To provide a vehicular side airbag that can improve initial restraining performance at the time of side collision.SOLUTION: A vehicular side airbag 10 comprises a bag main body 12 stored inside a vehicular seat 14. The bag main body 12 receives supply of gas from an inflator 42 to be inflated and expanded when a side collision is predicted or detected, so that an upper chamber 12A covers a side of a head H of an occupant P and a lower chamber 12B covers a side of a portion lower than the head of the occupant. Further, the bag main body 12 is formed by sewing a front base cloth 50 positioned at a front side of the seat and a rear base cloth 52 positioned at a rear side of the seat, at a center part in a longitudinal direction of a vehicle, of the bag main body 12, in an inflated and expanded state when viewed from a width direction of the seat. The front base cloth 50 and the rear base cloth 52 are formed in a shape in which the upper chamber 12A is positioned on an inner side, in the width direction of the seat, of the lower chamber 12B in the inflated and expanded state.SELECTED DRAWING: Figure 2

    【課題】側面衝突時の初期拘束性能を向上することができる車両用サイドエアバッグを得る。【解決手段】車両用サイドエアバッグ10は、車両用シート14の内部に収納されたバッグ本体12を有し、バッグ本体12は、側面衝突の予知時又は検知時にインフレータ42からガスの供給を受けて膨張展開されて上部チャンバ12Aが乗員の頭部の側方を覆い、下部チャンバ12Bが乗員Pの頭部Hよりも下側の側方を覆う。また、バッグ本体12は、膨張展開状態でシート前方に位置する前側基布50とシート後方に位置する後側基布52とをシート幅方向から見てバッグ本体12の車両前後方向中央部で縫製することにより形成されており、前側基布50及び後側基布52は、膨張展開状態で下部チャンバ12Bよりも上部チャンバ12Aの方がシート幅方向内側に位置する形状に形成されている。【選択図】図2
