PROBLEM TO BE SOLVED: To provide a seat belt device for controlling a seat belt device for driver and a seat belt device for other occupants in a different condition when a collision is generated. SOLUTION: On the basis of the output from a collision forecasting unit 401 for outputting the collision forecast signal corresponding to the probability of collision, the belt tension 110a of a first seat belt device for constraining a driver in a seat and the belt tension 110b of a second seat belt device for constraining other occupant in a front seat or in rear seats are separately controlled. For example, when the probability of avoiding a collision is generated, the belt tension is controlled to a degree that the driver can drive (S18), or generates the vibration so as to call the driver's attention (520). When the occupants except for the driver is sitting within a range of the expansion of an air bag (S52), the belt tension is controlled so as to forcibly return the passenger to the seat. |
