Description

Technical Field

[0001] This utility model relates to the field of seat cushion technology, and in particular to a pressure-relieving seat cushion. Background Technology

[0002] As people's living standards improve and their pursuit of health and comfort grows, seat cushions, as a widely used item in daily life, have a significant impact on users' comfort, health, and user experience through their design and material selection.

[0003] Most seat cushions on the market are currently made of cotton, silicone, or similar materials.

[0004] 1. Cotton seat cushions have poor breathability;

[0005] 2. Silicone seat cushions are usually solid in design. The solid structure has poor adjustment effect on the pressure on the buttocks and thighs, resulting in concentrated pressure. This concentrated pressure can cause discomfort in the buttocks or thighs. Utility Model Content

[0006] In order to solve at least one of the above-mentioned technical problems, the purpose of this utility model is to provide a pressure-relieving seat cushion.

[0007] To achieve the above objectives, the pressure-relieving seat cushion proposed in this utility model includes:

[0008] The first layer has an adjustment area, which is configured with a hollow structure and has multiple first cavities. The first cavities are used to adjust the pressure received by the pressure-relieving cushion.

[0009] When the first cavity is compressed, the first cavity deforms; when the first cavity is decompressed, the first cavity returns to its original shape.

[0010] In one embodiment, the adjustment area is provided with a plurality of support blocks arranged at intervals, and adjacent support blocks are connected by a connecting part;

[0011] The multiple support blocks and the connecting parts form a hollow structure, and the first cavity is located on the support block.

[0012] In one embodiment, the first cavity is formed on the surface of the support block.

[0013] In one embodiment, the first layer has a pressure-bearing surface and a back surface;

[0014] The opening of the first cavity faces the back side.

[0015] In one embodiment, the first cavity is configured as a bowl-shaped structure.

[0016] In one embodiment, the connecting portion is configured as a rod-shaped structure, and the opening of the first cavity is located below the connecting portion.

[0017] In one embodiment, the support block has a top surface facing away from the cavity opening, and the top surface is located above the connecting portion.

[0018] In one embodiment, the plurality of support blocks are arranged in a matrix.

[0019] In one embodiment, the first layer is configured as EVA material or silicone material;

[0020] And / or, the first layer is configured as a one-piece molded structure.

[0021] In one embodiment, the pressure-relieving cushion further includes a second layer installed on top of the first layer, the second layer being in contact with the user.

[0022] The technical solution of this utility model adopts a hollow structure adjustment area with multiple first cavities. This hollow structure enables the cushion to be breathable, and its breathability is significantly improved compared to cotton cushions. The first cavities allow for adjustment of hip and thigh pressure. Compared to solid silicone cushions in the prior art, the inclusion of first cavities creates a partially hollow structure inside the cushion, further enhancing its ability to adjust hip and leg pressure. This results in a cushion with better breathability and hip and thigh pressure adjustment, thus solving the problems of existing cushions' inability to effectively adjust hip and thigh pressure and poor breathability.

[0036] As people's living standards improve and their pursuit of health and comfort grows, seat cushions, as a widely used item in daily life, have a significant impact on users' comfort, health, and user experience through their design and material selection.

[0037] Most seat cushions on the market are made of cotton or silicone, but existing seat cushions cannot effectively adjust the pressure on the buttocks and thighs, and their breathability is poor.

[0038] This utility model proposes a pressure-relieving seat cushion.

[0039] Please see Figure 1 , Figure 2 , Figure 3 In one embodiment of this utility model, the pressure-relieving cushion includes:

[0040] In one embodiment, the first layer 100 is further configured as an EVA material or a silicone material. It should be noted that EVA and silicone materials allow the first layer 100 to have a certain degree of elasticity. The first layer 100 is provided with an adjustment area; it can be understood that in this embodiment, the entire first layer 100 is an adjustment area. However, this design is not limited to this. In some embodiments, only 1 / 2, 1 / 3, 1 / 4, 9 / 10, or 8 / 10 of the first layer 100 is provided with an adjustment area. The adjustment area is configured with a perforated structure. It should be noted that this perforated structure allows the first layer 100 to be breathable, enabling ventilation when the user uses the cushion. Furthermore, the adjustment area has multiple first cavities 200, which are used to adjust the pressure received by the pressure-relieving cushion. When a user sits on the cushion, the first layer 100 is compressed, causing the first cavities 200 to deform. During this deformation, the first cavities 200 effectively regulate the pressure on the user's buttocks and thighs. Furthermore, when the first cavities 200 are configured as closed cavities, the air inside cannot escape when the first cavities 200 deform, thus buffering the pressure on the buttocks and thighs and regulating their pressure. When the first cavity 200 is configured as a cavity with an opening, when the first cavity 200 deforms, the gas inside can be discharged outward through the opening. At this time, the first cavity 200 can release pressure on the buttocks and thighs, thereby regulating the pressure on these areas. When the user leaves the cushion, the first cavity 200 is relieved of pressure and recovers its deformation under the action of the elastic material. It should be noted that when the user's buttocks or thighs move during use of the cushion, the first cavity 200 can deform to varying degrees according to the pressure changes.

[0041] It should be noted that this embodiment employs a hollowed-out adjustment area with multiple first cavities 200. This hollowed-out structure provides breathability to the cushion, significantly improving its breathability compared to cotton cushions. The first cavities 200 allow for adjustment of hip and thigh pressure. Compared to solid silicone cushions in the prior art, the inclusion of first cavities 200 creates a partially hollow structure within the cushion, further enhancing its ability to adjust hip and thigh pressure. This results in better breathability and hip and thigh pressure adjustment, thus addressing the problems of existing cushions' inability to effectively adjust hip and thigh pressure and their poor breathability.

[0042] Furthermore, in this embodiment, the first layer 100 is an adjustable area, which means that the first layer 100 is provided with multiple first cavities 200. The multiple first cavities 200 enable the pressure on the buttocks and thighs to be better distributed when the first layer 100 is under pressure, reducing the possibility of pressure concentration, making the sitting posture more comfortable, and reducing pain caused by local pressure.

[0043] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 The adjustment area is provided with a plurality of spaced-apart support blocks 300, and adjacent support blocks 300 are connected by a connecting part 400; the plurality of support blocks 300 and the connecting part 400 form a hollow structure, and the first cavity 200 is provided in the support block 300. Further, in some embodiments, the first cavity 200 may be provided in the support block 300 in a non-open form or in an open form.

[0044] However, this design is not limited to this. In some embodiments, the hollow structure can be formed by interlacing the connecting portions 400 of multiple rod-shaped structures. In this case, the first cavity 200 is formed in the connecting portion 400.

[0045] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 The first cavity 200 is formed on the surface of the support block 300. It can be understood that when the first cavity 200 is formed on the surface of the support block 300, the first cavity 200 has an opening. Under the action of the opening, when the first cavity 200 is deformed by pressure, the gas in the first cavity 200 can be discharged outward through the opening, thereby achieving the purpose of pressure release.

[0046] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 The first layer 100 has a pressure-bearing surface 110 and a back surface 120; the opening 210 of the first cavity 200 faces the back surface 120. However, this design is not limited to this. In some embodiments, the opening 210 of the first cavity 200 may face to one side, that is, it may be located between the pressure-bearing surface 110 and the back surface 120. It should be noted that having the opening 210 of the first cavity 200 facing the back surface 120 provides better support for the first cavity 200 compared to having the opening 210 of the first cavity 200 facing to one side.

[0047] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 The first cavity 200 is configured as a bowl-shaped structure. It can be understood that when the first cavity 200 adopts a bowl-shaped structure, the size of the cavity opening 210 is relatively large, which facilitates the gas in the first cavity 200 to be discharged outward.

[0048] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 The connecting part 400 is configured as a rod-shaped structure. The cavity opening 210 of the first cavity 200 is located below the connecting part 400. It can be understood that there is a preset distance between the cavity opening 210 and the connecting rod. Under the action of the preset distance, the first cavity 200 can have a better collapse stroke, thereby making the support block 300 have a better deformation.

[0049] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 The support block 300 has a top surface 310 facing away from the cavity 210. The top surface 310 is located above the connecting part 400. It can be understood that when the top surface 310 is located above the connecting part 400, compared to when the top surface 310 is parallel to the top of the connecting part 400, the deformation of the support block 300 can be further increased.

[0050] In one embodiment, reference Figure 1 , Figure 2 The multiple support blocks are arranged in a matrix. It should be noted that when the multiple support blocks are distributed in a matrix, the seat cushion can form an array-like cushioning. However, this design is not limited to this. In some embodiments, the multiple support blocks can be distributed in a ring or a spiral, etc.

[0051] In one embodiment, the first layer 100 is configured as an integrally formed structure. This is to facilitate the production and processing of the first layer 100 and to facilitate the forming of the first cavity 200. Depending on the material of the first layer 100, different processing techniques can be used for integral forming.

[0052] In one embodiment, the pressure-relieving cushion further includes a second layer (not shown), which is installed on the first layer 100 and is used to contact the user. The second layer is disposed on the pressure-receiving surface 110 of the first layer 100. However, this design is not limited to this; in some embodiments, the second layer may be disposed on the back side 120 of the first layer 100. However, this design is not limited to this; in some embodiments, the pressure-relieving cushion further includes a third layer, where the first layer 100 may be disposed between the second and third layers. Further, in some embodiments, the first layer 100 and the third layer may be made of non-woven fabric or other cloth materials, and the first layer 100 and the third layer may be installed on the first layer 100 by adhesive bonding. Further, in some embodiments, when the pressure-relieving cushion includes only the second layer, the second layer may also wrap around the first layer 100.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
