POLYMERIC SHOCK ABSORBING ELEMENT FOR A VEHICLE AND LONGITUDINAL SIDE MEMBER

摘要

Polymeric shock absorbing element for a vehicle including a substantially honeycomb structure having a plurality of channels which has a lateral external surface extending from a first open frontal end to a second open rear end, the shock absorbing element insertable and securable within an internal lateral cavity of a chassis of said vehicle, the internal lateral cavity being defined by at least two metallic plates. The lateral external surface includes at least one substantially planar face positioned on one side of the polymeric shock absorbing element and the additionally includes at least one metallic fixing element having a central portion which in turn includes a first central wall which is made integral with a corresponding substantially planar face of the lateral external surface, the at least one metallic fixing element additionally includes a plurality of side stiffeners which are weldable or made integral with the two metallic sheets.
