Abstract
An elongated energy-absorbing bumper assembly including energy-absorbing elastomeric or foam material extending between a rear mounting surface and a front impact surface with the material defining a hollow recess extending thereinto from the rear mounting surface and positioned between the ends of the assembly. The elastomeric foam material extends to the rear mounting surface at both ends of the hollow recess to define block-like end portions of the elastomeric material. A structural member extends between the block-like end portions of elastomeric material with the ends of the member embedded in the elastomeric foam material. The elastomeric material is the sole support and means of positioning the member so that the member is allowed unguided movement with the elastomeric material in multiple directions upon impact.
