Automatic seat belt locking system for vehicle
 There is provided an automatic seat belt locking system for a vehicle, e.g., an automobile whereby while in the normal condition the vehicle occupants are not restrained by their seat belts, the seat belts are automatically locked to secure and protect the occupants in the case of an emergency such as a collision. The system comprises a pair of acceleration/deceleration detectors which are composed for example of two different types of mercury switches and which are also adapted to respectively generate a first and second output signal when the acceleration or deceleration of the vehicle exceeds a first and second predetermined value, and absorbing means whereby transient accelerations greater than the first predetermined value and caused by disturbances are absorbed to render both of the detectors inoperative while the vehicle is running on an incomplete, rough road surface.
