The invention discloses a compact multi-direction adjustment zero-gravity seat framework. The seat framework comprises a base, a seat frame is arranged above the base, the rear portion of the seat frame is connected with a backrest framework through an angle adjuster, seat frame adjustment connecting rods are arranged between the front portion and the base and between the rear portion of the seat frame and the base respectively, and the seat frame adjustment connecting rods rotate in a vertical plane. Each seat frame adjustment connecting rod is hinged to the base through a hinge shaft, the seat frame adjustment connecting rod located on the rear portion of the seat frame is hinged to the seat frame, the seat frame adjustment connecting rod located on the front portion is connected with the seat frame through an inclination angle adjusting connecting rod, and the seat frame adjustment connecting rods located on the front portion and the rear portion are connected with rotation driving mechanisms respectively. The seat frame side plate of the seat frame and the backrest side plate of the backrest framework on the same side are both provided with reinforcing structures, and the rear side of the backrest side plate on the side is provided with a guide restraining mechanism used for guiding a safety belt to slide. The seat framework has the beneficial effects that height adjustment and inclination angle adjustment of the seat frame can be achieved, stable support is provided for the seat frame, and the safety of a safety belt system is guaranteed.
