FAILSAFE RETRACTABLE LANYARD MECHANISM

摘要

A failsafe mechanism for a lanyard comprising a backing plate, a pawl rotatably mounted on the backing plate and having an engagement portion and a cam portion, and a sperrad mounted on the backing plate in proximity to the pawl. The sperrad has engagement and cam portions and rotates relative to the pawl to define an engagement zone where the pawl and sperrad engage. The sperrad and pawl engagement portions engage when the pawl engagement portion is within the engagement zone and the sperrad engagement portion rotates into engagement. The pawl is configured to rotate only between a first arc in which the engagement portion remains at least partially within the engagement zone and a second arc in which the pawl halts the sperrad rotation should the pawl be held within the second arc.
