New description: [New technical field] ^This author is about the improvement of a chair back structure, mainly using a front frame of a chair back and a frame behind the chair and a group I is obtained from the front face of the front frame of the chair f A mesh cloth is set up to form a mesh seat back, and a relatively suitable clamping jaw groove is formed along the frame edge of the front and rear frames of the back of the chair, and the quick group negotiation function of the mesh cloth can be obtained, and at the same time, The ergonomic design of the top waist panel of the lower inner edge of the front frame of the back of the chair is the best comfort cushion for the human waist. [Previous technique] Press, the traditional chair back In design, it is usually designed with solid design, which causes j human body to lie on the valley. It is easy to be sultry due to poor ventilation, which seriously affects the comfort of lying. In order to solve such problems, there is a question of mesh back. The back of the chair and the opening of the mesh provide a good ventilation and ventilation effect, so that it does not have too much sultry problem when lying down, so that better lying comfort can be obtained. The design of the back of the chair, generally multi-series adopts the set of sets, will The cloth is made into a back cover type, and then set on the back frame of the chair. Finally, the mesh back cover and the back frame are fixed by locking or snapping, or the frame is surrounded by the rear edge of the back frame. A stagnation trough is arranged to open the net cloth: the rear edge of the back frame of the chair, and then embedded in a groove of the back frame by a frame strip, and the second-shaped cloth plaque is located in the embedding groove to obtain the net The position of the cloth and the back frame is different. The position of the mesh is maintained. The way the mesh is laid is not only ugly in appearance, but also the cow's solidity is not good. It is not an ideal design. M324454 <Upper, in this type of mesh chair back, because the back of the chair is hollowed out, although it can give better ventilation and ventilation, it lacks the branch to the waist. The effect 'to solve this problem - some mesh chairs f will be added to the lower part of the back of the chair - the top waist plate, so as to form a proper support for the waist of the human body to obtain better sitting comfort; The system is designed to achieve more support than the four-frame system. 'But the material is not talkative', causing it to have a (four) sexual touch on the waist of the human body, but it is easy to cause discomfort in the waist. It is called the perfect designer from the south. [New content] Many problems existed in the structural design of the mesh chair back = the car creator specializes in research and improvement, based on his experience and technology in related fields, and then researches and creates the improved structure of the creation, namely: := Γ 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由 经由The comfort of the pad. The other purpose of the design is to design the structure through the structure of the structure, and use the wide front frame and the back frame of a chair to hold the mesh, which can enhance the appearance and enhance the appearance. The stability of the mesh is set. One is for the purpose of the front. The original design is made up of a net mesh and a frame behind the chair. The chair is the back frame of the chair. There is a relative deed along its frame The clip of the embedded card 掣θ# is laid on the front edge of the front frame of the back of the chair, and then pulled over the front and rear frames of the back of the chair-M324454, and the clamping groove is used for fastening and fixing. The inner edge of the lower frame of the front frame of the back of the frame is further integrally formed with a top waist plate which can support the waist of the human body, and the top waist plate is obtained by a curved connecting piece and a front frame of the back of the chair to obtain a single side connection below, thereby enabling the top waist plate to be Obeying the ergonomic curve to obtain the best relationship between the waist and the waist, and at the same time, the arc connecting piece is provided with a reinforcing rib groove, and the connecting piece and the top waist plate are provided with an appropriate elastic buffering margin, thereby enhancing It is comfortable for the waist of the human body. [Embodiment], Qian Qian (4) structure (four), technical means and efficacy to achieve 'in conjunction with the diagram is further illustrated in the following examples: Please refer to the structural decomposition diagram of Figures 1 and 2, the structure of Figure 3 The combination diagram and the structural relationship diagrams of Figures 4 to 6 are the best examples of the creation. As shown in the figure, the mesh back of the creation is designed on the back of the chair. Frame (1〇), a chair back frame (20), and - mesh (3Q), - cover (4 ()) and other components | made, where: the front of the chair back (1 〇 ), the ergonomically designed wide-framed body, the inner edge of the frame is inwardly curved, and the outer edge of the outer frame is fixed along the frame at the trailing edge of the frame (4). The clamping jaws (11) are further provided with a predetermined number of screw holes (12) on the inner circumference of the back surface of the frame body, and the bolts (1) are used to lock the front and rear frames of the seat back (丄〇) (2) 〇), an arc-shaped connecting piece (13) is extended on the inner edge of the frame at the lower part of the frame body, and a top-size waist plate of an appropriate size is extended on the top end of the curved connecting piece (13). 'Making the top waist plate (15) obtained by the connecting piece (work 3) with the seat back 7
