Abstract

Pare-chocs oblong. Ce pare-chocs comprend un amortisseur oblong en élastomère se prolongeant entre la face antérieure de percussion et la face postérieure de support et dont la partie médiane en retrait forme en se rapprochant de la face antérieure précitée une cavité séparant 'une de l'autre les extrémités massives de cet amortisseur, et une armature qui relie l'une à l'autre les extrémités massives de l'amortisseur dans l'élastomère duquel sont noyées et encastrées ses propres extrémités. Cet élastomère constituant l'unique de cette armature et le seul moyen de la tenir en place, elle n'est pas guidée et peut se déplacer en tous sens avec l'élastomère sous l'effet d'un choc. Application notamment aux pare-chocs d'automobiles.Oblong bumper. This bumper comprises an elastomeric elastomer shock absorber extending between the front percussion face and the rear support face and the recessed median part of which forms, on approaching the aforementioned anterior face, a cavity separating the one from the other. massive ends of this damper, and a frame which connects the massive ends of the damper to each other in the elastomer of which are embedded and embedded its own ends. This elastomer constituting the only one of this frame and the only means of holding it in place, it is not guided and can move in all directions with the elastomer under the effect of an impact. Application in particular to automobile bumpers.
