Description

The present invention relates to a device for adjusting the position of the window lifter mechanism of a rear window of a motor vehicle. BACKGROUND OF THE INVENTION The invention relates to a device for adjusting the position of the window regulator mechanism of a rear window of a motor vehicle. The invention applies more particularly to vehicles of the two or four-seater cabriolet type comprising a movable rear quarter window fixed to the support of an adjustment device according to the invention as well as to vehicles of the coupé type with four side doors, without a middle foot between the front door and the rear door, these doors being devoid of frame, the movable window of each rear door being fixed to the support of an adjusting device according to the invention. In these vehicles, the front edge of the rear quarter window, in the case of convertibles, or the front edge of the rear door window, in the case of coupes, rejoins the rear edge of the front door window. In these vehicles, the adjustment of the movable window relative to the roof and the joints is to be achieved when the vehicle is assembled and almost completed. In the case of the convertibles and coupés above, the window regulator mechanism of the window is first fixedly mounted on the body and the window is then screwed to the mechanism by means of three bolts. To adjust the position of the window, an operator is placed inside the vehicle and loosens the three bolts above. A second operator is placed outside the vehicle, fixed two suction cups on the glass and by means of shims adjusts the position of the glass so that the games 25 and outcrops meet the quality requirements. At the end of the adjustment, the first operator squeezes the three bolts. To loosen and tighten the three bolts, the operator must be able to access them. For this purpose, one of the following conditions must be fulfilled: either the rear lining is mounted only after the adjustment of the window, which is binding, or the rear lining comprises opposite the three bolts, a detachable element large enough to access the three bolts, which is also binding.

Indeed, this detachable element must, to meet the safety rules, be fixed with the help of fasteners that are robust and therefore expensive. In the case of cabriolets, one can also add the problem of ergonomics for the operator to settle in the back because of the limited space available. The object of the present invention is to overcome these disadvantages. This object is achieved, according to the invention, by means of a device for adjusting the position of the window lifter mechanism of a rear window of a motor vehicle, this mechanism comprising a rigid support intended to be fixed inside. of the rear wing or a rear door of the vehicle, this support comprising means for fixing the window to this support and to guide the movement of this window between a closed position and an open position, characterized in that that: the window is fixed to said support in a definitive manner, the support comprises means making it possible to adjust the position of the support and window assembly with respect to said wing or rear door along the three longitudinal axes X, transverse Y and vertical Z of the vehicle. Thus, the support of the mechanism instead of being fixedly mounted relative to the vehicle is adjustably fixed along the three axes X, Y and Z of the vehicle. In addition, this support is fixed relative to the window and therefore the adjustment of the position of the support allows at the same time to adjust the window. Preferably, said adjustment means are grouped in a reduced area of the support and are accessible through a closable opening located opposite said means on an inner or outer wall of said wing or rear door. Also preferably, the reduced area of the support in which the adjustment means are grouped is located on the lower part of the support, when the support is mounted on the vehicle.

Also preferably, said opening is closable by an outer hubcap or a portion of the vehicle interior trim. The outer hubcap may be an easy rod to mount or disassemble on the outer panel of the rear fender or rear door.

In a preferred embodiment of the invention, said adjusting means comprise three adjustment screws arranged one beside the other and making it possible to adjust the position of the support assembly independently of each other and respectively, along the X, Y and Z axes.

In other words, the adjustment along one of the three axes does not change the setting following the other two axes. In a particularly advantageous embodiment of the invention, the support comprises a metal plate on which are slidably mounted three nuts, a screw being screwed into each of the nuts, this screw being fixed to said wing or rear door and extending into the direction of the Y axis. By screwing or unscrewing the screw, the nut and the plate constituting the support of the device according to the invention are moved, which makes it possible to adjust the position of this support and therefore of the pane according to the invention. Preferably, the three nuts are slidably mounted in a plane perpendicular to the axis of each screw and in a direction inclined with respect to each of the axes X and Z. Preferably also, each of the three screws can be locked. or unlocked with respect to the sliding nut by means of a lock nut, the release of this counter nut releasing the support along the X and Z axes.

According to an advantageous feature of the invention, the adjustment means along the X and Z axes each comprise a finger integral with the wing or the rear door engaged in an elongate opening made in the support, this finger being connected to a nut. in which is screwed a screw fixed to the wing or the rear door, the displacement of the nut being guided by surfaces oriented so that the screwing or unscrewing of the screw makes up or down the finger along the Z axis , or move the finger forward or back along the X axis, a lock nut to lock the screw relative to the nut. Each of these settings can be done without affecting the settings made along the other axes.

Also preferably, the three sliding nuts are each slidably mounted between the two opposite edges of a notch of the support, these two edges being parallel to the front edge of the window.

Thus, when the lock nuts are loosened, the support and the window can be moved parallel to the front edge of the window, that is to say, also parallel to the rear edge of the front window of the vehicle. According to another aspect, the invention relates to a two or four-seater convertible comprising a movable rear quarter glass fixed to the support of a control device or a four-door coupe with no center stand between the front door and the door. rear, these doors being devoid of frame, the movable window of each rear door being fixed to the support of an adjusting device according to the invention.

Figure 1 shows a convertible roof 1 is closed and which comprises on each side two movable side windows 2, 3. The front window 2 is part of a frameless door and the rear window 3 also called rear quarter window is movably mounted in the rear wing 4.

The windscreen mechanism of the rear quarter window comprises a rigid support 5 which is fixed between the outer panel 4a and the inner lining 4b of the rear wing 4, as shown in FIG. 1. This support 5 comprises slides 6 which guide the descent and the rise of the quarter window 3.

The mechanism of the window regulator will not be described here in detail because it is well known to those skilled in the art. The support 5 also comprises means such that three screws 7 make it possible to fix the window 3 to this support 5. In accordance with the invention, the window 3 is fixed to the support 5 in a non-adjustable manner, that is to say say definitive, so that the window 3 and the support 5 form a one-piece assembly. In addition, the support 5 comprises means, which will be described in detail later, for adjusting the position of the support assembly 5 and window 3 relative to the wing 4 along the three longitudinal axes X, transverse Y and vertical Z of the vehicle. These adjustment means are grouped in a reduced area 8 of the support 5 and are accessible to an operator by a closable opening 9, 10 located opposite said means on an inner wall (see Figure 13) or outer wall 4a of the wing 4. The reduced area 8 of the support 5 is located on the lower part of the support 5, when this support is mounted on the vehicle.

The access opening 9, 10 is closable by an outer hubcap 11 such as a rod (see Figure 14) or a portion 12 of the lining 13 of the vehicle. The adjusting means comprise three adjustment screws 15, 23, 24 arranged next to each other at the lower part of the support 5 allowing the position of the support assembly 5 to be adjusted independently of one another. and window 3 respectively along the axes X, Y and Z. In the example shown in Figure 1, the support 5 comprises a metal plate on which are slidably mounted three nuts 14. As shown in Figure 2, a screw 15 is screwed into each of the nuts 14. This screw 15 is fixed to the lining of the wing 4 and extends in the direction of the Y axis. The screwing or unscrewing of the screw 15 has the effect of moving the support 5 in the direction of the Y axis between the two extreme positions 5a, 5b shown in Figure 2. In addition, the three nuts 14 are slidably mounted in a plane perpendicular to the axis of each screw 15 and in a direction inclined by relative to each of the X and Z axes. In addition, each of the three screws 15 is locked relative to the sliding nut 14 by means of a counter nut 16, the release of the counter nut 16 releasing the support 5 along the X and Z axes. FIGS. 1 and 4 to 14 show that the adjustment means along the X and Z axes each comprise a finger 17, 18 integral with the lining 4b of the wing 4 and engaged in an elongated opening 19, 20 made in the supports.

Each of the fingers 17, 18 is connected to a nut 21, 22 in which is screwed a screw 23, 24 fixed to the lining 4b of the wing 4. The displacement of the nut 21, 22 is guided (see FIGS. 5) by surfaces 25, 26 oriented such that the screwing or unscrewing of the screw 23, 24 up or down the finger 17 along the Z axis, as shown in Figures 4 to 9, or advance or move the finger 18 along the X axis, as shown in FIGS. 10 to 12. Moreover, a counter-nut 27, 28 makes it possible to lock the screw 23, 24 with respect to the nut 21, 22. FIG. 1 shows also that the three nuts 14 are each slidably mounted between the two opposite edges of a notch 29 of the support 5. The two edges of the notch 29 are parallel to the front edge 3a of the window 3 which itself must be parallel to the rear edge 2a of the front window 2.

We will now explain the operation of the adjustment device according to the invention. After assembly of the glass assembly 3 and support 5 between the outer skin 4a and the lining 4b of the wing, an operator adjusts the position of this assembly relative to the X, Y and Z axes.

To adjust the position of this assembly relative to the Y axis, it suffices after loosening the locknut 16, to screw or unscrew the screw 15 shown in Figure 2. The rotation of the screw 15 in the nut 14 has the effect of moving the supports in the axis of the screw 15, that is to say along the Y axis between the two extreme positions 5a and 5b. To adjust the position of the glass assembly 3 support 5 relative to the Z axis, it is sufficient after loosening the locknut 27 (see Figure 4) to screw or unscrew the screw 23. The rotation of this screw 23 in the nut 21 has the effect of raising or lowering the nut 21 between the two inclined surfaces 25 shown in FIGS. 5, 7 and 9, which moves the support 5 and the window 3 upwards (see FIG. and 7) or downwards (see FIGS. 8 and 9), that is to say along the axis Z. During the displacement of the nut 21, the finger 17 engages or disengages from the opening elongate, which does not affect the setting of the position of the support 5 relative to the X and Y axes. To adjust the position of the glass assembly 3 and support 5 with respect to the axis X, after unscrewing the lock nut 28 (see figure 3), screw or unscrew the screw 24.

The rotation of this screw 24 in the nut 22 has the effect of moving the nut 22 between the two inclined surfaces 26 shown in Figure 3, which moves the support 5 and the window 3 forwards or backwards of the vehicle, that is to say in the direction of the X axis, as shown in Figures 10 to 12.

To make these adjustments, the operator has access to the screws 15, 23, 24 through the opening 9 located inside the vehicle or through the opening 10 located on the outer skin 4a of the rear wing 4. Furthermore, by rotating the support assembly around the upper front sliding nut 14, taking into account the lateral play of mounting thereof, and acting on the longitudinal adjustment along the X axis, one can optionally adjust the angle of the upper edge of the window 3, the parallelism of the front edge 3a of the window 3 with the rear edge 2a of the front window 2. Given the position of the screws 15, 23, 24 at the bottom of the 5 and the wing 4, the outer opening 10 can be closed by an outer rod 11, as shown in Figure 14. Similarly, the opening 9 located at the bottom of the inner lining 13 can be easily closed by a portion 12 of reduced size of this lining 13, as 13. The vehicle shown in FIGS. 15 and 16 is a coupé which comprises two side doors 30, 31 on each side, each having a window 32, 33 without a frame. In addition, there is no center pillar between the two doors 30, 31. The rear door 31 is equipped with an adjusting device according to the invention which comprises, as in the case of the convertible shown in FIG. a support 5 25 on which the window 33 is fixed permanently by means of three bolts 7. In addition, the support 5 comprises, as in the case of Figure 1, three sliding nuts 14 for adjustment along the Y axis and members allowing adjustment along the X and Z axes. The sectional view shown in FIG. 17 shows the support 5 in position 30 between the outer skin 31a and the lining 31b of the door 31, the screw 15 which is screwed into the lower sliding nut 14 which allows the adjustment along the Y axis.

The access opening to the screw 15 and the screws allowing the adjustment along the X and Z axes can be located on the outer skin 31a or on the inner lining. This opening may be closed by the rod 11 or by a not shown portion of the liner.
