DISPOSITIF A COUSSINETS POUR UN SYSTEME D'ESSUIE-GLACE
A DEUX BRAS ET SYSTEME D'ESSUIE-GLACE EQUIPE D'UN TEL
DISPOSITIF.BEARING DEVICE FOR A WIPER SYSTEM
WITH TWO ARMS AND WINDSCREEN WIPER SYSTEM PROVIDED WITH SUCH
DEVICE.

L'invention est relative t un dispositif å coussinets pour un système d'essuie-glace i deux bras, dispositif du genre de ceux qui comprennent deux manchons cylindriques, sensiblement parallèles, formant coussinets et écartés l'un de l'autre transversalement, chaque manchon étant destine & être traversé par un arbre d'entrainement d'une tête de bras d'essuieglace, les manchons étant destinés å etre fixés sur une structure voisine d'une glace å essuyer, généralement située au-dessous du bord inférieur de cette glace. The invention relates to a pad device for a two-arm wiper system, a device of the type which includes two cylindrical sleeves, substantially parallel, forming pads and spaced apart from each other transversely, each sleeve being intended to be crossed by a drive shaft of a wiper arm head, the sleeves being intended to be fixed on a structure close to a wiping glass, generally located below the lower edge of this ice.

L'invention concerne plus particulièrement, mais non exclusivement, un tel dispositif t coussinets pour système d'essuie-glace de véhicule automobile, en particulier pour le pare-brise du véhicule. The invention relates more particularly, but not exclusively, to such a device for pads for a windscreen wiper system of a motor vehicle, in particular for the vehicle windshield.

On sait que dans l'industrie de grande série, en particulier dans l'industrie automobile, on cherche t réaliser des pièces de plus en plus précises et robustes tout en conservant des couts de production aussi faibles que possible gracie å une conception adaptée. We know that in the mass production industry, in particular in the automobile industry, we seek to produce increasingly precise and robust parts while keeping production costs as low as possible thanks to an adapted design.

L'invention a pour but, surtout, de fournir un dispositif à coussinets qui soit d'une réalisation robuste et suffisamment précise pour assurer un bon positionnement des arbres d'entrafnement traversant les coussinets, tout en restant d'une fabrication simple et économique. The object of the invention is, above all, to provide a bearing device which is of a robust construction and sufficiently precise to ensure correct positioning of the drive shafts passing through the bearings, while remaining simple and economical to manufacture.

Selon l'invention, un dispositif t coussinets pour système d'essuie-glace v deux bras, du genre défini précédemment, est caractérisé par le fait que les deux manchons sont reliés rigidement l'un å l'autre par deux organes de liaison sensiblement parallèles, orientés transversalement par rapport aux hanchons et écartés l'un de l'autre, et qu'une platine, en particulier destinée å supporter un moteur d'essuie-glace, est fixée entre les organes de liaison. According to the invention, a device t pads for wiper system v two arms, of the kind defined above, is characterized in that the two sleeves are rigidly connected to each other by two substantially connecting members parallel, oriented transversely to the hips and spaced from one another, and that a plate, in particular intended to support a wiper motor, is fixed between the connecting members.

De préférence, la platine est fixée par soudure sur lesdits organes de liaison. Preferably, the plate is fixed by welding to said connecting members.

Un organe de liaison est prévu respectivement vers chaque extrémité des manchons. A connecting member is provided respectively towards each end of the sleeves.

Avantageusement, chaque manchon comporte deux appendices transversaux sensiblement parallèles, une extrémité de chaque organe de liaison étant fixée sur un appendice correspondant. Advantageously, each sleeve has two substantially parallel transverse appendages, one end of each connecting member being fixed to a corresponding appendage.

Les appendices peuvent être formés par des éléments cylindriques tandis que les organes de liaison. sont constitués par des tubes cylindriques dans lesquels sont engagés les susdits appendices, la fixation entre les tubes et les appendices étant assurée par tout moyen approprié, tel que sertissage ou soudure. The appendages can be formed by cylindrical elements while the connecting members. consist of cylindrical tubes in which the above appendages are engaged, the fixing between the tubes and the appendages being ensured by any appropriate means, such as crimping or welding.

Selon une autre caractéristique de l'invention, qui peut être utilisée indépendamment ou en combinaison avec les caractéristiques précédentes, un dispositif å coussinets du genre défini précédemment est caractérisé par le fait que les deux manchons cylindriques ont des diamètres intérieurs différents auxquels correspondent des diamètres d'arbres différents pour l'entratnement des bras d'essuie-glaces. According to another characteristic of the invention, which can be used independently or in combination with the preceding characteristics, a device with bearings of the kind defined above is characterized in that the two cylindrical sleeves have different internal diameters to which correspond diameters d '' different shafts for driving the wiper arms.

Cette caractéristique permet de réaliser un detrompage et d'éviter, par exemple, le montage d'un bras porte-balai destiné au coté "conducteur" du coté "passager", ou vice versa. This characteristic makes it possible to make a mistake and to avoid, for example, the mounting of a brush-holder arm intended for the "driver" side of the "passenger" side, or vice versa.

En effet, de plus en plus les bras portebalai "conducteur" et "passager" sur les essuie-glaces de véhicules & deux bras ont des formes et/ou des longueurs différentes ce qui risque, en cas d'inversion de montage, de conduire å des fonctionnelents destructeurs (par exemple interférence en fonctionnement entre les bras porte-balai). In fact, more and more the "driver" and "passenger" wiper arms on vehicle windshield wipers & two arms have different shapes and / or lengths, which could lead to driving in the event of a reverse fitting. å destructive functionalents (for example interference in operation between the brush-carrying arms).

La solution proposée, qui permet d'avoir des arbres de sortie de la timonerie de diamètres différents, permet de réduire les risques de mauvais montage. The proposed solution, which makes it possible to have output shafts of the wheelhouse of different diameters, makes it possible to reduce the risks of incorrect assembly.

L'invention est également relative å un système d'essuie-glace t deux bras, comportant un dispositif à coussinets tel que défini précédemment, chaque bras étant articulé sur une tête destinée å être bloquée par un écrou sur l'extrémité filetée de l'arbre d'entratnement correspondant ; avantageusement, l'écrou de fixation de la tête est monté de manière imperdable sur cette tète. The invention also relates to a wiper system t two arms, comprising a bearing device as defined above, each arm being articulated on a head intended to be blocked by a nut on the threaded end of the corresponding drive shaft; advantageously, the head fixing nut is mounted in a captive manner on this head.

L'écrou peut comporter une embase dont les bords sont engagés dans des rainures de la tète du bras, ledit écrou étant retenu dans ces rainures, notamment par écrasement de l'entrée desdites rainures. The nut may include a base, the edges of which are engaged in grooves in the head of the arm, said nut being retained in these grooves, in particular by crushing the inlet of said grooves.

tans ces conditions, la tête de bras ne peut être montée que sur l'arbre approprié dont l'extrémité filetée a le diamètre correspondant å celui de l'écrou maintenu sur la tête
L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après à propos de modes de réalisation particuliers décrits avec référence au dessin ciannexé, mais qui ne sont nullement limitatifs.under these conditions, the arm head can only be mounted on the appropriate shaft whose threaded end has the diameter corresponding to that of the nut held on the head
The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below in connection with particular embodiments described with reference to the attached drawing, but which are not in no way limiting.

La figure i, de ce dessin, est une vue schématique en perspective d'un dispositif å coussinets, pour système d'essuie-glace a deux bras, conforme à l'invention. Figure i, of this drawing, is a schematic perspective view of a pad device, for two-arm wiper system, according to the invention.

La figure 2 est une vue en perspective, a.  Figure 2 is a perspective view, a.

plus grande échelle, d'une tête de fixation de bras d'essuie-glace en cours d'assemblage avec l'écrou. larger scale, of a wiper arm fixing head being assembled with the nut.

La figure 3, enfin, est une vue partielle, en plan, de la tête de la figure 2 dans laquelle est retenu l'écrou de fixation. Figure 3, finally, is a partial plan view of the head of Figure 2 in which is retained the fixing nut.

En se reportant à la figure 1, on peut voir un dispositif 1 à coussinets pour un système d'essuie-glace E & deux bras 2, 3, partiellement représentés. Referring to Figure 1, one can see a device 1 with bearings for a wiper system E & two arms 2, 3, partially shown.

Le dispositif 1 comprend deux manchons cylindriques 4, 5, sensiblement parallèles, formant coussinets et écartés transversalement l'un de l'autre. Le manchon 4 a un diamètre intérieur (et extérieur) supérieur à celui du manchon 5. The device 1 comprises two cylindrical sleeves 4, 5, substantially parallel, forming pads and spaced transversely from one another. The sleeve 4 has an inside (and outside) diameter greater than that of the sleeve 5.

Chaque manchon 4, 5 est destiné à être traversé par un arbre d'entraînement 6, 7 d'une tête 8, 9 de bras d'essuie-glace 2, 3. L'arbre 6, comme bien visible sur la figure, possède un diamètre externe plus grand que celui de l'arbre 7. Chaque bras est articulé, sur la tête correspondante, autour d'un axe transversal 1~. Des moyens élastiques de rappel (non représentés) sont prévus pour appliquer le bras 2, 3 et le balai contre la surface à essuyer. Each sleeve 4, 5 is intended to be crossed by a drive shaft 6, 7 of a head 8, 9 of wiper arms 2, 3. The shaft 6, as clearly visible in the figure, has an outer diameter larger than that of the shaft 7. Each arm is articulated, on the corresponding head, around a transverse axis 1 ~. Elastic return means (not shown) are provided for applying the arm 2, 3 and the brush against the surface to be wiped.

L'extremite supérieure de l'arbre 6, qui fait saillie, au-del & du coussinet 4, présente une partie tronconique 11, munie de cannelures, prolongée par une partie filetée 12 de p-lus faible diamètre destinée à recevoir un écrou 13 de blocage de la tête 8 sur l'axe 6. La tête 8 comporte un trou 14 à paroi tronconique munie de cannelures conjuguées de celles de la partie 11 de l'arbre. La tête 9 et l'arbre 7 sont agencés d'une manière semblable. The upper end of the shaft 6, which projects beyond the bearing 4, has a frustoconical part 11, provided with grooves, extended by a threaded part 12 of smaller diameter intended to receive a nut 13 for locking the head 8 on the axis 6. The head 8 has a hole 14 with a frustoconical wall provided with grooves conjugated with those of the part 11 of the shaft. The head 9 and the shaft 7 are arranged in a similar manner.

Les manchons 4 et 5 sont destinés & être fixés sur une structure (non représentée) généralement située au-dessous du bord inférieur de la glace à essuyer, en particulier du pare-brise. Pour permettre une telle fixation, chaque manchon 4, 5 comporte une oreille transversale 15, 16 munie d'un trou pour le passage d'une vis de fixation ou équivalent sur ladite structure. The sleeves 4 and 5 are intended to be fixed to a structure (not shown) generally located below the lower edge of the glass to be wiped, in particular of the windshield. To allow such fixing, each sleeve 4, 5 has a transverse lug 15, 16 provided with a hole for the passage of a fixing screw or equivalent on said structure.

Les deux manchons 4, 5 sont reliés rigidement l'un å l'autre par deux organes de liaison 17, 15, sensiblement parallèles, orientes transversalement par rapport auxdits manchons. Les organes 17, 18 sont écartés l'un de l'autre, suivant une direction sensiblement parallèle aux axes des manchons. The two sleeves 4, 5 are rigidly connected to each other by two connecting members 17, 15, substantially parallel, oriented transversely with respect to said sleeves. The members 17, 18 are spaced from each other, in a direction substantially parallel to the axes of the sleeves.

Une platine 19, en particulier destinée å supporter un moteur d'essuie-glace (non représenté), est fixée entre les organes de liaison 17, 18 de manière å servir d'entretoise. La platine 19 est formée par une plaque métallique, sensiblement rectangulaire, munie de bords recourbes propres t s'appliquer contre les organes de liaison 17, 18. La fixation de la platine 19 sur ces organes est avantageusement réalisée par soudure, notamment par points de soudure schématiquement représentés et désignés par la référence numérique 28.  A plate 19, in particular intended to support a wiper motor (not shown), is fixed between the connecting members 17, 18 so as to serve as a spacer. The plate 19 is formed by a metal plate, substantially rectangular, provided with clean curved edges t to be applied against the connecting members 17, 18. The fixing of the plate 19 on these members is advantageously carried out by welding, in particular by points of weld schematically represented and designated by the reference numeral 28.

Chaque manchon 4, 5, comporte deux appendices transversaux sensiblement parallèles 4a, 4b et Sa, 5b prévus respectivement vers chaque extrémité du manchon correspondant. Ces appendices peuvent etre constitués par un élément cylindrique, notamment un morceau de tube soudé sur le manchon associé. Each sleeve 4, 5 has two substantially parallel transverse appendages 4a, 4b and Sa, 5b provided respectively towards each end of the corresponding sleeve. These appendages can be constituted by a cylindrical element, in particular a piece of tube welded on the associated sleeve.

Les organes de liaison 17, 18 sont constitués par des tubes cylindriques dont le diamètre intérieur est tel que les appendices 4a, 4b, Sa, 5b peuvent être engagés, avec un jeu réduit, dans les extrémités correspondantes des organes 17t 18. La fixation entre les organes 17, 18 et les appendices 4a, 4b, Sa, 5b est assurée par tout moyen approprié tel que sertissage ou soudure. The connecting members 17, 18 consist of cylindrical tubes whose internal diameter is such that the appendages 4a, 4b, Sa, 5b can be engaged, with reduced clearance, in the corresponding ends of the members 17t 18. The fixing between the members 17, 18 and the appendices 4a, 4b, Sa, 5b is provided by any suitable means such as crimping or welding.

Les manchons 4, 5, les organes de liaison 17, 18 et la platine 19 constituent un sous-ensemble rigide et robuste, de fabrication simple, permettant d'assurer un guidage précis et efficace des arbres 6 et 7. The sleeves 4, 5, the connecting members 17, 18 and the plate 19 constitute a rigid and robust sub-assembly, of simple manufacture, making it possible to ensure precise and efficient guiding of the shafts 6 and 7.

Le fait que les arbres 6 et 7 aient un diamètre différent, correspondant aux diamètres intérieurs différents des manchons 4 et 5, constitue un système de detrompage imposant de monter sur l'extrémité de l'arbre 6 la tête 8 (et le bras 2 associez munie du trou 14 de diamètre correspondant A celui de l'extrémité de l'arbre 6. Sur l'arbre 7, il convient de monter la tête 9 et le bras associé 3. Le bras 2 et le bras 3 peuvent avoir des longueurs différentes et Entre affectés a un cOté déterminé du pare-brise, par exemple respectivement au cate "pas sager" et au cté "conducteur". The fact that the shafts 6 and 7 have a different diameter, corresponding to the different internal diameters of the sleeves 4 and 5, constitutes a keying system requiring mounting on the end of the shaft 6 the head 8 (and the arm 2 combine provided with the hole 14 of diameter corresponding to that of the end of the shaft 6. On the shaft 7, it is advisable to mount the head 9 and the associated arm 3. The arm 2 and the arm 3 can have different lengths and Between assigned to a specific side of the windshield, for example to the side "not sager" and to the side "driver".

Pour réduire encore les risques de montage erroné, on prévoit de monter l'écrou 13 (voir figure 3) de manière imperdable sur la tête 8. Un montage semblable peut être prévu sur la tête 9.  To further reduce the risks of incorrect mounting, provision is made to mount the nut 13 (see FIG. 3) captively on the head 8. A similar mounting can be provided on the head 9.

L'écrou 13 porte une embase 21 tandis que la tête 8 comporte un logement 22 entourant le trou 14, ce logement s'ouvrant du coté de l'extrémité de la tête opposée au bras. Le logement 22 est bordé par deux rainures 23 dans lesquelles peuvent s'engager des parties diamétralement opposées de l'embase 21, audessous d'un rebord 24 définissant chaque rainure. The nut 13 carries a base 21 while the head 8 has a housing 22 surrounding the hole 14, this housing opening on the side of the end of the head opposite the arm. The housing 22 is bordered by two grooves 23 in which diametrically opposite parts of the base 21 can engage, below a flange 24 defining each groove.

L'écrou 13 est emprisonné dans le, logement 22 par écrasement de chaque rebord 24 au niveau de l'entrée des rainures, comme indiqué par la référence numérique 25 sur la figure 3. Cet écrasement a lieu après que l'embase 21 a été engagée, par coulissement, dans lesdites rainures 23. L'écrou 13 est emprisonné avec une certaine liberté lui permettant de se positionner correctement pour coopérer avec l'extrémité filetée 12 de l'arbre 6. Dans cette configuration, l'écrou 13, tout en étant emprisonné, a la possibilfté de rotation pour son vissage sur l'extrémité filetée. The nut 13 is trapped in the housing 22 by crushing each flange 24 at the entry of the grooves, as indicated by the reference numeral 25 in FIG. 3. This crushing takes place after the base 21 has been engaged, by sliding, in said grooves 23. The nut 13 is trapped with a certain freedom allowing it to be positioned correctly to cooperate with the threaded end 12 of the shaft 6. In this configuration, the nut 13, all while being imprisoned, has the possibility of rotation for its screwing on the threaded end.

Avec ce pontage imperdable de l'écrou 13, il n'est pas possible de monter la tête 8, ayant un diamètre de trou 14 plus important que l'extrémité de l'arbre 7, sur ladite extrémité, puisque l'écrou 13 ne pourra pas se visser sur cette extrémité. Un tel montage erroné aurait été possible en utilisant, avec la tête 8, un écrou adapté ê l'extrémité filetée de l'arbre 7.  With this captive bridging of the nut 13, it is not possible to mount the head 8, having a hole diameter 14 larger than the end of the shaft 7, on said end, since the nut 13 does not cannot be screwed on this end. Such an incorrect assembly would have been possible by using, with the head 8, a nut adapted to the threaded end of the shaft 7.
