The support 30 includes two front legs 32 and two rear legs 34, the two front legs 32 and the two rear legs 34 are respectively disposed at the left side and the right side of the seat board assembly 10, the front legs 32 and the rear legs 34 at the same side of the seat board assembly 10 are hinged together in a rotating way, the front legs and the rear legs are in an intersection structure when opened, and the front legs and the rear legs are overlapped in a plane when folded. The backrest module 20 is connected to the armrest mechanism 40. The armrest mechanism 40 includes two armrest rods 42 respectively disposed on the left and right sides of the seat plate assembly 10, the top of the front leg 32 is rotatably hinged to the rear portion of the armrest rod 42, and the top of the rear leg 34 is rotatably and slidably connected to the front portion of the armrest rod 42. The front portion of the seat pan assembly 10 is rotatably coupled to the armrest mechanism 40, and the armrest lever or seat pan assembly is provided with a blocking structure 50. When the folding chair is opened, the blocking structure 50 limits the top of the rear leg 34 to continue sliding along the front end of the grab rail 42, and the support frame 30 or the backrest module 20 provides support to the rear portion of the seat plate module 10, preventing the rear portion of the seat plate module 10 from turning downward.

The front leg 32 is located inside the rear leg 34, and when the folding chair is folded, the rear leg 34 and the grab rail 42 are close together, minimizing the volume in the folded state.

The support frame 30 further includes a support bar connected between the front legs 32, with the hinge points of the front and rear legs being at the base of the seat pan assembly 10. The support bar 32 is supported on the rear of the bottom surface of the seat plate assembly 10 when the folding chair is unfolded, and provides the support to the rear of the seat plate assembly 10. It will be appreciated that there may also be a pivotal and slidable connection between the front legs 32 and the seat pan assembly 10, the front legs 32 providing support for the rear of the seat pan assembly 10, in particular: if the front leg 32 is provided with a seat cover, the seat cover is rotatably hinged on the front leg 32, and the seat cover is slidably connected with the seat board assembly 10, or the side edge of the seat board assembly 10 is provided with a long strip chute, the front leg 32 is provided with a guide pillar, and the guide pillar is inserted into the long strip chute. Whether in the form of a support bar, a seat cover, or a long chute and guide post, the support bracket 30 provides support to the rear of the seat pan assembly 10.
