PROBLEM TO BE SOLVED: To provide a head protection airbag device capable of protecting the head of a passenger moving to the outside of a vehicle by an airbag having a predetermined portion inflating to be thick.SOLUTION: A head protection airbag device of the present invention comprises a thick reception section 34 inflating to be thick so that an inflation shield portion 20 of an airbag 19 can receive the head of a passenger. The length of the airbag 19 in a front-rear direction in a state in which the airbag 19 deploys flat is set larger than the length of the inflation shield portion 20 in the front-rear direction at a time of completion of inflation. The airbag 19 includes length restricting connected sections 37, 37 arranged on an upper end 34a and a lower end 34b of the thick reception section 34, respectively formed by connecting a vehicle inner sidewall section 23a to a vehicle outer sidewall section 23b so that the length in the front-rear direction of the airbag 19 is reduced to generally match the length of the inflation shield portion 20 at the time of completion of inflation.

    【課題】車外側に向かって移動する乗員の頭部を、所定の箇所を厚く膨張させたエアバッグによって、的確に保護可能な頭部保護エアバッグ装置を提供すること。【解決手段】本発明の頭部保護エアバッグ装置では、エアバッグ19の膨張遮蔽部20が、乗員の頭部を受け止め可能に、厚肉に膨張する厚肉受止部34を備えている。エアバッグ19が、平らに展開した状態の前後方向側の長さ寸法を、膨張完了時の膨張遮蔽部20の前後方向側の長さ寸法より大きく設定される。エアバッグ19が、車内側壁部23aと車外側壁部23bとを結合させた厚肉受止部34の上端34a側と下端34b側とに、前後方向側の長さ寸法を、膨張完了時の膨張遮蔽部20の前後方向側の長さ寸法と略一致させるように、縮めるような長さ規制結合部37,37を、配置させている。【選択図】図2
