Abstract
A crash structure is provided that is integrated within a vehicle side rail, the crash structure providing relatively level loading during a collision. The structure includes an actuator member coupled to the bumper, the actuator member passing into, and slidably disposed within, a hollow housing of the crash structure. The hollow housing contains a plurality of deformable members that at least partially surround a first portion of the actuator member. A second portion of the actuator member, which is between the bumper and the first portion of the actuator member, has a larger diameter than that of the first portion of the actuator member and is configured to deform the deformable members during a collision.
