摘要： A self-retracting lifeline includes a common, central brake hub having teeth on opposing sides and a lifeline assembly on each side of the brake hub. The lifeline assemblies include centrifugal clutch assemblies with pawls. The pawls are configured and arranged to engage the teeth of the brake hub to stop the lifeline assemblies when there is a sudden acceleration or a high rate of speed at which the lifeline assemblies turn to pay-out lifeline which causes the pawls to pivot and engage the teeth. The self-retracting lifeline may be operatively connected to a safety harness with a connector interconnecting the bottom of the self-retracting lifeline and the straps of the safety harness proximate a dorsal pad assembly and straps interconnecting the housing of the self-retracting lifeline and the straps of the safety harness above the dorsal pad assembly. The lifelines of the self-retracting lifeline exit the housing proximate the top.
