Abstract
A molded energy absorber includes two sections connected by a plurality of hinge elements. One section has a plurality of telescopically crushable tubular cylinders integrally molded thereon. The two sections are folded together and the energy absorber attaches to a structural vehicle pillar on the inside of the vehicle. Upon impact, the tubular cylinders are fractured and crush telescopically, thereby dissipating much of the impact energy.
