Abstract

The sealing strip is designed to consist of an external part (2) and an internal part (1). Between the two parts, a U-shaped groove (G) is formed. The groove encloses and seals the edge (3a) of the glass panel (3), when it is in the closed position. The internal section of the profile of the sealing strip, carries a pair of lips (10,11), which are in contact with the internal face of the glass panel as it moves into the closed position. The inner lip (11) is designed to be deflected by the glass panel to come into contact with a stop lip (12). The stop lip protrudes from the outer bridge section (21), of the profile, which joins the internal and external sections together. The stop lip is designed and located to cause the glass panel to move, as it closes, towards the external section of the sealing strip.

Description

La présente invention concerne un joint d'étanchéité pour vitres coulissantes de véhicule automobile. Les joints de ce type appelés également coulisses comprennent généralement une partie externe et une partie interne délimitant entre elles une gorge en U dans laquelle est emprisonné le bord périphérique de la vitre dans sa position de fermeture. The present invention relates to a seal for sliding windows of a motor vehicle. Seals of this type also called slides generally comprise an external part and an internal part delimiting between them a U-shaped groove in which the peripheral edge of the glass is trapped in its closed position.

Cependant, pour des vitres affleurantes à la carrosserie, il peut sc produire un décalage transversal vers l'intérieur de l'habitacle de la partie supérieure de la vitre. Cest le cas notamment, lorsque la fermeture est effectuée avec le véhicule en route sous l'effet de la dépression interne résultant de la vitesse. However, for windows flush with the body, it may produce a transverse shift towards the interior of the passenger compartment of the upper part of the window. This is particularly the case, when the closure is carried out with the vehicle on the road under the effect of the internal depression resulting from the speed.

Ce décalage compromet l'étanchéité de la fermeture et provoque, par ailleurs des bruits inconfortables (sifflements....) à vitesse élevée. This offset compromises the tightness of the closure and also causes uncomfortable noises (hissing ...) at high speed.

En outre, les jeux de fabrication du système de lèvc-vitres introduisent déjà un débattement de la partie inférieure de la vitre qui combiné au fait que la partie supérieure n'est pas tenue fermement, entraîne des vibrations importantes. In addition, the manufacturing games of the window-lift system already introduce a movement of the lower part of the glass which combined with the fact that the upper part is not held firmly, causes significant vibrations.

La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante. The present invention aims to solve these technical problems satisfactorily.

Ce but est atteint au moyen d'un joint d'étanchéité pour vitres coulissantes de véhicule automobile comprenant une partie externe et une partie interne délimitant entre elles une gorge en U dans laquelle est emprisonné de manière étanche le bord périphérique de la vitre dans sa position de fermeture, ladite partie interne porte une lèvre de déviation destinée à venir en contact d'appui, d'une part avec la face interne de la vitre et d'autre part avec un butoir de façon à provoquer le déportement latéral de ladite vitre vers l'extérieur lors de la fermeture quelque soit l'allure du véhicule. This object is achieved by means of a seal for sliding windows of a motor vehicle comprising an external part and an internal part delimiting between them a U-shaped groove in which the peripheral edge of the glass is trapped in a sealed manner. closing, said internal part carries a deflection lip intended to come into bearing contact, on the one hand with the internal face of the glass and on the other hand with a stopper so as to cause the lateral offset of said glass towards outside when closing whatever the speed of the vehicle.

Selon une caractéristique avantageuse, ledit butoir est constitué d'une lèvre rigide solidaire du fond de ladite gorge. According to an advantageous characteristic, said stopper consists of a rigid lip secured to the bottom of said groove.

Selon une autre caractéristique, ladite lèvre de déviation est formée d'un tronçon rigide de rattachement avec la partie interne, se prolongeant via une articulation par un tronçon curviligne souple de contact avec la vitre. According to another characteristic, said deflection lip is formed of a rigid section of attachment with the internal part, extending via an articulation by a flexible curvilinear section of contact with the glass.

De préférence, le tronçon de liaison de la lèvre de déviation est disposé dans le prolongement axial du butoir. Preferably, the connecting section of the deflection lip is disposed in the axial extension of the stopper.

Selon un mode de réalisation particulier, ladite lèvre de déviation et ledit butoir ont des faces en regard à profils complémentaires.  According to a particular embodiment, said deflection lip and said stopper have opposite faces with complementary profiles.

Selon un autre mode de réalisation, la zone de jonction de la partie inteme au fond de la gorge en U comporte une échancrure permettant le montage sous tension du joint dans son logement. According to another embodiment, the junction zone of the internal part at the bottom of the U-shaped groove has a notch allowing the assembly under tension of the seal in its housing.

Selon encore une autre caractéristique, ladite lèvre de déviation, ledit butoir, la partie inteme et le fond de la gorge délimitent entre eux un compartiment obturable de façon étanche par le bord de la vitre. According to yet another characteristic, said deflection lip, said stopper, the internal part and the bottom of the groove define between them a compartment which can be sealed off by the edge of the glass.

Le joint de la présente invention permet un positionnement correct de la vitre pendant la phase finale de la fermeture quelque soit l'allure du véhicule. The seal of the present invention allows correct positioning of the window during the final phase of closing whatever the speed of the vehicle.

Grâce au compartiment obturable réalisé au fond de la gorge en U, il apporte, en outre, une barrière supplémentaire aux entrées d'eau et d'air. Il offre un moyen simple et économique pour rattraper et limiter le jeu transversal entre la face extérieure de la vitre affleurante et la face extérieure du joint. Il contribue ainsi à améliorer l'aspect esthétique de la portière. Thanks to the closable compartment made at the bottom of the U-shaped groove, it also provides an additional barrier to the entry of water and air. It offers a simple and economical way to make up for and limit the transverse play between the outer face of the flush glass and the outer face of the seal. It thus contributes to improving the aesthetic appearance of the door.

L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée des dessins sur lesquels:
la figure 1 représente une vue en coupe verticale du joint de l'invention en position d'ouverture de la vitre.The invention will be better understood on reading the description which follows, accompanied by the drawings in which:
Figure 1 shows a vertical sectional view of the seal of the invention in the open position of the glass.

la figure 2 représente une vue en coupe verticale du joint de la figure 1 en position de fermeture de la vitre. 2 shows a vertical sectional view of the seal of Figure 1 in the closed position of the window.

Le joint représenté sur les figures 1 et 2 comprend une partie interne 1 et une partie externe 2 délimitant entre elles une gorge G en U dans laquelle est emprisonné de manière étanche le bord périphérique de la vitre 3 et ici en particulier le bord supérieur 3a dans la position de fermeture représentée sur la figure 2. The seal shown in FIGS. 1 and 2 comprises an internal part 1 and an external part 2 delimiting between them a groove G in a U in which the peripheral edge of the window 3 is trapped in a sealed manner and here in particular the upper edge 3a the closed position shown in Figure 2.

A cet effet, la partie interne 1 est pourvue d'une lèvre d'étanchéité 10 venant en appui contre la face intérieure de la vitre 3 et la partie externe 2 porte au moins une lèvre d'étanchéité 20 venant en appui contre la face extérieure de ladite vitre
Les faces de contact des lèvres d'étanchéité 10, 20 sont de préférence revêtues d'un matériau glissant.For this purpose, the internal part 1 is provided with a sealing lip 10 coming to bear against the internal face of the window 3 and the external part 2 carries at least one sealing lip 20 coming to bear against the external face of said window
The contact faces of the sealing lips 10, 20 are preferably coated with a sliding material.

La partie interne 1 porte, en outre, une lèvre de déviation 11 destinée à venir en contact d'appui avec d'une part, la face intérieure de la vitre 3 et d'autre part, avec un butoir 12 de façon à provoquer le déportement latéral de la vitre 3 vers l'extérieur lors de la fermeture (voir figure 2) et ceci quelque soit l'allure du véhicule.  The internal part 1 carries, moreover, a deflection lip 11 intended to come into bearing contact with on the one hand, the internal face of the window 3 and on the other hand, with a stopper 12 so as to cause the lateral offset of the window 3 towards the outside during closing (see FIG. 2) and this regardless of the speed of the vehicle.

Le butoir 12 est constitué d'une lèvre solidaire du fond 21 de la gorge G qui assure la liaison entre les parties interne 1 et externe 2. La lèvre de déviation 11 est formé d'un tronçon lla, assurant le rattachement avec la partie inteme 1. Le tronçon lia se prolonge via une articulation îlb, par un tronçon souple lic, à profil curviligne lic, assurant le contact avec la vitre 3. The stopper 12 consists of a lip integral with the bottom 21 of the groove G which provides the connection between the internal parts 1 and external 2. The deflection lip 11 is formed of a section lla, ensuring the connection with the internal part 1. The section 11a is extended via an articulation îlb, by a flexible section lic, with a curvilinear profile lic, ensuring contact with the window 3.

Le tronçon de rattachement lia est disposé dans le prolongement axial du butoir 12 tandis que le tronçon de contact llc fait saillie, en position d'ouverture de la vitre 3, vers l'intérieur et en direction du fond 21 de la gorge G. The connecting section 11a is arranged in the axial extension of the stopper 12 while the contact section llc protrudes, in the open position of the window 3, inwards and in the direction of the bottom 21 of the groove G.

La lèvre de déviation 11 et en particulier son tronçon de contact lic ainsi que le butoir 12 ont des faces en regard dont les profils sont complémentaires. The deflection lip 11 and in particular its lic contact section as well as the stopper 12 have opposite faces whose profiles are complementary.

Cette disposition permet d'obtenir d'une part, un calage satisfaisant du bord périphérique 3a de la vitre 3 en position de fermeture et, d'autre part, une étanchéité supplémentaire à l'air et à l'eau.This arrangement makes it possible on the one hand to obtain satisfactory wedging of the peripheral edge 3a of the window pane in the closed position and, on the other hand, an additional air and water tightness.

En effet, le butoir 12, la lèvre de déviation 11, la partie interne 1 et le fond 21 de la gorge G délimitent entre eux, un compartiment C, obturable de façon étanche par déformation de la lèvre 11 qui vient en contact avec le butoir 12 sous l'action du bord 3a de la vitre 3. Indeed, the stopper 12, the deflection lip 11, the internal part 1 and the bottom 21 of the groove G delimit between them, a compartment C, which can be closed in leaktight manner by deformation of the lip 11 which comes into contact with the stopper 12 under the action of the edge 3a of the window 3.

Pour effectuer le montage du joint dans son logement sur la feuillure de carrosserie (non représentée) et sous tension, la zone de jonction de la partie interne 1 avec le fond 21 de la gorge G comporte une échancrure 22. To mount the seal in its housing on the body rebate (not shown) and under tension, the junction zone of the internal part 1 with the bottom 21 of the groove G has a notch 22.

Comme représenté sur la figure 2, lors de la montée de la vitre 3, le bord supérieur 3a vient en contact d'appui contre le tronçon lic de la lèvre de déviation 11. Comme le tronçon 1 la de rattachement de la lèvre 1 i est rigide, la montée de la vitre 3 a pour effet de repousser le tronçon lic contre le butoir 12. As shown in FIG. 2, when the window 3 is raised, the upper edge 3a comes into bearing contact against the lic section of the deflection lip 11. Like the section 1 la for connecting the lip 1 i is rigid, the rise of the window 3 has the effect of pushing the lic section against the stopper 12.

La rigidité du butoir 12 est suffisante pour résister à l'effort de déformation de la vitre 3, et c'est finalement la vitre elle-même qui va se déporter transversalement vers l'extérieur en profitant du léger jeu autorisé par ses guidages verticaux et le lève-vitre. The rigidity of the stopper 12 is sufficient to withstand the deformation force of the window 3, and it is ultimately the window itself which will move transversely outward, taking advantage of the slight clearance allowed by its vertical guides and the window regulator.

La lèvre d'étanchéité extérieure 20 reçoit alors la vitre 3 en appui et se déforme élastiquement, essentiellement en compression. La vitre 3 se trouve alors dans une position de fermeture décalée, d'une distance d par rapport à sa position d'ouverture.  The outer sealing lip 20 then receives the window 3 in abutment and deforms elastically, essentially in compression. The window 3 is then in an offset closed position, by a distance d from its open position.

L'invention n'est pas limitée à la réalisation décrite, mais en couvre au contraire toutes les variantes qui pourraient lui être apportées sans sortir de son cadre, ni de son esprit.  The invention is not limited to the embodiment described, but on the contrary covers all the variants which could be made to it without departing from its scope or its spirit.
