ABSTRACT:
A main controlling section of a controlling unit (13), when judging a collision risk, drives a motor (12) in a direction of retracting a seat belt (3) and raises tension of the seat belt (3). The main controlling section, when tension of the seat belt (3) reaches a predetermined value, judges that a locking signal is input and has the motor (12) continue retracting driving of the seat belt (3) for a predetermined time and, when a locking signal is not input, decreases a driving power of the motor (12) and lowers tension of the seat belt (3). Even when a collision risk signal is erroneously output from a collision risk judging section (11) and, so long as a locking signal is not output from the locking signal producing section (18), since control is immediately exerted so that tension of the seat belt (3) is lowered, it is possible to avoid an unpleasant feeling to a vehicle occupant (A) caused by comparative long-duration and useless restraining using the seat belt (3).
