The two ends of the seat frame rear transverse tube 130 are respectively connected with the base through height adjusting connecting rods 800, the two height adjusting connecting rods 800 are right-left opposite, the lower ends of the height adjusting connecting rods 800 are hinged with the rear portion of the vertical plate 220, and the upper ends of the height adjusting connecting rods are welded with the seat frame rear transverse tube 130, so that the seat frame 100 can be rotatably connected with the seat frame. Two link mechanisms are arranged between the left side and the right side of the front part of the seat frame 100 and the base respectively, the two link mechanisms are right opposite to each other left side and right side, and the two link mechanisms are rotatably connected with the base and the seat frame 100. Thus, the seat frame 100, the base, the two-bar linkage, and the height adjustment link 800 form a five-bar linkage. A high-tone assembly 900 is connected to any one of the high-tone links 800. The two link mechanisms are respectively connected with a rotation driving mechanism, the rotation driving mechanism is connected with any one of the two link mechanisms correspondingly, the rotation driving mechanism is right-left, a synchronous rotating rod is connected between the rotation driving mechanism and the two, the synchronous rotating rod is connected with an inclination angle adjusting driving device, and the inclination angle adjusting driving device drives the two rotation driving mechanisms to work or keep the two rotation driving mechanisms locked.

Further, since the recliner 500 is connected to the rotation driving link 300 through the reduction gear mechanism formed by the two-stage gear mechanism, the angle adjusting speed of the seat frame 100 can be controlled within an appropriate speed range. On the other hand, the load of the seat frame 100 is transmitted to the recliner 500 through the secondary gear mechanism, and the load borne by the recliner 500 is smaller than the load on the seat frame 100, so that the requirement on the bearing performance of the recliner 500 is reduced, the product selection range of the recliner 500 is expanded, and the cost control is facilitated.
Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
