ABSTRACT:
Each of air bag devices includes an inflator mounted in a seat back, a first air bag which is connected to the inflator and developed into a space between an occupant and a side door, and a second air bag connected to the first air bag and developed into a space between the occupant and an instrument panel. When the internal pressure in the first air bag exceeds a predetermined value, the internal spaces in the first and second air bags are put into communication with each other through a pressure valve. When a vehicle collides with another vehicle or an obstacle, the first air bag is first inflated and developed by a high pressure gas generated by the inflator. When the first air bag has been developed, the pressure valve V is opened, causing the second air bag to be developed. Thus, not only upon a frontal collision and a side collision of the vehicle, but also upon an oblique collision of the vehicle, it is possible to reliably hold the occupant.
