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 ). |
