Abstract
Abstract An automatic retractor of the self-locking type includes a pawl movable into and out of engagement with ratchet shoulders on the end plate of the reel to selectively lock and unlock the reel against movement in an extending direction. A slide is engageable by the pawl each time that the pawl is engaged with the ratchet shoulders to control the rotation of a lobed cam wheel. The cam wheel is engageable with successive lobes of a locking member to move the locking member from either clamped or unclamped position toward the other position. An overcenter spring controls the final movement of the clamping member from a point intermediate either position to the other.
