As a further improvement of the above technical solution, the support plate includes a base plate and a three-dimensional fabric layer, and the three-dimensional fabric layer is disposed on a front sidewall of the base plate.
As a further improvement of the technical scheme, the supporting plate is arranged at the rear side of the fabric, the lower part of the supporting plate is abutted to the fabric, the upper part of the supporting plate is in a backward convex curve shape, and a gap is reserved between the upper part of the supporting plate and the fabric.
As a further improvement of the technical scheme, the longitudinal section of the supporting plate is S-shaped.
As a further improvement of the technical scheme, the supporting plate and the chair back frame are integrally formed.
As a further improvement of the technical scheme, the width of the supporting plate is one sixth to one third of the width of the fabric.
As a further improvement of the technical scheme, the supporting plate is made of plastic, wood-plastic composite material, wood or metal.
The beneficial effects of the utility model are as follows: according to the utility model, the supporting plate is arranged in the middle of the chair back frame, the lower part of the supporting plate is in a front convex curve shape, and after the waist is pressed down, the supporting points of the waist move forwards and backwards along with the waist, so that the waist can be supported in real time, the lumbar stress can be relieved, and the chair is suitable for sedentary;
and moreover, the supporting plate is strip-shaped and longitudinally arranged at the rear side of the fabric, so that the modern seat has the design characteristics of a traditional Ming-style chair in China, and the design sense of the seat is improved.
