Abstract
A retractable lanyard mechanism that includes a housing, a frame and a drum that is rotatably supported from the frame mounted within the housing. The drum includes a pair of spaced apart disks, the spaced apart disks being attached to opposite ends of a spool, each spaced apart disk having a perimeter including at least one sperrad. A locking bar that is pivotally mounted from the frame, the locking bar extending from the frame at a location next the perimeter of each of the spaced apart disks and is movable from an up position wherein the locking bar does not engage the sperrad on each of the spaced apart disks, and a down position wherein the locking bar engages the sperrad on each of the disks, the locking bar mechanism being movable from the up position to the down position by a momentum pawl mechanism that is mounted from the frame, so that rotation of both of the spaced apart disks is stopped by moving the locking bar to the down position in response to a level of momentum achieved by the momentum pawl mechanism.
