Safety belt device for seat of vehicle, has withdrawal speed locking part locking belt, and control unit controlling shorting of terminals by short-circuit part on basis of withdrawal speed that is detected by withdrawal speed locking part
Safety belt device for seat of vehicle, has withdrawal speed locking part locking belt, and control unit controlling shorting of terminals by short-circuit part on basis of withdrawal speed that is detected by withdrawal speed locking part
The device has a short-circuit part (5) shorting power supply terminals (23b, 23c) of an engine (23), which rolls up a safety belt (13). An extraction of the belt is prevented by the short-circuit part of the power supply terminals of the engine. A withdrawal speed locking part (26) locks the belt, and a control unit controls shorting of the power supply terminals by the short-circuit part on basis of withdrawal speed that is detected by the withdrawal speed locking part. The short-circuit part is alternatively switched between the shorting and opening of the power supply terminals.
