[0034] The utility model will be further described in conjunction with the specific embodiment of the attached drawing, see Figures 1-10 Shown in:

[0035] A posture correcting cushion comprises a cushion body 1 and a backrest body 2, the cushion body 1 and the backrest body 2 are connected by at least two elastic metal sheets 3, one end of the elastic metal sheet 3 is fixed on the cushion body 1 and the other end is fixed on the backrest body 2; by applying external force, the elastic metal sheet 3 can be deformed, so that the backrest body 2 and the cushion body 1 can move relative to each other; the cushion body 1 and the backrest body 2 are provided with soft pads 9. The elastic force of the elastic metal sheet 3 is selected by the manufacturer according to the actual situation, and different elastic metal sheets can be obtained by adjusting the rigidity, material and thickness of the elastic metal sheet. As preferred, two elastic metal sheets 3 are arranged between the cushion body 1 and the backrest body 2, and multiple elastic metal sheets 3 can also be arranged, such as three or four elastic metal sheets 3.

[0036] The gap between the backrest body 2 and the cushion body 1 is provided, as shown in Figure 4 and Figure 7 The gap between the backrest body and the cushion body is L1, the backrest body 2 and the cushion body 1 move relative to each other, and the width of the gap L1 between the backrest body and the cushion body also changes. By setting the gap, the backrest body and the cushion body have a certain amount of movement, and they will not interfere with each other during movement. After setting the gap, it is necessary to consider that the gap cannot affect the user, so the gap width is greater than 1cm, and during the movement of the backrest body and the cushion body, the gap width is also not less than 0.5cm, so that the gap will not pinch the user's clothes or body. As preferred, the gap is between 1-5cm, and the specific gap width is selected by the manufacturer according to the actual situation.

[0037] As preferred, the cushion body 1 has a fixed upper support 12 and a lower support 13, and a cavity is formed between the upper support 12 and the lower support 13, the elastic metal sheet 3 is inserted into the inner cavity of the cushion body 1, and the elastic metal sheet 3 can swing in the inner cavity. The middle and / or lower end of the elastic metal sheet is hidden inside the cavity, thereby protecting the position, and the cavity also provides effective movement space for the elastic metal sheet. As shown in Figure 7 A gap L2 is provided between the skirt and the elastic metal sheet, and the skirt does not affect the deformation of the elastic metal sheet.

[0038] In the state without external force, the elastic metal sheet 3 is attached to the inner side surface of the inner cavity, and the external force is applied to the backrest body, the backrest body is turned outward, and the elastic metal sheet can be separated from the inner side surface of the inner cavity. By means of face-to-face attachment, the natural placement state of the elastic metal sheet has a leaning, and the structure will be more stable.

[0039] The seat cushion body 1 and / or the backrest body 2 are provided with a skirt on the outer side of the elastic metal sheet 3, which covers the elastic metal sheet 3. Since the elastic metal sheet can be deformed moderately, the skirt can protect the elastic metal sheet from being interfered by external components and affect the experience. Preferably, the seat cushion body and the backrest body are both provided with a skirt, and the two skirts partially overlap, and the two skirts can cover the elastic metal sheet during the relative movement of the seat cushion body and the backrest body.

[0040] The upper end of the elastic metal sheet 3 is fixed on the back of the backrest body 2, the cover 4 is fixed on the outer side of the elastic metal sheet 3 and covers the upper end of the elastic metal sheet 3, and the cover 4 extends downward to form a cover skirt 41. As shown in Figure 7 The lower end of the cover forms a cover skirt 41 which partially overlaps with the seat cushion body skirt 11 and covers the elastic metal sheet.

[0041] The seat cushion body 1 and the backrest body 2 are both provided with a mounting groove for limiting the elastic metal sheet 3, and the elastic metal sheet 3 cannot be separated from the mounting groove, as shown in Figure 9 and Figure 10 The seat cushion body mounting groove 14 and the backrest body mounting groove 21 simultaneously limit the elastic metal sheet, avoid the lateral deformation of the elastic metal sheet, and make the backrest body only move in the front-back direction relative to the seat cushion body.

[0042] The above embodiments are only preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
