ABSTRACT:
The present invention is a shock absorber for a safety belt lanyard. It comprises, in essence, a strap-like web of strength sufficient to check a fall, having a short base portion at one end and a free reach constituting the remainder. The end of the base portion connects with the center bar of a three-bar slide and the junction between the base portion and the free reach is a connector loop to connect with a lanyard or safety belt. The free reach, commencing at the loop, has its extended end threaded through the three-bar slide to terminate as a second connector loop opposite the first mentioned connector loop to connect with the safety belt or lanyard. The free reach of the web is folded against the base to provide a compact package which is enclosed in a disruptible cover to complete the unit. In use, the free reach is pulled through the three-bar slide to provide the necessary resistance to decelerate the fall.
