[0035] See also Figures 1 to 4The embodiment of the present invention provides a seat cushion 100, comprising: a seat plate 101, a hollow area is provided in the middle; a bandage layer 102 is provided in the hollow area; a spring layer 103 is provided above the bandage layer 102, wherein the spring layer 103 includes a plurality of spring pockets 1031, each of the spring pockets 1031 is provided with at least one spring body 10311; a sponge layer 104 is arranged around the outside of the spring layer 103; and a surface layer 105 covers the sponge layer 104 and the spring layer 103.

[0036] This embodiment aims to solve the limitation problem of adjusting the rebound performance by a single sponge. This embodiment can effectively improve the rebound performance of the seat cushion 100 by setting a hollow area in the middle of the seat cushion 100 and adding a bandage layer 102 and a spring layer 103 in the hollow area. Specifically, the combination of the bandage layer 102 and the spring layer 103 can provide a better rebound effect while maintaining the comfort of the seat cushion 100.

[0037] Specifically, the seat plate 101 is the basic structure of the seat cushion 100, and the hollow area in the middle is used to accommodate the bandage layer 102. The bandage layer 102 is composed of a plurality of bandage bodies, which are connected to the seat plate 101 to form a support network. The spring layer 103 is located above the bandage layer 102, and each spring pocket 1031 contains at least one spring body 10311, and these spring pockets 1031 are distributed throughout the spring layer 103. The sponge layer 104 surrounds the outside of the spring layer 103 to provide additional comfort and support. The surface layer 105 covers the sponge layer 104 and the spring layer 103 to form the external contact surface of the seat cushion 100.

[0038] Through this structural design, the seat cushion 100 of this embodiment can provide different support forces and rebound effects at different parts. For example, the bandage layer 102 can be adjusted as needed to provide a stronger support force or a softer touch. The rebound performance of the seat cushion 100 can be adjusted by adjusting the height, waist diameter, circle diameter, number of circles, etc. of the spring bag 1031 in the spring layer 103 to achieve different rebound effects. The height and density of the sponge layer 104 can also be adjusted as needed to further optimize the overall performance of the seat cushion 100.

[0039] Compared with the prior art, the seat cushion 100 of this embodiment can achieve more flexible and efficient adjustment of the rebound performance by setting a hollow area in the middle of the seat plate 101, adding a bandage layer 102 and a spring layer 103, and combining the design of the sponge layer 104 and the surface layer 105, thereby providing a better sitting experience and effectively solving the limitation problem of adjusting the rebound performance by a single sponge in the prior art. In other words, the bandage layer 102 and the spring layer 103 provide multi-level support and rebound effects. In addition, the combined use of the sponge layer 104 and the surface layer 105 further improves the comfort and durability of the seat cushion 100.

[0040] Furthermore, the bandage layer 102 includes a plurality of bandage bodies connected to the seat plate 101 .

[0041] In this embodiment, the bandage body can provide additional support and rebound effects, thereby making up for the limitation of adjusting the rebound performance by relying solely on the sponge 1052 to a certain extent. Specifically, the bandage body can be made of high-strength elastic material, which can provide lasting support and rebound effects during use.

[0042] Furthermore, multiple bandage bodies are cross-arranged; or, multiple bandage bodies are laminated. In this embodiment, by adjusting the bandage process at the bottom of the seat cushion 100, the seat cushion rebound performance can be adjusted, thereby adjusting the sitting feel of the product. For example, the bandage body can be cross-arranged, so that uniform support and rebound effects can be provided in different directions. Alternatively, the bandage body can be laminated to further enhance the rebound effect by superimposing multiple layers of bandages. Under the same process, the effective sitting depth can be deepened by 3 to 5 mm by using multiple bandage bodies laminated. This solves the limitation problem of adjusting the rebound performance only by sponge 1052. Compared with the prior art, the technical solution of this embodiment can not only provide a better sitting experience, but also maintain good performance stability in different usage scenarios.

[0043] Specifically, the cross-setting of multiple bandage bodies can be achieved by arranging the bandages crosswise at a certain angle, so that support can be provided in different directions when subjected to force, thereby preventing the seat cushion 100 from being deformed locally. The laminated setting can make the bandage layer 102 thicker as a whole by stacking the bandage bodies layer by layer, thereby improving the rebound performance. Both of these settings can be adjusted according to specific needs to achieve the best sitting experience.

[0044] Furthermore, the width of each of the bandage bodies is 2-5 mm. In this embodiment, there is excellent feedback on the sitting experience during actual use. By designing the structure and process of the seat cushion 100, the user experience can be improved while effectively differentiating the subjective feelings of the product, and the differences in product structure and process can be presented in the use of the product. In the prior art, the adjustment of the resilience of the dining chair is generally carried out by adjusting the thickness of the sponge 1052, the density of the sponge 1052, the resilience of the sponge 1052, etc., to achieve the adjustment of the overall resilience of the seat cushion 100, and the adjustment range is 30% to 60%. The current problem is that the adjustment of the resilience of the overall seat cushion 100 is relatively limited only by adjusting the sponge 1052, and it cannot be improved after it is improved to a certain extent.

[0045] However, the bandage layer 102 of this embodiment is arranged in the hollow area, and a plurality of bandage bodies are connected to the seat plate 101, and the width of each bandage body is 2-5 mm. By adjusting the width of the bandage body, the resilience of the seat cushion 100 is further optimized, thereby improving the sitting experience of the dining chair in different postures.

[0046] Specifically, the width of the bandage body can be adjusted within the range of 2-5 mm according to specific needs. For example, a bandage body with a narrower width can provide a softer support effect, while a bandage body with a wider width can provide a more solid support effect. In other words, a bandage body with a width of 2 mm is suitable for a seat cushion 100 design that requires higher softness, while a bandage body with a width of 5 mm is suitable for a seat cushion 100 design that requires higher support. As a preferred embodiment, bandage bodies of different widths can be used in the same seat cushion 100 to achieve differentiated support effects in different areas.

[0047] Furthermore, the seat cushion 100 further includes a thin cotton felt, which is arranged between the spring layer 103 and the sponge layer 104. In this embodiment, the spring layer 103 provides the necessary support and elasticity to ensure that the seat cushion 100 can maintain its shape and comfort for a long time. The sponge layer 104 increases the softness and comfort of the seat cushion 100, so that the user can feel a softer touch when sitting down.

[0048] However, in actual use, over time, the spring pockets 1031 may gradually deform or sink due to various reasons (such as aging, wear, etc.). Without a proper isolation layer, these deformed spring pockets 1031 may directly press the sponge layer 104, causing the sponge layer 104 to be partially over-pressed, thereby affecting the overall comfort and service life of the seat cushion 100.

[0049] Therefore, in order to solve this problem, a thin cotton felt is added between the spring layer 103 and the sponge layer 104. The thin cotton felt has the characteristics of being soft, wear-resistant, and breathable, and can effectively isolate the spring bag 1031 and the sponge layer 104 to prevent direct contact between them. In this way, even if the spring bag 1031 is deformed or sunken to a certain extent, it will not cause excessive pressure on the sponge layer 104, thereby protecting the integrity of the sponge layer 104 and extending the service life of the seat cushion 100.

[0050] It should be noted that the thin cotton felt can be made of a variety of materials, such as polyester fiber or cotton fiber. The thickness of the thin cotton felt can be customized as needed to ensure air circulation inside the seat cushion 100 and reduce moisture and odor problems. The thin cotton felt can be arranged between the spring layer 103 and the sponge layer 104, or it can be covered on the entire spring layer 103. In a specific embodiment, the thickness of the thin cotton felt can be between 0.5-2 mm.

[0051] Furthermore, the surface layer 105 includes a sponge 1052 and silk floss 1051. In this embodiment, by adding the sponge 1052 and silk floss 1051 to the surface layer 105, the purpose is to improve the sitting experience of the dining chair seat cushion 100. The combined use of the sponge 1052 and the silk floss 1051 can provide a softer and more comfortable touch feeling, and can also improve the resilience of the seat cushion 100. Specifically, the sponge 1052 has good elasticity and support, while the silk floss 1051 is soft and breathable. The combination of the two can provide good support while increasing comfort and breathability, thereby improving the overall sitting experience.

[0052] The technical solution of this embodiment further optimizes the material combination of the surface layer 105 based on the structure of the traditional dining chair seat cushion 100. By using the sponge 1052 and the silk floss 1051 in the surface layer 105, the softness and comfort of the seat cushion 100 can be effectively improved, and the resilience of the seat cushion 100 can also be improved. Specifically, the combined use of the sponge 1052 and the silk floss 1051 can provide a better support effect and a more comfortable contact feeling, thereby making the dining chair more comfortable during use.

[0053] In a specific embodiment, the thickness of the sponge 1052 and the silk floss 1051 of the surface layer 105 is set to 2 cm sponge 1052 and 0.5 cm silk floss 1051. This design not only ensures sufficient support and softness, but also avoids stuffiness and airtightness caused by excessive thickness. At the same time, this thickness combination can also provide users with a more fitting and comfortable sitting experience.

[0054] Furthermore, the diameter of each of the spring bodies 10311 is 40-60 mm. In this embodiment, the resilience of the seat cushion 100 is achieved by providing a spring layer 103. The spring layer 103 is located above the bandage layer 102 and includes a plurality of spring pockets 1031, each of which is provided with at least one spring body 10311. In order to ensure the resilience of the spring layer 103, the diameter of each spring body 10311 is designed to be 40-60 mm. This design ensures the stability and consistency of the spring body 10311 during compression and recovery, thereby improving the overall resilience of the seat cushion 100.

[0055] Specifically, the diameter of the spring body 10311 is between 40-60 mm, which can be achieved by adjusting the height, waist diameter, coil diameter, number of coils and other parameters of the spring body 10311. The mechanical properties of spring bodies 10311 of different diameters are different during compression and recovery, and an appropriate diameter range can be selected as needed to meet the requirements of rebound performance in different usage scenarios. For example, a spring body 10311 with a larger diameter can provide greater support during compression, while a spring body 10311 with a smaller diameter can recover more quickly.

[0056] In a specific embodiment, the resilience of the seat cushion is adjusted by adjusting the technical parameters of the independent pocket spring bag 1031, thereby adjusting the sitting feel of the product; for example, the outer dimensions of the spring bag 1031 are changed from the original 250*250*50mm (4*4 arrangement), the diameter of the single pocket spring body 10311 is 60mm, the height is 50mm, the wire diameter is 1.8mm, and the number of turns is 4; the material of high carbon steel 70, the overall resilience of the seat cushion is 60-65%, and is adjusted to the outer dimensions of the spring bag 1031 of 240*240*30mm (6*6 arrangement), the diameter of the single pocket spring body 10311 is 40mm, the height is 30mm, the wire diameter is 1.2mm, and the number of turns is 4, and the overall resilience of the seat cushion can be adjusted to 65-75%.

[0057] Further, the thickness of the sponge layer 104 is 20-50 mm. In this embodiment, the thickness of the sponge layer 104 is increased to 20-50 mm, which can be achieved by selecting sponge 1052 materials of different thicknesses. For example, a sponge 1052 material with a thickness of 20 mm can be selected, which is suitable for occasions requiring lower resilience; a sponge 1052 material with a thickness of 50 mm can also be selected, which is suitable for occasions requiring higher resilience. Further, sponge 1052 materials of different thicknesses between 20-50 mm can be selected according to specific needs to achieve different resilience.

[0058] This embodiment provides a more flexible method for adjusting the resilience performance by increasing the thickness of the sponge layer 104 , which can improve the resilience performance of the seat cushion 100 within a wider range, thereby significantly improving the sitting experience of the dining chair.

[0059] Furthermore, the seat cushion 100 also includes an imitation leather layer 106 wrapped outside the surface layer 105, and the material of the imitation leather layer 106 is PVC material or EPU material. In the present embodiment, the imitation leather layer 106 is wrapped outside the surface layer 105, and the material of the imitation leather layer 106 can be PVC material or EPU material. PVC material, i.e. polyvinyl chloride, is a common synthetic plastic with good wear resistance and weather resistance. EPU material, i.e. environmentally friendly polyurethane, is a new environmentally friendly material with excellent softness and durability. The addition of this layer can not only improve the durability and aesthetics of the seat cushion 100, but also provide additional protection functions, so that the seat cushion 100 can still maintain good durability and aesthetics after long-term use.

[0060] There are many ways to implement the imitation leather layer 106. For example, the imitation leather layer 106 can be combined with the surface layer 105 by heat pressing to form a whole; or the imitation leather layer 106 can be fixed to the outside of the surface layer 105 by an adhesive. In addition, in actual applications, imitation leather layers 106 of different materials can be selected according to needs to achieve the best use effect.

[0061] In a specific embodiment, Figure 5 The figure shows the test results of the seat cushion rebound performance. This test uses professional equipment to simulate the process of a person sitting down and standing up. The rebound rate is determined by calculating the ratio of the area enclosed by the seat cushion deformation curves during these two actions. In other words, the ratio of the area enclosed by the two curves of the seat cushion is the rebound rate. Figure 5 The rebound rate is 69.3%. The horizontal axis represents the change in the thickness of the seat cushion, and the vertical axis represents the magnitude of the applied force. The standard test process is to gradually increase the force from 0 to 500 Newtons (N). According to the test results, the thickness of the seat cushion changes from -10mm to 32mm.

[0062] See also Figure 3 The embodiment of the present invention further provides a seat 200, comprising a base and a seat cushion 100, wherein the seat cushion 100 is disposed on the base, and the seat cushion 100 is a base as described in any one of the above items.

[0063] The technical solution of this embodiment aims to solve the problem of the limitation of adjusting the rebound performance of the current dining chair by setting the seat cushion 100 on the base and adopting the seat cushion 100 with a specific structure. Specifically, by introducing multiple technical features in the seat cushion 100, such as the hollow area, the bandage layer 102, the spring layer 103, the sponge layer 104, the surface layer 105, etc., the rebound performance of the entire seat cushion 100 is effectively improved and adjusted, thereby improving the user's sitting experience in different postures.

[0064] The design of the base can be adjusted according to actual needs, for example, it can be made of a variety of materials such as wood, metal or plastic. The specific structure and material selection of the seat cushion 100 can also be optimized according to different usage scenarios and needs, such as the cross setting or laminate setting of the bandage layer 102, the diameter range of the spring body 10311, the thickness range of the sponge layer 104, etc., can all be adjusted and optimized according to actual needs.

[0065] Therefore, through the technical solution of this embodiment, the overall resilience of the dining chair can be effectively improved, the user's sitting experience can be improved, and the limitation of the prior art that the adjustment is only performed through the sponge 1052 can be solved. Specifically, this embodiment introduces a multi-layer structure and a combination of different materials, so that the seat cushion 100 can provide good support and comfort in different postures, thereby improving the user's subjective experience.

[0066] In another specific embodiment, the effective contact area is tested using a body pressure distribution test device. Through this device, after a person sits on the actual seat product, a cloud map of contact pressure and area distribution can be displayed, and the effective area of ​​contact between the seat cushion and the person can be directly read. The greater the average pressure applied to the seat cushion, the larger the effective contact area, and the better the user's sitting experience.
