PROBLEM TO BE SOLVED: To provide a head protection airbag device capable of ensuring the smooth deployment of an airbag down to a lower edge even if the airbag includes a pillar cover section inflating to cover a vehicle inner side of an intermediate pillar part.SOLUTION: An airbag 20 comprises: window cover sections 27 and 35 deploying and inflating from a storage portion SP downward and covering vehicle inner sides of front and rear windows W1 and W2, respectively during the flow of inflation gas G into the window cover sections 27 and 35; and a pillar cover section 40 covering a vehicle inner side of an intermediate pillar part CP between the front and rear windows W1 and W2. The pillar cover section 40 includes an inlet port 41 provided in an upper portion, communicating with the front window cover section 27, and causing the inflation G to flow into the pillar cover section 40, and further includes an upper inflation section 42 extending from the inlet port 41 in a front-rear direction; and a lower inflation section 43 extending downward from an end portion, away from the inlet port 41, of the upper inflation section 42, extending in the front-rear direction so as to be inverted, and having a closed tip end portion 43b provided near a lower portion of the inlet port 41. The pillar cover section 40 inflates and completes inflating by the inflation gas G flowing into the pillar cover section 40 from the inlet port 41.

    【課題】中間ピラー部の車内側を覆うように膨らむピラーカバー部を備えていても、エアバッグの下縁までの円滑な展開を確保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、膨張用ガスGの流入時に、収納部位SPから下方に展開膨張し、前後の窓W1,W2の車内側を覆う窓カバー部27,35と、前後の窓の間の中間ピラー部CPの車内側を覆うピラーカバー部40と、を備える。ピラーカバー部は、上部側に、前窓カバー部27と連通して、膨張用ガスGを流入させる流入口41を備え、さらに、流入口41から前後方向に延びる上側膨張部42と、上側膨張部42の流入口41から離れた端部で下方に延び、かつ、反転するように前後方向に延びて、流入口41の下方付近に、閉塞された先端部43bを設けてなる下側膨張部43と、を備える。ピラーカバー部は、流入口41から流入する膨張用ガスGにより、膨張し、かつ、膨張を完了させる。【選択図】図7
