To provide a head protection airbag device which can be quickly deployed without using a different component, and can generate tension which is sufficient for an airbag main body.SOLUTION: An airbag 20 comprises a bag main body 21 which is deployed and expanded so as to cover the vehicle inside of a window W, and a strap 70 for attaching an upper-side end part 71 to an upper frame 3a of the window 3, attaching a lower-side end part 76 to a lateral frame 3c, and connecting an intermediate region 73 to the bag main body. In the strap, an insertion part 74 inserted into an insertion hole 48 of the bag main body is arranged at the intermediate region 73, and a region from the upper-side end part up to the insertion part is set as a vehicle outside region 81 which is arranged at the vehicle outside of the bag main body in an expansion finish state, and a region from the insertion part up to the lower-side end part is set as a vehicle inside region 82 which is arranged at the vehicle inside of the bag main body in an expansion finish state. The vehicle inside region is pressed to the vehicle inside by the expansion region 27 at a finish of the expansion of the bag main body, generates tension at the strap 70, and also generates tension at the bag main body.SELECTED DRAWING: Figure 6
【課題】別部品を利用せずに、バッグ本体を迅速に展開できて、バッグ本体に十分なテンションを発生させることができる頭部保護エアバッグ装置の提供。【解決手段】エアバッグ20が、窓Wの車内側を覆うように展開膨張するバッグ本体21と、上側端部71を窓枠3の上枠3aに取り付け、下側端部76を、横枠3cに取り付けて、中間部位73をバッグ本体に連結させるストラップ70と、を備える。ストラップは、中間部位73に、バッグ本体の挿通孔48を挿通する挿通部74、を配設させて、上側端部から挿通部までを、膨張完了状態のバッグ本体の車外側に配置される車外側部位81とし、挿通部から下側端部までを、膨張完了状態のバッグ本体の車内側に配置される車内側部位82とする。車内側部位が、バッグ本体の膨張完了時、膨張部位27により、車内側に押圧されて、ストラップ70にテンションを発生させて、バッグ本体にもテンションを発生させる。【選択図】図6
