[0002] Folding chairs are very common in our daily life, and their folding function greatly facilitates our operation and use. The existing folding chairs in our daily life are generally classified into three materials: wood, plastic and metal. The structures are also similar, basically front / rear legs plus seat and backrest. The folding mechanism is mostly a four-bar folding mechanism, a telescopic sliding folding structure, and a rotating shaft folding mechanism. The load-bearing strength also meets the general daily use requirements.
[0003] For existing folding seats, the load-bearing strength is widely applicable to the general public. However, for users with heavier weight, the load-bearing strength of the seats poses a certain risk of collapse. The industry standard seat safety load-bearing requirements of some countries are difficult to meet. In order to meet the relatively high load-bearing safety standards, the only way is to increase costs to thicken, strengthen, and harden the products. In this way, even if the industry's high load-bearing safety standards are met, the cost investment for manufacturers has increased. Utility Model Content
