The invention relates to an adjusting spring assembly for a seat suspension. The adjusting spring assembly comprises a sliding plug cylinder and a cavity spring which is pressed between an upper plug cap and a lower plug cap by the upper plug cap and the lower plug cap jointly, wherein the upper plug cap and the lower plug cap can vertically slide in an inner cavity of the sliding plug cylinder; a plug rod arranged at the upper part of the upper plug cap extends out of the upper end of the sliding plug cylinder; a plug rod arranged at the lower part of the lower plug cap extends into a guide hole in the lower part of the sliding plug cylinder; a spring is arranged between the lower plug cap and the lower end of the sliding plug cylinder; the cavity spring is provided with an upper cover an a lower cover which are mutually buckled; the spring is arranged in a cavity formed by the upper cover and the lower cover jointly. According to the adjusting spring assembly disclosed by the invention, the plug rods are connected with a seat with external threads and are driven by a motor to rotate, so that the upper plug cap adjusts the compression amount of the cavity spring and the compression amount of the spring in an internal up-down moving manner and controls the integral rigidity of the integral spring assembly, so that the vibration frequency of an automobile seat is intervened, and the comfortableness of human bodies is guaranteed.
