ABSTRACT:
A preferred embodiment self-retracting lifeline (100) includes a centrifugal clutch assembly (121) having a pawl (128) and a spring (131). The pawl (128) and the spring (131), which do not require any fixed attachment to any other component of the device, are held in place and pivotable within a plate (143). The plate (143) is rotatable within a cavity (120) of a brake hub (118) including teeth (141) extending into the cavity (120). When a centrifugal force is applied, the pawl (128) compresses the spring (131) and moves away from the plate (143) to engage the teeth (141) thereby activating a brake assembly within the self-retracting lifeline (100).
