BRAKE ASSEMBLY FOR A SELF-RETRACTING LIFELINE ASSEMBLY

摘要

A braking system for a self - retracting lifeline assembly (100) is provided. The braking system includes a housing (102), a ratchet cam (110) and a clutch assembly (115). The housing includes sidewalls (112) that form, at least in part, a cavity (120). The sidewalls of the housing terminate in a connecting surface (112a) that extends around the cavity. The sidewalls have a plurality of notches (130) spaced along interior surfaces of the sidewalls. Each notch extends from the connecting surface a select distance in the interior surfaces (112b) of the sidewalls of the housing. The ratchet cam includes an inner edge (110a) that defines a central cam opening (110f). The inner edge of the ratchet cam has a plurality of inward extending teeth (110b). The ratchet cam further has an outer edge (110c). The outer edge has a plurality of outward extending fingers (110d). Each finger terminates in a finger tip (110e). Each finger tip is received in an associated notch in the interior surface of the housing.
