Description

Technical Field

[0001] This utility model relates to a seat cushion, and more particularly to an antibacterial and comfortable car seat cushion. Background Technology

[0002] Car seat cushions play a vital role in automotive accessories, providing comfort for passengers and protecting the seats. Common materials for car seat cushions include cotton, leather, linen, and plush. Cotton cushions are soft, comfortable, and breathable, suitable for all seasons, but easily attract stains. Leather cushions are easy to clean, but their poor breathability can make them feel stuffy in hot summers. Linen cushions are highly breathable and absorbent, keeping you cool in summer, but they are not as soft or comfortable. Plush cushions provide excellent warmth in winter but are unsuitable for summer use and tend to trap dirt, resulting in high cleaning costs.

[0003] Therefore, the comfort of existing car seat cushions needs to be improved. Some car seat cushions have certain seasonal limitations. In high temperatures, the seat cushion temperature is high, and the human body is prone to feeling stuffy and sweaty, and the seat cushion is prone to bacterial growth. In low temperatures, the seat cushion temperature is low, and the human body's user experience is poor. Utility Model Content

[0004] The purpose of this invention is to provide an antibacterial and comfortable car seat cushion. This invention features variable temperature operation, comfortable use, antibacterial properties, and durability.

[0005] The technical solution of this utility model is as follows: An antibacterial and comfortable car seat cushion, comprising a seat cushion body, the seat cushion body comprising a breathable surface layer, a first support layer, a second support layer and an anti-slip bottom layer, the surface of the breathable surface layer being provided with an anti-ultraviolet antibacterial layer, the bottom surface of the breathable surface layer being provided with a hydrophobic antibacterial coating, the first support layer and the second support layer being uniformly provided with breathable holes, the first support layer being more flexible than the second support layer, a phase change layer being provided between the first support layer and the second support layer, the phase change layer comprising alternating first phase change strips and second phase change strips, the phase change temperature of the first phase change strips being different from the phase change temperature of the second phase change strips.

[0006] The aforementioned antibacterial and comfortable car seat cushion also includes a pair of detachable limiting components connected to both sides of the surface of the seat cushion body.

For example, they can refer to a fixed connection, a detachable connection, a hinged connection, a rotating connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Example:

[0024] like Figures 1-3 As shown, an antibacterial and comfortable car seat cushion includes a seat cushion body 8. The seat cushion body 8 includes a breathable surface layer 1, a first support layer 2, a second support layer 3, and an anti-slip bottom layer 4. The surface of the breathable surface layer 1 is provided with an anti-ultraviolet antibacterial layer 11, and the bottom surface of the breathable surface layer 1 is provided with a hydrophobic antibacterial coating 12. The first support layer 2 and the second support layer 3 are uniformly provided with breathable holes. The flexibility of the first support layer 2 is greater than that of the second support layer 3. A phase change layer 5 is provided between the first support layer 2 and the second support layer 3. The phase change layer 5 includes alternating first phase change strips 51 and second phase change strips 52. The phase change temperature of the first phase change strip 51 is different from that of the second phase change strip 52.

[0025] This invention reduces the damage of ultraviolet rays to the cushion by using the anti-ultraviolet antibacterial layer 11, which reduces bacterial growth and improves the cushion's durability; the breathable surface layer 1 is in contact with the human body, providing good breathability and high comfort; and the hydrophobic antibacterial coating 12 prevents human sweat from penetrating into the cushion, reducing bacterial growth inside the cushion and improving the safety and health of using the cushion.

[0026] The first support layer 2 in this invention has high flexibility and elasticity, which can adapt well to the curves of the human body and effectively relieve the pressure on the buttocks caused by maintaining the same posture for a long time, thereby improving the comfort of sitting. A phase change layer 5 is set between the first support layer 2 and the second support layer 3, which can automatically adjust the temperature of the cushion according to temperature changes. Breathing holes are set on the first support layer 2 and the second support layer 3 to increase air circulation and ensure good breathability and heat transfer. The second support layer 3 has low flexibility and plays a role in stabilizing the shape of the deformed phase change layer 5, keeping it flat and improving the comfort of using the cushion.

[0027] The phase change material in the first phase change strip 51 and the second phase change strip 52 can be at least one of phase change microcapsules, shaped phase change materials, organic phase change materials, and inorganic phase change materials; specifically, it can be one or more of alkanes, fatty acids, esters, fatty alcohols, and water. When the ambient temperature around the phase change material rises, the phase change material absorbs heat and lowers the cushion temperature. When the ambient temperature drops, the phase change material begins to release the previously stored heat, improving its heat retention.

[0028] The phase change temperature of the first phase change strip 51 is different from that of the second phase change strip 52. This allows the seat cushion to adjust its temperature by having the first phase change strip 51 and the second phase change strip 52 undergo phase changes separately at different temperatures. If the ambient temperature is between the phase change temperatures of the first phase change strip 51 and the second phase change strip 52, then only the first phase change strip 51 or the second phase change strip 52 needs to undergo a phase change to meet the requirements. If the ambient temperature is higher or lower than the phase change temperatures of the first phase change strip 51 and the second phase change strip 52, then the first phase change strip 51 and the second phase change strip 52 undergo phase changes simultaneously, thus expanding the temperature adjustment range and accelerating the rate of temperature change of the seat cushion.

[0029] This invention also includes a pair of detachable limiting components 6 connected to both sides of the surface of the seat body 8. The limiting components 6 can better restrict the sitting posture and range of motion of the human body, reduce the phenomenon of the human body sliding or deviating, prevent secondary injury caused by inertia during collision, and improve safety.

[0030] The limiting component 6 includes an outer casing 61, inside which are a fixed strip 62 and a flexible movable strip 63. A buffer spring 64 connects the fixed strip 62 and the movable strip 63. The movable strip 63 is located on the side closer to the human body. The movable strip 63 is made of flexible material and, through the buffer spring 64, can buffer the impact force when the human body collides with the movable strip 63, reducing injury to the human body.

[0031] The fixing strip 62 has an installation strip 65 extending from the outer sleeve 61. The installation strip 65 has several transverse connecting holes 66, and a pin 67 or bolt is installed in each connecting hole 66. The side of the seat cushion body 8 has a mounting seat 68, which has several longitudinal mounting holes 681 for inserting the pin 67. The mounting seat 68 also has a restraint strap 69 for binding with the car seat. The seat cushion body 8 is fixed to the seat by the restraint strap 69. The limiting component 6 is fixed to the seat cushion by connecting the installation strip 65 to the mounting seat 68. By connecting different connecting holes 66 on the installation strip 65 to different mounting holes 681 on the mounting seat 68, the position of the limiting component 6 on the seat cushion can be adjusted to better match the sitting posture of different people.

[0032] The first support layer 2 and the second support layer 3 are made of memory foam, latex or gel.

[0033] The breathable surface layer 1 is made of composite yarn, which includes elastic fibers 71, with moisture-wicking fibers 72 and cotton fibers 73 spirally wound around the outer surface of the elastic fibers 71. The breathable surface layer 1 is both elastic, allowing it to change shape with the first support layer 2 to better conform to the curves of the human body, and absorbs and wicks away sweat through the moisture-wicking fibers 72 and cotton fibers 73, reducing bacterial growth.

[0034] The UV-resistant and antibacterial layer 11 is made of nano-TiO₂. 2- SiO2 coating or nano zinc oxide coating.

[0035] The hydrophobic antibacterial coating 12 is a chitosan-TiO2-Ag coating.

[0036] The parts of this utility model not described in detail are existing technologies and therefore will not be specifically described here.
