ABSTRACT:
High velocity impact landing forces are attenuated in apparatus (10) utilizing an energy absorbing tube (12) of composite fibrous material, that is, a fiber reinforced plastic. The energy absorbing tube (12) is disposed in force transmitting relation between an anvil (14) disposed at one end and structure (16) for applying a force to the opposite end of the tube (12) to provide force attenuating apparatus. The tube (12) is progressively crushed onto the anvil (14) by the force applying structure (16) to dissipate energy. The force attenuating apparatus (10) is used in an energy absorbing seat (20) to provide occupant protection against high impact forces. Other uses of the force attenuating apparatus (10) is in a landing gear mechanism (76) and a vehicle bumper system (89).
