摘要： An impact energy absorbing device includes a pair of tubular members arranged for telescopic movement relative one another upon application of impact force thereto, a third tubular member attached to one of the pair of tubular members by annular elastomeric bushings press-fitted in radial compression between the walls of the respective tubular members, and a rotary motion producing mechanism in connection between the third tubular member and the other of the pair of tubular members to convert axial telescopic movement of the pair of tubular members into rotary movement of the third tubular member causing torsional energy storing as well as energy dissipating wind-up of the elastomeric bushings. Relief of the impact force permits the energy stored in the wound-up elastomeric bushings to restore the tubular members to their pre-impact relative positions in readiness for subsequent impacting.
