ABSTRACT:
An airbag is inflated by gas for deployment to the front of and for restraining an occupant. A tether allows an inner capacity of the airbag to be equal to or smaller than a predetermined value by restricting a distance between a proximal end of the airbag and a surface of the airbag at deployment. A control unit acquires information relating to at least one of an occupant seat position, an occupant position to an instrument panel, an occupant physique, an occupant weight, and a magnitude of a collision impact. A release unit controls capacity and configuration of the airbag by releasing an end of the tether at a side of the proximal end according to the information acquired by the control unit. A vent discharges the gas before activation of the release unit and is closed on activation of the release unit.
