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.

Abstract: A locking device for vehicle safety belts of the type in which a band of the belt is automatically wound onto a shaft (14) rotatably mounted between two side walls (12, 13) of a support, when the belt is not used, comprises two notched wheels (22, 23) attached to the shaft, and at least one moveable locking bar (32, 33). The locking bar is adapted to cooperate with the notched wheels (22, 23) for locking the shaft and to be moved between a passive position in which it is positioned outside the rotation paths of the notches, and an active position in which it runs into the rotation paths of the notches, so that the rotation of the notched wheels and thus of the shaft is prevented and further band cannot be withdrawn from the shaft. The notched wheels (22, 23) are positioned adjacent one side wall (13) on either side of the wall and the locking bar (32, 33) is adapted to pass through an aperture in the wall.

Abstract: A retractor reel for a vehicle safety belt comprising a shaft rotatably mounted on a support adapted automatically to wind a safety belt when the belt is not in use and incorporating means for locking the shaft to prevent the belt being withdrawn from the retractor reel under certain conditions, said locking means comprising stop abutment means on said support and at least one locking pin which extends through an aperture in the shaft, substantially diametrically across the shaft, substantially perpendicularly to the longitudinal axis of the shaft, the locking pin being axially movable between a retracted position and an extended locking position, the locking pin, when in the locking position, having an engagement end extending out of the shaft on one side thereof to cooperate with a stop abutment means provided on the support to prevent rotation of the shaft, the opposite end of the locking pin engaging the shaft on the other side of the axis of the shaft that is remote from the engagement end of the locking
