Abstract
A spring having a helical body with opposed ends and two flexible safety cables each of which is coupled to one of said opposed ends, with the two flexible cables extending in opposite directions pass the center of the helical body, terminating in an attachment thereto. The helical body includes a plurality of coils with one end of each of the cables being coupled to one of the plurality of coils. The attachment includes an elliptically shaped journal through which one of the plurality of coils passes, thereby pivotally attaching the cable thereto. In one embodiment, a threaded boss is disposed at each end of the helical body. The threaded boss has a plurality of recesses, each of which is adapted to receive on of the plurality of coils. In this fashion, the threaded boss threadably engages the helical body.
