Claims

[Scope of utility model registration request]

In a safety belt winding device in which a safety belt, one end of which is fixed to a belt winding shaft interposed between both side plates of a U-shaped frame, can be pulled out and retracted, the safety belt is fixed to the tip of the shaft. a shaft driving gear, a motor having a driving gear fixed to a rotating shaft, a decelerating gear mechanism that decelerates the rotation of the driving gear and transmits the rotation to the shaft driving gear, and a decelerating gear mechanism that reduces the movement of the decelerating gear mechanism. A lock lever that moves between a locking position and an unlocking position, a solenoid that drives the lock lever, and a solenoid that is rotatably attached to one end of the U-shaped frame, with a free end attached to the safety belt. a tension detection lever that detects the tension of the safety belt by contacting the tension detection lever and rotates according to the degree of the detected tension; 2. a control switch that switches a third contact; a control switch that drives the solenoid to lock rotation of the shaft when the first contact of the control switch is closed; and that drives the motor when the second contact is closed; A control circuit is provided that performs control such as idling and winding up the safety belt by rotating the motor when the third contact is closed, thereby optimizing the tension applied to the safety belt when the safety belt is worn. A safety belt winding device characterized by:
