ABSTRACT:
A self-retracting lanyard having a housing; a rotatable drum in that housing; a line for winding about that drum; and an improved braking mechanism for preventing the drum in that housing from ratcheting due to line rebounding after a fall arrest event. The braking mechanism has a plurality of pawl lockout elements for flexibly engaging with a stationary component of the lanyard to keep at least one pawl in a locked position during reverse rotation of the drum thereby preventing ratcheting from occurring.
