<p>An impact absorbing device for a vehicle (C, Figure 8) includes first and second end connectors 50, 70, the first end connector 50 fixed to a chassis (C1, Figure 8), and at least two energy absorbing members 60A, 60B. Ends of energy absorbing members 60A, 60B are connected to each other and to the end connectors. Each energy absorbing member 60A, 60B comprises a plurality of annularly arranged elongate strips 61 of deformable metal, each bulging arcuately outward relative to a longitudinal axis X of the device. Energy absorbing members 60A, 60B have different fracture toughnesses, for example by being of different lengths, thicknesses or materials, and energy absorbing member 60A with the larger fracture toughness is located closer to the chassis, which may prevent direct transmission of impact energy to the chassis. End connectors 50, 70 may each have an area exceeding 30 square centimetres.</p> |
