ABSTRACT:
An air bag for side collision is arranged substantially in the vertical direction between a vehicular inner wall and a passenger in an expanded state of the air bag. A lower side of the air bag is folded to be incorporated into the lower side in the expanded state. The lower side of the air bag in the expanded state is the upstream side of flow of expansion gas. The air bag has a narrowed gas flow port for regulating the flow of the expansion gas between the lower side and the upper side of the air bag in the expanded state so that the lower side can ensure sufficient inner pressure even when the passenger interferes with expansion of the lower side of the air bag during expansion, since the flow of the expansion gas is regulated by the gas communication port provided between the lower side and the upper side of the air bag. As a result, an inflator having small output can be used.
