Abstract
An energy dissipation assembly is provided for dissipating energy between a vehicle component and a vehicle sheet metal member. The assembly includes a collapsible crash box forming a central aperture therethrough for receiving the vehicle component. The collapsible crash box includes a plurality of collapsible levels oriented concentrically with respect to the central aperture. A sufficient impact against the component causes collapse of the plurality of levels between the component and the sheet metal member, thereby dissipating energy of the impact.
