The invention relates to a zero-gravity linkage adjusting mechanism for a backrest and a cushion of an automobile seat. The zero-gravity linkage adjusting mechanism comprises a linkage piece, a rotating support, a cushion spring, a connecting piece and a tension spring. The upper end of the linkage piece is hinged to the backrest, and a limiting sliding groove is formed in the lower end of the linkage piece and used for being connected with the rotating support. The rear end of the rotating support is arranged in the limiting sliding groove of the linkage piece, the front end of the rotating support is arranged in the connecting sliding groove of the connecting piece, and the middle of the rotating support is clamped on the seat frame rear cross beam and rotates around the seat frame rear cross beam; the front end of the cushion spring is hinged with the seat frame, and the rear end of the cushion spring is fixedly connected with the connecting piece; the connecting piece is provided with a connecting sliding groove connected with the rotating support and a lap joint part in lap joint with the rotating support. The rear end of the tension spring is fixed on the sliding rail, and the front end of the tension spring is fixed on the cushion spring in an inclined upward mode. The adjusting mechanism is good in stability performance, the independent adjusting angle of the backrest can be freely adjusted according to requirements, and the independent adjusting angle of the backrest can be changed only by changing one part.
