To improve initial restraint performance of a head.SOLUTION: A head chamber 46A of a vehicle side air bag device 40 comprises: a rear duct part 46A1 which is expanded and developed in a head H side of an occupant P corresponding to a shoulder belt 32A of a seat belt 32; and a front part 46A2 which is expanded and developed through the vehicle upper side of the shoulder belt 32A from the rear duct part 46A1 to the vehicle front side. At least at the initial stage of expansion and development of the front part 46A2, a bottom edge LE of the front part 46A2 is positioned at the vehicle upper side compared with the shoulder belt 32A when being viewed in the vehicle longitudinal direction.SELECTED DRAWING: Figure 2
【課題】頭部の初期拘束性能を向上させる。【解決手段】車両用サイドエアバッグ装置40では、頭部チャンバ46Aは、シートベルト32のショルダベルト32Aに対する乗員Pの頭部H側へ膨張展開する後方ダクト部46A1と、ショルダベルト32Aの車両上方側を通って後方ダクト部46A1から車両前方側へ膨張展開する前部46A2とを有し、少なくとも前部46A2の膨張展開初期において、前部46A2の下端LEが車両前後方向視でショルダベルト32Aよりも車両上方側に位置する。【選択図】図2
