[0084] Example 1

[0085] When the folding chair of this embodiment is used, taking five cross braces as an example, the five cross brace structures are used as neck bars, two front and rear shoulder bars and two front and rear footrest bars respectively. After use, the chair body can be folded and transferred in a sheet-like shape. The two folded side supports 1 can also be further separated to bring the sheet-like state into a columnar state, and then stored in a storage bag for transportation, thereby improving portability and reducing space occupation. At the same time, because the seat cloth 2 and the back cloth 3 are flexible, the two folded side supports 1 can also be placed in adjacent gaps respectively, providing more storage possibilities.

[0086] Example 2

[0087] When the folding chair of this embodiment is used, taking the three cross braces as an example, the three cross brace structures are respectively used as the neck bar and the two front and rear carrying bars, and are respectively connected to the two front legs 103 and the two rear legs 104 through two limit rods. After use, the chair body can be folded and transferred in a sheet-like state, and the two folded side supports 1 can be further separated by separating the cross brace structures, so that the sheet-like state is changed into a columnar state, and then stored in a storage bag for transportation, thereby improving portability and reducing space occupation. At the same time, because the seat cloth 2 and the back cloth 3 are flexible, the two folded side supports 1 can also be placed in adjacent gaps respectively, providing more storage possibilities.

[0088] Example 3

[0089] Taking five cross bracing structures as an example, the five cross bracing structures are used as neck bars, two front and rear carrying bars and two staggered footrests (the two cross bracing structures are X-shaped, and the arc sections are rotated to avoid and cooperate with each other). After use, at least two staggered cross bracing structures must be disassembled first, and then the chair body can be folded and transferred in a sheet-like state. The remaining cross bracing structures can also be further separated to bring the two folded side supports 1 closer to each other, changing the sheet-like state into a columnar state, and then stored in a storage bag for transportation, thereby improving portability and reducing space occupied. At the same time, because the seat cloth 2 and the back cloth 3 are flexible, the two folded side supports 1 can also be placed in adjacent gaps, providing more storage possibilities.

[0090] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
