Abstract

The seal (9) fits in a recess (14) in one (13) of at least two components (13,15) which are to be sealingly connected. It includes a projection (11) engaging a wall of the recess and is only thereby held in its sealing position. The seal may have a trapezium-shaped cross-section and may be used for sealing the lens (15) and/or the protective housing of a motor vehicle head lamp, a projection (11) being provided on each of the two opposite sides and extending in a direction at right angles to the direction (12) in which it is inserted.

Description

L'invention a pour objet un élément d'étanchéité introduit dans un renfoncement de l'une d'au moins deux parties à réunir. The subject of the invention is a sealing element introduced into a recess in one of at least two parts to be joined.

Dans les phares dits phares à carter, le carter est lié de façon étanche à la glace et au capot de protection par des joints d'étanchéité annulaires profilés, des éléments assurant une fixation amovible. De même, la glace est liée à un châssis porteur au moyen d'un tel joint d'étanchéité profilé, ce châssis porteur étant fixé sur la carrosserie. Lors du montage du phare, le joint d'étanchéité, dont la section est le plus souvent trapézoïdale est collé dans une rainure du carter ou du chassies porteur. In the headlights known as headlights with casing, the casing is linked in an airtight manner to the ice and to the protective cover by profiled annular seals, elements ensuring a removable fixing. Likewise, the glass is linked to a support frame by means of such a profiled seal, this support frame being fixed to the bodywork. When mounting the headlight, the seal, the cross section of which is most often trapezoidal, is glued into a groove in the casing or in the carrier casings.

Lorsqu'on rencontre des circonstances défavorables, notamment si le dispositif de montage pivote ou si l'adhésif n'est pas durci, l'élément d'étanchéité peut se séparer du châssis porteur. Le travail après coup qui en résulte pose des problèmes en raison de la présence de l'adhésif non fixé et ce travail exige une adresse particulière. When adverse circumstances are encountered, especially if the mounting device pivots or if the adhesive is not hardened, the sealing element can separate from the supporting frame. The resulting after-work is problematic due to the presence of the loose adhesive and this work requires a special address.

L'invention a pour but d'éviter cet inconvénient et concerne à cet effet un élément d'étanchéité du type ci-dessus caractérisé en ce que cet élément d'étanchéité présente une saillie s'appliquant sur la paroi du renfoncement de l'élé- ment en maintenant ainsi l'élément d'étanchéité en position de fonctionnement sans faire appel à des moyens étrangers. The object of the invention is to avoid this drawback and for this purpose relates to a sealing element of the above type, characterized in that this sealing element has a projection applying to the wall of the recess of the element. - ment thus maintaining the sealing element in the operating position without using foreign means.

Un tel élément d'étanchéité résoud de manière très simple le problème posé et présente en outre l'avantage de permettre d'économiser l'adhésif et le collage compliqué par le supplément qu'apportent les impropretés. Such a sealing element very simply solves the problem posed and also has the advantage of saving the adhesive and the sticking complicated by the supplement provided by impropretes.

Des dispositions indiquées dans la suite permettent d'obtenir des modes de réalisation avantageux et des perfectionnements de l'élément d'étanchéité conforme à l'invention. Arrangements indicated in the following make it possible to obtain advantageous embodiments and improvements of the sealing element according to the invention.

On obtient un élément d'étanchéité de fabrication simple et de fonctionnement particulièrement sûr en ce qu'une moulure est en saillie sur chacune des deux surfaces latérales de l'élément d'étanchéité, cette moulure s'étendant perpendiculairement à la direction d'introduction de l'élément d'étanchéité. A sealing element of simple manufacture and of particularly safe operation is obtained in that a molding protrudes from each of the two lateral surfaces of the sealing element, this molding extending perpendicular to the direction of introduction. of the sealing element.

Suivant un autre mode de réalisation, la moulure que comporte l'élément d'étanchéité présente une section triangulaire. On obtient ainsi un blocage sflr de l'élément d'étanchéité sur les deux flancs de la rainure. According to another embodiment, the molding that comprises the sealing element has a triangular section. There is thus obtained a blocking sflr of the sealing element on the two sides of the groove.

L'invention sera mieux comprise en regard de la description ci-après et des dessins annexés représentant un exemple de réalisation de l'invention, dessins dans lesquels
- la figure 1 est une vue en perspective à grande échelle d'une partie d'un élément d'étanchéité,
- la figure 2 est une vue correspondante en coupe transversale de l'élément d'étanchéité bloqué dans le châssis porteur.The invention will be better understood with reference to the description below and to the accompanying drawings showing an embodiment of the invention, drawings in which
FIG. 1 is a perspective view on a large scale of part of a sealing element,
- Figure 2 is a corresponding cross-sectional view of the sealing element blocked in the supporting frame.

L'élément d'étanchéité 9 représenté sur la figure 1 est constitué par un cordon formé par extrusion en matière élastique telle que caoutchouc ou matière thermoplasti- que. Cet élément présente une section trapézoldale avec une moulure 11 en saillie sur chacune des deux surfaces latérales 10. Cette moulure présente une section triangulaire allant en diminuant vers ltextérieur. On forme un anneau d'étanchéité en réunissant les deux extrémités, non représentées, du cordon. The sealing element 9 shown in FIG. 1 is constituted by a bead formed by extrusion from an elastic material such as rubber or thermoplastic material. This element has a trapezoidal section with a molding 11 projecting from each of the two lateral surfaces 10. This molding has a triangular section which tapers towards the inside. A sealing ring is formed by joining the two ends, not shown, of the cord.

Chaque moulure 11 s'étend transversalement à la direction d'introduction de l'anneau d'étanchéité indiquée par une flèche 12.Each molding 11 extends transversely to the direction of introduction of the sealing ring indicated by an arrow 12.

La figure 2 représente une partie du châssis porteur 13 d'un phare de véhicule automobile, ce châssis cpmportant une rainure 14 dont les deux flancs sont divergents vers l'extérieur. On a représenté une partie de la base d'une glace 15. FIG. 2 represents a part of the carrying frame 13 of a headlight of a motor vehicle, this frame having a groove 14 whose two sides are diverging towards the outside. A part of the base of a mirror 15 has been shown.

L'eTément d'étanchéité 9 est enfoncé suivant la direction de la flèche 12 dans la rainure annulaire 14 et prend sa position de fonctionnement. L'introduction de l'élément d'étanchéité 9 augmente la force d'application des deux moulures 1t, de telle sorte que la force de retenue ainsi développée suffit pour maintenir l'élément d'étanchéité 9 dans le châssis porteur 13 sans faire appel à des moyens étrangers. The sealing element 9 is pressed in the direction of the arrow 12 into the annular groove 14 and assumes its operating position. The introduction of the sealing element 9 increases the application force of the two moldings 1t, so that the retaining force thus developed is sufficient to hold the sealing element 9 in the supporting frame 13 without calling upon to foreign means.
