  • Patent number: 10561247
    Abstract: A chair back structure includes a flexible sheet, the flexible sheet mounted on a support plate so as to adjust a curvature of a chair back by changing a curvature between two ends of the flexible sheet. A fixing segment of the flexible sheet is connected with an end of the support plate. The support plate includes two tilted abutting tabs configured to abut against with a moving segment of the flexible sheet in a sliding path, such that when the moving segment is operated to change the curvature of the flexible sheet, the moving segment slides along the two tilted abutting tabs forward or backward so as to produce a displacement, thus enhancing a bending deformation of the chair back.
