Abstract
Several embodiments (10, 30, 80) of an energy absorption system are designed for permitting progressive collapse of the system by absorbing energy within the system. In one embodiment, a system (10) comprises conical bodies (12) separated by cables (20), which system progressively collapses through plastic deformation of compression members (16) cooperating with each cable (20). In another embodiment, a system (30) incorporates plastically collapsible compression members (44, 46, 48) which collapse progressively to permit the bodies (32) to move together. In another embodiment, a system (80) is provided where the progressive collapse is permitted by frictional sliding of a securing device (92) along a track (90) which permits bodies (82) to move together.
