Description

La présente invention concerne un dispositif de lève-glace notamment de portière de véhicule automobile du type comportant un pignon de commande entraîné par un motoréducteur et engrenant sur une crémaillère solidaire d'au moins une des extrémités de deux bras de manoeuvre à angularité variable en fonction de la position de la glace qui est munie à sa partie inférieure d'une glissière dans laquelle coulissent des rotules disposées à des extrémités des bras qui l'entraînent.The present invention relates to a window regulator device, in particular for the door of a motor vehicle of the type comprising a control pinion driven by a geared motor and meshing on a rack integral with at least one of the ends of two maneuvering arms with variable angularity as a function the position of the glass which is provided at its lower part with a slide in which ball joints are arranged at the ends of the arms which drive it.

Les dispositifs classiques connus de ce type sont constitués par deux bras en tôle découpée, croisés et articulés angulairement en leur centre à la manière d'une paire de ciseaux dont une de leurs extrémités sont aptes à coulisser dans une glissière de la glace pour l'entraîner en montée ou en descente grâce à un motoréducteur d'entraînement dont le pignon de sortie entraîne une crémaillère en forme de secteur disposée à l'autre extrémité d'un des bras, cet ensemble étant monté sur une platine permettant sa fixation dans la portière en plusieurs points.The known conventional devices of this type are constituted by two arms of cut sheet metal, crossed and angularly articulated in their center in the manner of a pair of scissors, one of their ends of which is capable of sliding in a slide of the ice for the drive up or down thanks to a drive geared motor whose output pinion drives a sector-shaped rack disposed at the other end of one of the arms, this assembly being mounted on a plate allowing its fixing in the door at several points.

L'inconvénient majeur de ce dispositif est avant tout l'encombrement important de l'ensemble et le nombre de pièces constitutives d'où un poids relativement important qui va à l'encontre de la tendance actuelle des constructeurs automobiles dont l'objectif principal est l'allégement des véhicules de manière à pouvoir réaliser des économies d'énergie. De plus un tel dispositif, par son encombrement nécessite une ouverture telle, pour son introduction dans la portière qui tend à réduire la rigidité de ladite portière.The major drawback of this device is above all the large size of the assembly and the number of constituent parts, hence a relatively large weight which goes against the current trend of car manufacturers whose main objective is lightening vehicles so that energy savings can be achieved. In addition, such a device, due to its size, requires such an opening, for its introduction into the door which tends to reduce the rigidity of said door.

De plus ce genre de dispositif nécessite une adaptation à chaque véhicule différent et même il nécessite de concevoir deux dispositifs asymétriques par type de véhicule de manière à s'adapter l'un dans la portière de droite, l'autre dans la portière de gauche. Il est évident que la multiplicité de ces créations augmentent les prix de revient et les frais de gestion des stocks.In addition, this kind of device requires adaptation to each different vehicle and even it requires designing two asymmetrical devices per type of vehicle so as to fit one in the right door, the other in the left door. It is obvious that the multiplicity of these creations increases the cost prices and the costs of inventory management.

Afin de remédier à ces inconvénients il a été proposé par la demanderesse dans sa demande de brevet EP-A-0039259, un dispositif ayant l'avantage de ne pas nécessiter de platine support, donc de permettre un allégement du poids, et d'être universel, de manière à limiter les références.In order to remedy these drawbacks, the applicant has proposed in its patent application EP-A-0039259, a device having the advantage of not requiring a support plate, therefore allowing weight reduction, and being universal, so as to limit references.

Ce dispositif comporte un pignon de commande entraînant une courroie de transmission perforée tendue par deux premières poulies dentées de renvoi, et formant un triangle par l'adjonction d'une troisième poulie, courroie rendue partiellement rigide par deux rails articulés à la manière d'un compas autour d'une des poulies de renvoi de manière que, associés au troisième côté souple, ils constituent, un ensemble à la fois homogène et pliable apte à être successivement plié pour son introduction aisée dans la portière et être redéployé pour son positionnement définitif.This device comprises a control pinion driving a perforated transmission belt tensioned by two first toothed return pulleys, and forming a triangle by the addition of a third pulley, belt made partially rigid by two rails articulated in the manner of a compass around one of the deflection pulleys so that, associated with the third flexible side, they constitute an assembly which is both homogeneous and foldable, capable of being successively folded for its easy introduction into the door and to be redeployed for its final positioning.

Ce dispositif remédie à certains inconvénients mais en crée d'autres car si la souplesse d'un des côtés facilite l'introduction dans la portière cela présente l'inconvénient de constituer un ensemble articulé et non compact qui, bien que se passant de platine, nécessite la disposition de plusieurs points de fixation destinés à rigidifier l'ensemble et tendre la courroie après introduction dans la portière.This device overcomes certain disadvantages but creates others because if the flexibility of one of the sides facilitates the introduction into the door, this has the disadvantage of constituting an articulated and non-compact assembly which, although it does not require platinum, requires the provision of several fixing points intended to stiffen the assembly and tighten the belt after introduction into the door.

De plus un tel système limite la course de la glace à l'intérieur de la portière.In addition, such a system limits the travel of the ice inside the door.

Le but de la présente invention est de remédier à tous les inconvénients précités des deux types de lève-glace connus en offrant un ensemble compact et universel, d'une manipulation aisée et d'un poids extrêmement allégé.The object of the present invention is to remedy all the aforementioned drawbacks of the two known types of window lifters by offering a compact and universal assembly, of easy handling and of extremely light weight.

A cet effet elle concerne un dispositif de lève-glace notamment de portière de véhicule automobile du type comportant un pignon de commande entraîné par un motoréducteur et engrenant sur une crémaillère solidaire d'au moins une des extrémités de deux bras de manoeuvre à angularité variable en fonction de la position de la glace qui est munie à sa partie inférieure d'une glissière dans laquelle coulissent des rotules disposées à une des extrémités des bras qui l'entraînent caractérisé en ce que les deux bras de manoeuvre sont disposés de manière radiale par rap- . port au centre d'un boîtier de commande cylindrique, faisant office de platine, sur la périphérie duquel sont guidés, par l'intermédiaire d'un coulisseau, les deux bras radiaux, entraînés dans un débatement angulaire autour du boîtier par au moins une crémaillère souple perforée exerçant sur lesdits bras une poussée ou une traction selon le sens de rotation désirée du pignon de commande sur lequel elle s'engrenne pour être entraînée.To this end, it relates to a window-lifting device, in particular for the door of a motor vehicle of the type comprising a control pinion driven by a geared motor and meshing on a rack integral with at least one of the ends of two maneuvering arms with variable angularity in function of the position of the glass which is provided at its lower part with a slide in which ball joints disposed at one of the ends of the arms which drive it characterized in that the two operating arms are arranged radially in relation -. port in the center of a cylindrical control box, acting as a plate, on the periphery of which are guided, by means of a slide, the two radial arms, driven in an angular movement around the box by at least one rack flexible perforated exerting on said arms a push or a pull according to the desired direction of rotation of the control pinion on which it meshes to be driven.

Selon un mode préférentiel de réalisation le pignon de commande entraîne deux crémaillères souples dont l'une directement et l'autre par l'intermédiaire d'un pignon de renvoi, une des extrémités libres de chaque crémaillère étant formée par une boucle, guidées dans des portions de couloir périphérique du boîtier et entraînant simultanément dans un mouvement convergent ou divergent, les deux bras radiaux solidaires des extrémités desdites crémaillères souples. La description qui va suivre en fonction des dessins annexés fera mieux comprendre comment l'invention peut être réalisée.

Le dispositif de lève-glace représenté sur les figures comprend d'une manière générale un boîtier de commande 1 faisant office de platine, sur la périphérie duquel sont guidés, par l'intermédiaire d'un coulisseau 2, les deux bras radiaux 3 et 4, entraînés dans un débatement angulaire, suivant alternativement les flèches F1-F2, autour du boîtier 1 par au moins une crémaillère souple 5 perforée et solidarisée desdits bras 3 et 4. Pour exercer sur eux une poussée ou une traction selon le sens de rotation désirée d'un pignon de commande 6, entraîné par un motoréducteur 7, et sur lequel elle s'engrenne par l'intermédiaire de ses perforations pour être entraînée et provoquer ainsi le débattement angulaire des bras 3 et 4 aux extrémités libres desquels est disposée une rotule 8 apte à coulisser dans une glissière (non représentée) disposée à la partie inférieure de la glace (non représentée) pour l'entraîner dans un mouvement montant ou descendant dans la portière du véhicule.The window-lifting device shown in the figures generally comprises a control box 1 acting as a plate, on the periphery of which are guided, by means of a slide 2, the two radial arms 3 and 4 , driven in an angular debate, alternately following the arrows F1-F2, around the housing 1 by at least one flexible rack 5 perforated and secured to said arms 3 and 4. To exert on them a push or a pull according to the desired direction of rotation a control pinion 6, driven by a geared motor 7, and on which it meshes through its perforations to be driven and thus cause the angular movement of the arms 3 and 4 at the free ends of which is arranged a ball joint 8 able to slide in a slide (not shown) arranged at the bottom of the glass (not shown) to drive it in an upward or downward movement in the vehicle door.

Egalement d'une manière générale, le motoréducteur 7 est encastré dans un logement 9 correspondant à sa forme extérieure et obtenu au cours d'une même opération de moulage avec le boîtier de commande 1, au verso de ce dernier (fig. 5).Also generally, the gearmotor 7 is embedded in a housing 9 corresponding to its external shape and obtained during the same molding operation with the control unit 1, on the back of the latter (fig. 5).

La disposition des éléments constitutifs du moto-réducteur 7 pourra également s'effectuer tel que décrit dans la demande de brevet FR-A-2 386 924 de la demanderesse à la seule différence que le carter inférieur du moto-réducteur est avantageusement remplacé par le boîtier de commande 1.The arrangement of the constituent elements of the gear motor 7 may also be carried out as described in patent application FR-A-2 386 924 of the applicant with the only difference that the lower casing of the gear motor is advantageously replaced by the control box 1.

Selon un mode particulier de réalisation de l'invention, représenté à la fig. 1, les extrémités libres 5a et 5b de la crémaillère souple 5 sont solidarisées des bras 3 et 4 par l'intermédiaire des coulisseaux 2 qui comportent des moyens de liaison avec ladite crémaillère 5. Les extrémités libres 5a et 5b de la crémaillère 5 forment deux boucles en S, qui sont guidées dans des portions de couloir périphérique 10 obtenues de moulage avec le boîtier 1 et entraînant, simultanément et respectivement par poussée et traction dans un mouvement convergent ou divergent les deux bras radiaux 3 et 4 suivant les flèches F1 ou F2.According to a particular embodiment of the invention, shown in FIG. 1, the free ends 5a and 5b of the flexible rack 5 are joined to the arms 3 and 4 by means of the slides 2 which comprise means of connection with said rack 5. The free ends 5a and 5b of the rack 5 form two S loops, which are guided in peripheral corridor portions 10 obtained by molding with the housing 1 and causing, simultaneously and respectively by pushing and pulling in a converging or diverging movement, the two radial arms 3 and 4 according to the arrows F1 or F2 .

Dans ce mode de réalisation les mouvements opposés des bras 3 et 4 est précisement obtenu grâce à la forme en S donnée à la courroie 5 ce qui a pour effet de transformer un mouvement de traction en mouvement de poussée ou inversement pour l'une des extrémités de la courroie 5.In this embodiment, the opposite movements of the arms 3 and 4 are precisely obtained thanks to the S-shape given to the belt 5 which has the effect of transforming a traction movement into a pushing movement or vice versa for one of the ends belt 5.

Le mode de réalisation représenté aux fig. 2 et 3 montre respectivement en position haute ou basse de la glace un dispositif de lève-glace différent essentiellement du précédent en ce que le pignon de commande 6 entraîne deux crémaillères souples 11 et 12 dont l'une 12 directement et l'autre 11 par l'intermédiaire d'un pignon 13 solidaire d'un pignon de renvoi (non visible ) entraîné par le pignon de commande (6).The embodiment shown in Figs. 2 and 3 respectively show in the upper or lower position of the window a window lifter device essentially different from the previous one in that the control pinion 6 drives two flexible racks 11 and 12, one 12 directly and the other 11 by via a pinion 13 secured to a return pinion (not visible) driven by the control pinion (6).

Les extrémités libres 11a et 12a des crémaillères souples 11 et 12 forment une boucle guidées dans les portions de couloir périphérique 10 du boîtier 1 et entraînent simultanément par poussée ou par traction les bras 3 et 4 dans un mouvement convergent ou divergent.The free ends 11a and 12a of the flexible racks 11 and 12 form a guided loop in the peripheral passage portions 10 of the housing 1 and simultaneously drive the arms 3 and 4 by pushing or pulling in a converging or diverging movement.

La comparaison des fig. 2 et 3 montre bien le déplacement des crémaillères 11 et 12 en fonction de leur entraînement respectif par les pignons 13 et 6 tournant dans des sens opposés et communiquant ainsi aux bras 3 et 4 des mouvements également opposés par l'intermédiaire des crémaillères 11 et 12.The comparison of figs. 2 and 3 clearly shows the movement of the racks 11 and 12 as a function of their respective drive by the pinions 13 and 6 rotating in opposite directions and thus communicating to the arms 3 and 4 also opposite movements via the racks 11 and 12 .

Le mode de réalisation représenté respectivement recto et verso sur les fig. 4a et 4b diffère essentiellement des précédents en ce qu'un pignon de commande double 14, traverse le boîtier de commande 1 et entraîne simultanément et respectivement deux crémaillères souples 15 et 16 disposées de part et d'autre du boîtier 1 et dont une des extrémités libres 15a et 16a de chaque crémaillère 15 et 16 forment une boule guidée dans les portions de couloir périphérique 10 du boîtier 1 et entraîne conséquemment les bras radiaux et4 auxquels elles sont reliées.The embodiment shown respectively front and back in FIGS. 4a and 4b essentially differs from the previous ones in that a double drive pinion 14, passes through the control box 1 and simultaneously drives two flexible racks 15 and 16 respectively arranged on either side of the box 1 and one of the ends of which free 15a and 16a of each rack 15 and 16 form a guided ball in the peripheral corridor portions 10 of the housing 1 and consequently drives the radial arms et4 to which they are connected.

Selon une autre caratéristique de l'invention représentée aux fig. 6 et 7 les bras radiaux 3 et 4, utilisés dans les modes de réalisation précités, sont obtenus par découpe d'un flan en tôle fine dans lequel est conformé par pliage le coulisseau 2 et dont l'extrémité libre 3a comporte une ouverture 17 en forme de boutonnière obtenue par découpage et apte à recevoir la rotule 8 par encliquetage élastique.According to another characteristic of the invention shown in FIGS. 6 and 7 the radial arms 3 and 4, used in the abovementioned embodiments, are obtained by cutting a thin sheet metal blank in which the slider 2 is shaped by folding and the free end 3a of which has an opening 17 in buttonhole shape obtained by cutting and capable of receiving the ball 8 by elastic snap-fastening.

Dans ce mode de réalisation des bras 3 et 4 le coulisseau 2 est conformé par pliage pour obtenir un profil en forme de U constitué par pliage et contrepliage à 90° d'une partie centrale 2a du flan en tôle à sa partie opposée à l'extrémité libre 3a et constituant la moitié du U d'une part et par pliage et contre pliage à 90° des deux extrémités 2b et 2c situées de part et d'autre de la partie centrale 2a et constituant l'autre moitié du U d'autre part.In this embodiment of the arms 3 and 4 the slider 2 is shaped by folding to obtain a U-shaped profile formed by folding and 90 ° folding of a central part 2a of the sheet metal blank at its part opposite to the free end 3a and constituting half of the U on the one hand and by folding and against 90 ° folding of the two ends 2b and 2c located on either side of the central part 2a and constituting the other half of the U of somewhere else.

Les branches parallèles 2a et 2b, 2c, ainsi constituées coiffent le rebord externe 1 a du boîtier de commande 1, les unes 2b et. 2c étant rabattues contre un rebord inférieur 1b du boîtier 1 et l'autre 2a rabattue également pour constituer un guide 2d apte à coulisser dans le couloir périphérique 10 faisant ainsi office de rail.The parallel branches 2a and 2b, 2c, thus formed cover the outer rim 1a of the control unit 1, some 2b and. 2c being folded down against a lower edge 1b of the housing 1 and the other 2a also folded down to form a guide 2d capable of sliding in the peripheral corridor 10 thus acting as a rail.

La partie libre du guide 2d est orientée vers le fond 10a du couloir périphérique 10 ou rail et constitue avantageusement un peigne dont la denture 2c correspond et s'emboîte dans la denture 18 résultant de la découpe axiale et longitudinale de l'extrémité de l'une quelconque des crémaillères souples 5, 11, 12, 15 ou 16 selon le mode de réalisation choisi, de manière à solidariser l'une de ces dernières au bras en vue de son entraînement. Les peignes 18 et 2e ne pouvant échapper l'un par rapport à l'autre en cours de fonctionnement car la largeur du couloir 10 correspond approximativement à l'épaisseur de la crémaillère.The free part of the guide 2d is oriented towards the bottom 10a of the peripheral corridor 10 or rail and advantageously constitutes a comb whose toothing 2c corresponds and fits into the toothing 18 resulting from the axial and longitudinal cutting of the end of the any of the flexible racks 5, 11, 12, 15 or 16 according to the embodiment chosen, so as to secure one of the latter to the arm for its drive. The combs 18 and 2e cannot escape one relative to the other during operation because the width of the corridor 10 corresponds approximately to the thickness of the rack.

Le mode de réalisation des bras représenté à la fig. 8 diffère essentiellement du précédent en ce que les bras radiaux 3 ou 4 sont obtenus par moulage d'une matière plastique au cours d'une même opération avec le coulisseau 2 et le guide 2d et comportent à leur extrémité libres 3a la rotule 8 avantageusement obtenue de matière avec le bras 3.The embodiment of the arms shown in FIG. 8 differs essentially from the previous in that the radial arms 3 or 4 are obtained by molding a plastic material during the same operation with the slide 2 and the guide 2d and comprise at their free ends 3a the ball 8 advantageously obtained material with the arm 3.

De manière à limiter le vrillage des bras 3 ou 4 suivant leur axe longitudinal, des nervures 19 sont obtenues de moulage sur au moins une des faces desdits bras 3 ou 4. De plus et pour faciliter le débattement en plan desdits bras 3 ou 4 une amorce 20 est prévue à leur base de manière à constituer une charnière.In order to limit the twisting of the arms 3 or 4 along their longitudinal axis, ribs 19 are obtained by molding on at least one of the faces of said arms 3 or 4. In addition and to facilitate the movement in plan of said arms 3 or 4 a primer 20 is provided at their base so as to constitute a hinge.

Il est évident que si les impératifs de moulage l'exigent le guide 2d pourra être rapporté sur le coulisseau 2 par exemple en prévoyant sur le dos du guide 2d, un tenon 21 apte à s'engager dans une mortaise 22 ménagée dans le coulisseau 2 comme figurant dans le mode de réalisation de la fig. 9 ci-après décrit.It is obvious that if the molding requirements require it, the guide 2d can be attached to the slide 2, for example by providing on the back of the guide 2d, a tenon 21 able to engage in a mortise 22 formed in the slide 2 as shown in the embodiment of fig. 9 below described.

Le mode de réalisation des bras représenté à la fig. 9 diffère essentiellement des précédents en ce que les bras radiaux 3 ou 4 sont constitués par une épingle obtenue à partir d'un profilé filiforme à section cylindrique et dont la tête 23 en forme de boutonnière est apte à recevoir la rotule 8.The embodiment of the arms shown in FIG. 9 differs essentially from the previous ones in that the radial arms 3 or 4 are constituted by a pin obtained from a filiform profile with a cylindrical section and whose head 23 in the form of a buttonhole is capable of receiving the ball joint 8.

La rotule 8 comporte à sa partie inférieure une embase 8a obtenue de matière avec elle et munie d'une gorge 8b s'encliquetant élastiquement dans les boutonnières précités. Les branches symétriques 3b et 3c sont pliées à leur extrémité libre suivant un même plan de manière à constituer un axe d'articulation XX' dont chaque partie ainsi constituée sont aptes à être introduit par pincement élastique dans deux paliers correspondants 24 et 25 ménagés de part et d'autre du coulisseau 2 guidant les bras 3 ou 4 sur la périphérie du boîtier de commande 1.The ball joint 8 has at its lower part a base 8a obtained integrally with it and provided with a groove 8b which snaps elastically into the abovementioned buttonholes. The symmetrical branches 3b and 3c are bent at their free end along the same plane so as to constitute a hinge pin XX 'of which each part thus formed is capable of being introduced by elastic pinching in two corresponding bearings 24 and 25 formed on the side and on the other side of the slide 2 guiding the arms 3 or 4 on the periphery of the control box 1.

Selon une autre caractéristique de l'invention (fig. 10) se rapportant plus particulièrement mais non exclusivement aux bras obtenus par découpe d'un flan en tôle fig. 6 ou par moulage fig. 8, lesdits bras sont prolongés vers le centre du boîtier 1 pour tourillonner autour d'un même axe 26 disposé audit centre de manière à assurer aux bras 3 et 4 une retenue plus effective sur le boîtier de commande 1.According to another characteristic of the invention (fig. 10) relating more particularly but not exclusively to the arms obtained by cutting a blank from sheet metal fig. 6 or by molding fig. 8, said arms are extended towards the center of the housing 1 to rotate around the same axis 26 disposed at said center so as to provide the arms 3 and 4 with more effective retention on the control unit 1.

Il est évident que de nombreuses modifications peuvent être apportées à ces modes de réalisation cités à titre d'exemple sans pour cela sortir du cadre de la présente invention, comme par exemple la cinématique peut être conçue de manière telle à ce que la ou les courroies travaillent en poussée pour entraîner la glace dans un mouvement de descente et bénéficier ainsi du poids de celle-ci pour aider le déplacement.It is obvious that many modifications can be made to these embodiments cited by way of example without departing from the scope of the present invention, as for example the kinematics can be designed in such a way that the belt or belts work in thrust to drive the ice in a downward movement and thus benefit from its weight to help the movement.
