Abstract

A vehicle bumper arrangement (10) comprises a bumper element (12) and a force absorption device (16) positioned between the bumper element (12) and a structure (14) of the vehicle. The bumper element (12) is movable in the direction of the structure (14) of the vehicle in response to an external force (22, 86) applied thereto. The force absorption device (16) is configurable to provide a differing magnitudes of resistive force to the applied external force (22, 86). In one embodiment the force absorption device (16, 416, 516, 616, 716) is configured so as to be able to provide multiple discrete values of resistive force, one of which values is selected prior to, or shortly after, movement of the bumper element (12) in the direction of the vehicle structure (14). In an alternative embodiment the force absorption device (216', 216'', 216''', 316) is configured so as to be able to provide an infinitely variable range of resistive force magnitudes between defined upper and lower limits, one of which magnitudes is selected prior to, or shortly after, movement of the bumper element (12) in the direction of the vehicle structure (14).
