PROBLEM TO BE SOLVED: To provide a head protection airbag device in which expansion and inflation of the end side inflation part of an airbag can be completed quickly.SOLUTION: The airbag 20 of a head protection device comprises a main inflation part 29 and an end side inflation part 35 which is arranged at the front end 21c side of the airbag as a downstream side of inflation gas G with respect to the main inflation part. Between the main inflation part and the end side inflation part, a boundary closing part 50 is arranged so as to partition the main inflation part and the end side inflation part. The boundary closing part 50 is provided, between the upper edge 42a side and the lower edge 42b of a periphery part 42 at the periphery of a gas flow-in part 22 of the airbag, with flow ports 36, 37 in which the inflation gas can be made to flow from the main inflation part to the end side inflation part 35 side, and is configured to comprise a vertical closing part 52 which is arranged along an almost vertical direction to the lower part side and an oblique closing part 54 which extends the oblique upper direction of the main inflation part side from the vicinity of the upper end 52a of the vertical closing part.SELECTED DRAWING: Figure 3

    【課題】エアバッグの端側膨張部の展開膨張を迅速に完了させることができる頭部保護エアバッグ装置を提供すること。【解決手段】頭部保護エアバッグ装置のエアバッグ20が、主膨張部29と、主膨張部より膨張用ガスGの下流側として、エアバッグの前端21c側に配置される端側膨張部35と、を備える。主膨張部と端側膨張部との間には、主膨張部と端側膨張部とを区画するように、境界閉じ部50が配置される。境界閉じ部50は、エアバッグのガス流入部22の周縁の周縁部42の上縁42a側と下縁42b側とのそれぞれの間に、主膨張部からの膨張用ガスを端側膨張部35側に流し可能な流通口36,37を設けるとともに、下部側に略上下方向に沿って配置される縦閉じ部52と、縦閉じ部の上端52a付近から主張膨張部側の斜め上方に延びる傾斜閉じ部54と、を備えて構成される。【選択図】図3
