The present invention has an object to permit operation of the second pretensioner operating upon determination of a collision, irrespective of operation of the first pretensioner operating upon determination of the possibility of collision. When a vehicle body deceleration is determined not to exceed a set deceleration, possibility of collision with an obstacle is determined on the basis of a relative distance from the obstacle, a relative speed, and a vehicle speed of the subject vehicle. When the possibility of a collision is determined, a motor associated with a retractor is rotated and the webbing is retracted with a large torque until the webbing has the second set belt tension. When the vehicle deceleration is determined to be over a set deceleration, a buckle pretensioner is operated. The buckle is very strongly pulled, and the webbing is set at a third belt tension. The passenger is thus restrained by a large restraining force. At this point, the buckle pretensioner is preferentially operated irrespective of operation of the motor.
