Description

Technical Field

[0001] This utility model relates to the field of office chair equipment technology, and in particular to an office chair seat cushion sponge structure. Background Technology

[0002] Office chairs refer to various chairs provided for convenience in daily work and social activities. OfficeMate categorizes office chairs into narrow and broad definitions. The narrow definition refers to chairs with backrests used for desk work while seated. The broad definition encompasses all chairs used in offices, including executive chairs, mid-level chairs, meeting chairs, staff chairs, conference chairs, visitor chairs, and training chairs. The seat cushion, as an important component of the chair, is generally connected to the chair frame for the user to sit on. Existing seat cushions, when used, exhibit significant deformation under the buttocks, easily pulling the cushion around the sides and legs, resulting in a straightened, arched shape and poor comfort. Utility Model Content

[0003] In order to address the technical deficiencies mentioned in the background section, the purpose of this utility model is to provide a sponge structure for office chair seat cushions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An office chair seat cushion foam structure includes a seat cushion, the upper surface of which is provided with a thigh support area corresponding to the human thigh and a thigh support area corresponding to the human thigh. The thigh support area and / or the thigh support area are provided with multiple grooves; the multiple grooves together with the base part of the seat cushion form a pressure deformation space.

[0006] By adopting the above technical solution, multiple grooves are set in at least one area of ​​the groin support area and the thigh support area, thereby providing more deformation space on the base surface of the seat cushion. This reduces the tensile force between the groin support area and the thigh support area, minimizing their mutual influence. When the user sits down, the deformation is quicker and more comfortable, thus improving the user's experience and comfort. Furthermore, the multiple grooves also improve breathability and heat dissipation, effectively reducing the user's feeling of stuffiness.

[0007] Furthermore, the multiple grooves include multiple first grooves and multiple second grooves. The multiple first grooves are arranged parallel to each other along a first direction, and the multiple second grooves are arranged parallel to each other along a second direction, which is more aesthetically pleasing and results in more balanced deformation under pressure.

[0008] Furthermore, the groove depth at both ends of each of the first grooves and each of the second grooves is set to the minimum, while the groove depth at the center of each of the first grooves and each of the second grooves is set to the maximum, which can provide more space for pressure deformation and thus provide greater comfort.

[0009] Furthermore, the central axis of each of the first grooves and each of the second grooves is designed as an arc-shaped structure, which conforms to ergonomics and can provide users with reasonable and comfortable support.

[0010] Furthermore, the upper surface of the seat cushion has a recessed area in the middle to avoid the coccyx, which can prevent the seat cushion from pressing against the coccyx and make it more comfortable.

[0011] Furthermore, the seat cushion has a U-shaped recessed area in the middle of the side of the groin support area opposite to the thigh support area. The upper and outer surfaces of the recessed area are open, providing room for deformation, making processing more convenient and faster, and reducing costs.

[0012] Furthermore, a smooth transition zone is provided between the groin support area and the thigh support area. The transition zone has a curved profile in the lateral direction and is set at the same height in the longitudinal direction, ensuring the continuity and comfort of the support.

[0013] Furthermore, each side of the seat cushion is provided with a set of groin support areas and a set of thigh support areas. A saddle-shaped raised band is provided between two adjacent sets of groin support areas and two adjacent sets of thigh support areas. The saddle-shaped raised band has a curved profile in both the transverse and longitudinal directions. This saddle-shaped raised band conforms to load-bearing mechanics, can improve load-bearing strength, prevent excessive deformation, and improve comfort.

[0014] Furthermore, the lateral width of the saddle protrusion is set to decrease along the longitudinal direction close to the thigh support area (13), which can ensure the support force of the thigh support area and also provide more deformation space for the thigh support area.

[0015] Furthermore, the lower surface of the seat cushion is provided with a recessed mounting groove for mounting a base plate. The base plate is fixedly connected to the base of the office chair to support and fix the seat cushion, making installation and disassembly more convenient and saving costs.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] This invention incorporates multiple grooves in at least one area of ​​the groin support zone and the thigh support zone, providing more deformation space on the base surface of the seat cushion. This reduces the tensile force between the groin and thigh support zones, minimizing their mutual influence. The cushion deforms more quickly after the user sits down, resulting in greater comfort and an improved user experience. Furthermore, the multiple grooves enhance breathability and heat dissipation, effectively reducing stuffiness. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this utility model will be described in further detail below.

[0028] An office chair seat cushion sponge structure 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a seat cushion 11, the upper surface of which is provided with a thigh support area 12 corresponding to the human thigh and a thigh support area 13 corresponding to the human thigh. The thigh support area 12 and / or the thigh support area 13 are provided with multiple grooves. The grooves and the base part of the seat cushion 11 together form a pressure deformation space.

[0029] Multiple grooves are provided in at least one area of ​​the groin support area 12 and the thigh support area 13, thereby providing more deformation space for the base surface of the seat cushion 11. This reduces the tensile force between the groin support area 12 and the thigh support area 13, minimizing their mutual influence. When the user sits down, the deformation is quicker, making it more comfortable to use and improving the user's experience and comfort. Furthermore, the multiple grooves also improve breathability and heat dissipation, effectively reducing the user's stuffiness. Preferably, both the groin support area 12 and the thigh support area 13 are provided with multiple grooves.

[0030] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 The multiple grooves include multiple first grooves 14 and multiple second grooves 15. The multiple first grooves 14 are arranged parallel to each other along a first direction, and the multiple second grooves 15 are arranged parallel to each other along a second direction, which is more aesthetically pleasing and results in more balanced deformation under pressure. Of course, the multiple first grooves 14 and multiple second grooves 15 can be arranged at an angle in a grid pattern, or the first direction and the second direction can be perpendicular to each other, so that the shape of a single area enclosed by two adjacent first grooves 14 and two corresponding adjacent second grooves 15 is square.

[0031] Preferably, the spacing between two adjacent first grooves 14 and the spacing between two adjacent second grooves 15 are set to be the same, which is more aesthetically pleasing, provides better support, and makes sitting more comfortable.

[0032] For preferred options, please refer to [the provided text]. Figure 2 , Figure 3 Because the force on different parts of the seat cushion 11 is different, the deformation requirements of the base of the seat cushion 11 are also different. The groove depth at both ends of each first groove 14 and each second groove 15 is set to the minimum, and the groove depth at the center of each first groove 14 and each second groove 15 is the maximum. The thigh support area 12 is the deepest recessed here, which can provide more space for pressure deformation and higher comfort.

[0033] For details, please refer to Figure 2 , Figure 3 The central axis of each first groove 14 and each second groove 15 is set as an arc-shaped structure, which smoothly supports the user and conforms to ergonomics, so that the user can obtain reasonable and comfortable support.

[0034] In some embodiments, please refer to Figure 2 , Figure 4 The upper surface of the seat cushion 11 has a recessed area 16 in the middle to avoid the coccyx, which can prevent the seat cushion 11 from pressing against the coccyx and make it more comfortable.

[0035] Preferably, the seat cushion 11 has a U-shaped recessed area 16 in the middle of the side of the thigh support area 12 away from the thigh support area 13. The upper surface and outer side of the recessed area 16 are both open, which can provide deformation space, making processing more convenient and faster, and reducing costs.

[0036] In some embodiments, please refer to Figure 1 , Figure 2 A smooth transition zone 17 is provided between the groin support area 12 and the thigh support area 13. The transition zone 17 is curved in the lateral direction and is set at the same height in the longitudinal direction, which ensures the continuity and comfort of the support, and can also play a role in preventing slipping and excessive deformation, providing more support.

[0037] In some embodiments, please refer to Figure 1 , Figure 2 The seat cushion 11 has a set of groin support areas 12 and thigh support areas 13 on both sides. A saddle-shaped raised band 18 is provided between two adjacent sets of groin support areas 12 and two adjacent sets of thigh support areas 13. The saddle-shaped raised band 18 is curved in both the transverse and longitudinal directions. The saddle-shaped raised band 18 conforms to load-bearing mechanics, can improve load-bearing strength, avoid excessive deformation, and improve comfort.

[0038] Specifically, the saddle-shaped protrusion 18 and the recessed area 16 are located in the same longitudinal direction. One end of the saddle-shaped protrusion 18 is located between the two sets of thigh support areas 12, and the other end of the saddle-shaped protrusion 18 is located between the two sets of thigh support areas 13. The two sets of thigh support areas 12 and the two sets of thigh support areas 13 are symmetrically arranged along the central axis of the saddle-shaped protrusion 18. The lateral width of the saddle-shaped protrusion 18 decreases along the longitudinal direction closer to the thigh support area 13, which can ensure the support force of the thigh support area 12 and also provide more deformation space for the thigh support area 13.

[0039] In some embodiments, please refer to Figure 2 The lateral width of the groin support area 12 is smaller than that of the thigh support area 13, which can increase the support area of ​​the leg, provide a greater deformation space and range, and improve the comfort of the leg.

[0040] In some embodiments, please refer to Figure 3 , Figure 4 The lower surface of the seat cushion 11 is provided with a recessed mounting groove 111 for mounting the base plate 2. The base plate 2 is fixedly connected to the base of the office chair to support and fix the seat cushion 11. Preferably, the thickness of the base plate 2 is the same as the thickness of the mounting groove 111, that is, the lower surface of the base plate 2 is flush with the lower surface of the seat cushion 11, which makes installation and disassembly more convenient and saves costs.

[0041] Furthermore, the seat cushion 11 is made of a flexible material, while the base plate 2 is made of a hard material. The seat cushion 11 is located on the outside of the thigh support area 13 and protrudes from the base plate 2, which makes it easy to adapt to the support height of the outside of the thigh support area 13 corresponding to different sitting postures, thereby improving the comfort of the user's legs.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
