ABSTRACT:
A visually inspectable shock absorbing safety lanyard to reduce the shock of gravity when a person wearing a safety support system falls from an elevated position. The lanyard comprises a length of material having a first end adapted to be connected to the person, e.g., via a safety belt or harness, and a second end adapted to be connected to a fall prevention device, e.g. a rope grab, and a shock absorbing mechanism located therebetween. The shock absorbing mechanism is disposed within an inner cover to hold the mechanism in place, to keep it clean and to provide a visual indicator that the mechanism may have been tampered with or previously actuated. A readily openable second cover formed of a flexible material and including a releasably securable opening is disposed about the inner cover and is arranged when opened to provide visual access to the inner cover. In the preferred embodiment, the inner cover enclosing the shock is transparent so that the person using the lanyard also can visually inspect the shock absorber mechanism within the inner cover.
