Abstract:
An energy absorption device comprising:a first plastically deformable member having a traveling bight; a second plastically deformable member having a traveling bight; a pusher attached to a first body proximate a first part of said first member; a catch allowing said second member to move a limited distance with respect to the pusher, said distance having a limit beyond which a first part of said second member is effectively fixed to said pusher; an anvil arrangement fixed to a second body, said anvil arrangement being positioned proximate said traveling bights, said traveling bights having a shape corresponding with an anvil surface of said anvil arrangement; said anvil arrangement arranged to force said traveling bight of said first member to travel along a length of said first member upon initial relative movement of said first and second bodies, and cause, upon continued relative movement of said first and second bodies, said traveling bight of said second member to travel along a length of said second member upon said catch reaching said limit, wherein as said traveling bights travel down respective ones of said first and second members, energy is absorbed and dissipated.
