Abstract
An apparatus for dissipating shock load in a parachute delivery system has at least one strip of material having a first end, a second end opposite the first end, and a predetermined length. The apparatus also has a piercing member having a first portion for piercing through the strip of material and a second portion that defines an opening. The strip of material passes through the opening in the piercing member. The first end of the strip of material is configured to be attached to parachute suspension lines. In a preferred embodiment, the strip of material is a strip of woven webbing. When a predetermined tensile force acts upon the strip of material and the piercing member such that the first end of the strip of woven webbing is pulled in one direction and the piercing member is pulled in an opposite direction, tension is produced which causes the piercing member to stretch and break the lateral fibers of the strip of woven webbing. In one embodiment, the apparatus includes a lanyard that has a first end attached to the piercing member and a second end adapted for attachment to a payload.
