Abstract

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.
