Patent ID: 7664585

Claim:
A vehicle seat belt apparatus comprising: a belt reel having a belt wound thereon; a motor for driving said belt reel to take up the belt; a control device adapted to adjust an amount of electric current supply to said motor to thereby control a belt-taking-up driving force of said motor; a current sensor adapted to detect an electric current supplied to said motor; and a rotation detection section adapted to detect a rotational position of said belt reel, said control device including: a constant current control execution section adapted to execute a constant current control mode so that the amount of electric current supply to said motor takes a target value; and a target current supply value change section adapted to change the target value when a detection signal output by said rotation detection section has satisfied a predetermined condition in the constant current control mode, wherein said target current supply value change section is adapted to change the target value fewer than a predetermined number of times.
