ABSTRACT:
A seat belt locking device used with a seat belt arrangement for an automobile vehicle. The locking device locks the seat belt for protecting the driver or passenger from danger when the vehicle is suddenly decelerated in an emergency case such as a collision. The seat belt locking device of the present invention comprises a slidable but unrotatable wedge-shaped seat belt locking member having a pair of roller supporting portions between which a roller is mounted, and a pair of fixed roller shafts the cross section of which is the segment of a circle. The seat belt is so arranged as to pass around the roller of the locking member and the two roller shafts, so that the belt can be firmly caught between the two flat portions of the wedge-shaped seat belt locking member and the respective flat portions of the roller shafts, when the vehicle is suddenly decelerated. The seat belt locking device thus improved can prevent the seat belt from being damaged, even if a strong belt locking force is often exerted, while incorporating a minimum number of necessary parts, without increasing the cost of the device.
