To provide a crewman protection device which can accurately protect also a head in addition to an upper half body of a crewman by an air bag of which expansion has been completed.SOLUTION: A crewman protection device S for protecting a crewman MP who sits on a seat 1 comprises a seat belt 7, and an air bag 25 located in an area of a lap belt 10 in the seat belt. The air bag comprises: a body expansion part 28 which is folded and is stored in a storage part provided on the lap belt, and can protect an upper half body MU of the crewman at the time of expansion completion; and a head protection part 42 which is formed on an upper end side of the body expansion part at the time of expansion completion, and can protect a head MH of the crewman. The head protection part has: a front side expansion part 43 which covers the front of the head; and edge side expansion parts 44L, 44R which extend backward from both end sides in a longitudinal direction of the front side expansion part so as to cover the side of the head. The edge side expansion part is so arranged as to provide a gap H between itself and the head at the time of expansion completion of the air bag.SELECTED DRAWING: Figure 12
【課題】膨張を完了させたエアバッグにより、乗員の上半身に加えて、頭部も的確に保護可能な乗員保護装置を提供すること。【解決手段】シート1に着座した乗員MPを保護するための乗員保護装置S。シートベルト7と、シートベルトおけるラップベルト10の領域に配置されるエアバッグ25と、を備える。エアバッグが、折り畳まれてラップベルトに設けられた収納部位内に収納されるとともに、膨張完了時に乗員の上半MUを保護可能な本体膨張部28と、膨張完了時に本体膨張部の上端側に形成されて乗員の頭部MHを保護可能な頭部保護部42と、を備える。頭部保護部が、頭部の前方を覆う正面側膨張部43と、正面側膨張部の左右方向の両端側から後方へ延びて頭部の側方を覆うように縁側膨張部44L,44Rと、を有する。縁側膨張部は、エアバッグの膨張完了時に、頭部との間に隙間Hを設けるようにして、配置される。【選択図】図12
