Description

La présente invention a essentiellement pour objet un pare-chocs pour véhicule automobile quelconque de tourisme ou utilitaire. The present invention essentially relates to a bumper for any passenger or utility motor vehicle.

Il a déjà été proposé de nombreuses réalisations de pare-chocs avant et/ou arrière pour les vehicules automobiles. Numerous embodiments of front and / or rear bumpers for motor vehicles have already been proposed.

D'une manière générale, les pare-chocs connus donnent satisfaction sur le plan de l'absorption des chocs, mais leur fabrication demeure relativement compliquée et coûteuse. In general, the known bumpers are satisfactory in terms of shock absorption, but their manufacture remains relatively complicated and expensive.

En effet, ces pare-chocs connus sont généralement composés de plusieurs pièces qu'il convient d'assembler et qui nécessitent parfois sur le véhicule la prévision de pièces supplémentaires spéciales permettant une fixation et un fonctionnement appropriés du pare-chocs. Indeed, these known bumpers are generally composed of several parts which should be assembled and which sometimes require on the vehicle the provision of special additional parts allowing proper fixing and operation of the bumper.

Aussi, la présente invention a pour but de remédier à ces inconvénients en proposant un pare-chocs qui se compose d'un nombre de pièces minimal, et qui est donc peu coûteux à concevoir et à fabriquer, sans pour cela affecter les qualités de résistance et d'absorption des chocs qu'il doit nécessairement comporter. Also, the present invention aims to remedy these drawbacks by proposing a bumper which consists of a minimum number of parts, and which is therefore inexpensive to design and manufacture, without thereby affecting the strength qualities. and shock absorption that it must necessarily involve.

A cet effet, l'invention a pour objet un pare-chocs pour véhicule automobile essentiellement caractérisé en ce qu'il constitue une pièce unique obtenue par moulage et comprenant une poutre présentant en section transversale sensiblement la forme d'un U dont l'extrémité des branches se prolonge par des ailes s'étendant de part et d'autre du U pour former un bouclier. To this end, the subject of the invention is a bumper for a motor vehicle essentially characterized in that it constitutes a single part obtained by molding and comprising a beam having in cross section substantially the shape of a U whose end branches are extended by wings extending on either side of the U to form a shield.

Ce pare-chocs est encore caractérisé en ce que la partie ouverte du U de la poutre est obturable par un bandeau rapporte. This bumper is further characterized in that the open part of the U of the beam is closable by an attached strip.

Ainsi, l'esthétique du pare-chocs sera assurée. Thus, the aesthetics of the bumper will be ensured.

Selon encore une autre caractéristique du pare-chocs de l'invention, des nervures verticales et/ou horizontales sont situées à l'intérieur du U de la poutre et viennent de moulage avec elle et le bouclier, lors de la fabrication du pare-chocs.  According to yet another characteristic of the bumper of the invention, vertical and / or horizontal ribs are located inside the U of the beam and come from molding with it and the shield, during the manufacture of the bumper .

On précisera encore ici que la pièce unique constituée par la poutre en U, le bouclier et les nervures est avantageusement réalisée en une matière plastique moulée. It will also be specified here that the single part constituted by the U-shaped beam, the shield and the ribs is advantageously made of a molded plastic.

Mais d'autres avantages et caractéristiques de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels
- la figure 1 est une demi-vue en perspective du parechocs de cette invention avec son bandeau représenté en position non montée
- la figure 2 est une vue en coupe suivant la ligne II II de la figure 1 ; et
- la figure 3 est une vue schématique en plan et de dessus du pare-chocs en position montée sur les brancards avant d'un véhicule automobile.
However, other advantages and characteristics of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example, and in which
- Figure 1 is a half perspective view of the bumper of this invention with its strip shown in the unassembled position
- Figure 2 is a sectional view along line II II of Figure 1; and
- Figure 3 is a schematic plan view from above of the bumper in the mounted position on the front stretchers of a motor vehicle.

On voit sur les figures 1 et 2 qu'un pare-chocs conforme à cette invention est essentiellement constitué par une pièce unique 1 qui est de préférence réalisée par moulage d'une matière plastique appropriée, cette pièce unique se composant d'une poutre 2 à laquelle est intégré un bouclier 3. We see in Figures 1 and 2 that a bumper according to this invention is essentially constituted by a single piece 1 which is preferably made by molding of a suitable plastic, this single piece consisting of a beam 2 to which a shield is integrated 3.

Plus précisément, la poutre 2, comme cela est bien visible sur les figures, présente en section transversale la forme générale d'un U dont les branches ont été repérées en 4. L'extrémité des branches 4 se prolonge par des ailes 5 qui s'étendent de chaque côté du U de la poutre 2 pour former le bouclier 3. More specifically, the beam 2, as is clearly visible in the figures, has in cross section the general shape of a U whose branches have been identified at 4. The end of the branches 4 is extended by wings 5 which are 'extend on each side of the U of the beam 2 to form the shield 3.

Ce bouclier 3 constitué par les ailes 5 peut présenter une forme appropriée quelconque, pour tenir compte des propriétés que doit comporter le pare-chocs, à savoir notamment des propriétés d'absorption des chocs, d'aérodynamisme par rapport à la carrosserie du véhicule, d'esthétique, etc. Ainsi, comme on le voit sur la figure 2, les deux ailes 5 peuvent avoir des formes différentes en section transversale et s'étendre, quant à leurs extrémités, plus ou moins vers l'arrière, ctest-à-dire en direction du fond du U que constitue la poutre 2.  This shield 3 consisting of the wings 5 may have any suitable shape, to take account of the properties which the bumper must include, namely in particular shock absorption properties, aerodynamics with respect to the vehicle body, aesthetics, etc. Thus, as can be seen in FIG. 2, the two wings 5 can have different shapes in cross section and extend, as regards their ends, more or less towards the rear, that is to say towards the bottom. of the U that constitutes the beam 2.

On a montré en 6 sur les figures 1 et 2 un bandeau, de préférence en matière plastique, qui est rapporté et fixé sur la pièce unique moulée 1 décrite ci-dessus de façon à obturer l'ouverture du U de la poutre 2. A strip, preferably made of plastic, has been shown at 6 in FIGS. 1 and 2, which is attached and fixed to the single molded part 1 described above so as to close the opening of the U of the beam 2.

Ce bandeau 6 pourra être fixé, par clippage par exemple, sur les ailes 5 formant le bouclier 3. This strip 6 can be fixed, for example by clipping, on the wings 5 forming the shield 3.

A l'intérieur du U que forme la poutre 2 sont prévues des nervures verticales et sensiblement parallèles 7 assurant le raidissement de la poutre. Il pourrait parfaitement être prévu, sans sortir du cadre de l'invention, des nervures suivant un autre agencement, par exemple des nervures horizontales ou encore une combinaison de nervures verticales et horizontales. Inside the U formed by the beam 2 are provided vertical and substantially parallel ribs 7 ensuring the stiffening of the beam. It could perfectly be provided, without departing from the scope of the invention, ribs according to another arrangement, for example horizontal ribs or a combination of vertical and horizontal ribs.

Ces nervures viendront de préférence de moulage avec la pièce unique 1 constituant la poutre en U 2 et le bouclier 3 formé des deux ailes 5 prenant naissance aux extrémités des branches 4 du U. These ribs will preferably come from molding with the single part 1 constituting the U-shaped beam 2 and the shield 3 formed of the two wings 5 originating at the ends of the branches 4 of the U.

On voit sur la figure 3 que le pare-chocs de cette invention qui vient d'être décrit peut par exemple constituer un pare-chocs avant fixé par tout moyen approprié aux extrémités des brancards 8 d'un véhicule automobile (non représenté). Dès lors, dans un tel cas où le pare-chocs travaille en flexion sur deux appuis, il n'est aucunement nécessaire de prévoir des pièces supplémentaires de fixation ou d'appui. En d'autres termes, la rigidité du pare-chocs de cette invention est suffisante pour satisfaire les normes requises actuellement en matière de sécurité automobile. It can be seen in FIG. 3 that the bumper of this invention which has just been described can for example constitute a front bumper fixed by any suitable means to the ends of the stretchers 8 of a motor vehicle (not shown). Therefore, in such a case where the bumper works in bending on two supports, it is in no way necessary to provide additional fixing or support parts. In other words, the rigidity of the bumper of this invention is sufficient to meet the standards currently required in terms of automobile safety.

On a donc réalisé suivant l'invention un pare-chocs pour véhicule automobile qui est d'une conception simple et peu coûteux à fabriquer sans pour cela nuire aux qualités qu'il doit nécessairement avoir compte tenu de la réglementation actuelle. A bumper for a motor vehicle has therefore been produced according to the invention, which is of a simple design and inexpensive to manufacture, without thereby harming the qualities which it must necessarily have given the current regulations.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.

C'est ainsi que les nervures verticales 7 pourront comporter des encoches ou évidements 9 pour le passage d'équipements tels que des fils électriques ou des tuyaux, étant entendu que ces nervures pourront revêtir une forme quelconque. Thus the vertical ribs 7 may include notches or recesses 9 for the passage of equipment such as electrical wires or pipes, it being understood that these ribs may take any form.

C'est dire que l'invention comprend tous fes équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.  This means that the invention includes all the technical equivalents of the means described as well as their combinations if these are carried out according to the spirit.
