up to the gap bottom 23 of the receiving gap 21.

[0035] The first follower leg 10a has a substantially L-shaped track surround 24 in cross section ( Figure 3 ). The follower 10 is seated with this track surround on the substantially hat-shaped guide rail 14 and there on the correspondingly shaped guide rail section. In the track surround 24 in an embodiment a slide 25 is inserted which is made of a low-friction material, for example polyoxymethylene (POM). In the assembled state of the window lifter assembly 2 the first follower leg 10a is guided along and held on the guide rail 14. Therefore, the first follower leg 10a is also referred to in the following as the fixed follower leg of the follower 10. The fixed first follower leg 10a has an entry ramp 30 ( Figure 4 ) in the region of the gap opening 22 of the receiving gap 21.

[0036] The second follower leg 10b is elastically displaceable or elastically bendable deformable relative to the fixed first follower leg 10a and therefore movable in particular in the Y direction. On the second follower leg 10b which is also referred to in the following as the movable or bending leg a latching element 27 is shaped which projects into the receiving gap 21 (in the Y direction). The latching element 27 is configured as a triangular latching hook and has an entry ramp 28 which is inclined towards the gap bottom 23 of the receiving gap 21 and a non-inclined blocking edge 29 which is orthogonal (perpendicular) to the XZ plane of the (movable) second follower leg 10b relative to the gap opening 22 of the receiving gap 21. The (movable) second follower leg (bending leg) 10b also has an entry ramp 28 in the region of the gap opening 22 of the receiving gap 21.

[0037] The pane 4 can be easily and without error placed into the accommodation gap 21 of the runner via or by means of the entry ramp 26, 30 on the leg side of the runner 10. The pane 4 is placed into the accommodation gap 21 with its lower glass edge in front via the gap opening 22 between the two runner legs 10a and 10b and is latched in the accommodation gap 21. Here, the pane 4 slides with its lower glass edge along the inclined entry ramp 28 of the latching element or latching hook 27. Here, the movable second runner leg 10b of the runner 10 is elastically bent in the Y direction and the latching element 27, in particular, is positively locked, engages or latches into the latching opening 31 of the pane 4 depicted in Figure 6a and Figure 6b . In the latching connection of the pane 4 with the runner 10, the latching element 27 or its blocking edge 29 passes through the latching opening 31 on the pane side as completely as possible.

[0038] The runner 10 has a blocking function, in particular, provided (implemented) by a blocking or abutment contour. This blocking function prevents the runner leg 10b with the latching element 27 from being bent outwards beyond the permissible extent due to a pressure F( Figure 6a , 6b ) acting on the latching element 27 in the Y direction, in particular, in the case of removal of the pane 4. Thereby, the second runner leg 10b is prevented or blocked from being bent outwards beyond the permissible extent and a breakage of the second runner leg 10b is reliably prevented.

[0039] To this end, the runner 10 has blocking elements 32, 33 for limiting the swing travel W of the second runner leg 10b in its displacement relative to the first runner leg 10a, which is shown in Figure 4 . The blocking elements 32, 33 are arranged behind the latching element or latching hook 27 in the gap longitudinal direction Rz pointing to the gap bottom 23 of the accommodation gap 21. In an embodiment, the blocking elements 32, 33 are arranged in the gap longitudinal direction Rz outside the accommodation gap 21 in the region of the connecting leg 10c of the two runner legs 10a, 10b and are preferably arranged in the connecting section 10d of the connecting leg 10c there. The blocking elements 32, 33 are configured as blocking or abutment contours which project transversely to the gap longitudinal direction Rz, i.e. in the gap transverse direction Rx or in the X direction.

[0040] To this end, in Figure 4 and Figure 5In the embodiment shown, two opposing and / or overlapping and / or interleaved hooks 32 and 33 are provided as blocking elements. In other words, the blocking elements are formed by the first hook 32 as abutment contour and the second hook 33 as second abutment contour, which are rigidly connected to the first follower leg 10a in the region of the connecting section 10d, the second hook (second abutment contour) being moved along when the (movable or flexurally elastic) second follower leg 10b is displaced relative to the first follower leg 10a. After the swivel travel W has been covered, the second hook 33 abuts against the first hook 32. The blocking elements serve for removal limitation when the pane 4 is removed from the follower 10, but can also be used as flexural or displacement limitation when the pane 4 is inserted into the follower 10 or latched therewith.

[0041] As shown in the embodiment shown in Figure 5 The hooks 32, 33 have a holding leg 32a, 33a and a blocking leg 32b, 33b extending at an angle thereto, for example at a right angle. The hooks 32, 33 overlap with their blocking legs 32b, 33b the blocking legs of the respective other hook 33b, 32b. The first hook 32 and the second hook 33 are arranged at a hook or contour spacing a, which decreases as the second follower leg 10b and the latching element 27 are displaced along the swivel travel W. Here, as a result of the displacement of the second follower leg 10b with the latching element 27 relative to the first follower leg 10a along the swivel travel W, the hook 33 or its blocking leg 33b, which is assigned to the second follower leg 10b, in particular is formed on the second follower leg, is moved towards the virtually stationary hook 32 or its blocking leg 32b, which is formed on the first follower leg 10a, in particular, and is stopped after the spacing a has been covered.

[0042] Figure 6a and Figure 6b It is explained how the spacing a becomes smaller and smaller as a result of the pressure F acting on the latching element 27 of the movable second follower leg 10b as the latching element 27 is displaced in the Y direction. In this embodiment, inclined and in particular mutually parallel contours 32', 33' are provided as blocking elements, the spacing a of which likewise corresponds approximately to the glass thickness of the pane 4 (as in the embodiment of Figure 4 and Figure 5 the embodiment shown.

[0043] A (removal) tool 34 is shown, which acts with a pressure F on the latching element 27 of the second follower leg 10b, which is guided in a manner not shown via an opening in a body part or a door part to the latching element 27. In the embodiment shown, the tool 34 is designed as a wedge, which is inserted into the opening and is pressed against the latching element 27. Figure 6bIn this position, the tool 34 is passed through the latching opening 31 on the glass side, and the window pane 4 has already been pulled out of the receiving gap 21 of the runner 10 by a small stroke. In this position, the latching element 27 is already resting on the vehicle window 4, so that the tool 34 can be removed.

[0044] It can be seen that the spacing a between the blocking elements 32' and 33' is completely traversed here, and the profiles 32' and 33' rest against one another. In the region of the gap opening 22 of the runner 10, the spacing c between the runner legs 10a and 10b is increased by the glass thickness d of the window pane 4, so that the vehicle window 4 can be completely removed or detached from the runner 10.

[0045] It can be seen from a comparison of Figure 6a and Figure 6b Figure 6b that, after the predetermined spacing a between the leg-side profiles 32, 33 is closed due to the swivel movement of the second runner leg 10b along the swivel path W in the Y direction, further outward bending of the second runner leg 10b with the latching element 27 in the Y direction is blocked.

[0046] In summary, the application relates to a window regulator assembly 2 for an adjustable window pane 4 of a motor vehicle, having a runner 10 with a first runner leg 10a and a second runner leg 10b which is (bend- elastically) displaceable relative to the first runner leg and a latching element 27 which projects into a receiving gap 21 between the runner legs 10a, 10b, which latching element, when the window pane 4 is introduced into the receiving gap 21 of the runner 10, is inserted into a latching opening 31 on the glass side, wherein the runner 10 has a blocking function which blocks or prevents the outward bending or displacement of the second runner leg 10b beyond an allowed extent and / or after a predetermined or predeterminable swivel path W has been reached and / or after a predetermined or predeterminable spacing a between the leg-side profiles 32, 33 or 32b, 33b is closed.

[0047] Preferably, the runner 10 for this purpose has a resting profile 32, against which the second runner leg 10b bears as a result of a pressure force F acting onto the latching element 27 via the window pane 4 in the closed direction or in the closed position S, inter alia for the purpose of detaching a window pane 4 latched in or snapped to the runner 10. Further preferably, for this purpose a blocking profile 33 is provided on the second runner leg 10b, which is spaced apart from the resting profile 32, inter alia in the Y direction. By means of the blocking elements 32, 33 or 32', 33', formed inter alia by profiles, a reliable bending limitation of the (movable or bend- elastically) second runner leg 10b is achieved, preferably to approximately the glass thickness of the window pane 4.

[0048] The application is not limited to the embodiments described above. Rather, further variants of the application can be derived by the person skilled in the art without departing from the subject matter of the application. In particular, all individual features described in connection with the embodiments can also be combined with one another in other ways without departing from the subject matter of the application. Thus, the blocking element can also be embodied as a hinge, an expansion element, a hard stop or a combination of the geometrical shapes mentioned or described.
