To provide a passenger protection device for a front passenger seat in which passenger restraining performance of an airbag is easily ensured even when an inclination of a windshield is large, and an instrument panel has a compact size.SOLUTION: In a passenger protection device 10 for a front passenger seat, upon a front collision of a vehicle 12, a lower air bag 52 which is inflated and deployed from an instrument panel reinforcement 28 quickly restrains left and right lower leg parts LL and RL of a passenger P while being supported by a dashboard 24 including an instrument panel 26. Further, in this case where an upper airbag 42 which is inflated and deployed from a front header 20F arranged near a head part H of the passenger P restrains the head part H while being supported by a windshield 18. In the windshield 18, an upper end part is joined to the front header 20F, so that the upper airbag 42 which is inflated and deployed from the front header 20F can be uses in a wide range in a height direction in the windshield 18 as a support surface (reaction force surface).SELECTED DRAWING: Figure 1

    【課題】ウインドシールドの傾きが大きく且つインストルメントパネルが小型な場合でも、エアバッグの乗員拘束性能を確保し易い助手席用乗員保護装置を得る。【解決手段】助手席用乗員保護装置10では、車両12が前面衝突した際には、インパネリインフォースメント28から膨張展開する下方エアバッグ52が、インストルメントパネル26を含むダッシュボード24によって支持されつつ、乗員Pの左右の下腿部LL、RLを早期に拘束する。またこの際には、乗員Pの頭部Hの近くに配置されるフロントヘッダ20Fから膨張展開する上方エアバッグ42が、ウインドシールド18によって支持されつつ、頭部Hを拘束する。ウインドシールド18は、上端部がフロントヘッダ20Fと結合されているので、フロントヘッダ20Fから膨張展開する上方エアバッグ42は、ウインドシールド18における上下の広い範囲を支持面(反力面)として利用することができる。【選択図】図1
