Abstract

A self-retracting safety line device (10) comprising a casing (12), a cable (18) retractably dispensable from the casing (12) and mounted on a spool (14) in the casing (12), capable of movement in two directions, a spool spring to bias the spool (14) in one direction; a locking mechanism (24) to selectively lock the safety line device (10), two locking rings (30, 32) with serrations facing in opposite directions and two sets of inertia pins (40, 42) mounted to an inertia disc (38) fixed relative to the spool (14) and adjacent the locking rings (30, 32), where high accelerating rotation of the spool (14) in the first direction causes braking of the cable (18) in the first direction, and high accelerating rotation of the spool (14) in the second direction causes the cable (18) to brake in the second direction.
