The invention discloses a seat rotation position arrangement method, a seat framework, a seat and a vehicle, and the method comprises the following steps: determining an included angle alpha corresponding to the switching of the seat between an initial position and a zero gravity position, and determining a corresponding human body H point position A when the seat is at the initial position; establishing a coordinate system, and drawing a function image which passes through the position A and takes # imgabs0 # as a slope in the coordinate system; a rotational position B is determined at a position on or near the function image. According to the arrangement method, the gravity center of the passenger after the passenger is switched to the zero-gravity sitting position can be reduced, the situation that the comfort is reduced due to the fact that the overhead space of the passenger is narrow is avoided, and the situation that a seat adjusting motor needs extra work and needs a high-power adjusting motor is also avoided.

    本发明公开了一种座椅旋转位置布置方法、座椅骨架、座椅和车辆,包括以下步骤:确定座椅在初始位置和零重力位置之间切换所对应的夹角α,并确定座椅在初始位置时对应的人体H点位置A;建立坐标系,在所述坐标系内绘制过位置A并以#imgabs0#为斜率的函数图像;在所述函数图像上或靠近所述函数图像的位置确定旋转位置B。本发明的布置方法能够降低乘坐人员在切换至“零重力”乘坐位后的重心,避免了乘坐人员头顶空间狭窄而降低舒适性的情况,也避免了座椅调节电机需要额外做功而需要较大功率的调节电机的情况。
