PROBLEM TO BE SOLVED: To improve initial occupant restraint performance of an inside bag at the time of lateral collision.SOLUTION: In a vehicle seat 10, an inside bag 36 completes inflation and deployment earlier than a side airbag body 34 in a vehicle width direction inner side of the side airbag body 34, and presses an occupant P to the vehicle width direction inner side. Since the inside bag 36 inflates and deploys more on a vehicle upper side from an abdominal part B of the occupant P, the abdominal part B having low load resistance can be prevented from being pressed by the inside bag 36. Further, a reaction force is applied to the inside bag 36 toward the vehicle width direction inner side from a reaction force plate 38 supported by an outer side frame 24. The reaction force plate 38 extends in a vehicle longitudinal direction in a flat cross-sectional view of a seat back 14, and extends more to a vehicle front side from a front edge part 24F of the outer side frame 24 in a vehicle width direction view. Thus, the reaction force can be satisfactorily applied to the inside bag 36 even at a height at which the inside bag 36 is hard to obtain the reaction force from the outer side frame 24.SELECTED DRAWING: Figure 1

    【課題】側面衝突時における内側バッグの乗員初期拘束性能を向上させる。【解決手段】車両用シート10では、内側バッグ36は、サイドエアバッグ本体34の車両幅方向内側において、サイドエアバッグ本体34よりも早期に膨張展開を完了し、乗員Pを車両幅方向内側へ押圧する。この内側バッグ36は、乗員Pの腹部Bよりも車両上方側で膨張展開するので、荷重耐性が低い腹部Bが内側バッグ36によって押圧されることを防止できる。しかも、この内側バッグ36は、外サイドフレーム24に支持された反力板38から車両幅方向内側向きの反力を付与される。この反力板38は、シートバック14の平断面視で車両前後方向に延在しかつ車両幅方向視で外サイドフレーム24の前縁部24Fよりも車両前方側へ延びている。これにより、内側バッグ36が外サイドフレーム24から反力を得られ難い高さにおいても、内側バッグ36に対して良好に反力を付与することができる。【選択図】図1
