[0007] As a further improvement to the above technical solution, the upper part of the support plate is attached to the back plate, and a gap is left between the lower part of the support plate and the back plate; the gap between the lower part of the support plate and the back plate gradually increases from top to bottom.

[0008] As a further improvement to the above technical solution, the first connecting part includes a first connecting hole, and the second connecting part includes a second connecting hole, wherein the first connecting hole and the second connecting hole are detachably connected by screws.

[0009] As a further improvement to the above technical solution, the lower end of the support plate is provided with a first horizontal portion, and the lower end of the back plate is provided with a second horizontal portion, with the first horizontal portion fixedly connected below the second horizontal portion.

[0010] As a further improvement to the above technical solution, a positioning hole is provided on the upper side of the first transverse portion, and a positioning post is provided on the lower side of the second transverse portion, wherein the positioning post is inserted into the positioning hole.

[0011] As a further improvement to the above technical solution, a base is fixedly connected to the lower part of the second horizontal portion, and a mounting cavity is formed between the base and the second horizontal portion. A first opening is provided on the rear top of the mounting cavity, and the first horizontal portion is installed in the mounting cavity through the first opening.

[0012] An ergonomic chair includes a seat and a backrest assembly as described above. A second opening is provided on the front side of the mounting cavity, and a connecting block is provided on the rear side of the seat. The connecting block is inserted into the mounting cavity through the second opening, and the connecting block is detachably connected to the mounting cavity.

[0013] As a further improvement to the above technical solution, the upper side of the connecting block is provided with a recess that matches the first transverse portion, and the first transverse portion cooperates with the recess.

[0014] The beneficial effects of this utility model are: by providing a first connecting part on the support plate and a second connecting part on the back plate, and by detachably connecting the first connecting part and the second connecting part, the support plate can be removed from the back plate, which facilitates transportation.

[0025] Reference Figures 1 to 5 A backrest assembly includes a back panel 2 and a support plate 1. The support plate 1 abuts against the rear side of the back panel 2. The support plate 1 has a first connecting portion, and the back panel 2 has a second connecting portion adapted to the first connecting portion. The first connecting portion and the second connecting portion are detachably connected. The engagement method between the first connecting portion and the second connecting portion can be, but is not limited to, a snap-fit ​​connection and a bolt connection. The detachable connection between the first connecting portion and the second connecting portion allows the support plate 1 to be removed from the back panel 2, reducing the transport volume and facilitating transportation.

[0026] In a preferred embodiment, the upper part of the support plate 1 is fitted to the back plate 2, and a gap is left between the lower part of the support plate 1 and the back plate 2; the gap between the lower part of the support plate 1 and the back plate 2 gradually increases from top to bottom, the upper part of the support plate 1 better supports the thoracic spine, and the lower part of the support plate 1 provides considerable deformation space for the lumbar spine, thus better supporting the lumbar spine.

[0027] In some embodiments, the first connecting part includes a first connecting hole 11, which is disposed on the upper half of the support plate 1, and a nut is pre-embedded in the first connecting hole 11. The second connecting part includes a second connecting hole 21, which is disposed at a corresponding position on the back plate 2. The first connecting hole 11 and the second connecting hole 21 are detachably connected by screws.

[0028] In a preferred embodiment, the lower end of the support plate 1 is provided with a first horizontal portion 12, and the lower end of the back plate 2 is provided with a second horizontal portion 22. The first horizontal portion 12 is fixedly connected to the lower part of the second horizontal portion 22, so that the bottom assembly structure of the back plate 2 and the support plate 1 is stable.

[0029] In a preferred embodiment, the upper side of the first transverse portion 12 is provided with a positioning hole 121, and the lower side of the second transverse portion 22 is provided with a positioning post 221. The positioning post 221 is inserted into the positioning hole 121. By providing the positioning post 221, positioning is facilitated and assembly stability is further enhanced.

[0030] In some embodiments, a base 23 is fixedly connected to the lower part of the second transverse portion 22, and a mounting cavity is formed between the base 23 and the second transverse portion 22. A first opening 24 is provided at the rear top of the mounting cavity, and the first transverse portion 12 is mounted in the mounting cavity through the first opening 24.

[0031] An ergonomic chair includes a seat 3 and a backrest assembly as described above. A second opening 25 is provided on the front side of the mounting cavity, and a connecting block 31 is provided on the rear side of the seat 3. The connecting block 31 is detachably snapped into the mounting cavity through the second opening 25. A recess 311 adapted to the first transverse portion 12 is provided on the upper side of the connecting block 31. The first transverse portion 12 is pressed into the recess 311, thereby making the seat 3, backrest 2 and support plate 1 detachable, further facilitating transportation.
