Description
DISPOSITIF PARE-CHOCS DE VEHICULE AUTOMOBILE
L'invention concerne un dispositif parechocs de véhicule automobile constitué par une coque extérieure qui s'étend transversalement et latéralement devant la carrosserie et qui -de des lames horizontales parallUes de renforcement raccordées à la paroi intérieure de la coque et orientes en direction d'une traverse de structure rigidement reliée aux extrémités des longerons du cassis. MOTOR VEHICLE BUMPER DEVICE
The invention relates to a bumper device for a motor vehicle constituted by an outer shell which extends transversely and laterally in front of the bodywork and which has parallel horizontal reinforcing strips connected to the inner wall of the shell and oriented towards a cross member rigidly connected to the ends of the longitudinal sides of the blackcurrant.
La publication FR-A-2 632 587 décrit un tel parechocs monobloc en plastique tel que le polypropylène sur lequel les lames portent des moyens de fixation du pare chocs à la structure du véhicule.Publication FR-A-2 632 587 describes such a one-piece plastic bumper such as polypropylene on which the blades carry means for fixing the bumper to the structure of the vehicle.
Lorsque le pare chocs est déformé de façon élastique par une charge extérieure en raison d'un choc contre un autre véhicule, les lames de renforcement sont soumises à une compression. n en résulte que le bord supérieure du pare chocs s'écrase contre la carrosserie. Dans ces conditions le parechocs conserve une efficacité réduite aux chocs occasionnés à faible vitesse, notamment au cours des manoeuvres de parcage du véhicule.When the bumper is resiliently deformed by an external load due to an impact against another vehicle, the reinforcing blades are subjected to compression. As a result, the upper edge of the bumper crashes against the body. Under these conditions, the bumper retains a reduced effectiveness in impacts caused at low speed, in particular during parking maneuvers of the vehicle.
Dans le but de renforcer le parechocs, il est connu de remplir la coque extérieure par une résine de structure cellulaire. Un tel paretchocs connu par la publication FR-A-2 534 847 nécessite une structure à chambres de remplissage.In order to strengthen the bumper, it is known to fill the outer shell with a cell structure resin. Such a paretchock known from the publication FR-A-2 534 847 requires a structure with filling chambers.
L'invention a pour objet un parechocs qui possède des organes de renforcement localisés dans le but de conférer à la carrosserie une protection accrue.The subject of the invention is a bumper which has localized reinforcement members in order to give the bodywork increased protection.
Selon l'invention, les lames sont partiellement encastrées dans la traverse de structure et enveloppent localement un élément de butée absorbeur d'énergie.According to the invention, the blades are partially embedded in the structural cross member and locally envelop an energy absorbing stop element.
D'autres caractéristiques et avantages de l'invention apparattront à la lecture de la description d'un exemple de réalisation du dispositif pao chocs en référence au dessin annexé dans lequel: - la figure 1 est une vue en plan d'une partie du dispositif parechocs conforme à l'invention, - les figures 2, 3 et 4 représentent les coupes transversales du dispositif selon les lignes II - m - IV de la figure 1.Other characteristics and advantages of the invention will appear on reading the description of an exemplary embodiment of the pao shock device with reference to the appended drawing in which: - Figure 1 is a plan view of a part of the device bumpers according to the invention, - Figures 2, 3 and 4 show the cross sections of the device along lines II - m - IV of Figure 1.
Selon la figure 1 le parechocs est constitué par une coque extérieure 1 pouvant être montée aux extrémités avant ou arrière d'une carrosserie de véhicule respecdvement au moyen d'une traverse de structure 3 rigidement reliée aux extrémités des longerons 4 du chassies du véhicule.According to Figure 1 the bumper is formed by an outer shell 1 which can be mounted at the front or rear ends of a vehicle body respecdvement by means of a structural cross member 3 rigidly connected to the ends of the side members 4 of the vehicle casings.
La coque 1 s'étend latéralement le long des ailes avant ou arrière de la carrosserie ainsi que cela est bien connu.The shell 1 extends laterally along the front or rear wings of the body as is well known.
Des lames horizontales parallèles de renforcement 6,7 sont raccordées à la paroi intérieure 8 dc la coque 1 et orientées en direction de la traverse 3.Parallel horizontal reinforcing strips 6,7 are connected to the interior wall 8 of the shell 1 and oriented in the direction of the cross-member 3.
Ainsi que cela est représenté aux figures 2, 3, la traverse 3 possède une section générale en C dont l'ame verticale est tournée vers les lames 6, 7.As shown in FIGS. 2, 3, the cross-member 3 has a general section in C, the vertical core of which is turned towards the blades 6, 7.
Cellesci s'étendent transversalement le long de la paroi 8 tandis que le bord supérieur 10 de la coque 1 repose sur une lame d'appui transversale 11 montée sur une succession de renforts verticaux 12 transversalement espacés entre deux zones de butée 1S, sensiblement situées dans la zone d'assemblage de la traverse 3 avec les extrémités des longerons 4. These extend transversely along the wall 8 while the upper edge 10 of the shell 1 rests on a transverse support blade 11 mounted on a succession of vertical reinforcements 12 transversely spaced between two abutment zones 1S, substantially located in the assembly area of the cross member 3 with the ends of the side members 4.
Dans le but de renforcer le pare chocs sous l'action de pousses longitudinales, les lames 6, 7 sont partiellement et localement encastrées dans la traverse 3 ainsi que cela est montré à la figure 2 et enveloppent deux éléments de butée 20 absorbeurs d'énergie respectivement localisés dans les zones 15.In order to reinforce the bumper under the action of longitudinal shoots, the blades 6, 7 are partially and locally embedded in the cross member 3 as shown in FIG. 2 and envelop two stop elements 20 energy absorbers respectively located in zones 15.
Les éléments de butée 20 sont localisés entre des sections de la coque 1 dans lesquelles son bord extérieur supérieur 10 est encastré sous le bord du décrochement 21 sensiblement horizontal de l'aile latérale de la carrosserie comme montré à la figure 4. La paroi intérieure 8 reçoit conformément à l'invention une poussée verticale communiquée par un organe presseur 22.The abutment elements 20 are located between sections of the shell 1 in which its upper outer edge 10 is embedded under the edge of the substantially horizontal recess 21 of the lateral wing of the bodywork as shown in FIG. 4. The inner wall 8 according to the invention receives a vertical thrust communicated by a pressing member 22.
Celuisi est constitué par une patte élastique rivée sur le panneau 23 de la carrosserie constitutif de l'aile avant ou arrière rigidifiée par une tôle de doublage 24. This is constituted by an elastic tab riveted on the panel 23 of the bodywork constituting the front or rear wing stiffened by a lining sheet 24.
