Abstract

An energy absorbing assembly can comprise: a support structure having a first wall and an outer wall that extend in an x direction from a first end to a second end; an energy absorber that extends across the first wall of the support structure, the energy absorber comprising a plurality of crushable members are configured to crush and absorb energy upon impact, a first crash can; and a second crash can, wherein the first and second crash cans extend from the first and second ends of the support structure. The energy absorbing assembly is an in situ formed single element. A method of making an energy absorbing assembly can comprise: introducing molten thermoplastic material to a mold to in situ form the energy absorbing assembly and removing the energy absorbing assembly from the mold by moving the mold in a y direction.
