[0005] The purpose of the present invention is to provide a method for manufacturing a posture-enhancing sitting position with a better user experience, which has the characteristics of short time consumption, high quality, low cost and high production capacity.

[0006] To achieve the above purpose, the present invention provides a solution: a posture-enhancing cushion comprising

[0007] Plastic housing;

[0008] Back sheet;

[0009] a first composite film, composited on the back side of the back sheet, the back sheet being bonded to the back side of the plastic shell, the first composite film being located between the back sheet and the plastic shell;

[0010] Frontal film;

[0011] The second composite film is composited on the back of the front sheet. The front sheet is formed integrally with the plastic shell by foaming a forming sponge foaming material. The second composite film is located between the front sheet and the forming sponge.

[0031] After adopting the above solution, the gain effect of the present invention is:

[0032] Compared with the prior art, the present invention adds a first and a second composite film, and composites them with the front and back sheets respectively. The seat cushion can utilize the wear-resistant, oil-resistant and highly elastic characteristics of the first and the second composite films to increase the softness and wear resistance of the seat cushion, thereby extending the service life of the seat cushion and enhancing the user experience; at the same time, the presence of the first composite film also enhances the adhesion between the back sheet and the plastic shell. Compared with the products made of spray glue in the prior art, the products in this case are not affected by the spray glue layer, and the adhesion is more reliable, which reduces the defective rate of the product and thus reduces the production cost.

[0033] In addition, the present invention adopts a foaming one-piece molding method to replace the existing spray glue bonding method. The front piece and the plastic shell are molded into one by the stickiness of the foaming material after foaming. The bonding force is much greater than the bonding force between the spray glue layer and the front piece and the plastic shell. During use, the seat cushion can be prevented from cracking, leaking and other adverse phenomena. The use of foaming one-piece molding ensures the consistency of the product while greatly reducing the spray glue process, thereby improving the production efficiency of the product, and this method can be used for automated production of products.

[0038] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] The present invention provides a posture-enhancing cushion, such as Figure 3As shown, it includes a back sheet 1, a first composite film 2, a plastic shell 3, a molded sponge 4, a second composite film 5 and a front sheet 6. The back sheet 1, the first composite film 2, the plastic shell 3, the molded sponge 4, the second composite film 5 and the front sheet 6 are stacked in sequence from bottom to top. The molded sponge 4 is foamed by a foaming material; the front sheet 6 is integrally formed with the plastic shell 3 by foaming the foaming material of the molded sponge 4; the back sheet 1 is bonded to the back of the plastic shell 3.

[0040] In order to enhance the user experience, the present invention adds a first composite film and a second composite film to increase the softness and elasticity of the seat cushion and extend the service life of the seat cushion. The first composite film 2 is composited on the front of the back sheet 1 and is located between the back sheet 1 and the plastic shell 3; the second composite film 5 is composited on the back of the front sheet 6 and is located between the molded sponge 4 and the front sheet 6; in this case, the first composite film 2 is an EVA or TPU film; the second composite film 5 is a TPU film.

[0041] At the same time, the presence of the first composite film also enhances the adhesion between the back sheet and the plastic shell. When the first composite film 2 is EVA film, the back sheet 1 is cold-pressed and fixed to the plastic shell 3 via the EVA film. When the first composite film 2 is TPU film, the back sheet 1 is integrally formed with the plastic shell 3 via the foaming material of the molded sponge 4. Compared to products bonded using spray adhesive in the prior art, these two bonding methods are more secure and unaffected by the spray adhesive layer, reducing the number of defective products and thus lowering production costs.

[0042] The above-mentioned posture-beautifying cushion can be manufactured by the following manufacturing methods.

[0043] Method 1, the specific steps are as follows:

[0044] S1, first, processing the front sheet and the back sheet, laminating the first composite film on the back side of the back sheet, and laminating the second composite film on the back side of the front sheet;

[0045] S2, secondly, adsorbing the front sheet obtained in step S1 on the top of the sponge forming mold by vacuuming;

[0046] S3, from this time, placing the plastic shell into the forming sponge mold, and then adding foaming material into the forming sponge mold for foaming, so that the front sheet and the plastic shell are integrally formed by foaming, at this time, the second composite film is located between the front sheet and the forming sponge;

[0047] S4. Finally, the back sheet obtained in step S1 is fixed to the plastic shell by cold pressing and is located on the back of the molded part obtained in step S3. At this time, the first composite film is located between the back sheet and the plastic shell, which can further enhance the adhesion between the back sheet and the molded sponge, making the back sheet and the plastic shell more tightly bonded.

[0048] Method 2: The specific steps are as follows:

[0049] S1, first, processing the front sheet and the back sheet, laminating the first composite film on the back side of the back sheet, and laminating the second composite film on the back side of the front sheet;

[0050] S2, secondly, cold-pressing the back sheet obtained in step S1, wherein the back sheet is fixed to the plastic shell by cold-pressing the first composite film, and then placed in a sponge forming mold;

[0051] S3, from this time, the front sheet obtained in step S1 is adsorbed on the top of the sponge forming mold by vacuuming;

[0052] S4, finally, adding foaming material into the forming sponge mold for foaming, so that the front sheet, the back sheet and the plastic shell obtained in step S2 are integrally formed.

[0053] Method 3, the specific steps are as follows:

[0054] S1, first, processing the front sheet and the back sheet, laminating the first composite film on the back side of the back sheet, and laminating the second composite film on the back side of the front sheet;

[0055] S2, secondly, adsorbing the back sheet obtained in step S1 under the forming sponge mold by vacuuming;

[0056] S3, from this time, the front sheet obtained in step S1 is adsorbed on the top of the sponge forming mold by vacuuming;

[0057] S4, finally, placing the plastic shell in the forming sponge mold, and pouring the forming sponge foaming material into it, so that the front sheet, the back sheet and the plastic shell are integrally formed by foaming.

[0058] The present invention adopts a foaming one-piece molding method to replace the existing spray bonding method. The front piece and the plastic shell are molded into one piece through the stickiness of the foaming material after foaming. Compared with the spray bonding method of the prior art, the foaming one-piece molding has stronger adhesion, better effect, and faster speed, which can better ensure product consistency, reduce the production of defective products, and reduce production costs. In addition, since the seat cushion is integrally molded, its adhesion is much greater than the adhesion between the spray glue layer and the front piece and the plastic shell. During use, the seat cushion can be prevented from cracking, leaking and other adverse phenomena, and there is no irritating glue smell.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. Any equivalent changes made based on the key design of this case shall fall within the scope of protection of this case.
