ABSTRACT:
To provide a seat belt winding method, a seat belt retractor, and a seat belt apparatus capable of stopping the motor even when the seat belt is being wound and restarting the winding of the seat belt, and capable of reducing excess repetition of stopping and starting of the motor.A seat belt winding method comprises a start signal detecting step (S1) for detecting a buckle release signal, a starting step (S2) for actuating a motor based on a buckle release signal, an overload detecting step (S3) for detecting overload on the motor, a stopping step (S4) for stopping the motor when overload is detected, a waiting step (S5) for stopping the motor for a certain period of time, a storage checking step (S6) for checking the completion of the winding of the seat belt after a lapse of the certain period of time, and a restart determining step (S7) for counting up the number of times the motor is restarted and terminating the winding operation of the seat belt (S8) when the number of times the motor is restarted reaches a predetermined value.
