Abstract

The present invention relates to an extruded elastomer seal including a hairpin-shaped holding part and a tubular sealing part. According to the invention, these two parts are manufactured independently of one another and joined together by clipping means allowing relative sliding of these two parts.

Description

L'invention concerne les joints d'étanchéité en élastomère extrudé, comportant une partie en forme d'épingle qui vient chausser une feuillure pour assurer le maintien du joint et une partie en forme de tube exerçant une fonction d'étanchéité et propre à être comprimée par un élément ouvrant tel qu'une porte, un hayon ou un capot.The invention relates to seals made of extruded elastomer, comprising a pin-shaped part which comes to fit a rebate to ensure the maintenance of the seal and a tube-shaped part exerting a sealing function and suitable for being compressed. by an opening element such as a door, a tailgate or a hood.

Ces joints subissent des déformations dans les zones où la feuillure comporte une courbure et il en résulte des défauts d'étanchéité.These joints undergo deformations in the areas where the rebate has a curvature and this results in sealing defects.

L'invention concerne un joint d'étanchéité de ce type perfectionné de manière à présenter dans les parties courbes une déformation relativement réduite.The invention relates to a seal of this type improved so as to present in the curved parts a relatively reduced deformation.

Ce joint est caractérisé en ce que la partie en forme d'épingle et la partie tubulaire sont fabriquées indépendamment l'une de l'autre et reliées l'une à l'autre par des moyens d'encliquetage permettant un glissement relatif de ces deux parties.This joint is characterized in that the pin-shaped part and the tubular part are manufactured independently of one another and connected to each other by latching means allowing relative sliding of these two parts.

On a décrit ci-après, à titre d'exemple non limitatif, trois modes de réalisation du joint d'étanchéité selon l'invention avec référence au dessin annexé dans lequel les Figures 1 à 3 sont des vues en coupe transversale de ces trois modes de réalisation.Three embodiments of the seal according to the invention have been described below, by way of non-limiting example, with reference to the appended drawing in which FIGS. 1 to 3 are cross-sectional views of these three modes of achievement.

Tel qu'il est représenté à la Figure 1, le joint comprend une partie 1 en forme d'épingle, propre à chausser en butée un bord de tôle 2 pour assurer le maintien du joint, et une partie tubulaire 3 comportant une lèvre d'étanchéité 3a.As shown in Figure 1, the seal includes a pin-shaped part 1, suitable for fitting a sheet metal edge 2 in abutment to maintain the joint, and a tubular part 3 comprising a lip sealing 3a.

Les deux parties 1 et 3 sont encliquetées l'une par rapport à l'autre par des moyens permettant un glissement relatif des deux parties. De manière plus précise, l'épingle 1 présente une partie en saillie la dont la section est en forme de T et qui est disposée dans un logement 4 de la partie 3; cette dernière débouche à l'extérieur par une ouverture 5 dont la largeur est supérieure à celle de la portion de largeur réduite de la partie la mais inférieure à celle de la portion extérieure de grande largeur de cette partie la.The two parts 1 and 3 are snapped relative to each other by means allowing relative sliding of the two parts. More specifically, the pin 1 has a projecting part 1a whose section is T-shaped and which is arranged in a housing 4 of the part 3; the latter opens to the outside through an opening 5 the width of which is greater than that of the reduced width portion of the part 1a but less than that of the large width outer portion of this part 1a.

La partie tubulaire 3 comporte une paroi souple interne 3b séparant le logement 4 de l'espace creux 6 situé du côté de la lèvre 3a. Par ailleurs, elle comporte, de part et d'autre de l'ouverture 5, deux lèvres 3c et 3d s'appuyant de façon étanche sur l'épingle 1.The tubular part 3 has an internal flexible wall 3b separating the housing 4 from the hollow space 6 located on the side of the lip 3a. Furthermore, it comprises, on either side of the opening 5, two lips 3c and 3d pressing in leaktight manner on the pin 1.

Le montage du joint qui vient d'être décrit se fait en enfilant la partie en saillie la dans le logement 4 et en faisant ensuite glisser l'épingle et la partie tubulaire l'une par rapport à l'autre; il peut également se faire en écartant l'un de l'autre les bords de l'ouverture 5 qui, après introduction de la partie la dans le logement 4, viennent s'engager sous la portion extérieure de grande largeur de cette partie la.The mounting of the seal which has just been described is done by threading the projecting part la into the housing 4 and then sliding the pin and the tubular part relative to one another; it can also be done by spreading from one another the edges of the opening 5 which, after introduction of the part la into the housing 4, come to engage under the outer wide portion of this part la.

Lorsque le joint se courbe dans le plan A-A, la génératrice 7 s'allonge par rapport à la génératrice 8 mais cet allongement est réduit, par exemple de 16% au lieu de 40%,dans la cas d'un rayon de 50mm. S'il se courbe dans le plan B-B, le jeu latéral permet à la génératrice 7 de se courber suivant un rayon plus grand que la génératrice 8, ce qui provoque moins de déformations. Cette différence de rayon est directement proportionnelle à la valeur du jeu; on peut ainsi obtenir un gain de 5 à 15% sur l'allongement maximal.When the joint curves in the plane A-A, the generator 7 is extended relative to the generator 8 but this elongation is reduced, for example by 16% instead of 40%, in the case of a radius of 50mm. If it curves in the plane B-B, the lateral play allows the generator 7 to bend along a radius greater than the generator 8, which causes less deformation. This difference in radius is directly proportional to the value of the clearance; we can thus obtain a gain of 5 to 15% on the maximum elongation.

Le joint peut comporter des renforts intérieurs. C'est ainsi que la Figure 2 montre un joint comportant deux renforts 9 et 10 noyés dans la masse respectivement de la paroi 3b et de la partie en saillie la de l'épingle 1.The joint may include internal reinforcements. Thus, FIG. 2 shows a joint comprising two reinforcements 9 and 10 embedded in the mass respectively of the wall 3b and of the projecting part 1a of the pin 1.

Dans le mode de réalisation de la Figure 3, le joint comprend une épingle 11 et une partie tubulaire 12 reliées l'une à l'autre par des moyens d'encliquetage articulés, l'épingle 11 comportant une partie en saillie lla de section circulaire disposée dans un logement 13, également de section circulaire, de la partie 12. La partie lla se raccorde à l'épingle 11 par un col 11b de largeur réduite qui est engagé dans une ouverture 14 du logement 13. La partie 11 comporte par ailleurs des moyens d'encliquetage pour une gaine porte-fils 15, pour un fil de couleur 16 et pour un enjoliveur 17.In the embodiment of Figure 3, the seal comprises a pin 11 and a tubular part 12 connected to each other by articulated latching means, the pin 11 having a projecting part lla of circular section disposed in a housing 13, also of circular section, of the part 12. The part 11a is connected to the pin 11 by a neck 11b of reduced width which is engaged in an opening 14 of the housing 13. The part 11 also comprises latching means for a wire-carrying sheath 15, for a colored wire 16 and for a hubcap 17.

Il va de soi que la présente invention ne doit pas être considérée comme limitée aux modes de réalisation décrits et représentés, mais en couvre, au contraire, toutes les variantes. C'est ainsi notamment que l'élément d'encliquetage mâle pourrait être prévu sur la partie tubulaire du joint et s'engager dans un logement de l'épingle  It goes without saying that the present invention should not be considered as limited to the embodiments described and shown, but on the contrary covers all variants thereof. Thus, in particular, the male latching element could be provided on the tubular part of the seal and engage in a housing for the pin.
