To provide a vehicular occupant protecting device capable of stably expanding and spreading a head chamber between a shoulder belt and a vehicular seat.SOLUTION: A vehicular occupant protecting device 10 includes: a waist chamber 44B which is stored in a state elongated in the vertical direction and outwardly in the vehicle widthwise direction in a side portion 18A of a seat back 18 and which is to be expanded and spread at the side of the waist of an occupant when a side collision is predicted or detected; a head chamber 44C which is stored in a state elongated inwardly in the seat widthwise direction from the upper end of the waist chamber 44B along the upper end of the seat back 18 and which is to be expanded and spread at the side of the head of the occupant; a lower to-be-fractured portion 60 which is provided outwardly in the vehicle widthwise direction at the side portion 18A of the seat back 18 so as to be elongated in the vertical direction, and which is to be fractured by the expansion pressure of the waist chamber 44B; and an upper to-be-fractured portion 62 which is elongated in the seat widthwise direction at the upper portion of the seat back 18, and which is to be fractured by the expansion pressure of the head chamber 44C.SELECTED DRAWING: Figure 3
【課題】頭部チャンバを安定してショルダベルトと車両用シートとの間に膨張展開することができる車両用乗員保護装置を得る。【解決手段】車両用乗員保護装置10は、シートバック18における車両幅方向外側の側部18Aに上下に延在された状態で収納されると共に、側面衝突の予知時又は検知時に乗員の腰部の側方に膨張展開される腰部チャンバ44Bと、腰部チャンバ44Bの上端部からシートバック18の上端部に沿ってシート幅方向内側へ延在された状態で収納され、乗員の頭部の側方に膨張展開される頭部チャンバ44Cと、シートバック18における車両幅方向外側の側部18Aに設けられて上下に延在されると共に、腰部チャンバ44Bの膨張圧により破断される下側破断予定部60と、シートバック18の上部をシート幅方向に延在されると共に、頭部チャンバ44Cの膨張圧により破断される上側破断予定部62と、を有する。【選択図】図3
