Abstract
An energy absorber strut includes a pair of elongated drive nuts threaded internally to mate with a drive screw having high lead threads on opposite ends so that outward movement of the nuts on the screw rotates the screw in one direction and inward movement rotates the screw in the opposite direction. A mandrel mounted to rotate with the screw is restrained from rotation by a capstan spring which surrounds and grips it. Prestressed torsion springs connected to the ends of the capstan spring permit it to unwind slightly and drag with respect to the mandrel when the torsion springs are subjected to a predetermined torque.
