Description

Title of the invention: Door window support for a vehicle for its attachment to a slider of a window regulator device Technical field

[0001] The present invention relates generally to window regulator devices for vehicles, particularly of the automobile type. It relates more particularly to a door window support for its attachment to a slider of such a window regulator device. Prior art

[0002] A vehicle window regulator device conventionally comprises at least one guide rail fixed to the inside of a door of the vehicle and at least one slider carrying the window capable of sliding on the guide rail to ensure the raising or lowering of the window relative to the door.

[0003] It is known to ensure the fixing of the window to the slider by means of at least one pin secured to the slider and designed to pass through a circular orifice of corresponding size provided, either in a lower protrusion of this window projecting below the lower edge of the main part of the latter, or when the window cannot be pierced (case of laminated glass windows) in a lower mounting wall of a window support comprising in its upper part a U-shaped profile stirrup fixedly mounted overlapping on a lower portion of the window. After the pin has been inserted through the orifice, a fork is then snap-fitted therein on the side of the window located opposite the slider so as to prevent the pin from coming out.

[0004] Such a fixing system has the disadvantage of forcing the operator in charge of mounting the window regulator device to install the fork inside the door in an uncomfortable position, especially since the latter must exert relatively significant effort to snap it onto the slider pin.

[0005] Also known, in particular from FR 3 067 054 A1, is a slider for a vehicle window regulator device comprising a jaw comprising two branches facing one another, connected by an elastically deformable hinge zone and defining between them a passage allowing the introduction of a lower protrusion of a window or of the lower mounting wall of a window support.

[0006] A first of these two branches of the jaw further comprises a locking element projecting transversely inside said passage and designed to penetrate into an orifice provided in said lower protrusion of the window or in said lower mounting wall of the window support in order to secure it to said slider.

[0007] This locking element comprises an inclined guide ramp being adapted to cooperate with the lower edge of said protrusion or of said lower mounting wall during its introduction between said branches so as to cause the temporary separation of this first branch.

[0008] This type of assembly with such a slider allows rapid mounting of the window on the slider compared to mounting by fork or screw system. However, it requires perfect alignment of the window hole with the locking element.

[0009] In order to facilitate assembly, document FR 3 113 694 A1 proposes providing at least one centering tab connected to the second branch of the jaw and projecting longitudinally from one side of said jaw, said tab being arranged to cooperate in support with a corresponding edge oriented obliquely of said lower protrusion of the window during its introduction along a substantially vertical insertion axis between said branches and when said orifice is offset longitudinally on the side of this tab with respect to the locking element, so as to cause a longitudinal movement in the direction of the side opposite said tab of this protrusion.

[0010] The presence of this centering tab thus makes it possible, when the orifice provided in the protrusion of the window is offset longitudinally on the side of this tab with respect to the locking element, to ensure the self-centering of this locking element with the orifice during the kinematics of insertion of the window between the two branches of the jaw of the slider.

[0011] This self-centering of the locking element facilitates the blind mounting of the window on the slider by an operator while avoiding the generation of parasitic noise when moving the window up or down via the window lifter device.

[0012] This type of solution cannot, however, be implemented when the orifice is not provided in a protrusion of the window but in the lower mounting wall of a window support. Statement of the invention

[0013] The present invention aims to improve the situation.

[0014] To this end, it proposes a motor vehicle door window support, comprising a bracket designed to be fixedly mounted overlapping on a lower portion of said window as well as a lower mounting wall extending below said bracket and arranged to be introduced along an insertion axis between the two branches of a window regulator device slider, said lower mounting wall having an orifice intended to be crossed by a locking element carried by one of said branches; characterized in that it comprises at least one centering member projecting in relief from one of the faces of said lower mounting wall in front or behind said orifice, each said centering member defining a guide ramp arranged to cooperate in support with one of said branches of said slider, during the introduction of said lower mounting wall between said branches and when said orifice is offset longitudinally on the side of said centering member with respect to said locking element, so as to ensure self-centering of this locking element with said orifice.

[0015] The presence of such a centering member on the support thus makes it possible, when the orifice provided in the lower mounting wall is offset longitudinally on the side of this centering member with respect to the locking element, to ensure its self-centering with this locking element when this support is inserted between said branches of a said slider.

[0016] According to preferred characteristics of said window support according to the invention: - the guide ramp of each said centering member extends along a plane moving away from said orifice in the direction of insertion of this support between the two branches of the jaw of a said window slider; - the guide ramp of each said centering member forms an angle of inclination of at least 5° with said insertion axis; - said angle of inclination is between 5 and 30°; - said angle of inclination is between 10 and 15°; - said support comprises two said centering members arranged longitudinally on either side of said orifice and whose guide ramps are arranged symmetrically with respect to said orifice; - said support is molded in one piece from a thermoplastic polymer, possibly reinforced with natural and / or synthetic fibers; and / or - said stirrup, with a U-shaped profile, comprises two parallel side walls extending opposite each other as well as a base connecting the lower ends of these two side walls and from which said lower mounting wall extends.

[0017] The invention also relates, in a second aspect, to a subassembly comprising a side door window of a motor vehicle and such a support fixedly mounted overlapping on a lower portion of said window.

[0018] Finally, the invention aims, in a third aspect, at a motor vehicle comprising such a subassembly. Brief description of the drawings

[0019] The description of the invention will now be continued by the detailed description of an exemplary embodiment, given below for illustrative but non-limiting purposes, with reference to the appended drawings, in which: - [Fig.l] represents a perspective view of a lower portion of a motor vehicle window on which a motor vehicle door window support according to the invention is fixedly assembled in an overlapping manner; - [Fig.2] is a perspective view of a slider for a motor vehicle window regulator device; and - [Fig.3] and [Fig.4] illustrate respectively an intermediate position and the final position of the assembly kinematics of the glass / glass support subassembly of [Fig.l] on the slider of [Fig.2]. Description of the embodiments

[0020] [Fig. 1] represents a lower portion 2A of a window 2 of a motor vehicle side door on which a window support according to the invention 10 is fixedly assembled in an overlapping manner.

[0021] With reference to this [Fig.l], the window support 10 comprises a U-shaped profile bracket 11 comprising two parallel side walls 13, 14 extending opposite each other and spaced apart by a predetermined spacing slightly greater than the thickness of the window 2 so as to allow the overlapping mounting of this bracket 11 on the lower portion 2A of this window 2.

[0022] The stirrup 11 also comprises a base 15 connecting the lower ends of its two walls 13, 14 and forming a stop for the lower edge of the window 2.

[0023] The final assembly of the window support 10 on the lower portion 2A of this window 2 is conventionally ensured by gluing, advantageously using a single-component elastic adhesive based on polyurethane (PU) such as SikaTack® Ultrafast IL

[0024] Still with reference to [Fig.l], the window support 10 also comprises a flat lower mounting wall 16 extending below the stirrup 11 from its base 15 and extending parallel to its two branches 13, 14.

[0025] This lower mounting wall 16 has a circular orifice 17 passing right through it and advantageously arranged at the level of its central portion.

[0026] The window support 10 is advantageously molded in one piece from a thermoplastic polymer, optionally reinforced with natural and / or synthetic fibers such as glass fibers.

[0027] Preferably, this thermoplastic polymer is chosen from the group comprising acrylonitriles butadiene styrene (ABS), acrylonitriles styrene acrylate (ASA), cellulose acetates (CA), polypropylenes (PP), polyamides (PA), poly(butylene terephthalate) (PBT), polycarbonates (PC), polyethylenes (PE), polyphenylene ether (PPE), polyvinyl chlorides (PVC), or styrene-acrylonitrile (SAN) and their mixtures such as polycarbonate mixtures acrylonitrile butadiene styrene (ABS-PC).

[0028] [Fig. 2] represents a slider 20 for a motor vehicle window regulator device intended to be mounted sliding on a guide rail 30 (visible in figures 3 and 4) and on which the support 10 carrying the window 2 must be secured so as to allow the vertical movement of this window 2 relative to a door of the vehicle.

[0029] With reference to this [Fig.2], the slider 20 conventionally comprises a jaw 21 with a U-shaped profile comprising two branches 22, 23 defining between them a passage allowing the introduction of the lower mounting wall 16 of the support 10 along a substantially vertical insertion axis I.

[0030] The first branch 22 is constituted by a flat wall in the shape of an inverted U, comprising an upper base 22A and two vertical legs 22B.

[0031] The second branch 23 is constituted by a substantially flat wall of greater width than the first branch 22 and having a notch 23A in its upper central part.

[0032] The jaw 21 also comprises two angled tabs 24 connecting the lower ends of its two legs 22B of the first branch 22 to the lower end of the second branch 23.

[0033] This slider 20 also comprises a locking element 25 in the form of a nose, carried by the first branch 22 and projecting transversely inside the window passage in the direction of the second branch 23.

[0034] This nose 25 is designed to pass through the circular orifice 17 formed in the lower mounting wall 16 of the support 10 of the window 2 when the latter is mounted on this slider 20 (its distal end then being housed in the notch 23A formed in the upper central part of the second branch 23, as illustrated in [Fig.2]).

[0035] The two angled tabs 24 form two hinges capable of deforming elastically so as to allow this branch 22 to be able to temporarily move away from the second branch 23 during the introduction of the lower mounting wall 16 of the support 10 into the jaw 21 of the slider 20.

[0036] To do this, this nose 25 comprises a guide ramp 26 inclined downwards between the first branch 22 and its distal end (closest to the second branch 23), this ramp 26 being adapted to cooperate with the lower edge 16A of the lower mounting wall 16 during the introduction of the support 10 with vertical sliding between the two branches 22, 23 of the jaw 21 so as to cause the temporary separation of the first branch 22.

[0037] The slider 20 further comprises two stops made of elastomer material 27 carried by two pilasters 28 extending from the two lateral portions of the second branch 23 projecting laterally on either side of the first branch 22, and provided for cooperate in support, after mounting the window support 10 on this slider 20, with the lower edge of the lower mounting wall 16 of this support 10 in order to prevent any vertical movement of the window 2 with respect to the slider 20 which could cause them to become detached.

[0038] According to the invention and as illustrated in Figures 1, 3 and 4, the window support 10 comprises at least one centering member 18 in the form of a pilaster projecting in relief from one of the faces of its lower mounting wall 16 at the front or at the rear of the circular orifice 17 and defining a guide ramp 18A extending along a plane moving away from this orifice 17 in the direction of insertion of this window support 10 between the two branches 22, 23 of the jaw 21 of the slider 20.

[0039] The guide ramp 18A of each centering member 18 forms an angle of inclination 0 of at least 5° with the insertion axis I of the support 10 and the window 2.

[0040] In this case, the window support 10 comprises two centering members 18 arranged longitudinally on either side of the orifice 17 and whose guide ramps 18A are arranged symmetrically with respect to this orifice 17.

[0041] Such a configuration will for example be preferred in the case of a window regulator device provided with a single slider such as 20 on which a single window support 10 is assembled, in order to ensure automatic centering of the orifice 17 provided in this support 10 relative to a locking element such as 25 and whatever the orientation of the initial longitudinal offset between this orifice 17 and this locking element.

[0042] According to alternative embodiments not shown, the window support 10 may comprise a single centering member 18 arranged at the front or at the rear of this orifice 17.

[0043] Such a configuration will for example be preferred in the case of a window regulator device provided with two sliders mounted to slide on two separate rails and on which are assembled two window supports 10 each provided with a single centering member 18 arranged at the front of its orifice 17 for one and at the rear for the other.

[0044] Generally, the guide ramp 18A of each centering member 18 is arranged to cooperate in support with one of the upper corners of one of the branches 22, 23 (in this case the branch 22) of the slider 20, during the introduction of the lower mounting wall 16 along the insertion axis I between these branches 22, 23 and when the orifice 17 is offset longitudinally on the side of this centering member 18 with respect to the locking element 25, so as to ensure the self-centering of this locking element 25 with the orifice 17.

[0045] More precisely, this guide ramp 18A will thus cause a longitudinal movement in the direction of the side opposite this centering member 18 of this support 10 and of the window 2 fixed thereto as this window 2 descends (see [Fig.3]) and until the lower edge 16A of the lower mounting wall 16 of the support 10 comes into contact with the stops 27 where the orifice 17 is then perfectly aligned with the locking element 25 ([Fig.4]).

[0046] In order to ensure an optimal compromise between the maximum value of the longitudinal offset that can be compensated for and the force that must be exerted by the operator responsible for fitting the window 2, this angle 0 will advantageously be between 5 and 30° and even more preferably between 10 and 15°.
