To provide a pedestrian-protecting airbag device capable of eliminating the possibility that a pedestrian fallen down on a front hood drops on the ground surface.SOLUTION: Upon a contact with a pedestrian, an airbag body 13 is inflated and expanded from an airbag module 4 at a front end of a front hood 5 such that an upper surface of the front hood 5 is covered with a base expansion part 20, and a large number of capturing columns 21 forming a rectangular parallelepiped are inflated upward on the base expansion part 20. Each part of the pedestrian is fitted and captured in a capturing pocket 22 between certain neighboring capture columns 21, and impact is absorbed by the base expansion part 20. An upward opening in the capture pocket 22 is narrowed by curved deformation of the base expansion part 20 having received the weight of the pedestrian to prevent upward separation of each part of the pedestrian. Also, the pedestrian is retained on the front hood 5 by regulating the movement in the lateral and longitudinal directions by the capture column 21.SELECTED DRAWING: Figure 4

    【課題】フロントフード上に倒れ込んだ歩行者が地面に落ちる可能性を解消できる歩行者保護用エアバッグ装置を提供する。【解決手段】歩行者との接触時に、フロントフード5の前端部のエアバッグモジュール4からエアバッグ袋体13を膨張展開させて、ベース展開部20によりフロントフード5の上面を覆うと共に、ベース展開部20上で直方体状をなす多数の捕捉柱21を上方に向けて膨張させる。隣り合う何れかの捕捉柱21の間の捕捉ポケット22内に歩行者の各部位をはまり込ませて捕捉し、ベース展開部20で衝撃吸収する。歩行者の重量を受けたベース展開部20の湾曲変形により捕捉ポケット22の上方への開口部を狭めて、歩行者の各部位の上方への離脱を防止すると共に、捕捉柱21により左右及び前後方向への移動を規制し、歩行者をフロントフード5上にとどめる。【選択図】図4
