Description

Window regulator device for a motor vehicle, motor vehicle door and corresponding assembly method 1. Field of the invention

The field of the invention is that of motor vehicles.

More specifically, the invention relates to a window regulator device for a motor vehicle. The invention also relates to a bodywork element with the window lifter device, such as a vehicle door (side door, swinging and / or sliding doors, including the rear doors, tailgates ...), and a method of assembling a motor vehicle door window with the window lifter device. 2. The prior art

Figure 1 illustrates a door 1 to be mounted on a motor vehicle. The door 1 conventionally comprises a box, or frame, door, forming the structure of this door 1. The box comprises an upper frame 101, which defines an opening to be closed by a movable pane 10, and which is connected to a lower part 102.

The door 1 further comprises a window lifter mechanism D which comprises, in a conventional manner, a slider 22 supporting the window 10 and mounted to move in translation on a slideway 21. The slideway 21 is fixed vertically inside the door 1, on the lower part 102 of the latter.

The raising and lowering of the slider 22 on the slide 21 respectively allow the window 10 to be raised and lowered (and thus to close and open the opening formed in the upper frame 101).

The assembly of the window lifter mechanism D first provides for the fixing of the slide 21 and the slider 21 on the inside of the door 1, then the mounting of the pane 10 in the opening of the door 1 and its fastening with the cursor 21 (through, for example, a pin carried by the slider 21 which is engaged in a hole in the window 10.

It is possible that the slider 21 of the slider is not perfectly mounted, which results in an angular offset between the translation axis Ai of the window 10 and the axis A2 of the slider 21 of the slider, as shown schematically in FIG.

This shift is not desirable for the case of Figure 1 where the movable pane 10 is a glass "flush", that is to say, a pane perfectly aligned and flush with the body and guided in guide rails 11 , 12 cooperating with pads 13, 14 integral with the window 10. Unlike the so-called "conventional" windows whose edges move along vertical guides, this particular mounting of the window 10 does not allow movement of the window 10 in guide rails 11, 12.

Therefore, the position of the window 10 can not adapt to the position of the window lifter mechanism D on the door structure 1.

In other words, it is necessary that the window lifter mechanism D is mounted perfectly parallel to the guide rails 11, 12 in the sliding plane of the window 10 and in the plane perpendicular to this sliding plane. If this is not the case, there is a risk of jamming of the window 10 during the raising and lowering maneuvers of the window 10. At the very least, this can cause noise and / or require a significant effort to up or down the window 10 due to a poor sliding of the latter.

In practice, it is difficult to achieve perfect alignment of the translation axis Ai of the window 10 with the axis A2 of the slide 21 of the slider 22, and therefore to a maneuver of the window which is satisfactory and reliable. 3. OBJECTIVES OF THE INVENTION The object of the invention is notably to overcome these disadvantages of the prior art.

More specifically, an object of the invention is, according to at least one embodiment, to provide a window lifter mechanism that is simple to implement and assemble, for example, on an assembly line.

Another object of the invention, according to at least one embodiment, is to provide a window regulator mechanism which allows dispersions on the position of the window regulator on the door structure (i.e. does not require a perfect parallelism between the translation axis of the window and the axis of the cursor rail). 4. Presentation of the invention

These objectives, as well as others that will appear more clearly later, are achieved by means of a window regulator device for a motor vehicle comprising at least one slide along which can slide a slider connected to a mobile window by a device for supporting the window.

According to the invention, the support device of the window comprises at least one deflection means providing the glass three degrees of linear movement of freedom with respect to the cursor.

This or these deflection means arranged between the slider and the window thus make it possible to compensate, according to three axes, the games due to an approximate assembly of the slider of the slider of the movable pane, and provide the pane with three degrees of linear movement of freedom relative to the cursor.

The one or more deflection means of the invention make it possible to eliminate the risks of jamming of the window during raising and lowering maneuvers due to a lack of parallelism between the axis of translation of the window and the axis of the window. the cursor slide. The invention thus provides a reliable window lifter device, ensuring efficient operation of the window, while remaining of a simple construction.

According to a particular aspect of the invention, said at least one means of deflection of the window comprises at least one piece of elastically deformable material.

According to a particular aspect of the invention, the deformable material is an elastomer.

According to a particular aspect of the invention, the support device of the window comprises a support integral with the window and carrying at least one deformable material element on which is mounted a fixing ring of the support device to the slider.

According to a particular aspect of the invention, said support carries at least one stud on which is fitted a deformable material member.

According to a particular aspect of the invention, the ring and the slider carry complementary detent members respectively.

According to a particular aspect of the invention, the slider is fixed to the ring by screwing. The invention also relates to a motor vehicle door equipped with a window lifter device according to the characteristics described above, as well as motor vehicles comprising at least one such window lifter device. The invention relates to a method of assembling a motor vehicle door window with a window lifter device according to the characteristics described above, comprises: a step of mounting the slider guide rail on the door; a step of assembling the window and the support of the window; a step of fixing the support of the window on the slider.

Detailed Description of an Embodiment 6.1 General Principle The invention proposes to provide one or more linear deflection means arranged between the window lifter of a vehicle door and the window which make it possible to compensate, according to three axes, a parallelism defect between the longitudinal axis of the guide rails of the moving window and the longitudinal axis of the slide of the cursor (due to imprecise mounting of the slider of the slider on the door), and a reliable sliding of the window.

This linear movement of the window in three directions is provided by elastic means, such as one or more elastomeric elements disposed between the slider and the window. 6.2 Description of an embodiment

The embodiment described below relates to a front side door of a vehicle. However, of course, the same approach can be implemented on other doors of a vehicle.

In the same way as in FIG. 1, the window regulator device, described below, is fixed inside a door and controls the position of a movable window which is guided in guide rails. last cooperating with skates integral with the window.

The glass is perfectly aligned and flush with the body, this principle being known as the "flush bay".

In the following, the X axis extends in the plane of the window and indicates the direction of travel of a vehicle, the Z axis the direction of translation of the window in the plane of the window, and the Y axis, the direction perpendicular to the X and Z axes.

Figure 4 is a partial view, in perspective, of a window lifter device D according to the invention. This window lifter device D comprises a slider 22 guided in movement along a slideway 21 and connected to a window 10 by means of a support device 3 of the window 10 which is mounted on the lower edge of the window. glass 10.

The slider 22 is movable in the Z direction and integral in motion of the pane 10. The slider 22 can be driven by a cable driven by a geared motor assembly (not shown) or manually by a crank (not shown).

The support device 3 of the pane 10 comprises a support 31, of rectangular shape, interposed between the slider 22 and the pane 10. As can be seen in the sectional view of FIG. 2B along the axis AA of FIG. 2A , the support 31 carries a stud 311 of square section (Figures 3B and 3D) at each of its lateral ends. On the periphery of each of these pads 311 is forcibly mounted a stop 33 of elastomer material, elastically deformable, on which is fitted a ring 32. The ring 32 and the stop 33 are oblong.

The support 31 is glued or screwed on the window 10, the rings 32 being clipped (or snapped) onto the slider 22.

The support device 3 of the pane 10 constitutes connecting means between the slider 22 and the pane 10. Thus, the support 31 is driven by the slider 22 which is itself moved by a drive system (not shown) . The sliding displacement of the slider 22 along the slide 21 allows the displacement of the support 31 and the raising or lowering of the pane 10.

As illustrated in FIG. 4, the slider 22 consists of a central portion 222 coming to face the slide 21, and two lateral wings 223 disposed on either side of the central portion 222. A light 224 of oblong shape is formed on each of the lateral wings 223 and is intended to be placed around the ring 32.

As diagrammatically illustrated by arrows in FIGS. 3B to 3D (FIGS. 3B and 3D being sectional views along the axis BB of FIG. 3A), during the maneuvering of the window 10, the compression of the stop 33 elastomer allows a displacement of the support 31 relative to the ring 32 (and therefore with respect to the slider 22) in the directions X (Figure 3B), Y (Figure 3C) and Z (Figure 3D), the three directions can be cumulated .

In other words, the support 31 of the pane 10 has three degrees of freedom with respect to the slider 22. The abutment 33 of elastomer allows clearance or deflection along the three directions X, Y and Z of the support 31, and therefore of the window 10 when it is slidably driven. Once the pressure on the stop 33 stops, the latter returns to its original shape.

This makes it possible to compensate for a lack of parallelism between the guide rails of the movable pane 10 and the slide of the slider 22 due to an imprecise assembly of the slide 21 of the slider 22 on the door.

The window 10, the support 31, the rings 32 and the stops 33 may be preassembled before mounting on the door. The slider 22 can then be snapped onto the rings 32, as illustrated in FIG. 4 and in FIG. 5 which is a detail view, in section along the C-C axis, of FIG. 2A. To do this, each ring 32 and the slider 22 carry complementary detent members 321, 221 respectively.

In the embodiment of Figure 4, the rim of each slot 224 is snapped into a groove 321 formed on the outer surface of the corresponding ring 32.

In a variant, the slider 22 can be screwed onto the rings 32. 6.3 Other aspects and variants The invention is however not limited to the embodiment described above but is capable of numerous other variations easily accessible to humans of career. For example, it can be applied to other types of opening. The window regulator makes it possible, for example, to operate a rear door window, swing door and / or sliding door (including the rear doors, tailgate, etc.) of a motor vehicle.

It is possible to implement the power window device of the invention in a motor vehicle door having a plurality of guide rails (two for example), a slider being movable in translation on each slide.

Furthermore, the stop may be made of another elastically deformable material that the elastomer.

The window regulator device of the invention can be used, without adaptation, to move a "conventional" window which is not guided in lateral guide rails by means of pads as in the embodiment described above, but whose edges slide inside "U" shaped guides.

Furthermore, the support device 3 of the window 10 may implement only one linear deflection means. Thus, the support 31 may bear only one stud 311 on the periphery of which is mounted a stop 33 of elastomer material, elastically deformable, on which is fitted a ring 32.

The shape of the support 31 is not limited to the examples illustrated in the figures.

Figure 6 is an exploded perspective view of a portion of the support device 3 according to another embodiment. The support 31 carrying a stud 311 is here circular. The abutment 33, of oblong or circular shape, for example, has an interior lumen in which is intended to be housed the stud 311. The ring 32 has an inner lumen in which is intended to be housed the abutment 33.

The method of assembling a motor vehicle door window with a window lift device according to the invention comprises: a step of mounting the slider 21 for guiding the slider 22 on the door; a step of assembling the pane 10 and the support 31 of the pane 10; a step of fixing the support 31 of the pane 10 on the slider 22. The step of assembling the pane 10 and the support device 3 of the pane 10 comprises a step of fixing the ring or rings 32 on the slider 22, and optionally a step of securing the stop or stops 33 to the or rings 32.

In a variant, the stop or stops 33 may be mounted on the support 31.

The support 31 of the pane 10 is then attached to the slider 22.
