Abstract
An occupant restraint system which, when an occupant on a vehicle seat is a child, can change the operational mode of an airbag device to a suitable mode. When the signal from an occupant estimating unit is not ON, an inflator is not actuated even when the output signal of an emergency detecting device is ON. A weight estimating portion determines whether the value of the load applied to the seat detected by weight sensors exceeds a threshold Y. An occupant condition estimating portion determines that the occupant is a child when the tension switch detects a tension exceeding a predetermined value and then sets the output signal of the occupant estimating unit to be OFF. When the tension switch does not detect a tension exceeding the predetermined value and the weight estimating portion determines that the load detected by the weight sensors does not exceed a threshold, it is determined that the occupant is a child and the output signal of the occupant estimating unit is set to be OFF.
