The lumbar and back support component is a long fishbone-shaped structure, including a longitudinal main support plate and ribs arranged at intervals on the main support plate; the lumbar and back support component is elastic as a whole, the main support plate can undergo elastic bending deformation in the vertical direction, and the ribs can undergo elastic deformation in the left and right directions; a first rotation joint is formed at the part where the main support plate is connected to the ribs, and a second rotation joint is formed at the part where the main support plate is not connected to the ribs.

[0004] For another example, the patent document with publication number CN217447154U discloses an ergonomic chair back assembly, including a back support body, a support spine and a support; the back support body is an integrated structure and is elastic, and the back support body includes a plurality of longitudinally arranged strip support blades; and a curved deformation portion with a hollow structure is provided in the middle position of each strip support blade; longitudinal connecting ribs are also provided on both sides of the rear end of the back support body; the support spine is a rigid structure, and the support spine is configured to be connected to the connecting ribs.

[0005] For another example, the patent document with publication number CN218304116U discloses an adaptive elastic chair back, including a fixing frame and a chair back body; the chair back body includes a lumbar support portion and a plurality of elastic connection portions, the lumbar support portion is fixedly connected to the fixing frame, the lumbar support portion is provided with a plurality of cross bars and a plurality of grooves arranged at staggered intervals along the vertical direction, a mounting portion is provided between two adjacent cross bars, and the mounting portion is located on both sides of the groove, the thickness of the mounting portion is less than the thickness of the cross bar, and the elastic connection portion is coated on the outer side of the mounting portion.

[0006] In the above technology, the chair back uses openings to control elastic deformation, the support is average, and the support parts are formed by a combination of multiple structures, which makes processing difficult.

[0007] Therefore, a kind of conformable supporting chair back is proposed to solve the above-mentioned technical problems. Utility Model Content

[0008] In order to solve the above technical problems, the purpose of the utility model is to provide a shape-adapting support chair back, which has the advantages of simple structure, good support and simple processing.

[0010] As a further improvement of the above technical solution, the support plate is an integral carbon fiber plate, and the support portion 3 is made of leather or elastic fabric.

[0011] As a further improvement of the above technical solution, the middle part of the frame bulges toward one side to form a waist support.

[0012] As a further improvement of the above technical solution, a groove is provided outside the frame, and the edge of the fabric extends and is pressed into the groove.

[0013] As a further improvement of the above technical solution, the bottom and the front parts of both sides of the frame are provided with installation grooves, and reinforcing ribs are fixedly installed in the installation grooves.

[0014] The beneficial effects of the utility model are as follows: the carbon fiber board is used as the support board, so the support effect is good, and at the same time, through holes are formed on the support part, so that the support board can be better fitted.
