ABSTRACT:
An improvement in a safety belt reel in which a pawl is moved when a predetermined acceleration is exceeded to lockably engage a toothed wheel. The improvement includes a flexible member which is moved when the predetermined acceleration is exceeded so as initially to engage a tooth on said toothed wheel before said pawl causes locking of the reel. The flexible member is movable relative to the pawl whereby any impact between said member and said tooth is absorbed without causing a reaction on an acceleration responsive actuator such as a ball and saucer, or suspended mass, so that the pawl is subsequently urged into correctly phased engagement with the toothed wheel to lock the reel.
