Energy absorber

An energy absorber comprising a housing for attachment to a first body, a deformer member mounted to the housing, a strip of plastically deformable material extending in a longitudinal direction between first and second ends, an attachment member provided at or towards, the second end of the strip for attachment to a second body, the strip being arranged with the deformer member such that when a predetermined force is applied to the attachment member the strip is moved relative to the deformer member from a first position, in which a first section of the strip extends from the first end of the strip to the deformer member, to a second position such that as the strip is moved from its first position to its second position at least a part of the first section of the strip is plastically deformed by the deformer member, wherein the strip is arranged such that when it is in its first position, the first section of the strip is substantially flat in the longitudinal direction of the first section of the strip, and,

• wherein the energy absorber comprises a first guide member which is arranged to guide the at least a part of the first section of the strip into contact with the deformer member as the strip moves from its first position to its second position, and
• wherein the energy absorber comprises a second guide member which is arranged to guide the movement of the at least part of the first section of the strip once it has been deformed by the deformer member.
