It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the present invention.

[0024] In the description of the present invention, the meaning of "several" is one or more, the meaning of "multiple" is two or more, "greater than", "less than", "exceeding", etc. are understood as not including the recited number, and "above", "below", "within", etc. are understood as including the recited number. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0026] Refer to Figure 1, A spinal support member, comprising: a first elastic unit 22, the cross-section of the first elastic unit 22 being a polygon with an opening, the first elastic unit 22 having a first end 221 and a second end 222 arranged at intervals; the width of the first elastic unit 22 is 1-20 cm, the height of the first elastic unit 22 is 1-30 cm, and the distance between the first end 221 and the second end 222 is 0.5-25 cm. In use, the waist is supported by the first elastic unit 22. Since the first elastic unit 22 has elasticity and the ends can move, it can undergo offset deformation along the lumbar spine direction during support, so as to gently support the lumbar spine; and different widths can be selected according to the user's lumbar spine to effectively support the user's lumbar spine.

[0027] As a preferred embodiment, it further includes a second elastic unit 23. The second elastic unit 23 includes a third end 231 and a fourth end 232 arranged at intervals. The first elastic unit 22 and the second elastic unit 23 are arranged vertically; the second end 222 is connected to the third end 231. An installation portion 21 is provided at the connection between the second end 222 and the third end 231. The first end 221 is bent inward, and the fourth end 232 is bent inward. The first end 221 and the fourth end 232 are used to abut against the support plate 1.

[0028] As a preferred embodiment, the first elastic unit 22 is integrally formed.

[0029] As a preferred embodiment, a groove 223 extending in the front-rear direction is provided on the side wall of the first elastic unit 22. After the groove 223 is provided, the elasticity of the first elastic unit 22 is better.

[0030] As a preferred embodiment, the groove 223 is provided on the inner wall of the first elastic unit 22. The function of the groove 223 is to control the deformation direction of the first elastic unit 22 when it is stressed and deformed. Since the groove 223 is provided on the inner wall, when the first elastic unit 22 deforms, the inner wall of the groove 223 is squeezed and shrinks, and the side wall of the first elastic unit will arch outwards.

[0031] As a preferred embodiment, the first elastic unit 22 further includes a connecting rib 24, and the connecting rib 24 is used to connect the first end 221 and the second end 222 to prevent the deformation of the first elastic unit 22 from being too large.

[0032] Refer to Figure 2-3 , A chair back, comprising a spinal support member, and further comprising a main body 11, a fabric 3 installed on the main body 11, and a support plate 1. The spinal support member is installed in the middle of the front side wall of the support plate 1 and is used to support the lumbar spine, and the fabric 3 is arranged on the front side of the spinal support member.

[0033] As a preferred embodiment, it further includes a lumbar cushion 5 which is adjustably mounted on the support plate 1 in the vertical direction, and the first elastic unit 22 is located inside the lumbar cushion 5. It can support the lumbar spine while supporting the waist, further improving the use comfort.

[0034] As a preferred embodiment, a load-bearing plate 4 is provided on the fabric 3. The load-bearing plate 4 is made of plastic and is arranged on the front side of the first elastic unit 22.

[0035] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
