To provide a vehicular side airbag apparatus capable of enhancing an initial constraint performance for a head.SOLUTION: A vehicular side airbag apparatus 40 is loaded on, outwardly in the vehicle widthwise direction, a side portion 16A of a seat back 16 of a vehicular seat 12 on which an occupant P is constrained by a three-point seatbelt. According to this apparatus 40, a gas from an insulator 44 is introduced in the upper part and the lower part in a side airbag 46 by a duct 48. A head chamber 46A to protect a head H of the occupant P is provided on the upper part of the side airbag 46. An upper-side ejection port 50 that is opened at the side where the head H of the occupant P is located and within a rear part 46A1 of the head chamber 46A relative to a shoulder belt 32A when the side airbag 46 is expanded and spread is formed at the upper end of the duct 48. The head chamber 46A in an expanded and spread state includes a front upper part 46A2 that extends from the rear part 46A1 to the front side of the vehicle, and a front lower part 46A3 that extends from the front upper part 46A2 to the lower side of the vehicle.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、3点式のシートベルトを用いて乗員P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。この装置40では、インシュレータ44からのガスがダクト48によりサイドエアバッグ46内の上部及び下部へ導かれる。サイドエアバッグ46の上部には、乗員Pの頭部Hを保護する頭部チャンバ46Aが設けられている。ダクト48の上端部には、サイドエアバッグ46の膨張展開時にショルダベルト32Aに対する乗員Pの頭部H側かつ頭部チャンバ46Aの後部46A1内で開口する上側噴出口50が形成されている。膨張展開状態の頭部チャンバ46Aは、後部46A1から車両前方へ延びる前上部46A2と、当該前上部46A2から車両下方へ延びる前下部46A3とを有する。【選択図】図1
