[0023] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0024] As Figs. 1-2 indicated, the multi-layer support structure cushion comprises:

[0025] The cushion body 10 is provided with a Lycra cloth layer 11, a TPU material layer 12, a gel layer 13, a first memory cotton layer 14, a second memory cotton layer 15 and a TPU anti-skid fabric layer 16 from top to bottom in sequence.

[0026] Among them, the Lycra cloth layer 11 is a surface layer and has high elastic and breathable properties; the TPU anti-skid fabric layer 16 is a bottom layer, and the outer surface thereof is provided with an anti-skid structure 17, the anti-skid structure 17 is provided with regular linear textures 18, the linear textures 18 are composed of multiple groups of linear protrusions arranged in parallel, and the arrangement directions of the linear protrusions in each group change at an angle.

[0027] The Lycra cloth layer 11 as the surface layer of the cushion adopts Lycra cloth with high elastic and breathable properties, so that the surface has good elasticity and breathability, and the comfort is effectively increased, and the stuffiness is avoided during use.

[0028] Lycra cloth is a synthetic fiber material with high elasticity, which is usually composed of polyester fiber and spandex. Spandex is one of the main components of Lycra cloth, which makes the fabric have excellent elasticity and can quickly restore to its original shape, and adapt to shape changes. Therefore, Lycra cloth is widely used in many applications, especially in sports clothes, swimwear and furniture and cushion materials with high comfort requirements.

[0029] Lycra cloth has the following advantages:

[0030] High elasticity: Lycra cloth can be stretched to 5 times of its original length, and has excellent recovery.

[0031] Breathability: Lycra cloth has good breathability, which makes it suitable for use as a close-fitting fabric or cushion surface material, keeping dry and comfortable.

[0032] Soft and comfortable: Lycra cloth has a soft touch and is comfortable to wear or touch, and is suitable for long-term use.

[0033] Durability: This fabric not only has good tensile strength, but also can withstand long-term use without easy deformation.

[0034] Gloss: Lycra cloth has a certain gloss, and the appearance is usually more bright, suitable for high-grade fabrics.

[0035] TPU material layer 12 is below the Lycra cloth layer 11, which has moderate hardness, provides certain supporting force, and plays a protective role for other layer materials.

[0036] TPU (Thermoplastic Polyurethane) is a high-performance polymer material with the characteristics of both plastic and rubber. In the design of the cushion, the TPU material layer provides strength and support, increasing the durability.

[0037] In the utility model, the TPU material has the following advantages:

[0038] 1. TPU material has high elasticity, can withstand large deformation without easy breakage, showing similar elasticity to rubber, but more wear-resistant and durable than traditional rubber.

[0039] 2. TPU material has excellent wear resistance, which can prolong the service life of the product. It is widely used in shoe soles, cushions and automobile accessories.

[0040] 3. TPU material is a thermoplastic material, which can be processed by injection molding, extrusion, hot pressing and other methods, with good processing performance, easy to manufacture complex shape and structure. Compared with other plastic materials, TPU is usually more environmentally friendly, does not contain harmful substances, and is relatively easy to recycle.

[0041] Gel layer 13 is below the TPU material layer, which can effectively relieve external pressure and improve the comfort of the cushion, and has good resilience, which helps the long-term use of the cushion.

[0042] Gel layer 13 is usually made of gel material with viscoelasticity, which is widely used in medical, comfortable cushion, insole and other fields. Gel material can uniformly disperse and relieve external pressure, especially suitable for parts that need to bear pressure for a long time. In the cushion, the gel layer can reduce the pressure on the hips and back, and improve the comfort of the cushion. Gel material provides soft support, so that users can effectively relieve fatigue when sitting on the cushion for a long time. It can adapt to the changes in body contour, providing a more comfortable sitting feeling for users.

[0043] The gel layer can deform under external force, and when the pressure is removed, the gel will quickly return to its original shape, which allows the gel layer to maintain its shape over long periods of use and avoid creating long-term indentations. The gel material has good air permeability, which can help maintain a comfortable temperature and reduce overheating caused by prolonged contact.

[0044] In this embodiment, the gel layer optionally adds an antibacterial agent to prevent the accumulation of bacteria or the production of odors during use.

[0045] The gel layer is commonly used in:

[0046] Car seat cushions: During driving, a seat cushion with gel can better relieve fatigue, especially during long drives.

[0047] Medical seat cushions: Gel layers are widely used in medical and elderly care seat cushions, providing functions such as relieving pressure and reducing sciatica pain.

[0048] Office seat cushions: In an office environment, the gel layer can effectively relieve the waist and hip pressure caused by long periods of sitting, increasing comfort.

[0049] In this embodiment, further, the first memory foam layer 14 has a thickness of 10 mm and is made of high-density memory foam material, which can effectively adjust to the pressure points of the human body and provide excellent support. The second memory foam layer 15 is located below the first memory foam layer 14 and also has a thickness of 10 mm, using low-density memory foam material, mainly to increase the softness of the seat cushion and further improve the comfort of the seat cushion.

[0050] Memory foam, also known as temperature-sensitive foam or slow-rebound foam, is a high-density polyurethane foam material. Its main features include:

[0051] 1. The most notable feature of memory foam is its temperature-sensitive property. It can change shape according to changes in body temperature and pressure. When the human body comes into contact with memory foam, the material will become soft, and as the temperature rises, the memory foam becomes even softer, better adapting to the contours of the human body.

[0052] 2. Memory foam has a slow rebound speed, and when external force is removed, it can slowly return to its original shape. Its slow rebound property helps it fully adapt to the shape of the human body when in contact, providing more uniform support. When the user leaves, the memory foam gradually returns to its original shape.

[0053] 3. Memory foam can disperse body pressure and avoid creating pressure points. In this utility model, memory foam can reduce pressure on the hips and back, avoiding discomfort or pain caused by long periods of sitting. For users who sit for long periods, memory foam can effectively reduce fatigue and increase comfort.

[0054] 4. Memory foam is relatively soft, but it can still provide sufficient support, especially high-density memory foam. It can adjust the support force according to the weight and pressure distribution of the body, effectively supporting different parts of the body. High-density memory foam is usually used in places that require stronger support, such as the core layer of a seat cushion.

[0055] 5. Memory foam material has good durability, and memory foam can still maintain good shape even after long-term use.

[0056] The TPU anti-slip fabric layer 16 is the bottom layer of the seat cushion main body 10, has anti-slip performance, and the outer surface is provided with an anti-slip structure 17.

[0057] More specifically, the anti-slip structure 17 is provided with regular linear textures 18, which are composed of multiple groups of parallel straight protrusions. The arrangement direction of each group of straight protrusions changes in angle and intersects with each other, forming an "S" pattern in the center area of the outer surface of the TPU anti-slip fabric layer 16, further enhancing the anti-slip performance of the seat cushion and preventing the seat cushion from sliding during use.

[0058] Preferably, the thickness of the gel layer 13 is set to 5-10mm.

[0059] The thickness of the gel layer 13 is designed to allow the gel to effectively disperse the pressure on the seat cushion during use, providing additional comfort and relief.

[0060] Preferably, the thickness of the TPU material layer 12 is set to 0.5-1mm.

[0061] The TPU material layer 12 serves as an intermediate support layer and has durable and wear-resistant properties. Specifically, the TPU material layer 12 can provide sufficient strength and flexibility to protect the underlying memory foam and gel layer from deformation. The thinness of the TPU material layer 12 allows the overall seat cushion to maintain a relatively light weight, making it suitable for long-term use.

[0062] Preferably, the thickness of the first memory foam layer 14 and the second memory foam layer 15 is set to 10mm,

[0063] Among them, the first memory foam layer 14 is high-density memory foam, and the second memory foam layer 15 is low-density memory foam.

[0064] The first memory foam layer 14 and the second memory foam layer 15 can provide better support and comfort to the seat cushion. The high-density memory foam layer helps to support the structure of the seat cushion, and the low-density memory foam layer provides more comfort and softness. The combination of the two can ensure that the seat cushion can maintain better support and comfort, making it suitable for long-term use of the seat cushion.

[0065] Preferably, the inner surface of the TPU anti-skid fabric layer 16, which is in contact with the second memory cotton layer 15, is provided with a plurality of convex structures.

[0066] Specifically, the convex structures are formed by a plurality of small protrusions, which can increase the friction between the second memory cotton layer 15 and the TPU anti-skid fabric layer 16, prevent sliding between the two layers, and ensure the stability of the cushion during use. The convex structures are evenly distributed on the inner surface and arranged in a regular pattern, which provides better stability without affecting the comfort. Further, the design of the convex structures also helps to improve air circulation and enhance air permeability during use of the cushion, reducing the problem of heat accumulation during long-term use of the cushion.

[0067] Preferably, the cushion body 10 is provided with a sealing strip 19 around the periphery, and the sealing strip 19 is fixed by thread sewing.

[0068] The sealing strip 19 enhances the edge structure of the cushion, improves the durability of the cushion, and also plays a role in visual modification in the overall design.

[0069] Preferably, the sealing strip 19 connects the Lycra cloth layer 11 and the TPU anti-skid fabric layer 16 by thread sewing, forming the edge structure of the cushion body.

[0070] Specifically, the thread sewing adopts a double-needle flat sewing process to ensure firm and smooth connection. The sealing strip 19 avoids direct exposure of the Lycra cloth layer 11 and the TPU anti-skid fabric layer 16 during connection, improving the overall aesthetics and durability of the cushion.

[0071] Preferably, the overall shape of the cushion body 10 is circular.

[0072] The smooth edges of the cushion body 10 without sharp corners make the cushion suitable for various types of seats and provide uniform support and comfortable seating for the user.

[0073] The gel layer in the utility model is formed by the following method: a layer of TPU material is compounded with the fabric to form a composite fabric; the composite fabric is cut, and the cut composite fabric is placed in a mold; the composite fabric in the mold is subjected to vacuumizing treatment, and liquid gel is injected; the composite fabric after injection of liquid gel is subjected to solidification treatment to form a gel layer. After the gel solidifies, an integrated structure is formed, thereby effectively preventing air leakage and gel leakage problems.

[0074] In summary, the multi-layer support structure cushion in the utility model optimizes the comfort, durability and anti-skid performance of the cushion through design and material selection. The high elasticity and breathability provided by the Lycra cloth layer, the support and protection of the TPU material layer, the pressure relief effect of the gel layer, and the combination of the support and comfort of the first and second memory cotton layers ensure that the cushion can provide a comfortable sitting experience in different use scenarios. At the same time, the design of the TPU anti-skid fabric layer enhances the anti-skid performance and prevents the cushion from shifting during use. The edge strip and the circular design of the cushion make the whole more stable.

[0075] The working principle of the multi-layer support structure cushion is that the multi-layer support structure cushion is combined by multiple material layers with different functions, providing excellent comfort, support and anti-skid performance, and effectively dispersing pressure and maintaining stability during use.

[0076] Lycra cloth layer: as the surface layer of the cushion, the Lycra cloth layer provides excellent elasticity and breathability, ensuring that the surface of the cushion is soft and comfortable when in contact with the skin, and can effectively maintain breathability to avoid a stuffy feeling due to long-term use.

[0077] TPU material layer: as the middle layer, the TPU layer has moderate hardness and elasticity, providing support while effectively protecting the memory cotton and gel layer below, prolonging the service life of the cushion. The wear resistance and durability of TPU material make the cushion can be used for a long time, and it is not easy to deform.

[0078] Gel layer: located below the TPU material layer, the gel layer can evenly disperse the pressure on the cushion, reducing the pressure on the hips and back, and improving comfort. The resilience of the gel layer allows it to recover its shape over time and is not prone to indentation.

[0079] First and second memory cotton layers: two layers of memory cotton provide strong support and soft comfort through different density designs. The first memory cotton layer with high density provides support effect, helping to maintain the overall shape of the cushion; the second memory cotton layer with low density increases the softness of the cushion, providing comfort. The combination of the two avoids discomfort caused by long-term sitting posture.

[0080] TPU anti-skid fabric layer: as the bottom layer of the cushion, the anti-skid fabric layer is designed with regular linear texture, which can better enhance the anti-skid performance of the cushion, avoiding sliding or shifting of the cushion during use.

[0081] Edge strip: the edge strip connects the layers of the cushion through line stitching, enhancing the edge strength of the cushion, avoiding edge wear or deformation, and also improving the appearance and overall stability of the cushion.

[0082] The multi-layer supporting structure cushion can provide long-time comfortable use experience, is suitable for various seats and long-time sitting posture requirements, and has the properties of durability, stability and anti-skid.

[0083] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, so any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, which does not deviate from the technical solution content of the present application, still belongs to the scope of the technical solution of the present application.
