Abstract

905,836. Energy-absorbing devices. IRVING AIR CHUTE OF GREAT BRITAIN Ltd. June 29, 1960 [Sept. 1, 1959], No. 29826/59. Class 103 (1). In an energy-absorbing device for use when a moving load is suddenly arrested or retarded, e.g. in the case of falling loads being braked by parachutes, the device comprises a housing, a member slidably disposed with respect to the housing, a sheet of material being located in or on the housing which progressively severed or sheared by a divergent head portion on the slidable member when the latter is moved with respect to the housing. In the embodiment disclosed, one end 12 of the energy-absorbing device is coupled by means of straps, cables or the like to the load for which the device is required and the other end is attached to the movement arresting that device, e.g. the lift web of a parachute. The energy-absorbing device includes a housing composed of three plates 1, 2 and 3 secured together in sandwich by means of screws 4; plates 1 and 2 being provided with recesses 7 and 8 on the faces of the housing to accommodate shear strips 9, 10 of suitable metal. When assembled together the plates form a slideaway for a slidable member 11 having a divergent wedge-like head 14 which overlies the planes of the shear strips 9 and 10 so that on outward movement of the slidable member, strips 9 and 10 are progressively stripped to absorb the kinetic energy. The shear strips may be of uniform thickness throughout their length so that the kinetic energy dissipated when the shearing action takes place will be of a uniform nature or, alternatively, the strips may be of tapered section so that the load required to bring about shearing will progressively increase or decrease during outward movement of the slidable member.
