An air bag apparatus comprises a driver seat air bag unit, a passenger seat air bag unit, a driver position detector, a front passenger position detector, and a control unit. The driver seat air bag unit is disposed ahead of a driver seat and has a driver seat air bag unfolded in a two-stage manner. The passenger seat air bag unit is disposed ahead of a front passenger seat and has a passenger seat air bag unfolded in a two-stage manner. The control unit controls second unfolding initiations of the air bags respectively according to the sitting positions. Accordingly, the second stage unfolding of the air bags are initiated at optimal times in accordance with the sitting positions of the driver and the front passenger. As a result, secure restraint of the driver and the front passenger effected by the air bags and reduction in pressure acting on the driver and the front passenger from the air bags are achieved simultaneously on both driver seat and front passenger seat.
