To provide a head protection airbag device which can stably deploy and inflate an airbag during deployment and inflation on a vehicle inner side.SOLUTION: A head protection airbag device includes: an airbag which is folded and stored along a longitudinal direction on an upper edge side of a window on a vehicle inner side of a vehicle and deploys and inflates downward so as to cover the vehicle inner side of the window during inflow of inflation gas from an inflator. The airbag 20 has a window shielding inflation section 27 for covering the vehicle inner side of the window. A folding shape 61 of the window shielding inflation section 27 is configured to have an inner roll folding section 62 roll-folding toward the vehicle inner side I so that a lower edge 20b side of the airbag is made closer to an upper edge 20a side and an outer roll folding section 64 roll-folding toward a vehicle outer side O so that the inner roll folding section is made closer to the upper edge side of the airbag while arranging the inner roll folding section on a center 64a side.SELECTED DRAWING: Figure 3
【課題】展開膨張時のエアバッグを、安定して、車内側で展開膨張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】車両の車内側における窓の上縁側に、前後方向に沿うように折り畳まれて収納され、インフレーターからの膨張用ガスの流入時に、窓の車内側を覆うように下方へ展開膨張するエアバッグを備えて構成される頭部保護エアバッグ装置。エアバッグ20は、窓の車内側を覆う窓遮蔽膨張部27、を備える。窓遮蔽膨張部27の折畳形状61は、エアバッグの下縁20b側を上縁20a側に接近させるように、車内側Iに向けてロール折りする内ロール折部62と、内ロール折部を中心64a側に配置させつつ、エアバッグの上縁側に接近させるように、車外側Oに向けてロール折りする外ロール折部64と、を備えて構成される。【選択図】図3
