ABSTRACT:
A shock mitigating tether system includes a helical coil spring mounted within a tubular housing between opposing retention plates. A first cable is folded in half and journaled through the longitudinal axis of the spring such that a loop end projects from a first end of the spring and a pair of opposing ends of the cable are mounted to the tension plate on the second end of the spring. A second cable is also journaled longitudinally through the spring with a second cable loop projecting outwardly through an opening in the second plate and the second cable free ends mounted to the first plate, such that the cable loops project in opposing directions along the longitudinal axis of the coil spring. A pair of pins are mounted through diametric apertures in the ends of the housing outwardly of the plates, to retain the spring and plates within the housing.
