The invention discloses a seat framework, an automobile seat and an automobile. The seat framework comprises a cushion framework and at least one supporting leg assembly, the supporting leg assembly comprises a front leg, a rear leg, a first connecting rod and a second connecting rod, the two ends of the first connecting rod are in pivot joint with the middle of the front leg and the middle of the rear leg respectively, one end of the second connecting rod is in pivot joint with the middle of the first connecting rod, and the other end is connected to a floor; the second connecting rod includes a flexible part constituting at least a partial rod section of the second connecting rod. In the invention, the flexible part enables the second connecting rod to have a telescopic margin in the length direction, so that the requirement on the mounting precision of the second connecting rod can be reduced; when the seat framework rotates backwards with the lower end of the rear leg as the fulcrum, at least the front side of the cushion framework is lifted upwards, the flexible part does not apply force to the first connecting rod, the first connecting rod cannot drive the front leg to be folded towards the cushion framework, the front leg is lifted upwards, and direct friction interference between the front leg and the floor is avoided.
本发明公开一种座椅骨架、汽车座椅及汽车,座椅骨架包括坐垫骨架和至少一个支腿组件,支腿组件包括前腿、后腿、第一连杆和第二连杆,第一连杆的两端分别枢接前腿的中部和后腿的中部,第二连杆的一端枢接第一连杆的中部,另一端用于连接至地板;第二连杆包括构成第二连杆的至少部分杆段的柔性部。本发明中,柔性部使得第二连杆在长度方向具有伸缩余量,能够降低对第二连杆的安装精度的要求;座椅骨架以后腿的下端为支点向后旋转时,坐垫骨架的至少前侧向上抬起,柔性部未对第一连杆施力,第一连杆无法驱动前腿朝向坐垫骨架折叠,使得前腿向上抬起,避免与地板之间直接产生摩擦干涉。
