New description: [New technical field] [0001] This creation is about a chair back structure of a chair, especially a kind of softness to conform to the curve of the back when the human body is placed, so that the ride is abutted More comfortable chair back structure innovative design. [Prior Art 3 [0002] According to the chair in the market, in order to provide comfort during riding, a seat back is usually provided at the rear end of the seat for riding, so that the occupant can stick the back when riding the chair. Relying on the back of the chair, the back is under the support of the back of the chair to reduce the weight of the human body to the human body and to be more comfortable. [〇〇〇3] However, the material usually used for the back of the general plastic chair is relatively hard' and the lumbar support is not integrated, so that it can not produce a conforming effect with the back of the human body, and it is not ergonomic. The effect of effectively controlling the back of the human body is achieved; in addition, the backs of the plastic chairs are considered to have structural strength, so no piercings are provided on the backs of the plastic chairs, so when the back of the human body is placed against the chair When backing, the back of the human body and the back of the chair are in a state of being attached and affixed, and there is no ventilation effect, so the back of the occupant is easily sultry and uncomfortable. Therefore, if a chair back that is both soft and supportive and has a ventilating effect is provided, the occupant can be more comfortable in riding, and the presenter created this creation in view of this. [New content] The main purpose of this creation is to provide ___ with a chair back structure, which has good materials and recordings, and can be used with the back of the human body. Page 3 of 11 Form No. A0101 [ 0005] M416404 [0007] [0007] The line is deformed to produce a good conformity state with the back of the human body, and has a good ventilation and ventilation effect. The main purpose of the above creation is achieved by the following specific means: A seat back structure of a chair is provided with a plurality of perforations on the back of a chair made of plastic composite material, each of which has a small intermediate aperture and two The shape of the end aperture is large, and the adjacent perforations between the adjacent sides are arranged in a staggered manner. The seat back itself is curved from the two sides toward the middle in a first direction, and the lower part of the back of the seat back to the lower end is The two-direction curved protrusion forms a lumbar support. Accordingly, the back of the chair is made of a plastic composite material, and has a plurality of perforations having a small intermediate hole diameter and a large aperture at both ends, and the adjacent side of each side of the side is arranged in a staggered manner. The back of the chair has the effect of soft deformation and support, and can further conform to the curve when the back of the human body is in contact with the ergonomics, so as to achieve a more comfortable and ventilating effect when riding. [0010] [Embodiment] For a more complete and clear disclosure of the technical means, creative purpose and achievement of the present invention, the following is a detailed description, and please refer to the disclosed drawings and component symbols. . Please refer to the first to third figures, which are the vertical appearance and side view and top view of the back structure of the creation. The back of the creation (1) is made of plastic composite material and has flexibility. The back of the seat (1) itself is curved from the sides to the middle in the first direction (D 1 ), and the form is edited. No. A0101 Page 4 of 11 M416404 The lower part of the back of the seat back (l) to the lower end is arranged in a curved direction in the second direction (D2) opposite to the first direction (D1), and is formed accordingly. The lumbar support portion (2); further, the seat back (1) is provided with a plurality of perforations (11) [hereinafter referred to as the fourth figure], each of the perforations (11) has a small intermediate aperture and a large aperture at both ends. The respective perforations (11) of the shape and adjacent to each other are arranged in a staggered manner. _] When the back of the human body rests against the back of the chair (1) and is the back of the seat (1)
