Description

Technical Field

[0001] This utility model relates to the field of household goods technology, specifically to a Ula grass seat cushion. Background Technology

[0002] Seat cushions are common household items used in daily life, and are widely used in chairs, sofas, cars and other scenarios. Their main function is to provide users with a comfortable riding experience. At present, there are many types of seat cushions on the market, with different filling materials, such as sponge, cotton, down and chemical fiber.

[0003] However, these traditional filling materials for seat cushions have many shortcomings. While sponge cushions have good elasticity, they lack breathability, causing users' buttocks to sweat easily in hot weather, resulting in a stuffy feeling. Prolonged use may also breed bacteria. Cotton cushions have relatively good breathability, but their resilience is poor, and they tend to collapse and lose their support after a period of use. Down cushions offer good warmth and comfort, but they are expensive and tend to clump together when damp, affecting the user experience. Synthetic fiber cushions are cheaper, but their breathability and environmental friendliness are poor, and some people may experience skin allergies. Ordinary cotton cushions have poor breathability and are prone to bacterial growth. Therefore, we have proposed a Ula grass cushion to solve the above-mentioned problems. Utility Model Content

[0004] In response to the shortcomings of existing technologies, this utility model provides a grass cushion that solves the problems of poor breathability and stuffiness caused by bacteria growth.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grass cushion, comprising:

[0006] Two layers of fabric cover the upper and lower exterior of the seat cushion;

[0007] The Ula grass filling felt layer is placed between the two sets of fabric layers and is made of Ula grass fibers and non-woven fabric through a needle punching process.

[0008] The edging is provided at the edge between the fabric layer and the Ula grass filling felt layer.

[0009] Preferably, the fabric layer is a natural fiber antibacterial fabric with evenly distributed breathable pores on its surface.

[0010] Preferably, the natural fiber antibacterial fabric can be cotton, ramie, linen, hemp, or bamboo fiber.

[0011] Preferably, the outer surface of both sets of fabric layers is provided with anti-slip texture, which is a diamond pattern or a wave pattern.

[0012] Preferably, the edging is fixed with high-strength polyester sewing thread through a double-line overlock process, and the inner side of the edging is provided with elastic ribs, which are made of TPU or spandex.

[0013] Preferably, the cushion is rectangular, circular, or ergonomically curved, suitable for use with chairs and sofas.

[0014] Preferably, the Ula grass filling felt layer is mixed with 5%-10% of its total mass of Artemisia argyi fiber, the Artemisia argyi fiber being 3-5cm in length, and distributed with Ula grass fiber through a cross-laying process.

[0015] Preferably, the cushion has a removable and washable zipper on one side edge, the zipper length being 1 / 2 of the cushion circumference, and a waterproof and breathable membrane is provided between the fabric layer and the Ula grass filling felt layer, the waterproof and breathable membrane being a polytetrafluoroethylene microporous membrane.

[0016] Beneficial effects

[0017] This utility model provides a grass cushion. Compared with the prior art, it has the following advantages:

[0018] This Ula grass seat cushion features a needle-punched porous structure in the Ula grass filling layer, combined with breathable pores in the fabric layer, forming a three-dimensional breathable system. Compared to sponge cushions, it offers better air circulation, reducing stuffiness and sweating in summer and providing superior perspiration wicking. The needle-punching process tightly bonds the Ula grass fibers to the non-woven fabric, resulting in better resilience than cotton and preventing significant sagging even after long-term use. The natural antibacterial components of Ula grass, combined with the antibacterial fabric, are achieved without chemical adhesives through the needle-punching process, effectively reducing bacterial growth compared to ordinary synthetic fiber cushions and eliminating odor release, thus solving the problem of bacterial growth in sponge and synthetic fiber cushions. Ula grass has better moisture resistance than down, and it does not clump when damp. Furthermore, its multi-scene design and temperature regulation performance provide warmth in winter and coolness in summer, avoiding the limitations of traditional cushions' poor seasonal applicability. This cushion also keeps the buttocks dry, reducing blood circulation issues caused by dampness and thus decreasing the likelihood of hemorrhoids.

[0019] Ula grass, a natural herbaceous plant, has many excellent properties. Its fibers are long, soft, and elastic, with good breathability. It also has antibacterial, deodorizing, and warming effects, making it an ideal natural filling material that meets the needs of seat cushions. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-3 As shown:

[0026] A grass cushion includes: two sets of fabric layers 102, which cover the upper and lower exterior of the cushion;

[0027] The Ula grass filling felt layer 101 is placed between two sets of fabric layers 102 and is made of Ula grass fiber and non-woven fabric through a needle punching process.

[0028] The edging 103 is located at the edge between the fabric layer 102 and the Ula grass filling felt layer 101.

[0029] The cushions are rectangular, circular, or ergonomically curved, suitable for chairs and sofas.

[0030] In this embodiment: the Ula grass filling felt layer 101 is made of Ula grass fiber and polypropylene nonwoven fabric through needle punching process to form a uniform felt body of a certain thickness; the edge of the fabric layer 102 and the Ula grass filling felt layer 101 are sewn together by the edge binding 103.

[0031] The Ula grass filling felt layer 101 achieves a firm bond between fibers and non-woven fabric through needle punching, avoiding the problems of clumping and collapse of traditional filling materials, and ensuring the structural stability of the cushion for long-term use. The double-layer fabric layer 102 covers and forms a physical protective barrier to isolate external stains and friction from damage to the Ula grass filling felt layer 101. The edge binding 103 fixes the three-layer structure to prevent edge delamination, ensures uniform stress distribution, and is suitable for long-term sitting scenarios.

[0032] This design utilizes the needle-punched porous structure of the Ula grass filling layer 101 and the breathable pores of the fabric layer 102 to form a three-dimensional breathable system. Compared to sponge cushions, it offers better air circulation, reducing stuffiness and sweating in summer. The needle-punching process tightly bonds the Ula grass fibers to the non-woven fabric, resulting in better resilience than cotton and no significant sagging even after long-term use. The natural antibacterial components of Ula grass, combined with the antibacterial fabric, achieve the absence of chemical adhesives through the needle-punching process, effectively reducing bacterial growth rates compared to ordinary synthetic fiber cushions and eliminating odor release, thus solving the problem of bacterial growth in sponge and synthetic fiber cushions. Ula grass has better moisture resistance than down, and it does not clump when damp. In addition, its multi-scene design and temperature regulation performance provide warmth in winter and coolness in summer, avoiding the limitations of traditional cushions' poor seasonal applicability.

[0033] Ula grass filling layer 101 uses Ula grass, a natural herbaceous plant, which has many excellent properties. Its fibers are fine, soft and elastic, and have good breathability. It also has antibacterial, deodorizing and warming effects, making it an ideal natural filling material to meet the needs of seat cushion use.

[0034] Furthermore;

[0035] In an optional embodiment, the fabric layer 102 is a natural fiber antibacterial fabric with evenly distributed breathable pores on its surface. The natural fiber antibacterial fabric can be cotton, ramie, linen, hemp, or bamboo fiber.

[0036] In this embodiment: the fabric layer 102 is made of bamboo fiber antibacterial fabric, a natural fiber. The surface is processed with laser perforation to create uniform ventilation holes with a diameter of 0.5mm and a spacing of 2mm. The bamboo fiber antibacterial fabric has natural antibacterial properties, which, together with the ventilation holes, form a dual effect of active antibacterial and rapid air ventilation, reducing bacterial growth and stuffiness. The ventilation holes accelerate air convection, solving the problem of insufficient breathability and sweating in traditional seat cushions, and improving the comfort of sitting for a long time.

[0037] It should be noted that: when fabric layer 102 is made of cotton or ramie, it is naturally soft and suitable for sensitive skin, reducing the stuffiness during summer use, and is suitable for ordinary household cushions. When fabric layer 102 is made of hemp, it inhibits the growth of bacteria on the cushion and is suitable for use in humid areas. When fabric layer 102 is made of linen, it absorbs odors and is suitable for outdoor seat cushions, reducing sweat odor residue. The fabric can be selected according to actual usage needs.

[0038] Furthermore;

[0039] In an optional embodiment, the outer surfaces of both sets of fabric layers 102 are provided with anti-slip textures, which are diamond patterns or wave patterns.

[0040] In this embodiment: the diamond pattern increases the friction between the human body and the seat cushion, preventing the body from sliding when sitting for a long time; the wave pattern enhances the fit between the seat cushion and the seat surface, preventing the seat cushion from shifting when the vehicle is moving or when getting up; the textured structure can also form tiny air cavities on the contact surface, assisting ventilation and relieving local pressure.

[0041] Furthermore;

[0042] In an optional embodiment, the edging 103 is fixed with high-strength polyester sewing thread through a double-line overlock process, and the inner side of the edging 103 is provided with elastic ribs, which are made of thermoplastic polyurethane elastomer material.

[0043] In this embodiment: high-strength polyester yarn and double-line overlocking enhance the tear resistance of the edges, solving the problem of easy unraveling of traditional 103 edge binding. The thermoplastic polyurethane elastomer material provides continuous rebound force, preventing the edges of the cushion from collapsing due to long-term pressure and extending its service life.

[0044] Furthermore;

[0045] In an optional embodiment, the Ula grass filling felt layer 101 is mixed with 5%-10% of its total mass of Artemisia argyi fiber, the Artemisia argyi fiber being 3-5 cm in length, and distributed with Ula grass fiber through a cross-laying process.

[0046] In this embodiment, Artemisia fiber is introduced on the basis of Ula grass fiber. The natural antibacterial and insect-repelling properties of Artemisia argyi and the breathability and warmth of Ula grass form a synergistic effect. The cross-laying process ensures that the two fibers are evenly mixed, which not only retains the core advantages of Ula grass, but also adds an environmentally friendly insect-repelling function. This solves the problem that traditional cushions are prone to attracting mosquitoes when used outdoors in summer. Moreover, the composite of the two natural fibers has no chemical additives, which is in line with the trend of green home furnishing.

[0047] Furthermore;

[0048] In an optional embodiment, a removable and washable zipper is provided on one side edge of the seat cushion, the length of which is 1 / 2 of the circumference of the seat cushion, and a waterproof and breathable membrane is provided between the fabric layer 102 and the Ula grass filling felt layer 101, the waterproof and breathable membrane being a polytetrafluoroethylene microporous membrane.

[0049] In this embodiment: the fabric layer 102 and the Ula grass filling felt layer 101 are separated and cleaned by a detachable and washable zipper, which solves the problem of the Ula grass filling felt layer 101 becoming damp and clumping when the traditional whole cushion is washed; the addition of polytetrafluoroethylene microporous membrane ensures normal ventilation of the air pores while blocking liquid from penetrating into the Ula grass filling felt layer 101, avoiding the mold growth of Ula grass fibers caused by beverage spills or sweat penetration, and taking into account both cleaning convenience and filling layer protection, breaking through the technical limitations of existing cushions that are breathable but not waterproof, or waterproof but not breathable.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
