Description

more than they have to exert relatively large effort to ride

  snap the fork onto the pawn of the window support slider. FIGS. 2 to 4 show another known window regulator device according to which each slider 3 is fixed to the pane 4 by means of an interface piece 5 with a tip 6 passing through a hole at the bottom of the pane 4 and a screw 7 passing through a rigid plate 3b of the slider 3, and the end piece 6 of the part 5. More precisely, the end piece 6 of the part 5 is longitudinally split to comprise at least two legs 8 that are elastically separable, one of the other when the screw 7 is inserted through the nozzle 6 and a rigid plate 9 of the part 5 is interposed between the plate 3b of a block 3a of the slider 3 and the window 4. The plate 9 is provided with its upper part of an inverted U shaped profile portion 10 capping the upper edge of the plate 3a of the slider 3 as shown in Figure 3 and can be extended by another plate 11 of the part 5 resting on the face of the plate 3a of the cursor 3 opposite to that comprising the plate 9 as shown in FIG. 4, on which plate 11 bears the head 7a of the screw 7. The assembly is carried out by first introducing the tip 6 of the part 5 through the corresponding hole of the window 4, the latter is then introduced into the door and deposited on the slider 3 by bringing the U-shaped part 10 of the part 5 astride the rigid plate 3a of the slider 3. Then, the operator screws the screw 7 through the piece 5, the plate 3b of the slider 3 and the end piece 6 so as to move the two tabs 8 of the end piece 6 away from each other so as to secure the pane 4 with respect to the slider 3. The inverted U-shaped part 10 prevents a rotation of Coin 5 relative to the cursor.

  This known window lifter device has the major disadvantage that the fixing screws 7 of the glass sliders 3 tend to unscrew in time with the effect of separating the glass slider by ensuring more maneuvering the window. The cause of the unscrewing of these fixing screws is due to the fact that the fixing point of each screw 7 of the slider to the window is offset with respect to the pull point PT of the slider 3 located along the corresponding guide rail as shown. in FIG. 2, which has the effect of tilting around the point PT the cursor at each reversal of direction, up or down, of the window 4, tilting due to the clearance needed to make up for the parallelism defects of the guide rails 1, which has the effect of frictionally driving the head of each fixing screw connecting the slider to the window. The present invention aims to eliminate the above disadvantages of known window lifters. To this end, the invention proposes a vehicle window lifter device, comprising at least one guide rail for moving the window, at least one window support slider slidable on the guide rail, a room interposed between the slider and the pane and having a longitudinally split end-piece passing through a hole in the pane and defining at least two tabs elastically spaced apart from each other on the side of the pane opposite to that in which the slider is located by a fixing screw passing through the slider and the end-piece so as to fix the slider to the window, and which is characterized in that the slider can slide without play on the guide rail and in that at least one slider 30 comprises a buttonhole oriented in a substantially horizontal direction providing for the slider a clearance in the horizontal direction relative to a hollow cylindrical stud through the buttonhole concentrically to the screw and fix transversely to the window 35 opposite the workpiece tip between the latter and the head of the screw, offsetting in this way a parallelism error of the guide rails.

  Preferably, the buttonhole is formed by overmoulding in the slider. The stud is secured to a rigid tongue connected by a hinge hinge to the upper edge of a plate of the part interposed between the slider and the window and from which protrudes the split end, to allow the tongue of be folded over the upper edge of the slider to a position substantially parallel to the window opposite the end piece and to which the end of the stud is held in abutment on the face of the plate of the part opposite to the glass by the bit and screw assembly whose head is supported on the outer face of the folded tongue. The piece has a hook-shaped portion capping the upper edge of the slider to prevent rotation of the workpiece relative to the slider and to ensure premaintenance of the window on the slider. The buttonhole is in sliding contact on the stud by its two horizontal edges.

  The end of the stud is housed concentrically in an annular recess of the plate of the part to prevent the displacement of the stud in the vertical direction. The hinge hinge is located above the upper edge of the slider and comprises a block slidably mounted on the rail and a rigid plate parallel to the window and having the buttonhole. The slider plate is metallic and the overmolding of the buttonhole is made of a plastic material.

  According to an alternative embodiment, the slider and its plate are made in a single block of a plastic material or metal, such as aluminum. In addition, the connecting part of the slider to the pane is made in one block based on a plastic material. The stud of this piece has a dimension in length allowing the horizontal play of the cursor.

  The invention also relates to a part intended for a window lifter device as described above and which is characterized in that it comprises a rectangular plate with a longitudinally split end intended to be inserted into a hole of a window to ensure the assembly from the piece to the window, a rigid tongue connected by a hinge hinge to the rectangular plate and having a stud for traversing in a lateral play a buttonhole of a support slider of the window. Preferably, the piece is integral with a plastic material and the hinge hinge is a film hinge. The invention also relates to a method of mounting a part to a window and a support slider of the window pane of the device as described above, and which is characterized in that it consists in introducing the end piece of the piece in the hole of the glass so that the rectangular plate of the piece is resting on the outer face of the glass, place the glass on the slider, fold the tab of the piece over the slider so as to introduce the stud through the buttonhole of the slider and in the corresponding annular recess of the rectangular plate of the workpiece, fix the window to the slider by the fastening screw introduced through the tab, the stud and the tip so to separate the two tabs of the end-piece from one another and to grip together the rigid tongue, the overmolded buttonhole, the stud, the slider, the plate of the part and the window between the two apart legs and the head of the screw in support on the rigid tongue. The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly in the explanatory description which will follow with reference to the accompanying drawings given solely by way of example illustrating an embodiment. of the invention and in which: Figure 1 is a perspective view of a motor vehicle door comprising a window lifter device of the prior art; Figure 2 shows an enlarged view of the circled portion II of Figure 1; FIG. 3 is an enlarged perspective view showing a known connection between the slider and the window of a window lifter device; - Figure 4 is a perspective view similar to that of Figure 3 and showing an alternative embodiment of this connection; Figure 5 is a perspective view of the window lifter device of the invention; FIG. 6 is an enlarged sectional view in the vertical plane containing the line VI-VI of FIG. 5; Figure 7 is a perspective view of the connecting piece between the slider and the window of the window lift device of Figures 5 and 6; FIG. 8 is a perspective view of the slider of the invention; and FIG. 9 is a perspective view of the slider located opposite the slider of the window lifter device of the invention shown in FIGS. 5 to 8. The window lifter device of a vehicle door shown in FIGS. 5 to 9 comprises two guide rails 1, on which two sliders 3 for supporting the window pane 4 can slide respectively to execute the upward and downward movements of the window pane 4, where appropriate between two slats of the door frame. if the latter is provided. Theoretically, the guide rails 1 are fixed to the inner door panel of the vehicle while being parallel to each other, but in practice there is a lack of parallelism between them.

  Each slider 3 comprises a block 3a slidably mounted on the corresponding guide rail 1 and a generally flat rigid plate 3b integral with the block 3a being offset laterally from the latter.

  The window lifter further comprises a part 5 partially interposed between the rigid plate 3b of each slider 3 and the window 4 and having a longitudinally split end piece 6 passing through a circular hole 4a of the window 4 and defining at least two legs 8 elastically separable from each other on the side of the window 4 opposite that where the plate 3b of the slider 3 is located by a fastening screw 7 passing through the plate 3b of the slider 3 and the end piece 6 so as to fix the slider 3 to the window 1.

  One of the two sliders 3, for example that shown in Figure 9 and slidable along the guide rail 1 fixed in the door 2 to the right of the latter by considering Figure 1, has its offset plate 3b having an orifice 3b1 circular passage of the fixing screw 7 and the part 5 associated with this slider is similar to one or the other of the two parts 5 shown in Figures 3 and 4. The device described until now corresponds to the device Window lift described in Figures 1 to 4.

  According to the invention, the sliders 3 can slide without play respectively on the two guide rails 1 and the other slider 3 comprises a buttonhole 12 instead of a circular hole and which is oriented in a substantially horizontal or longitudinal direction providing for the slider 3 to the buttonhole 12 a clearance in the horizontal direction relative to a hollow cylindrical stud 13 passing through the buttonhole 12 concentrically to the fixing screw 7, the stud 13 being fixed transversely to the window 4 opposite the endpiece 6 between the part 5 and the head 7a of the fixing screw 7. Preferably, the buttonhole 12 is formed by a plastic overmolding in the slider 3 and comprises an oblong portion 12a constituting the buttonhole itself and a collar 12b resting on the face of the plate 3b of the slider 3 opposite to the face of the window on which is supported the part 9 in the form of rectangular plate of the piece 5 interposed between the pane 4 and the plate 3b of the slider 3. The plastic material of the overmolding of the buttonhole may be polyacetal. The oblong hole 12a1 of the portion 12a of the buttonhole 12 has its two parallel horizontal edges in sliding contact on the stud 13 on either side thereof. The stud 13 is secured to a rigid tongue 11 connected by a hinge hinge 14 to the upper edge of the rectangular plate 9 of the part 5 which projects the tip 6 to allow the tongue 11 to be folded by above the upper edge of the plate 3b of the slider 3 to a position substantially parallel to the window 4 opposite the end piece 6 and facing the slider plate 3b 3. In this folded position of the tongue 11, the stud 13, which extends perpendicularly from the corresponding face of the tongue 11, has its end which is held in abutment on the face of the plate 9 of the part 5 opposite the face of the window 4 on which is supported the plate 9 by the nozzle assembly 6, the two lugs 8 are spaced from each other and screw 17 whose head 7a is supported on the outer face of the folded tongue 11. The latter is supported on the outer face of the flange 12b of the buttonhole 12 as This figure also shows that the end of the stud 13 is housed concentrically in an annular recess 15 formed in the plate 9 of the part 5 opposite the end piece 6 so that the end of the stud 13 is supported without radial play on a cylindrical surface 16 of the plate 9 delimited internally by the annular recess 15 and concentric with the fixing screw 7. The plate 9 of the part 5 comprises at its upper edge a tab in hook shape 17 passing over the upper edge of the plate 3b of the slider 3 by capping it to prevent rotation of the part 5 relative to the slider 3. The hinge hinge 14 consists of two parts located above the upper edge of the plate 3b of the slider 3 on either side of the hook tab 17. To ensure the folding of the tongue 11 over the plate 3b of the slider 3 without being hindered by the presence of the tab in crochet 17, the tongue 11 has its end articulated to the inverted U-shaped plate 9 whose lateral branches are connected by the two parts of the hinge hinge 14 to the upper edge of the plate 9. Preferably, the connecting piece 5 is based on a plastic material integrally molded with the tip 6, the pad 13 and the hook tab 17 and the hinge hinge 14 is a hinge of the film type. The slider 3 and its offset plate 3a are advantageously made in one piece of a plastic material or metal, such as aluminum. Of course, in the case where at least the plate 3b of the slider 3 is made of metal, the overmolding of the buttonhole 12 of this slider makes it possible to overcome the burrs due to the cutting of the oblong hole in the plate of the slider and to guarantee smooth slipping or noise of the buttonhole 12 of the slider 3 relative to the stud 13. The mounting of the window lifter device is as follows.

  Firstly, the tip 6 of each connecting piece 5 is inserted into the corresponding circular hole 4a at the bottom of the window 4, the lower edge of which can bear on a right-angled end flange 9a of the plate 9 of the part 5 to prevent rotation of the part 5 relative to the window 4. Then, with regard to the part 5 of the invention, the window 4 is mounted on the slider 3 via the piece 5 whose hook tab 17 bears on top of the upper edge of the plate 3b of the slider 3. The articulated tongue 11 is then folded over the plate 3a of the slider 3 to the position shown in FIG. to introduce the stud 13 through the buttonhole 12 with the end of the stud 13 engaged in the annular recess 15. The fitter can then introduce the screw 7 through the stud 13 and the central bore of the tip 6 so to separate from one another the two legs 8 and fix the piece 5 to the window 4. In this way, the spaced tabs 8 and the screw head 7a resting on the outer face of the folded tongue 11 enclose the assembly formed by the window 4, the plate 9 of the part 5, the plate 3b of the slider 3, the buttonhole 12 and the folded tab 11. The parallelism defect of the guide rails 1 is overtaken by the fact that the slider 3 can slide through its buttonhole 12 on the pad 13 and this sliding is guaranteed by the dimension of the stud 13 in the direction transverse to the window 4, that is to say in the direction Y perpendicular to the longitudinal direction X of the vehicle. In addition, the annular recess 15 and the cylindrical portion 16 of the connecting piece 5 allow the pad not to undergo deflection in the vertical direction, that is to say along the Z axis, during reversals of direction operating the window 4 and this arrangement allows the hinge hinge 14 not to undergo too much force can pass through it because the overmolding 12 forming buttonhole vertically drives the stud 13 of the part 5 with the window 4.

  In addition, the folded tab 11 makes it possible to prevent the screw 7 from being unscrewed. Of course, the other slider 3 is conventionally fixed by a fixing screw 7 entering the circular hole 3b1 of the plate 3b of this slider. to allow the positioning of the window in the door in the longitudinal direction X. The window lifter device of the invention, of the isostatic type, allows a quick and easy assembly of its elements without disturbing the editor and makes up for any lack of parallelism between the two guide rails of the window.
