<p><P>PROBLEM TO BE SOLVED: To provide a motor retractor control method, a motor retractor and a seat belt device capable of reducing the working sound of a motor when uncoupling a clutch of the motor retractor. <P>SOLUTION: The motor retractor 1 comprises a spool 3 for winding a webbing belt 2 for restraining an occupant, a motor 4 driven based on a predetermined signal, a power transmitting means 5 having a clutch mechanism capable of transmitting the power of the motor 4 to the spool 3, a control device 6 for controlling the drive of the motor 4, various kinds of sensors 7a-7d connected to the control device 6 to transmit the signals to drive the motor 4, and a power source 8 for supplying the current to the motor 4. The control device 6 is programmed so as to change the speed of rotation or the driving time of the motor 4 according to the load on the clutch mechanism when the motor 4 is driven in a reverse direction to release the power transmission of the clutch mechanism. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
