Abstract
A retractor has a reel biased in a belt take-up direction and rotatably supported by a base member, and a belt take-up force locking mechanism capable of assuming a position in which it is interlocked with rotation of the reel and a position in which it is non-interlocked with rotation of the reel. The belt take-up force locking mechanism is adapted, when it assumes the interlocked position, to move from and towards its initial interlocked position in response to rotation of the reel and prevent take-up of the portion of the belt already drawn out. An emergency-locking mechanism provided for sensing at least a draw-out speed change of the belt above a predetermined value and connecting the reel to the base member to prevent rotation of the reel in a belt draw-out direction. The emergency-locking mechanism is adapted, when the belt take-up force locking mechanism is in its initial interlocked position to prevent undesired lock-up of the retractor but to operate properly in an emergency.
