[0019] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0020] like Figure 1-Figure 3 As shown, the structurally stable seat back cushion provided by the present embodiment includes a thin curved plate 1, a sponge 2 is arranged on the outer side of the thin curved plate 1, a fabric 3 is arranged on the outer side of the sponge 2, the fabric 3 is coated on the thin curved plate 1, and a thick curved plate 4 is arranged on the back side of the thin curved plate 1. The thin curved plate 1 and the thick curved plate 4 are connected by bolts. The coating process can make the plate and the fabric 3 very tightly connected, but when the thick curved plate 4 is connected to other parts of the seat, it is necessary to reserve installation space at the edge, so the sponge 2 and the fabric 3 cannot be directly coated on it, so the thin curved plate 1 is introduced, the sponge 2 and the fabric 3 are coated on the thin curved plate 1, and then the thin curved plate 1 and the thick curved plate 4 are connected by bolts, so as to achieve the purpose of stabilizing the overall structure of the seat back cushion.

[0021] In this embodiment, if Figure 2As shown, an L-shaped plate 5 extends downward from the edge of the thin curved plate 1 to facilitate the covering of the fabric 3, so that a cavity 6 is formed between the thin curved plate 1 and the thick curved plate 4 to accommodate the four-claw nails 8, the positioning slots 10 and the positioning inserts 11.

[0022] In this embodiment, if Figure 1 As shown, the thin bent plate 1 is provided with a plurality of through holes 7, and four-claw nails 8 are provided in the through holes 7. The thick bent plate 4 is provided with a plurality of threaded holes 9 at positions corresponding to the through holes 7. Bolts are inserted from the back side of the thick bent plate 4 and gradually screwed into the threaded holes 9 and the four-claw nails 8 to connect the thin bent plate 1 and the thick bent plate 4.

[0023] In this embodiment, if Figure 1 As shown, four through holes 7 are provided, and the four through holes 7 are evenly distributed on the thin bent plate 1, so the connection effect is better.

[0024] In this embodiment, if Figure 1 and Figure 2 As shown, a positioning slot 10 is provided on the front of the thick bent plate 4, and a positioning insert 11 used in conjunction with the positioning slot 10 is provided on the back of the thin bent plate 1. During assembly, after the positioning insert 11 is inserted into the positioning slot 10, the positions of the four-claw nails 8 and the threaded holes 9 will correspond, making installation convenient.

[0025] In this embodiment, if Figure 1 As shown, two positioning slots 10 are provided, and the two positioning slots 10 are evenly distributed on the thick bent plate 4, so the positioning effect is better.

[0026] In summary, in this embodiment, by adding a thin curved plate 1, the sponge 2 and the fabric 3 are fastened to the thin curved plate 1 by a coating process, so as to achieve a close fit between the thin curved plate 1, the sponge 2 and the fabric 3. By means of bolt connection, the thin curved plate 1 and the thick curved plate 4 are tightly combined, the gap between the two is eliminated, the stability of the overall structure of the seat back cushion is ensured, the possibility of falling off is effectively avoided, and the aesthetic and practical functions of the seat back cushion are taken into account; through the positioning slot 10 and the positioning insert 11, the thin curved plate 1 and the thick curved plate 4 can be quickly and accurately aligned with the positions of the four-claw nail 8 and the threaded hole 9 during the assembly process. Subsequently, the installation can be completed by inserting and tightening the bolts, which greatly improves the convenience and efficiency of assembly.

[0027] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
