PROBLEM TO BE SOLVED: To provide a vehicle seat having a side airbag device which can move a seated occupant to a vehicle width direction center side at an early stage during side face collision, and in which a side airbag can be easily mounted on a seat back having a narrow gap between an outer side frame and the seated occupant.SOLUTION: In a vehicle seat 10, an inflator 56 is attached to the vehicle width direction center side of an outer side frame 22 arranged in an outer side part 16A of a seat back 16, a rear chamber of a side airbag 70 storing the inflator 56 expands and deploys at an earlier stage and with higher pressure than a front chamber while receiving reaction force from the outer side frame 22 toward the vehicle width direction center side, and presses a seated occupant P to the vehicle width direction center side. The side airbag 70 is stored in the outer side part 16A in a state where a portion striding over the outer side frame 22 from a vehicle front side in a vehicle width direction and including the front chamber is folded on the vehicle width direction outer side of the outer side frame 22.SELECTED DRAWING: Figure 3
【課題】側面衝突時に着座乗員を早期に車両幅方向中央側へ移動させることができると共に、外サイドフレームと着座乗員との間の隙間が狭いシートバックへのサイドエアバッグの搭載が容易になるサイドエアバッグ装置を備えた車両用シートを得る。【解決手段】車両用シート10では、シートバック16の外サイド部16A内に配設された外サイドフレーム22の車両幅方向中央側にインフレータ56が取り付けられており、当該インフレータ56を収容したサイドエアバッグ70の後チャンバが、外サイドフレーム22から車両幅方向中央側向きの反力を受けつつ、前チャンバよりも早期かつ高圧に膨張展開し、着座乗員Pを車両幅方向中央側へ押圧する。このサイドエアバッグ70は、外サイドフレーム22を車両前方側から車両幅方向に跨ぎ且つ前チャンバを含む部位が外サイドフレーム22の車両幅方向外側で折り畳まれた状態で外サイド部16A内に収納される。【選択図】図3
