Patent ID: 8465087

Claim:
An energy absorber comprising: a base sheet and a plurality of crush lobes extending from the base sheet, each crush lobe including a side wall oriented to crush and collapse to absorb energy when impacted in a first direction and including an end wall, at least one of the base sheet and the end wall of at least one crush lobe including an integrally-formed, hollow countermeasure of lower standing strength than the crush lobes so that the protruding countermeasure acts to dampen movement that would otherwise cause buzzes, squeaks and/or rattles between the energy absorber and an adjacent structure, wherein the countermeasure has a thinner wall thickness than the end wall and the base sheet, and is formed as an elongated protrusion from the same material as the end wall and base sheet, wherein the end wall includes a support section supporting the countermeasure, and wherein the countermeasure is formed from material taken from the support section and flowed into a shape of the countermeasure while the energy absorber material is being formed.
