The invention provides a back plate mounting structure of a seat back and a vehicle seat. The back plate mounting structure of the seat back comprises a guide wire mounted to a back plate and having awidthwise extension portion extending in a widthwise direction of a seat back frame on a front end side or a base side of the seat back frame, and a holder having a base portion rotatably supportingthe widthwise extension portion about the axis and an attachment portion attached to the seat back frame. When a force greater than or equal to a predetermined value in a direction in which the holderis detached from the seat back frame due to a force from the back of an occupant received by the back plate is applied to the holder from the widthwise extension portion, the widthwise extension portion is detached from the base portion or the holder is detached from the seat back frame, and thus, the widthwise extension portion is separated from the seat back frame.
本发明提供一种座椅靠背的靠背板安装结构及交通工具用座椅,该座椅靠背的靠背板安装结构具备:导丝,其安装于靠背板,且在座椅靠背框架的前端侧或根基侧具有沿座椅靠背框架的宽度方向延伸的宽度方向延伸部;以及保持件,其具有将宽度方向延伸部绕轴线旋转自如地支撑的基部和安装于座椅靠背框架的安装部。在从宽度方向延伸部对保持件赋予由靠背板承受的来自乘员的背的力引起的从座椅靠背框架脱离的方向的预定值以上的力的情况下,宽度方向延伸部从基部脱离,或者保持件从座椅靠背框架脱离,从而宽度方向延伸部从座椅靠背框架分离。
