摘要： A seat belt retractor, which is capable of winding and unwinding a seat belt for occupant restraint by mechanism of an electric motor, removes slack of the seat belt and controls the restraining feeling on a vehicle occupant to be as little as possible. A seat belt retractor of a seat belt apparatus to be installed in a vehicle is adapted to control a motor to perform an action of increasing seat belt tension to wind up a seat belt which is excessively unwound from the spool when a vehicle occupant wears the seat belt and to be driven according to such a setting that, at the initial stage of the action of increasing the seat belt tension, the tension increasing rate until the seat belt tension reaches a target tension is lower than a predetermined rate.

摘要： A seat belt retractor, which is capable of winding and unwinding a seat belt for occupant restraint by an electric motor, warns a vehicle occupant. A seat belt retractor of a seat belt apparatus to be installed in a vehicle is structured such that a motor is controlled to repeat an action of increasing and decreasing the tension acting on a seat belt a plurality of times according to a setting that the seat belt tension at the initial stage of each action overshoots a predetermined target tension, for the purpose of warning a vehicle occupant who wears the seat belt.

摘要： A winding control method of a seatbelt retractor for winding a seatbelt with a motor includes detecting a current flowing through the motor, and stopping the motor when the current exceeds a predetermined value. The winding action is not stopped while the motor is accelerated even when the current exceeds the predetermined value.

摘要： A seat belt retractor including an integral electronic control unit (ECU). The ECU is detachably installed between lower edges of respective both side walls of a frame. Further, a motor is detachably fixed to a lower surface of a case of the ECU. Since the ECU is disposed between the frame and the motor, the ECU can be protected from an external force by means of the frame and the motor.

摘要： A seatbelt retractor integrated with an electronic control unit. A motor is disposed above both side walls of a frame and on the same side as a spool with respect to a back board. The motor is detachably fixed to at least one of the back board and the both side walls and of the frame. The ECU is detachably mounted to an upper stay extending upward from the back board of the frame and to be mounted to the vehicle body. In this manner, the motor and the ECU are integrated with a seatbelt retractor. Since the ECU is mounted to the upper stay, the weight of the ECU is dispersed not only to the main body of the seatbelt retractor but also to the upper stay. Thus, the vibration of the seatbelt retractor may be reduced.
