Because the two sides of the seat ring 32 are overlapped with the seat cushion rods 3 in parallel, the seat ring can be strengthened by adopting a riveting method, and the seat ring and the seat cushion rods can also be fused and omitted, namely the seat cushion rods 3 bent into a U shape are directly used, similar to the scheme of figure 2, the difference is that the bending section X of the first supporting rod 1 is lengthened, the middle section Y lifted by the seat cushion rods 3 forms a backrest support, and the direction of the seat is just opposite to that of the scheme of figure 2.

The advantage of the open seat ring 32 is that, in addition to saving a section of material, the two legs of the seated person are supported by the fabric of the seat cushion 301 and the webbing 303 to avoid the foreign body sensation on the bar, and the seated person is comfortable. The design of the open seat ring is also suitable for any style of seat ring model.

In summary, if the two sides of the modeling backrest ring 32 are overlapped with the two cushion rods 3, the two sides can be combined for reducing and saving treatment, and can also be overlapped and reinforced; if the seat cushion rod 3 and the seat ring 32 cannot be overlapped, a widened area is formed, namely, an armrest part for placing the arm is formed, and the comfort is improved. The open seat ring 32 solution is still suitable for circular shape; an oval shape; a rectangle shape; a triangle shape; a pentagon shape; a hexagon; an octagon; a trapezoid shape; a gourd-shaped seat ring and the like. In addition, when the seat frame 100 is folded, the rear portion of the seat ring 32 or the seat cushion rod 3 is lifted up, and the first support rod 1 and the shaft rod 4 are pulled upward.

In addition, during assembly, in consideration of the position relationship, the first support rod 1 is hinged to the shaft rod 4, the second support rod 2 is rotatably hinged to the rotary table 5, and the seat cushion rod 3 is hinged to the seat ring 32 by using sheet metal parts.
