Abstract
An energy absorbing assembly for a roadside crash cushion includes a resilient, self-restoring tube and a compression element positioned inside the tube to brace the tube against compression along a compression axis while allowing compression of the tube in other directions. The compression element is mounted to the tube by a hinge having a first portion secured to the tube, a second portion secured to the compression element, and a hinge portion interconnecting the first and second portions. The hinge reduces bending forces on the fasteners that secure the hinge to the tube and to the compression element in an axial impact.
