[0032] The ring-shaped fabric 2 can be tightened under the action of external force, so that the sheath 2 is tightly attached to the soft cushion 211, thereby switching the soft cushion assembly from a relaxed state to a tight support state.

[0033] Further, the soft cushion 211 in the embodiment is a shaped cotton filled in the sheath 21; the shaped cotton has good resilience and can still maintain the original shape after being stressed for many times, avoiding collapse or deformation of the soft cushion assembly after being used for many times.

[0034] Further, in order to ensure that the ring-shaped fabric 2 and the sheath 21 are firmly connected, the outer edge of the sheath 21 and the inner side edge of the ring-shaped fabric 2 are connected by sewing.

[0035] Further, a chair back frame assembly structure is provided, which comprises a back support frame and the flexible support assembly; the back support frame comprises a ring-shaped frame body 1, the back support frame is usually a plastic part integrally formed by relying on a mold, and the frame body 1 structure is similar to the screen frame structure usually used for setting screen cloth; the ring-shaped fabric 2 is matched with the frame body 1; in the chair back frame assembly structure, the flexible support assembly corresponds to a flexible support module, the ring-shaped fabric 2 corresponds to a connecting carrier between the soft cushion assembly and the frame body 1, the ring-shaped fabric 2 covers the front side of the frame body 1, and the ring-shaped fabric 2 is tightened and fixed on the frame body 1, so that the soft cushion assembly is tightly set on the frame body 1 and kept in place, which makes the soft cushion assembly indirectly set on the frame body 1 by relying on the ring-shaped fabric 2 as a carrier, so that the soft cushion assembly can also form a stable and comfortable support feeling on the back support frame without relying on the front of the plate-shaped back support plate, improves the universality of the back support frame, reduces the production cost of the seat, and improves the assembly efficiency of the seat.

[0036] Further, the soft cushion assembly can provide comfortable and flexible support in the middle of the frame body 1, but the soft cushion assembly does not cover the front side of the frame body 1, so the support of the frame body 1 position is relatively hard. In order to improve the sitting comfort, a flexible pad 3 matching the frame body 1 is arranged between the annular fabric 2 and the frame body 1. The flexible pad 3 can be a rubber pad or a plastic pad with elasticity. When the flexible pad 3 is installed, the adhesive glue is evenly applied on the front side of the frame body 1, and the flexible pad 3 is covered on the adhesive glue, so that the flexible pad 3 is glued to the position of the frame body 1. The flexible pad 3 can give the position of the frame body 1 flexible support, avoid the frame body 1 to produce relatively hard support feeling to the sitter, and the flexible pad 3 is also covered by the annular fabric 2, so it will not affect the appearance of the seat.
