Abstract:
1. A side airbag device for a vehicle, comprising: a side airbag having a high pressure chamber that becomes a high pressure side at a time of inflation and deployment, and a low pressure chamber that becomes a lower pressure than the high pressure chamber, the high pressure chamber and the low pressure chamber each inflating and deploying at a time of a side collision; a partitioning wall that is formed by an end portion of an outer base cloth that is positioned at a seat transverse direction outer side of a vehicle seat, and an end portion of an inner base cloth that is positioned at a seat transverse direction inner side, the end portion of the outer base cloth and the end portion of the inner base cloth being part of either a high pressure chamber base cloth or a low pressure chamber base cloth, the end portion of the outer base cloth and the end portion of the inner base cloth being sewn together, the partitioning wall dividing the high pressure chamber and the low pressure chamber; an inflator that, at a time of a side collision, jets-out gas for inflation from a gas jetting-out portion, and supplies gas to an interior of the side airbag; and a check valve that is provided integrally with the partitioning wall, and that is formed by at least one of the outer base cloth or the inner base cloth extending toward a high pressure chamber side, at a seat rear side within the side airbag, and that permits flowing of gas, jetted-out from the gas jetting-out portion of the inflator, from the low pressure chamber to the high pressure chamber, and that regulates flowing of gas in an opposite direction.
