To obtain a vehicular side airbag device capable of improving the initial restraint performance for a head portion.SOLUTION: A vehicular side airbag device 40 is equipped with an inflator 44, a side airbag 46, and a duct 48, and is mounted on a side portion 16A on the outer side in a vehicle width direction in a seat back 16 of a vehicular seat 12 where an occupant is restrained with a three-point type seat belt 32. The side airbag 46 is supplied with gas from an inflator 44 upon a side collision. Therefore, a waist portion chamber 46D is expanded and deployed from a lower portion of the side part 16A to a side part of a waist portion W, and a head portion chamber 46A is expanded and deployed from an upper surface 16A1 side of the side portion 16A to a side part of a head portion H of the occupant P. A duct extending in a vertical direction of the side airbag 46 in the side airbag 46 leads the gas from the inflator 44 into the waist portion chamber 46D and the head portion chamber 46A.SELECTED DRAWING: Figure 1
【課題】頭部の初期拘束性能を向上可能な車両用サイドエアバッグ装置を得る。【解決手段】車両用サイドエアバッグ装置40は、インフレータ44とサイドエアバッグ46とダクト48とを備えており、3点式のシートベルト32を用いて乗員が拘束される車両用シート12のシートバック16における車両幅方向外側の側部16Aに搭載される。サイドエアバッグ46は、車両の側面衝突時にインフレータ44からガスの供給を受ける。これにより、側部16Aの下部から乗員Pの腰部Wの側方へ腰部チャンバ46Dが膨張展開すると共に、側部16Aの上面16A1側から乗員Pの頭部Hの側方へ頭部チャンバ46Aが膨張展開する。このサイドエアバッグ46内でサイドエアバッグ46の上下方向に延在するダクトは、インフレータ44からのガスを腰部チャンバ46D内及び頭部チャンバ46A内へ導く。【選択図】図1
