To provide a head protection airbag device that can inhibit interference with an airbag, which is inflated adjacently at a cabin side, during inflation, and is capable of adequately protecting a head of a crew member when at an oblique collision or at an off-set collision.SOLUTION: An airbag is arranged at a front end 21c side at completion time of inflation, and comprises an end side inflation part 38 which is partitioned from another general inflation part 43 by a partition part 47 arranged at a rear side. The end side inflation part is constituted that an upper portion 39 at a top end 38a side at the completion time of inflation is arranged so as to protrude to a cabin side than a lower portion 40 at a bottom end 38b side at the completion time of inflation. The upper portion is constituted to be arranged so as to inflate a region from a rear upper area of the partition part to a front lower area of the partition part, and a protruded state into cabin side at the completion time of inflation is maintained by maintaining means 65.SELECTED DRAWING: Figure 7

    【課題】膨張時に、車内側で近接して膨張しているエアバッグとの干渉を抑制できて、かつ、斜突時やオフセット衝突時にも、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を提供すること。【解決手段】エアバッグが、膨張完了時における前端21c側に配置されるとともに、後側に配置される区画部47によって、他の一般膨張部43と区画される端側膨張部38を、備える。端側膨張部が、膨張完了時の上端38a側の上側部位39を、膨張完了時の下端38b側の下側部位40よりも車内側に突出するように配置させる構成である。上側部位が、区画部の後側上方から区画部の前側下方にかける領域を膨らませるようにして、配置される構成とされるとともに、維持手段65によって、膨張完了時の車内側への突出状態を維持される。【選択図】図7
