PCT No. PCT/SE84/00387 Sec. 371 Date Aug. 20, 1985 Sec. 102(e) Date Aug. 20, 1985 PCT Filed Nov. 14, 1984 PCT Pub. No. WO85/02152 PCT Pub. Date May 23, 1985.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the notches, so that the rotation of the notched wheels and thus of the shaft is prevented and further band cannot be withdrawn from the shaft.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. This will give a solution to the problem of providing a support with a locking device for safety belts having a small size and a low weight, but nevertheless achieving a good distribution and carrying of the forces. A particular embodiment uses two locking bars (32, 33) positioned diametrically in relation to the shaft, so that the force to be carried is distributed over four engagement points. |
