  • Patent number: 5113981
    Abstract: A safety line shock absorber that is designed to gradually break the fall and stop the user without the shock that occurs when the standard lanyard reaches full extension. The shock absorber incorporates the structure of a bungy cord in combination with an elongated strip of flat webbing that is folded longitudinally upon itself a plurality of times in an accordian type manner to form a plurality of lapped portions. A plurality of transverse rows of stitching across the respective lapped portions will tear apart and allow the webbing to be stretched out to its unfolded length when excessive force is applied to the longitudinal axis of the safety line shock absorber when a workman hooked up to the shock absorber unexpectedly takes a fall.
