Abstract
An airbag system includes an airbag having an occupant side surface facing an occupant and an opposite side surface facing a vehicle body in an inflated state, and having an interior partitioned into a plurality of chambers including at least an upper chamber and a lower chamber; a gas generator disposed in the airbag; and a gas distributor having a discharge port for discharging gas from the gas generator into at least the upper chamber and the lower chamber. The gas distributor has a gas-distributing connecting line extending substantially linearly for connecting the occupant side surface and the opposite side surface of the airbag.
