ABSTRACT:
An energy absorber comprises a housing (1), a store (15) of plastically deformable material (8) mounted in the housing and having an endstop (27), an attachment (3) for attaching the energy absorber to a structure, another attachment (10) for attaching the plastically deformable material (8) to a structure, and the housing mounting a pair of spaced pins (5, 6) around which the deformable material (8) from a coil is plastically deformed in different directions in a sequential manner to absorb energy. The endstop (27) limits the plastic deformation.
