PROBLEM TO BE SOLVED: To provide a head-protective airbag device capable of adequately protecting an occupant head at oblique collision by significantly protruding inside a vehicle, an end side inflation part arranged at an end side in a cross direction and a central side inflation part adjacent to the end side inflation part on completion of airbag inflation.SOLUTION: A head-protective airbag device is provided with an airbag 20 comprising a bag body 21, a tension belt 51 extending from the front end side of the bag body 21, and a tether 54 covering the outer peripheral side of the bag body 21. The bag body 21 has an end side inflation part 33 and a central side inflation part 34, and the tension belt 51 is arranged nearly along a cross direction so as to position at a vehicle outside O of the end side inflation part 33 on completion of inflation in the bag body 21. The tether 54 is inserted in a slit formed at a partition part and covers the vehicle inside I of the end side inflation part and the vehicle outside O of the central side inflation part 34.

    【課題】エアバッグの膨張完了時に、前後方向の端部側に配置される端側膨張部と、端側膨張部に隣接される中央側膨張部と、を、車内側に大きく突出させることができて、斜突時に乗員の頭部を的確に保護可能な頭部保護エアバッグ装置の提供。【解決手段】頭部保護エアバッグ装置では、エアバッグ20が、バッグ本体21と、バッグ本体21の前端側から延びるテンションベルト51と、バッグ本体21の外周側を覆うテザー54と、を備える。バッグ本体21が、端側膨張部33と中央側膨張部34とを備える。テンションベルト51が、バッグ本体21の膨張完了時に、端側膨張部33の車外側Oに位置するように、前後方向に略沿って配置される。テザー54が、区画部に形成されるスリットを挿通させて、端側膨張部33の車内側Iと、中央側膨張部34の車外側Oと、を覆う。【選択図】図7
