Ways to carry out the invention

In Fig. 1 is a sectional view of a first embodiment of the device 1 according to the invention is shown, in which the screw 5 in the region of its screw head with the window regulator guide rail 2 by means of an epoxy resin is rotatably and non-displaceably connected. A movement of the screw 5 in the indicated z-direction will thus be carried out completely by the window regulator guide rail 2. The screw 5 extends through the upper locking element 6 and the lower locking element 7 therethrough. An adjustment of the upper locking element 6 in the z-direction is effected by the screw engagement of the screw 5 with a rivet nut 4, the female part 17 has an internal thread. The adjustment of the lower element 7 is again via the screw engagement of the nut 8 with the screw 5, wherein between the lower part 7 of the locking element 6, 7 and the nut 8, a washer 37 is arranged, whose size is a transmission of the displacement of the nut 8 along the screw 5 on the lower part 7 of the locking element 6, 7 allows. The entire latching element 6, 7 rests on a sheet holder 18 and is detachably connected thereto via clip connections, in which locking lugs 23, 24 are introduced into the sheet holder 18 holes are bent during the insertion process and after passing the locking lugs 23, 24 spring back to their original position. The power transmission of the nut 8 on the locking element 6, 7 takes place indirectly via a arranged between the blank holder 18 and the nut 8 washer. The locking lugs 23, 24 provided for the connection of the latching element 6, 7 with the sheet metal holder 18 serve alternatively for connecting the entire device 1 to the inner door panel 13. In the preset version of the device 1 according to the invention shown here, the upper element 6 and the lower element 7 has been set in advance in the y direction. A fixation of the upper element 6 with the lower element 7 in the set relative position takes place not only on the screw 5, but rather on the engagement of the corresponding teeth 35, 36 on the opposite sides of the upper element 6 and the lower element. 7 Slipping out of this locking position is further prevented by means of a plurality of spring elements 16, which form an integral part of the lower element 7 in the illustrated embodiment, completely encompass the upper element 6 and apply a force to the upper element 6 in the direction of the lower element 7. For a readjustment of the relative position of upper element 6 and lower element 7, it is therefore necessary to apply a force against the force applied by the spring elements 16 so far as to apply to the upper element 6, so that this is raised at least by the amount of the toothing height and can then be moved in the y-direction. If at this time the screw 5 is already inserted into the locking element 6, 7, the screw 5 can be moved along the slot 15 in the lower element 7 without further notice. Such readjustment of the locking element 6, 7 in the y-direction can be done as well as an adjustment of the device 1 in the z-direction even after connection of the device 1 with the inner door panel 13, for which purpose the access opening in the inner door panel 13 covering the access door 14 is removed is set and after the adjustment is put back on.

An adjustment of the upper element 7 also takes place in this case via a rotatable threaded nut 4, in which the screw 5 engages. In the case shown, the spring elements 16 are not an integral part of the lower element 7, but are formed as additional components.

FIG. 3 shows a schematic plan view of a device 1 according to the invention, which is arranged between the two ribs 22a, 22b both for insertion aid and for preventing rotation. The ribs 22a, 22b are in the illustrated variant integral components of a function carrier 21, which in turn is connected to the inner door panel 13. Likewise, however, in the case of a door variant without a function carrier 21 as an independent component, such a mounting of the device 1 can take place directly on the inner door panel 13.

4, a third preferred embodiment of the device 1 according to the invention is shown. The locking element 6.7, consisting of upper element 6 and lower element 7 is also connected in the illustrated case with the sheet metal holder 18 via latching elements 23. Also in this embodiment, a bias between the lower element 7 and the upper element 6 by means of a spring element 16 which is an integral part of the lower element 7 and rests on the upper element 6. The screw 5, which passes through the latching element 6, 7 as well as through the sheet holder 8 and is in screw engagement with (not shown) nuts for adjustment in the z-direction, is non-slidably connected to a foot portion of the window regulator guide rail 2. In addition, a cable pull roller 25 for the window regulator mechanism is connected to the window regulator guide rail 2. In order to prevent the window regulator guide rail 2 from rotating during adjustment in the z-direction about the pivot point of the screw 5, an additional screw point is provided in which a screw 20 likewise runs through the foot of the window regulator guide rail 2 and into one Bore on a lateral projection 19 of the upper element 6 engages.

In Fig. 5, the locking element 6, 7 of the third embodiment shown in Fig. 4 is shown in the non-installed state. It can be seen that the lower element 7 is formed substantially symmetrically, with the locking lugs 23 shown on the right side in FIG. 5 also being found on the left side of the figure. The same applies to the spring elements 16. The upper element 6, however, is formed asymmetrically, wherein the bore for the (not shown) screw which is to extend through the projection 19, both laterally and in the longitudinal direction of the locking element 6, 7 offset from the Bore for the (not shown) adjusting screw is arranged.

In this case, the sliding element 26 has two pairs of parallel aligned receptacles into which edge regions of the parapet plate 27 and the window regulator guide rail 2 can engage. Laterally arranged spring elements 28a, 28b thereby cause a tension of sliding element 26 and parapet plate 27th

FIG. 7 shows a perspective view of the sliding element 26 shown in FIG. The sliding element 26 has, in addition to the spring elements 28a, 28b, in addition a Ausrastsicherung 29, the distal end has a projection which protrudes from the plane defined by the receptacles for the (not shown) parapet plate plane.

FIG. 8 shows a schematic perspective view of a part of the parapet plate 27 in the region of the upper attachment point. For this purpose, the parapet plate 27 has a substantially T-shaped opening whose upper, essentially horizontal leg has a width which makes it possible to insert the sliding element (not shown) in the width direction. The distance between the lower leg of the opening 30 delimiting balustrade edges is selected so that it corresponds to the width of the (not shown) sliding member and the receptacles arranged therein for the parapet plate 27 so that a sliding along the sliding member (not shown) along the vertical leg of the opening 30 is made possible. As can also be seen by the person skilled in the art, the length and the arrangement of the safety device 29 shown in FIG. 7 are selected such that it is not possible to pass the sliding element 26 from the vertical part of the opening 30 to its horizontal part without bending the safety device 29 ,

FIG. 9 shows, in a schematic perspective view, the upper part of the window lifter guide rail 2, which is to be attached to the sill plate 27 shown in FIG. 8 by means of the sliding element 26 shown in FIGS. 6 and 7. The window lifter guide rail 2 has for this purpose an opening 31 which is designed so that the slider 26 shown in Figures 6 and 7 can be inserted rotated in the longitudinal direction of the guide rail 2 and is then rotated by 90 ° clockwise that the the opening 31 surrounding edge portions of the guide rail 2 engage in the provided on the slider 26 shots. At the same time, in the illustrated variant, the spring elements 28a, 28b shown in FIG. 7 can engage in the receptacles 32a, 32b arranged adjacent to the opening 31, in order to realize a rotationally fixed arrangement of guide rail 2 and sliding element (not shown). The guide rail 2 also has, in the vicinity of the attachment point, a further deflection roller 33 for the schematically indicated cable pull 34 for the window regulator mechanism (not shown).

FIG. 10 shows an alternative embodiment of the window lifter guide rail 2 (not shown here) with the sill plate 27 shown as an indication. In this case, the sliding element 26 has a substantially cylindrical shape whose diameter is smaller than that of the introduction region 38a of the opening in the parapet plate 27, but greater than the distance of adjacent edge regions of the parapet plate 27 along the displacement path for the sliding element 26 in the parapet plate 27.
