Abstract
A emergency locking retractor includes a reel equipped with cogs; lock means capable of assuming any one of a reel-locking position, an intermediate position where the lock means is in engagement with one of the cogs of the reel but still allows the reel to rotate slightly, and a reel non-locking position; first biasing means holding the lock means normally at the non-locking position; an inertia member; second biasing means for normally allowing the inertia member to rotate together with the reel; transmission means for transmitting rotation of the reel to the lock means when the inertia member moves relative to the reel, whereby the lock means is caused to return from the non-locking position to the intermediate position against the first biasing means; and means for permitting the release of connection between the inertia member and transmission means by the second biasing means when the lock means is forced to move to the locking position by a further slight rotation of the reel subsequent to a displacement of the lock means to the intermediate position by the transmission means.
