The invention provides an adjusting device for a zero-gravity posture seat framework, and belongs to the technical field of seat adjusting devices. The adjusting device of the zero-gravity posture seat framework comprises a four-connecting-rod mechanism used for adjusting the height of a seat cushion framework, a fifth rotating piece located at the joint of the seat cushion framework and a backrest framework and a lead screw motor arranged on the four-connecting-rod mechanism. The four-connecting-rod mechanism is arranged on a cross beam of the seat cushion framework, the four-connecting-rod mechanism is composed of a first rotating piece, a second rotating piece, a third rotating piece and a fourth rotating piece which are sequentially and rotationally connected through connecting pieces, and the second rotating piece moves relative to the fourth rotating piece; the lead screw motor is used for driving the first rotating piece and the third rotating piece to stretch out and draw back. According to the adjusting device for the zero-gravity posture seat framework, adjustment of the zero-gravity posture of the seat framework can be achieved.
