ABSTRACT:
A safety apparatus to be worn by a person located at an elevated position for releasable securement to a holding device, e.g., a rope grab, etc., to protect the person from falling. The apparatus also enables the person to move about relatively unencumbered when supported by it, while also enabling the person to repel down a safety line located adjacent the holding device. The apparatus comprises a first belt, a second belt, and a pair of extendable connecting straps. The first belt is releasably secured about the waist of the person and includes at least one connector, e.g., a D-ring, for releasable securement to the holding device. The second belt comprises an elongated web-like member having a pair of ends, each of which is fixedly secured to the first belt. The second belt is disposed in a stowed position interposed betweeen the first belt and the lower portion of the back of the person but is arranged to be pulled out and down from the first belt to form a seat for the buttocks of the person. Each of the extendable straps is fixedly secured to the second belt has a free end arranged to be readily connected to a lowering device mounted on the safety line to enable the person to repel down the line once he or she has disconnected the first belt from the holding device.
