[0023] The support unit is composed of a support rod 101, a lateral support rod 102, a base connecting plate 103, a top connecting plate 104, a backrest connecting hole 105, an armrest connecting hole 106 and a cushion connecting hole 107. The lateral support rod 102 is fixedly connected to the side of the support rod 101. The shape of the support rod 101 is a hexagonal column, and three arched lateral support rods 102 are distributed on the surface, and they are all made of hollow aluminum alloy. The arched design gives the support rod unique mechanical properties. The arched structure can disperse and withstand lateral forces from all directions, effectively enhancing the stability of the structure. This property enables the arched lateral support rod 102 to maintain the overall stability of the structure when it is subjected to lateral pressure, and prevent deformation or damage caused by lateral force. The arched structure also has high durability and load-bearing capacity, and can withstand greater pressure and tension. At the same time, its arched design also increases the support rod's anti-bending ability, enabling it to cope with various complex mechanical environments. The base connecting plate 103 is fixedly connected At the bottom of the support rod 101 and the lateral support rod 102, a non-slip rubber layer is provided on the connecting end surfaces of the base connecting plate 103 and the top connecting plate 104. The rubber layer is squeezed by the nut, and the reaction force of the rubber layer is used to tightly squeeze the nut and the thread on the screw, thereby generating a greater friction force. The increased friction force effectively prevents the nut from falling off when subjected to external force or vibration, improves the stability and reliability of the connection, and prevents the bolts from loosening due to vibration in the face of a complex and changeable office environment. The top connecting plate 104 is fixedly connected to the top of the support rod 101 and the lateral support rod 102, and the top of the support unit is threadedly connected with a seat cushion 2, wherein the seat cushion 2 is located above the top connecting plate 104 and plays a main connecting role.

[0025] When in use, when the user uses the office chair with the chair legs, if the weight distribution is uneven, for example, the body leans to one side, the support rod 101 will be affected by lateral force. When the user changes from one sitting position to another, for example, from sitting upright to sitting sideways, or from sitting to standing up, these action changes may generate lateral force. When the user puts his arms on the armrests, if the arms exert force or move, lateral force on the support rod 101 will be generated. The bow-shaped design gives the lateral support rod 102 unique mechanical properties. The bow-shaped structure can disperse and withstand lateral forces from all directions, effectively enhancing the stability of the structure.
