D'autres particularités et avantages apparaîtront à la 35 lecture de la description ci-après faite en référence aux figures dans lesquelles : - la figure 1 représente une vue en perspective de la façade avant d'un véhicule automobile, - la figure 2 représente une vue identique à la figure 1, la façade étant dépourvue de ses projecteurs et de son pare-chocs, - les figures 3 et 4 montrent des détails de la fixation de l'armature de pare-chocs, supportant le pare-chocs représenté à la figure 1, respectivement sur un élément de liaison fixé à la structure du véhicule et sur une platine destinée à supporter io la poutre de pare-chocs, Other features and advantages will appear on reading the following description made with reference to the figures in which: - Figure 1 shows a perspective view of the front of a motor vehicle, - Figure 2 shows a identical view to Figure 1, the facade being devoid of its projectors and its bumper, - Figures 3 and 4 show details of the attachment of the bumper frame, supporting the bumper shown in the 1, respectively on a connecting element fixed to the vehicle structure and on a plate for supporting the bumper beam,
- la figure 5 représente une vue en perspective de la zone encerclée A à la figure 2. FIG. 5 represents a perspective view of the encircled zone A in FIG. 2.
15 La figure 1 représente la façade avant 2 d'un véhicule automobile, qui comprend de façon classique, un pare-chocs 1 en matière plastique, des ailes latérales 11, un capot 5 et des projecteurs 9. FIG. 1 shows the front face 2 of a motor vehicle, which conventionally comprises a plastic bumper 1, side wings 11, a cover 5 and projectors 9.
20 La partie supérieure du pare-chocs 1 est fixée sur une armature 4, communément appelée armature de pare-chocs . La partie inférieure du pare-chocs 1 est supportée par une poutre de pare-chocs 7 (voir la figure 2). The upper part of the bumper 1 is fixed on a frame 4, commonly called a bumper frame. The lower part of the bumper 1 is supported by a bumper beam 7 (see Figure 2).
25 La poutre de pare-chocs 7 comprend - une traverse 71 qui s'étend transversalement au véhicule et - deux branches longitudinales 72, qui prolongent la traverse 71 vers l'arrière au voisinage de ses 30 extrémités latérales, et qui se terminent par des platines 8 de fixation aux longerons (non représentés), appartenant à la structure du véhicule. Chaque branche longitudinale 72 comprend un absorbeur d'énergie. 35 5 La platine 8 comprend un corps 82 disposé de façon sensiblement perpendiculaire à l'axe longitudinal du véhicule et une patte 81 pliée, disposée de façon sensiblement perpendiculaire au corps 82. L'armature 4 est une pièce en matière plastique, possédant un axe de symétrie vertical. L'armature 4 s'étend au-dessus de la traverse 71. Ses extrémités latérales servent de support et permettent la fixation des projecteurs 9. io L'armature 4 comprend dans sa partie inférieure deux jambes 43, 44 s'étendant, selon l'axe Z, de façon sensiblement perpendiculaire à l'axe longitudinal du véhicule. Ces jambes 43, 44 sont venus de matière avec le corps de l'armature 4, mais elles peuvent également être des pièces rapportées 15 fixées sur le corps de l'armature. Les jambes 43, 44 sont positionnées dans la partie centrale de l'armature 4, de préférence, de part et d'autre de l'axe de symétrie de l'armature 4. Elles sont destinées à venir en appui sur la traverse 71. Ainsi les jambes 43, 44 sont 20 également positionnées de part et d'autre de l'axe de symétrie vertical de la traverse 71. The bumper beam 7 comprises - a cross-member 71 which extends transversely to the vehicle and two longitudinal branches 72, which extend the cross-member 71 rearwards in the vicinity of its lateral ends, and which terminate in plates 8 for attachment to the longitudinal members (not shown), belonging to the structure of the vehicle. Each longitudinal branch 72 comprises an energy absorber. The plate 8 comprises a body 82 disposed substantially perpendicular to the longitudinal axis of the vehicle and a folded tab 81, disposed substantially perpendicular to the body 82. The armature 4 is a plastic part, having an axis of vertical symmetry. The armature 4 extends above the cross member 71. Its lateral ends serve as a support and allow the fixing of the projectors 9. The armature 4 comprises in its lower part two legs 43, 44 extending, according to the Z axis, substantially perpendicular to the longitudinal axis of the vehicle. These legs 43, 44 are integral with the body of the frame 4, but they can also be inserts 15 fixed to the body of the frame. The legs 43, 44 are positioned in the central part of the armature 4, preferably on either side of the axis of symmetry of the armature 4. They are intended to rest on the crossmember 71. Thus the legs 43, 44 are also positioned on either side of the vertical axis of symmetry of the crossmember 71.
Chaque jambe 43, 44 possède une surface d'appui 43a, 44a, destinée à reposer sur la partie supérieure de la traverse 25 71a, prolongée par une patte 43b, 44b en saillie venant en butée contre le côté latéral de la traverse 71 b, orienté du côté du pare-chocs 1. Each leg 43, 44 has a bearing surface 43a, 44a, intended to rest on the upper part of the crossmember 71a, extended by a tab 43b, 44b protruding abutting against the lateral side of the crossbar 71b, oriented on the side of the bumper 1.
Ainsi, l'armature 4 est en appui sur la traverse 71 ce qui 30 amène de la raideur dans la zone située entre la traverse 71 et l'armature 4. Ceci a pour effet de limiter, en cas de choc, l'affaissement de l'armature 4 sur la traverse 71. Bien sûr, d'autres moyens de maintien peuvent être disposés entre l'armature 4 et la traverse 71. 35 Les extrémités de l'armature 4 comportent notamment : - une branche 41 destinée à recevoir la partie inférieure du projecteur 9 et - une paroi latérale 42 destinée à recevoir une partie d'une paroi latérale du projecteur 9. Thus, the armature 4 is supported on the cross-member 71 which causes stiffness in the zone situated between the cross-member 71 and the armature 4. This has the effect of limiting, in the event of an impact, the sagging of the armature 4 on the crossbar 71. Of course, other holding means may be arranged between the frame 4 and the cross member 71. The ends of the frame 4 comprise in particular: a branch 41 intended to receive the lower part of the projector 9 and - a side wall 42 intended to receive part of a side wall of the projector 9.
Chaque extrémité de la paroi latérale 42 est fixée sur l'extrémité 61 d'un élément de liaison 6 positionné sur la structure du véhicule, par exemple au moyen de vis 12 (voir la figure 3). Cet élément 6 de liaison est communément appelé io équerre appui de façade , il permet également de positionner une pièce transversale 3 supportant des éléments de refroidissement du moteur du véhicule, communément appelée façade technique , par rapport à la structure du véhicule. La partie supérieure de l'armature 4 est également 15 fixée sur la façade technique 3. Each end of the side wall 42 is fixed on the end 61 of a connecting element 6 positioned on the vehicle structure, for example by means of screws 12 (see Figure 3). This connecting element 6 is commonly called io bracket square front, it also allows to position a transverse part 3 supporting cooling elements of the vehicle engine, commonly known as technical front, relative to the vehicle structure. The upper part of the frame 4 is also fixed on the technical front 3.
Selon l'invention, chaque branche 41 est fixée sur la patte 81 de la platine 8 (voir la figure 4), par exemple, au moyen de vis 13. Bien sûr, tout autre moyen de fixation adapté peut être 20 utilisé. According to the invention, each leg 41 is fixed to the tab 81 of the plate 8 (see FIG. 4), for example, by means of screws 13. Of course, any other suitable fixing means can be used.
Selon d'autres modes de réalisation, chaque branche 41 peut être fixée sur une surface aménagée de la branche latérale 72 comprenant l'absorbeur d'énergie ou sur l'extrémité 25 de la traverse 71. According to other embodiments, each branch 41 can be fixed on a fitted surface of the lateral branch 72 comprising the energy absorber or on the end 25 of the cross member 71.
Grâce à l'invention, l'armature 4 est solidement fixée, ce qui assure sa stabilité géométrique et évite la rotation de l'armature. La fixation de l'extrémité de la paroi latérale 42 sur 30 l'équerre appui de façade 6 et les jambes 43, 44 disposées entre la traverse 71 et l'armature 4 permettent d'accroître cette stabilité. Thanks to the invention, the armature 4 is securely fixed, which ensures its geometric stability and prevents rotation of the armature. Attaching the end of the side wall 42 to the front support bracket 6 and the legs 43, 44 disposed between the cross member 71 and the frame 4 increase this stability.
