PROBLEM TO BE SOLVED: To improve deployment performance of an air bag body in a vertical direction, and suppress a seat pad part from being deformed forward when a side part of the seat back is grasped.SOLUTION: A seat back 14 consisting of a part of a vehicle seat is provided in which a part of a side part of a seat pad part 15 is hollowed out to form a storage part 16. An air bag body 41 is developed in the front direction by inflation gas and expanded in at least a vertical direction to be larger in size than the storage part 16. The air bag body 41 is folded to be a storage form and integrated into the storage part 16. A vertical direction development facilitating parts (upper slit 21, lower slit 22) is arranged at portions adjacent to sides farther from the storage part 16 in the vertical direction of the storage part 16 in the seat pad part 15 so that the portions become more deformable in the vertical direction than the front direction to facilitate development of the air bag body 41 in the vertical direction.

    【課題】エアバッグ本体の上下方向の展開性能を向上させつつ、シートバックの側部が掴まれた場合にシートパッド部が前方へ変形するのを抑制する。【解決手段】車両用シートの一部をなすシートバック14には、シートパッド部15の側部の一部を刳り貫くことにより収納部16を形成する。膨張用ガスにより前方へ向けて展開して、少なくとも上下方向に収納部16よりも大きな寸法で膨張するエアバッグ本体41を、折り畳むことにより収納用形態にして収納部16内に組込む。シートパッド部15において、収納部16の上下方向について同収納部16から遠ざかる側に隣接した箇所には、同箇所を前方よりも上下方向へ変形しやすくすることにより、エアバッグ本体41の上下方向への展開を促進する上下方向展開促進部(上スリット21、下スリット22)を設ける。【選択図】図4
