Definitions

• the present invention relates to a window regulator for a motor vehicle, of the type comprising:
• Window lifts used in motor vehicle doors usually include a guide rail the length of which a slider carrying the window is movably mounted.
• a metal noise is often heard when closing the door. This noise is due to the beat of the slider against the window of the window regulator. This type of unpleasant noise damages the image of the vehicle.
• FR-A-2 820 451 discloses a sliding window regulator slider on a guide rail.
• the slider has two tabs connecting the latter to the rail in such a way that the rail is gripped by the tongues and without play along the length of the rail, thus avoiding problems of noise and stress caused by defects in the rail. alignment or mounting of the cursor on the rail.
• the object of the invention is therefore to solve this problem.
• the subject of the invention is a window lifter of the above-mentioned type, characterized in that the guide rail comprises at least one projection protruding from the surface of the rail only at a point in the path of displacement, the or each boss being adapted to cooperate with the cursor to reduce the clearance between the cursor and the rail at said point of the travel path.
• each boss is disposed along the length of the rail at the open position of the cursor so that the cursor is supported on said boss when it arrives in the open position;
• the or each boss is a stamped rail
• said slider comprises two guide pads along the length of the rail, the pads being spaced axially along the length of the rail, and the rail comprises two bosses spaced axially along its length, the two bosses being positioned to cooperate simultaneously with each pad;
• said slider comprises two guide pads along the length of the rail, the pads being spaced axially along the length of the rail, and the rail comprises a single boss positioned to cooperate with the pad;
• said slider comprises a single guide pad along the length of the rail, and the rail comprises a single boss positioned to cooperate with the pad;
• said window lifter comprises two rails each having a boss, and at least one slider mounted to move on both rails and adapted to cooperate with each boss;
• the boss is located on the surface of the rail to reduce the play in a direction perpendicular to the shutter plane of the window.
• the invention also relates to a motor vehicle comprising a window lifter as defined above.
• a motor vehicle comprising a window lifter as defined above.
• the invention will be better understood on reading the following description, in which an exemplary embodiment will be described with reference to the appended drawings in which: - Figure 1 is an elevational view of a window lifter according to the invention in the closed position of the window;
• - Figure 2 is a view similar to that of Figure 1 showing the window lifter in the open position of the window; and - Figure 3 shows a cross-sectional view of a window lifter along the axis III of Figure 2.
• FIG 1 and 2 show a window regulator 2 comprising a guide rail 4, a movable slider 6 sliding on the rail 4 and a window 8.
• This window regulator 2 is intended to be implanted in a side door vehicle between the skin of the door and the interior liner, the window 8 out of the door frame by a slot provided for this purpose and flowing in a shutter plane.
• the guide rail 4 is rectilinear and has a length extending in the direction of opening and closing of the pane 8. It has a cross-section I having an end wall 10 having two parallel faces 11 and 12 .
• the window regulator 2 comprises two pulleys 14, 16 located at the ends of the rail 4 and a cable 18 engaged around these pulleys 14, 16.
• the cable 18 has two ends which are fixed to the slider 6.
• the window regulator 2 finally comprises an electric motor or a crank, not shown, driving the cable 18 and moving the slider 6.
• the slider 6 comprises a support plate 20 of the window 8 and two guide pads 22, 24 embedding the rail 4.
• the plate 20 has, for example, the shape of an octagon having two substantially flat surfaces extending in a plane substantially parallel to the plane of the pane 8. It has a thickness smaller than that of the rail 4.
• the outer surface of the pads is attached to one surface of the plate 20 and the two pads 22, 24 are located at two opposite ends thereof.
• the pads 22, 24 are separated axially in the direction of the length of the rail 4.
• the plate 20 is connected to the rail 4 by means of the two pads 22, 24 and the window 8 is mounted on this plate 20.
• Each shoe 22, 24 has a body substantially parallel to the plane of the window.
• the body has a passageway 26 in the form of a channel which passes through it apart. It receives the two faces 11, 12 of the end wall 10 of the rail 4 in this passage 26 allowing the shoe 22 to slide thereon.
• the body has two sides 28, 30 which has in section a U-shape embedding the two faces 11, 12 of the wall 10 of the rail 4, as illustrated in FIG. 3. The same is true for the shoe 24.
• the body has internally a width and a thickness greater than those of the rail 4, so that this difference in width and thickness respectively produces a lateral play in a direction perpendicular to the rail and parallel to the plane of the window and a transverse clearance in a perpendicular direction to the rail and perpendicular to the plane of the window, facilitating the sliding of the pad 22, 24 on the rail 4.
• This clearance is normally between 0.5 mm and 1.5 mm and preferably of the order of 0.9 mm .
• the rail 4 comprises two bosses 32, 34 located on its main surface so as to widen its thickness there. These two bosses 32, 34 are separated axially in the direction of the length of the rail 4 by a distance substantially equal to the distance between the two pads 22, 24.
• the bosses 32, 34 are for example embossed rail.
• the two bosses 32, 34 are located on the main face of the rail 4 at positions substantially corresponding to the two positions of the pads 22, 24 when the window 8 is in the open position.
• the bosses 32, 34 widen the thickness of the rail 4 at this point reducing the transverse play of the rail in a direction perpendicular to the rail and perpendicular to the window.
• the cooperation between the boss 32, 34 and the shoe 22, 24 reduces the transverse clearance so that the transverse clearance that remains is less than 0.1 mm and is especially zero.
• the slider 6 is driven in motion by the cable 18 and slides on the rail 4 along a path of movement between a closed position corresponding to the window 8 in the closed position (FIG. 1) and an open position corresponding to the window 8 in the open position ( Figure 2).
• a closed position corresponding to the window 8 in the closed position (FIG. 1)
• an open position corresponding to the window 8 in the open position ( Figure 2).
• the bosses 32, 34 protruding from the surface of the rail 4 and widening its width at this point each cooperate with a pad 22, 24 ( Figure 3).
• the game between slider 6 and the rail 4 is reduced and the beat of the slider 6 against the rail 4 when closing the door is eliminated.
• the rail 4 comprises a single boss 22, 24.
• the slider 6 also comprises a boss placed opposite the boss belonging to this slider. These two bosses are thus complementary.
• the slider 6 comprises a single pad 22, 24 and the rail 4 comprises a single boss 32, 34.
• the window regulator 2 comprises two rails 4 each having one or two bosses 32, 34 and at least one slider 6 mounted to move on the two rails 4 and adapted to cooperate with each boss 32, 34.
