Abstract
A retractor reel for vehicle safety belts of the type in which the belt is automatically wound onto a rotatably supported shaft, when the belt is not used, comprises a first locking means and a second locking means, one of which being attached to the support and the other being attached to the rotatable shaft. One of the locking means is movable and arranged to be moved between an idle position, in which it does not engage with the other locking means, and an operative position, in which it engages with the other locking means for locking the shaft. The two locking means are positioned at one end of the rotatable shaft, and two further locking means are positioned at the opposite end of the shaft, where the shaft is supported by a bearing which is arranged to yield, when the shaft is heavily loaded. When the bearing yields, the two further locking means will engage with each other to lock the end of the shaft, so that the shaft will be locked at both ends when heavily loaded. This will increase the strength of the support.
