  • Shoulder harness reel assembly with automatic reel lock
    Patent number: 4801105
    Abstract: A reel assembly for retracting and locking a shoulder harness. The assembly includes a strap supporting spool affixed to a ratchet wheel. When a strap is rapidly pulled from the reel, an inertia mass turns with respect to the reel. This causes the inertia mass to move forward axially and trip a dog which locks the reel. The reel is provided with a resetting mechanism and may also be moved to a position where it remains locked.
