Abstract

Headlamp for a motor vehicle, composed of a fixed lens (closure glass) 2 and a reflector 10 which can be moved in rotation with respect to the said lens, in which the lens 2 is directly fixed onto an element 4 of the front face of the vehicle. The lens is furthermore connected to the reflector 10 by means of a flexible seal 13 fixed to the opposing peripheral edges, 14, 15 respectively, of the reflector 10 and of the lens 2, using a permanent connection with one or other of these two edges 14, 15 and using removable assembly 16 with the second of the said peripheral edges.

Description

L'invention concerne les projecteurs pour véhicule automobile et, plus particulièrement, les projecteurs à réflecteur réglable. The invention relates to headlamps for a motor vehicle and, more particularly, headlamps with adjustable reflector.

Les réflecteurs connus de ce type comprennent un boîtier fixé sur la carrosserie du véhicule, une glace montée sur la face avant de ce boîtier et un réflecteur, portant l'équipement électrique, disposé de façon mobile à l'intérieur dudit boîtier. Known reflectors of this type comprise a housing fixed to the body of the vehicle, a lens mounted on the front face of this housing and a reflector, carrying the electrical equipment, disposed movably inside said housing.

Le positionnement de la glace par rapport au boîtier et non directement par rapport à la carrosserie entraîne, en raison des jeux existants, des dispersions au montage pouvant nuire à l'esthétique, notamment, eu égard aux lignes "affleurantes" dictées par les tendances du style actuel des véhicules. En outre, la présence du boîtier réduit, nécessairement, pour une même surface de glace, les dimensions du réflecteur et, par conséquent, son efficacité d'éclairement. The positioning of the glass in relation to the housing and not directly in relation to the bodywork causes, due to the existing play, dispersions during assembly which can adversely affect the aesthetics, in particular, having regard to the "flush" lines dictated by the trends of the current vehicle style. In addition, the presence of the box necessarily reduces, for the same glass surface, the dimensions of the reflector and, consequently, its lighting efficiency.

Ces inconvénients sont résolus par le projecteur selon l'invention, dans lequel la glace est directement fixée sur un élément de la face avant du véhicule. Elle est, en outre, liée au réflecteur, mobile en rotation par rapport à elle, au moyen d'un joint d'étanchéité souple, fixé aux bords périphériques en regard, respectivement du réflecteur et de la glace, au moyen d'une liaison permanente avec l'un ou l'autre de ces deux bords et au moyen d'un assemblage dissociable avec le second. These drawbacks are resolved by the headlight according to the invention, in which the lens is directly fixed to an element on the front face of the vehicle. It is, moreover, linked to the reflector, movable in rotation relative to it, by means of a flexible seal, fixed to the peripheral edges opposite, respectively of the reflector and the glass, by means of a connection. permanent with one or the other of these two edges and by means of a dissociable assembly with the second.

On comprend ainsi que la suppression totale des pièces intermédiaires permet, à la fois, un positionnement précis de la glace par rapport à la carrosserie du véhicule et une utilisation optimale de la surface de cette glace par le réflecteur, tout en assurant, par le joint souple le débattement de la seconde pièce par rapport à la première. It is thus understood that the total elimination of the intermediate parts allows, at the same time, a precise positioning of the glass relative to the body of the vehicle and an optimal use of the surface of this glass by the reflector, while ensuring, by the joint flexible the movement of the second part relative to the first.

Selon un mode de réalisation préférentiel, la glace est constituée de matière plastique.  According to a preferred embodiment, the glass is made of plastic.

On précisera qu'un mode de fixation avantageux de la glace sur l'élément de carrosserie est constitué de pions venus de moulage avec ladite glace. It will be noted that an advantageous method of fixing the glass to the bodywork element is made up of pins from molding with said glass.

Selon d'autres caractéristiques de réalisation
- le joint souple est lié au bord périphérique de l'une
des deux pièces par collage ou soudure aux ultra-sons,
- ledit joint est serré entre le bord périphérique de
l'une des deux pièces et une baguette de clipage montée
sur ledit bord.According to other production characteristics
- the flexible seal is linked to the peripheral edge of one
of the two parts by gluing or ultrasonic welding,
- said seal is clamped between the peripheral edge of
one of the two pieces and a fitted clip rod
on said edge.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre, pour la compréhension de laquelle on se reportera aux dessins annexés, dans lesquels
- La figure 1 est une vue de face partielle de l'avant
d'un véhicule équipé d'un projecteur selon l'invention,
- la figure 2 est une section selon I-I de la figure 1.Other characteristics and advantages of the invention will appear on reading the detailed description which follows, for the understanding of which reference will be made to the accompanying drawings, in which
- Figure 1 is a partial front view of the front
a vehicle fitted with a headlight according to the invention,
- Figure 2 is a section along II of Figure 1.

Sur la figure 2, on voit un projecteur 1 composé d'une glace 2 et d'un réflecteur 10. La glace 2, qui est de préférence réalisée en matière plastique, est munie de pions 3, venus de moulage avec la glace et fixés par clipage dans des ouvertures correspondantes d'une pièce faisant partie de la face avant d'un véhicule automobile, par exemple, sa calandre 4 disposée entre le capot 5 et le pare-choc 6. In Figure 2, we see a headlamp 1 composed of a lens 2 and a reflector 10. The lens 2, which is preferably made of plastic, is provided with pins 3, molded with the lens and fixed by clipping into corresponding openings of a part forming part of the front face of a motor vehicle, for example, its grille 4 disposed between the cover 5 and the bumper 6.

Le réflecteur 10 est monté, de façon connue en soi, dans la structure 11 du véhicule au moyen de fixations 12 permettant son réglage, en site et en azimut. Ces fixations ne seront pas décrites plus en détail, elles pourront être de tout type existant.  The reflector 10 is mounted, in a manner known per se, in the structure 11 of the vehicle by means of fixings 12 allowing its adjustment, in elevation and in azimuth. These fixings will not be described in more detail, they may be of any existing type.

Un joint souple 13 assure l'étanchéité entre le réflecteur et la glace tout en permettant le débattement de l'un par rapport à l'autre. Il est fixé sur la périphérie 14 du réflecteur par collage, par soudure aux ultra-sons ou par tout autre moyen permettant une liaison permanente entre les surfaces des deux éléments. A flexible seal 13 seals between the reflector and the glass while allowing the movement of one relative to the other. It is fixed to the periphery 14 of the reflector by gluing, by ultrasonic welding or by any other means allowing a permanent connection between the surfaces of the two elements.

L'autre extrémité périphérique du joint souple est serrée entre le bord 15 de la glace 2, placé en regard de la périphérie 14 du réflecteur 10, et une baguette 16 clipée sur ledit bord. The other peripheral end of the flexible seal is clamped between the edge 15 of the glass 2, placed opposite the periphery 14 of the reflector 10, and a strip 16 clipped onto said edge.

De cette façon, pour accéder, par exemple, à l'ampoule électrique 17, il suffit de démonter d'abord la baguette 16, ce qui libère le joint 13 et, ensuite la glace 2. In this way, to access, for example, the light bulb 17, it suffices to first dismantle the strip 16, which releases the seal 13 and then the glass 2.

Bien entendu, il est possible d'intervertir les liaisons permanente et dissociable entre le joint souple 13 et les bords périphériques en regard de la glace 2 et du réflecteur 10. Of course, it is possible to reverse the permanent and separable connections between the flexible seal 13 and the peripheral edges facing the glass 2 and the reflector 10.

En variante, encore, la glace 2 peut être fixée sur l'élément de carrosserie par un autre moyen que le clipage, par exemple par vissage. Alternatively, again, the glass 2 can be fixed to the bodywork element by another means than clipping, for example by screwing.

On a ainsi créé, avec un faible nombre de pièces, un projecteur d'encombrement et de poids réduits avec cependant un angle d'éclairement plus important pour une même surface vitrée. En outre, du fait de la fixation directe de la glace sur la carrosserie, les jeux d'affleurement sont réduits au minimum avec les pièces voisines. Cette simplification de conception permet encore d'obtenir des coûts de fabrication peu élevés.  We thus created, with a small number of parts, a spotlight and reduced weight with, however, a greater angle of illumination for the same glass surface. In addition, due to the direct fixing of the glass to the bodywork, the flush clearances are reduced to a minimum with neighboring parts. This simplification of design also makes it possible to obtain low manufacturing costs.
