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. A pair of pins ( 7, 33 ) or a guide element ( 51 ) and a pin ( 33 ) are contacted by the endstop ( 27 ) to limit the plastic deformation.
