Abstract
A control module for seat belt retractor capable of controlling a winding torque of a seat belt within a predetermined range, and such a seat belt retractor are provided. The seat belt retractor includes a spoolaround which a seat belt for vehicle is wound, a motorthat causes the spoolto rotate, and a motor power transmission mechanism unit that couples the motorand the spoolA microcomputeruses a preset control parameter value to control a motor current that flows through the motorThe microcomputerchanges, based on the motor current and an output torque value of the spool, the control parameter value. The control parameter value is an apparent torque constant for each seat belt retractor product.
