Abstract
A vehicle bumper system includes a bumper beam and a polymeric energy absorber positioned on a front of the bumper beam. The energy absorber has multiple box-shaped sections and also has interconnecting sections positioned along the length that interconnect adjacent ones of the box-shaped sections. The box-shaped sections of the energy absorber, when cross-sectioned by a transverse plane, include top and bottom U-shaped sections formed by top parallel legs and a top vertical leg and by bottom parallel legs and a bottom vertical leg, respectively. End walls close ends of the box-shaped sections and stabilize the top and bottom U-shaped sections. The interconnecting sections include a tying wall that connects the end walls together. By this arrangement, the box-shaped sections provide a stable and reliable energy absorbing mechanism.
