PROBLEM TO BE SOLVED: To provide a head protection airbag device capable of securing stable mounting strength of a guide member and easily being mounted on a vehicle body side.SOLUTION: A head protection airbag device includes: an airbag 20 deployed and inflated from an upper edge side of the vehicle inside of a window W of a vehicle V into which the airbag 20 is folded and stored during inflow of inflation gas; and a guide member 40 having a guide body section 41 which is approximately L-shaped in cross section and guides the airbag 20 in a deployment direction during deployment and inflation. The guide member 40 includes a mounting piece section 51 which is projected from the guide body section 41, has a mounting hole 52 into which a fastening member 57 fastened to a mounting portion 2a on a body 1 side is inserted and is mounted in the mounting portion 2a by the fastening member 57 fastened to the mounting portion 2a. The airbag 20 includes a connection piece 28 connected to the guide member 40 on an upper edge 20a side during the completion of deployment and inflation. The connection piece 28 includes a through hole 29 through which the mounting piece section 51 is led and is locked by the mounting piece section 51 passing through the through hole 29.

    【課題】案内部材の安定した取付強度を確保して、車体側へ容易に取付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】膨張用ガスの流入時、折り畳まれて収納された車両Vの窓Wの車内側の上縁側から展開膨張するエアバッグ20と、展開膨張時のエアバッグ20の展開方向を案内する断面略L字形の案内本体部41を有した案内部材40と、を備えて構成される。案内部材40は、案内本体部41から突設されて、ボディ1側の取付部位2aに締結される締結部材57を挿通させる取付孔52を有して、取付部位2aに締結される締結部材57により、取付部位2aに取り付けられる取付片部51、を備える。エアバッグ20は、展開膨張完了時の上縁20a側に、案内部材40に連結される連結片28を備える。連結片28は、取付片部51を貫通させる貫通孔29を備えて、貫通孔29に貫通される取付片部51に係止される構成としている。【選択図】図13
