ENERGY ABSORBER AND METHOD OF ABSORBING ENERGY

摘要

An energy absorber has first and second anchorages (18) and is adapted to absorb energy when and only when an applied load along a line of action extending generally through said anchorages exceeds a predetermined limit. The energy absorber comprises at least one leaf (10) extending between the anchorages, the or each leaf having corrugations (16) transverse to said line of action and being arranged to undergo permanent deformation through straightening or deepening of said corrugations as the applied load exceeds the predetermined limit. A structure including the energy absorber, a vehicle including said structure, a method of manufacturing an energy absorber and a method of absorbing energy are also disclosed.
