ADAPTIVE ENERGY ABSORPTION SYSTEM

摘要

An energy absorbing assembly (20) providing variable energy absorption from an energy transmitting component (10) is mounted upon a mounting bracket (16) for mounting the energy absorbing assembly (20) to the energy transmitting component (10). An elongated strap (22) immovably secured at a first end (24) absorbs energy received from the energy transmitting component (10) during a collision. Cooperating anvils (30A,B) are slidably received by the mounting bracket (16) and the elongated strap (22) is interwoven between the anvils (30). The anvils (30A,B) include generally parallel axis (a) along which anvil (30A, 30B) defines stepped diameters (A,B,C,D) and are slidable along the axis (a) in response to a predetermined force to provide variably energy absorption relative to the stepped diameters (A,B,C,D).
