To provide a vehicular side airbag device comprising a side airbag that is expanded and inflated at a center side of a vehicle away from a door to protect an occupant, which has an outer shape-configuration that can efficiently and effectively constrain the occupant, from the head to the waist of the occupant.SOLUTION: The vehicular side airbag device has a side airbag 2 that is supplied with inflator gas to be expanded and inflated through a side of a seat toward a front side of a vehicle, at a center side of the vehicle away from a door. The side airbag includes an upper region P in which a position of inflation completion is to be in the vicinity of the head of an occupant and a lower region Q in which a position of inflation completion is to be in the vicinity of the chest of the occupant and be below the chest. In the side airbag, maximum horizontal cross sectional areas Qs and Qs' of the lower region cut by a horizontal surface H orthogonal to a vertical line G at the time of inflation completion are smaller than maximum horizontal cross sectional areas Ps of the upper region cut by the horizontal surface.SELECTED DRAWING: Figure 2

    【課題】ドアから遠隔な車両中央側で展開膨張されて乗員を保護するサイドエアバッグを対象として、乗員の頭部から腰部にわたって、効率的かつ効果的に乗員を拘束することが可能な外形形態を有するサイドエアバッグを備えた車両用サイドエアバッグ装置を提供する。【解決手段】インフレータガスが供給され、ドアから遠隔な車両中央側で、シートの側方を通って車両前方へ向かって展開膨張されるサイドエアバッグ2を有する車両用サイドエアバッグ装置であって、サイドエアバッグは、膨張完了位置が乗員の頭部近傍に予定された上部領域Pと、膨張完了位置が乗員の胸部近傍及び当該胸部から下方に予定された下部領域Qとを含み、サイドエアバッグは、膨張完了時の鉛直線Gと直交する水平面Hで切断した下部領域の最大水平断面積Qs,Qs’の大きさが、当該水平面で切断した上部領域の最大水平断面積Psの大きさよりも小さい。【選択図】図2
