To prevent heat generated by an inflator from reaching a connection member that connects end parts of a first webbing and a second webbing with each other in a storage part of a cushion member storing an airbag and the inflator.SOLUTION: A headrest comprises: side frames 54 disposed inside a cushion member 20 in which a storage part 40 is formed; a skin material 76 covering a surface of the cushion member; an airbag 74 stored in a folded state in the storage part; an inflator 64 disposed in the storage part; a first webbing 92 where one end part 92A is connected to a cleavage; a second webbing 96 where the one end part 96A is connected to the cleavage and the other end part 96B is connected to the other end part 92B of the first webbing; and a connection member 98 that connects the other end parts of the first webbing and the second webbing with each other in the storage part. As viewed along an axis line 64X of the inflator, front end parts 58 of the side frames are located in front of the inflator and the connection member is located in front of the front end parts of the side frames.SELECTED DRAWING: Figure 5
【課題】エアバッグ及びインフレータを収納するクッション部材の収納部内において第1力布及び第2力布の端部どうしを接合する接合部材に、インフレータが発生する熱を及び難くする。【解決手段】収納部40が形成されたクッション部材20の内部に設けられたサイドフレーム54と、クッション部材の表面を覆う表皮材76と、収納部に折り畳まれた状態で収納されるエアバッグ74と、収納部に設けられたインフレータ64と、一端部92Aが開裂部に接続された第1力布92と、一端部96Aが開裂部に接続され且つ他端部96Bが第1力布の他端部92Bに接続された第2力布96と、収納部において第1力布及び第2力布の他端部どうしを接合する接合部材98と、を備え、インフレータの軸線64Xに沿って見たときに、サイドフレームの前端部58がインフレータより前方に位置し且つ接合部材がサイドフレームの前端部より前方に位置する。【選択図】図5
