A vehicle bumper system includes a beam and a thermoformed energy absorber positiones on a face of the beam. The thermoformed energy absorber has a plurality of elongated crush boxes thermoformed from a base flange. Crush boxes near a center of the beam are up to about three inches deep, and as a result have side walls that are stretched when thermoformed, while crush boxes near ends of the beam are much shorter and hence not as thin. As a result, the center area has a softer impact intended to reduce pedestrian injury during impact.
La présente invention a trait à un système de pare-chocs de véhicule comportant une poutre et un amortisseur thermoformé positionné sur une face de la poutre. L'amortisseur thermoformé comporte une pluralité de boîtes d'écrasement thermoformées à partir d'une bride de base. Les boîtes d'écrasement à proximité d'un centre de la poutre ont jusqu'à environ trois pouces d profondeur, et par conséquent comportent des parois latérales qui sont allongées lors du thermoformage, tandis que les extrémités proximales de la poutre sont beaucoup plus courtes et donc pas aussi minces. Ainsi, la zone centrale a un impact plus atténué en vue de réduire le dommage corporel du piéton lors d'une collision.
