Abstract
A highway crash cushion provides a system response profile that reduces the stopping distance of an impact event. This crash cushion includes a frame that forms at least two bays arranged one behind another in an anticipated impact direction. The frame includes at least three transverse frames and side frames extending between adjacent transverse frames. Each of the side frames is outwardly bowed and includes first and second side frame elements coupled to the respective transverse frames, and a hinge coupled between the first and second side frame elements. At least one energy absorbing element is disposed in one of the bays, and at least first and second restraints are coupled to the side frames to resist movement of the hinges at an early stage in an impact event.
