摘要： An energy absorbing device, suitable for use in the leg structure of aircraft passenger seating for the purpose of attenuating crash forces, having first and second attachment fittings 11, 21 with a tube 10 of fiber reinforced plastics material extending between them. Tube 10 has a crush initiation band 17 at which buckling of the tube commences upon compressive overload. Long, tough fibers are used as the reinforcing material in the tube so that, when compression of the device has concluded, there is a residual tensile capability. Successful operation of the device is facilitated by providing attachment fitting 12 with a slider 15 which helps to maintain the collapsing portion of the tube in axial alignment with the uncollapsed portion. The slider also acts as a tube wall straightener to unbuckle the collapsed fibers when tensile load is applied.
