To provide an occupant protection device capable of enhancing an occupant protection function at collision of a vehicle.SOLUTION: An occupant protection device allows a belt airbag 300 to be deployed without prohibiting delivery of a seat belt (webbing 210) for a predetermined time when a distance from a storage position (instrument panel 7) of a main airbag 31 to an occupant P (or a seat 10 the occupant P is seated) is long, thereby, the belt airbag 300 can be inflated to a sufficient size, and movement of an upper body of the occupant P can be restricted without depending on the main airbag 31, so as to enable protection of the occupant P, especially appropriate protection of a neck by reducing forward and backward movement of a head.SELECTED DRAWING: Figure 1
【課題】車両の衝突時に、乗員保護機能を高めることができる乗員保護装置を提供する。【解決手段】乗員保護装置は、メインエアバッグ31の収納位置(インストルメントパネル7)から乗員P(または乗員Pが着座した座席シート10)までの距離が離れている場合に、シートベルト(ウェビング210)の繰り出しを所定時間禁止させずに、ベルトエアバッグ300を展開させるので、ベルトエアバッグ300を十分な大きさまで膨張させることができ、メインエアバッグ31によらずとも、乗員Pの上体の移動を制限でき、乗員Pの保護、特に、頭部の前後動を小さく、頸部を適切に保護することができる。【選択図】図1
