Abstract
A shock absorber as designed for use in fall protection systems and may be incorporated integrally with either a belt or lanyard or may be used as a separate component in conjunction with conventional belts and lanyards. A shock absorbing mechanism of the invention utilizes a piercing member having smooth edges which pierce a piece of webbing material. When force is applied to opposite ends of the shock absorber, the piercing member stretches and breaks latitudinal fibers of the webbing material. This allows near complete retention of the strength of the longitudinal fibers as those fibers are not damaged during the absorbing operation.
