    DETAILED DESCRIPTION OF THE INVENTION

    [0043] Parts and sizes which correspond to one another are always provided with the same designations in all the figures.

    [0044] Referring now to the figures of the drawings in detail and first, particularly to FIG. 1 thereof, there is shown a window lifter as adjusting device of a motor vehicle, with a rail slider assembly 1 and with a carrier plate (carrier) 2, for example of a door module, on which a guide rail 3 is mounted, on which the rail slider assembly 1 is guided.

    [0045] In the following text, specifications with regard to the spatial directions are also indicated, in particular, in a coordinate system of the motor vehicle (vehicle coordinate system) with regard to an exemplary installed position of a window lifter in a side door of the motor vehicle. Here, the abscissa axis (X-axis, X-direction) is oriented along the vehicle longitudinal direction (driving direction), and the ordinate axis (Y-axis, Y-direction) is oriented along the vehicle transverse direction, and the applicate axis (Z-axis, Z-direction) is oriented along the vehicle height.

    [0046] The rail slider assembly 1 has a rail slider 4 which is guided such that it can be moved slidingly on the guide rail 3 in the rail longitudinal direction L, or a driver with a rail slider function, or a rail slider with a driver function as a movable component, and an interface adapter 5. The (mounted) guide rail 3 which is arranged on the carrier plate 2 is oriented in the Z-direction. The carrier plate 2 lies or extends in the XZ-plane.

    [0047] An electric motor drive (cable drive) 12 is coupled in a way which is not shown in greater detail to a cable drum, on which a pull cable 25 (FIG. 3) which is connected to the rail slider 4 as movable component and is guided over rail-side or carrier-side deflection elements 6 is wound as a loop, with the result that, during operation of the window lifter, one cable end is wound onto the cable drum and the other cable end is unwound from the latter. As a result, an adjustment of a window pane 8 which is connected to the rail slider 4 via a pane adapter 7 takes place, in order to move the window pane 8 in the mounted state along the adjustment path between a closed position (first end position) which is shown in FIG. 1 and an open position (second end position).

    [0048] Here, the window pane 8 is a functionalized, in particular electrically switchable or controllable, window pane. This or the pane adapter 7 expediently has an electric contact point for an electrical cable 9 for energizing or controlling the window pane 8 or its actuable layer or coating.

    [0049] A lever arrangement 10 with a first lever 10a and with a second lever 10b is held rotatably on the carrier plate 2. To this end, the first lever 10a is fastened to the carrier plate 2 as a stationary component such that it can be moved rotationally. The second lever 10b is held by a second rotary joint (joint pin 31, FIG. 6) on the rail slider 4 as a movable component such that it can be moved rotationally. The opposite or free lever ends of the two levers 10a, 10b are coupled in a rotary connection (rotary joint) 11 and are held such that they can be rotated or moved pivotably therein with respect to one another about a rotational axis which is oriented in the Y-direction.

    [0050] The window lifter, in particular its lever arrangement 10 and the electrical cable 9 held on it or guided with it, and the guide rail 3, the rail slider assembly 1, 4, 5 which is guided thereon, the window pane 8 which is coupled to the rail slider 4, and possibly components or parts of the electric motor drive 12 are arranged in what is known as the wet space of the vehicle door. The carrier plate 2 as door module or module carrier separates the wet space from the dry space, facing the vehicle interior compartment, within the vehicle door.

    [0051] The interface adapter 5 which is called adapter for short in the following text is held, preferably releasably, on the rail slider 4. A portion 29 (FIG. 6) of the electrical cable 9 with a connector plug 13 mounted thereon for plug-in contacting with the pane-side or pane adapter-side electric contact point, for example with a mating plug or a plug socket, is held in turn on this interface adapter 5.

    [0052] FIG. 2 shows the rail slider 4 with a guide or sliding limb 4a which faces the guide rail 3 or is guided on the latter, and with a clamping limb 4b. In the mounted state, the window pane 8 or the pane adapter 7 is received by way of a corresponding portion between these two limbs 4a, 4b which form a driver interface 14 for the window pane 8. Here, one of the limbs 4a, 4b can have a latching lug which, during mounting, latches into a corresponding pane or adapter opening of the pane adapter 7. A screw connection can also be provided via a corresponding fixing structure 15 in the form of a screw hole, a threaded hole or the like for a clamping screw.

    [0053] The rail slider 4 has (here, on the guide or sliding limb 4a) a holding structure with the formation of a fastening interface 16 in the form of two tubular, cylindrical or sleeve-shaped receiving chambers 17 which are spaced apart from one another. In addition, the rail slider 4 has (here, on the clamping limb 4b) a grid-like, strut-like or web-like joining contour 19 as further fastening interface 20 on the flat side 18 which faces away from the guide rail 3. The fastening interfaces 16, 20 serve for (mechanical) fastening of the interface adapter 5. This suitably has a number of joining elements which correspond with the slider-side holding structure 17 or with the joining contour 19 in order to produce a latching, plug or clip connection.

    [0054] FIG. 3 shows a side view of the rail slider 4 with an L-shaped rail wraparound means as slider interface 21 on a profile portion or an erected guide contour 22 of the guide rail 3, of which details are shown. A low-friction sliding insert 23, in particular made from thermoplastic, preferably from POM (polyoxymethylene), is arranged in the rail wraparound means of the slider interface 21. Cable end bottoms 24, fixed on the cable end side, of corresponding pull cables 25 of the window lever cable pull are seated, in particular in a positively locking manner, in the sleeve-shaped receiving chambers 17 which serve as a holding structure with formation of the fastening interface 16.

    [0055] FIG. 4 shows a side view, turned by 90° in comparison with FIG. 3, of the rail slider 4 with the rail wraparound means as slider interface 21 to the guide rail 3, and with the driver interface 14 in the form of the sliding and clamping limb 4a, 4b.

The interface adapter 5 has joining elements 26, 27 which are adapted to the preferably already existing joining contour 19 of the rail slider 4 in the region of its fastening interface 20, and correspond with it in order to produce or with production of a latching or clip connection as a preferred positively locking connection.

    [0057] As can be seen from FIG. 6, the adapter-side joining elements 27 engage over or behind the joining contours 19 of the rail slider 4 at its fastening interface 20. Here, the interface adapter 5 spans the rail slider 4 completely transversely with respect to the rail longitudinal direction L. In the exemplary embodiment, the interface adapter 5 has two hook-like holding elements 28 for a line or cable portion 29 (FIG. 6) which leads to the connector plug 13, and likewise has hook-like clamping or holding elements 30 for the connector plug 13. A joint pin 31 which is molded onto the interface adapter 26 serves for rotationally movable securing of the second lever 10b of the lever arrangement 10, on which the electrical cable 9 is held and guided.

    [0058] FIGS. 7 to 9 show a second variant of an interface adapter 5 for use as a cable guide for the electrical cable 9. The interface adapter 5 of this variant once again has joining elements 26, 27 which are adapted to the joining contour 19 of the rail slider 4 in the region of its fastening interface 20, and engage over or behind (FIG. 8) this joining contour 19, preferably with the production of a latching or clip connection as a preferred positively locking connection.

    [0059] The interface adapter 5 of this variant has a holding structure 32 which extends in the Y-direction. As can be seen in FIG. 9, this holding structure 32 serves to secure a clamp element 33 for a guide tube 34 as cable guide. In addition, the interface adapter 5 of this variant has a holding contour 35, extending in the X-direction, for the connector plug 13.
