Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to an environmentally friendly automotive seat. Background Technology

[0002] Car seat cushions are a major consumer product for car owners. Nowadays, there are car seat cushions made of different materials such as genuine leather, microfiber leather, artificial leather, nylon, chemical fiber, artificial fur, and polyester wool on the market. Environmentally friendly car seat cushions mainly use recyclable materials and highly breathable materials, taking into account both comfort and environmental protection.

[0003] The existing patent document with authorized publication number CN217145735U discloses an antibacterial and antiviral car seat cushion, which includes a seat cushion body and a seat cushion cover. The seat cushion cover is wrapped around the outer surface of the seat cushion body. Both the seat cushion body and the seat cushion cover include an antibacterial layer. The outer surface of the seat cushion cover is provided with a flame retardant layer. The antibacterial layer of the seat cushion body includes a wear-resistant layer, a cushioning layer, and an anti-slip layer. The cushioning layer includes multiple cushioning springs installed in the cushioning layer. The multiple cushioning springs are evenly distributed in the cushioning layer.

[0004] However, the aforementioned existing technologies still have the following problems:

[0005] The multiple buffer springs installed in the aforementioned buffer layer are fixedly connected to the buffer layer body. During long-term daily use, the buffer springs inside the buffer layer will fail, reducing their rebound force. In existing car seat cushions, once some buffer springs fail, the entire car seat cushion is often replaced, and it is not possible to replace the damaged buffer springs individually. This makes the use cost of car seat cushions high and causes unnecessary waste. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an environmentally friendly car seat cushion. This invention features multiple modular spring units that can be installed and disassembled independently, effectively solving the technical problem in existing technologies where the entire cushion needs to be replaced if a single or partial spring fails.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An environmentally friendly car seat cushion includes a seat cover, a cushioning pad, and an anti-slip pad. The seat cover has an opening at the bottom and is fitted onto the cushioning pad. One end of the anti-slip pad is connected to the seat cover via a telescopic strap, and the other three sides of the anti-slip pad are detachably connected to the bottom of the seat cover via zippers. When the zippers are closed, the anti-slip pad seals the opening and abuts against the bottom of the cushioning pad. The seat cover and the anti-slip pad cooperate to completely cover the cushioning pad. The cushioning pad is composed of a sponge layer and an elastic layer.

[0009] The bottom of the sponge layer has multiple grooves arranged in a matrix;

[0010] The elastic layer is composed of multiple independent spring units, each spring unit including a stainless steel spring and a Kub bag that wraps the stainless steel spring;

[0011] Each spring unit is independently and detachably snapped into its corresponding groove.

[0012] Furthermore, a soft magnetic sticker is fixedly provided on the top wall of the groove, and the top of the steel spring is directly adsorbed and fixed to the soft magnetic sticker through the top wall of the Kubu bag.

[0013] Furthermore, the shape and size of the groove are matched to the spring unit so that the spring unit remains stable after being embedded.

[0014] Furthermore, the lower end portion of the spring unit extends outside the groove.

[0015] Furthermore, the anti-slip mat consists of an anti-slip layer and a first wear-resistant layer. The anti-slip layer is fixed to the lower end of the first wear-resistant layer. When the zipper is closed, the top of the first wear-resistant layer abuts against the bottom of several spring units.

[0016] Furthermore, the seat cover is composed of a base layer and a second wear-resistant layer, the second wear-resistant layer is fixed to the upper end of the base layer, and the zipper is disposed between the base layer and the anti-slip layer.

[0017] Furthermore, the outer wall of the Kubbag is provided with an annular protrusion, the diameter of which is slightly larger than the diameter of the groove, and an interference fit is formed between the annular protrusion and the groove.

[0018] Furthermore, a number of rubber blocks arranged in a rectangular array are fixed to the bottom of the anti-slip layer.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention enables independent replacement of spring units, fundamentally solving the biggest pain point of existing technologies. When a single spring unit fails, it is not necessary to replace the entire seat cushion; only the damaged unit needs to be replaced, significantly reducing maintenance costs, minimizing resource waste, and improving product lifespan and environmental friendliness.

[0021] This utility model is easy to maintain and operate: the anti-slip pad can be removed by zipping to open the opening, making all spring units directly exposed and accessible, and the replacement operation is simple and quick, which is easy for users or maintenance personnel to implement.

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] Example 1

[0034] like Figure 1-8As shown, an environmentally friendly car seat cushion includes a seat cover 1, a cushioning pad, and an anti-slip pad 3. The seat cover 1 has an opening at the bottom and is fitted onto the cushioning pad. One end of the anti-slip pad 3 is connected to the seat cover 1 via a telescopic strap 5, and the other three sides of the anti-slip pad 3 are detachably connected to the bottom of the seat cover 1 via zippers 4. When the zippers 4 are closed, the anti-slip pad 3 seals the opening and abuts against the bottom of the cushioning pad. The seat cover 1 and the anti-slip pad 3 cooperate to completely cover the cushioning pad. The cushioning pad is composed of a sponge layer 6 and an elastic layer 7. The bottom of the sponge layer 6 has multiple grooves 11 arranged in a matrix. The elastic layer 7 is composed of multiple independent spring units 8. Each spring unit 8 includes a steel spring 9 and a woven fabric bag 10 that wraps the steel spring 9. The woven fabric bag 10 is made of woven fabric, which is a thick, tough, and tear-resistant fabric, usually made of continuous cotton or synthetic fibers interwoven together. Kub is a thick, tough, and tear-resistant fabric, usually made of continuous cotton or synthetic fibers woven together in both directions.

[0035] Each spring unit 8 is independently and detachably snapped into a corresponding groove 11. The shape and size of the groove 11 match the spring unit 8 to ensure stability after insertion. The bag 10 can wrap around the steel spring 9, effectively preventing wear on the sponge layer 6 during extension and retraction. The lower part of the spring unit 8 extends outside the groove 11. When the anti-slip pad 3 is opened, the bottom of the spring unit 8 is directly exposed to the accessible area, facilitating gripping, disassembly, and installation with fingers or tools.

[0036] All spring units 8 can be directly exposed and accessed by removing the anti-slip pad 3 through the zipper 4. The replacement operation is simple and quick, and easy for users or maintenance personnel to implement.

[0037] A soft magnetic sticker 12 is fixedly installed on the top wall of the groove 11, and the top of the steel spring 9 is directly adsorbed and fixed to the soft magnetic sticker 12 through the top wall of the bag 10.

[0038] The soft magnetic sticker 12 uses a rubber magnet or flexible magnetic sheet, approximately 1-3mm thick, and is flexible and cuttable, conforming to the curved shape of the inner top wall of the groove 11. The soft magnetic sticker 12 is fixed to the inner top wall of the groove 11 of the sponge layer 6 via adhesive backing or heat-pressing embedding. This structure is a non-permanent and easily detachable fixing method; the unit can be removed simply by overcoming the magnetic force during disassembly, and automatically attaches during installation, making operation extremely simple. Furthermore, the magnetic attraction maintains sufficient connection strength even under vehicle vibration, preventing accidental detachment of the unit. It is easier to operate and less prone to damage than mechanical connections such as clips or threads.

[0039] like Figure 3-7As shown, the anti-slip mat 3 consists of an anti-slip layer 13 and a first wear-resistant layer 14. The anti-slip layer 13 is fixed to the lower end of the first wear-resistant layer 14. When the zipper 4 is closed, the top of the first wear-resistant layer 14 abuts against the bottom of several spring units 8. The seat cover 1 consists of a base layer 15 and a second wear-resistant layer 16. The second wear-resistant layer 16 is fixed to the upper end of the base layer 15. The zipper 4 is located between the base layer 15 and the anti-slip layer 13. Several rectangular arrays of rubber blocks 2 are fixed to the bottom of the anti-slip layer 13. The rubber blocks 2 can effectively enhance the friction between the seat cushion and the surface of the car seat, prevent the seat cushion from sliding, and improve safety.

[0040] When the zipper 4 is closed, the top of the first wear-resistant layer 14 abuts against the bottom of several spring units 8. When the anti-slip pad 3 is installed in place, i.e., when the zipper 4 is closed, the wear-resistant layer presses upward against the bottom of all exposed spring units 8. This provides a downward restraining force, effectively preventing the spring units 8 from bouncing upward or detaching from the groove 11 due to pressure during use, especially on bumpy roads. Together with the upward adsorption of the soft magnet 12 and the matching shape and size of the groove 11 with the spring units 8, it forms a stable yet removable restraining structure. At the same time, the wear-resistant layer protects the bottom of the spring units 8 from direct friction damage.

[0041] The specific operation method of Embodiment 1 of this utility model is as follows:

[0042] When it is necessary to replace some or a single spring unit 8: Open the zipper 4 and disassemble the anti-slip pad 3 three times to open the opening, so that all spring units 8 can be directly exposed and touched. The on-site operator can press down on each spring unit 8 to observe the elastic effect, and remove the spring unit 8 whose elasticity is damaged, and reinstall the new spring unit 8. Then close the zipper 4 so that the top of the first wear-resistant layer 14 abuts against the bottom of several spring units 8.

[0043] This novel embodiment enables independent replacement of the spring unit 8, fundamentally solving the biggest pain point of the prior art. When a single spring unit 8 fails, it is not necessary to replace the entire seat cushion; only the damaged unit needs to be replaced, significantly reducing maintenance costs, minimizing resource waste, and improving product lifespan and environmental friendliness.

[0044] All spring units 8 can be directly exposed and accessed by removing the anti-slip pad 3 through the zipper 4. The replacement operation is simple and quick, and easy for users or maintenance personnel to implement.

[0045] The modular design ensures that undamaged spring units 8 continue to function normally, maintaining the overall cushioning comfort of the seat and preventing large-area functional loss due to localized damage.

[0046] Example 2

[0047] like Figure 9As shown, the outer wall of the Kubbag 10 is provided with an annular protrusion 17, the diameter of the annular protrusion 17 is slightly larger than the diameter of the groove 11, and an interference fit is formed between the annular protrusion 17 and the groove 11.

[0048] The advantage of this second embodiment compared to the first embodiment is that the outer wall of the Kubbag 10 is provided with an annular protrusion 17. The diameter of the annular protrusion is slightly larger than the diameter of the groove 11. An interference fit is formed between the annular protrusion 17 and the groove 11. When the spring unit 8 is inserted into the groove 11, the annular protrusion 17 and the wall of the groove 11 generate elastic compression, providing radial friction. This enhances the lateral stability of the spring unit 8 in the groove 11, preventing it from moving horizontally, rotating, or easily falling out. The interference fit design ensures pluggability.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
