Abstract
A cross folding mechanism of a folding chair comprises two back feet rods, two front feet rods, two pairs of long cross folding plates and two pairs of short cross folding plates. The back feet rods and the front feet rods are respectively provided with pedestals, joint covers and joint seats from bottom to top. The four end parts of the two pairs of long cross folding plates are respectively articulated with the joint seat and the pedestal of the two front feet rods and the joint seat and the pedestal of the two back feet rods to form the front face and the back face of the whole structure. The four end parts of the two pairs of short cross folding plates are articulated between the joint seat and the joint cover of one back foot rod and one front foot rod at same side to form a left face and a right face with less area than the front and back faces, which ensures that when the whole folding chair is spread, the planform of which is a rectangle. The cross folding mechanism ensures that when the folding chair is spread, the planform is a rectangle that means a chair face is a rectangle, front and back edges are longer than left and right edges, which not only is in accordance with the characteristic of ergonomics but also can save material and reduce cost.
