<p><P>PROBLEM TO BE SOLVED: To provide a seat belt retractor capable of efficiently carrying out winding-up of a seat belt. <P>SOLUTION: The seat belt retractor comprises a control unit 123 which stops actuation of a motor when an overload of the motor is detected during winding up the seat belt, and restarts the actuation of the motor after a lapse of a predetermined time period. The control unit 123 comprises a motor actuation timing section 403 which clocks a time period from the start of the actuation to the stop of the actuation (motor actuating time period), a motor actuation counting section 404 which counts the number of times of starting the actuation of the motor (motor actuation number), and a retry determining section 405 which determines whether or not it is required to restart the actuation of the motor which is stopped by detection of the overload according to the motor actuating time period and the motor actuation number. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
