ABSTRACT:
Vehicle seat belt apparatus includes an electric-type pretensioner that includes a motor for rotationally driving a belt reel to take up a belt. The apparatus also includes: a take-up position detection section for detecting a take-up position of the reel; a traveling condition determination section for determining that a traveling condition of the vehicle has varied to a predetermined condition; and a control section for controlling power supply to the motor, on the basis of a signal output from the determination section, to thereby control a driving amount of the motor but also for controlling the reel, in accordance with a detection signal output by the take-up position detection section, so that the reel is kept at a predetermined take-up position, to thereby hold a vehicle occupant in a seat with the belt.
