The backrest leans backward above the point, making an angle of 6 ~ 1 2 with the vertical plane (Figure1,β). The front projection near the back is rounded (figure 1), and the upper and lower edges are machined into circular arcs. The curvature radius of the concave surface of the backrest (Figure 2, γ) exceeds 500mm. There is a gap between the lower edge of the backrest and the rear edge of the seat surface.
Note: the backrest point is the most protruding point of the backrest forward on the center line of the chair. It is the basis of calculating the height of the upper and lower edges of the backrest, so that the backrest is supported at the waist back position under the shoulder angle.
