Abstract
A retractor reel assembly for vehicle safety belt has a rotatable reel which automatically winds in the safety belt when it is not in use, and has a locking arrangement, which is normally in the locked condition. A sensor senses the acceleration or deceleration of the vehicle and the locking means are adapted to be released in response to the withdrawal or attempted withdrawal of a length of safety belt when the acceleration or deceleration of the vehicle is within a predetermined limit. If the acceleration or deceleration of the vehicle is outside the predetermined limit the reel is retained in the locked condition.
