Description

Technical Field

[0001] The utility model relates to the technical field of seat cushions, in particular to a seat cushion for rail transportation with a cooling function. Background Art

[0002] Seat cushions are comfortable and decorative, often in square, round, or oval shapes. They're made of cotton, flannel, damask, nylon, or linen, with memory foam being the most comfortable. Memory foam boasts the following characteristics: impact absorption; ergonomic design; memory deformation; antibacterial and mite-resistant; and breathable and moisture-wicking.

[0003] With the improvement of living standards, people travel more conveniently. When the surface temperature of rail transit seats is high, people feel less comfortable sitting in the seats. However, most seat cushions on the market do not have the function of cooling and ventilation. For this reason, we propose a rail transit seat cushion with cooling function. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a rail transit seat cushion with a cooling function. By arranging a checkered ice bag on the inner side of the seat cushion main body, the cooling effect of the seat cushion main body is better. The independent checkered ice bag has better support and wrapping properties, is durable and not easily damaged. By arranging breathable memory cotton on the inner side of the seat cushion main body, the breathable memory cotton has memory deformation and good resilience, which effectively reduces the load-bearing deformation and damage of the checkered ice bag, making it more comfortable for people to sit on the surface of the seat cushion main body. By arranging a gel base pad at the bottom end of the seat cushion main body, a ventilation and air permeable space is provided at the bottom end of the seat cushion main body. At the same time, the friction at the bottom end of the gel base pad is increased to play an anti-slip role.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a rail transit seat cushion with a cooling function, comprising a seat cushion main body, the seat cushion main body being composed of a checkered ice bag, a gel base pad, a cloth cover, a breathable memory foam, and a PVC composite cloth layer. A memory foam protrusion is formed on the surface of the PVC composite cloth layer at the top of the cloth cover, and a checkered ice bag is evenly laid on the inside of the cloth cover. The checkered ice bag is located at a position corresponding to the bottom end of the memory foam protrusion. The surface of the cloth cover between two checkered ice bags is separated by pressing and sewing. A gel base pad is pasted on the bottom end of the cloth cover, the breathable memory foam is at the top end of the cloth cover, and a PVC composite cloth layer is provided on the surface of the breathable memory foam. The cloth cover, breathable memory foam, and PVC composite cloth layer are fixed by pressing and sewing at a three-dimensional annular pressing position. A thickened edging strip is provided on the periphery of the seat cushion main body, and the thickened edging strip is fixed to the seat cushion main body by pressing and sewing.

[0006] As an optimal technical solution of the present invention, the surfaces of the four sides of the cloth cover on the back of the seat cushion body are sewn with widened sides, two metal rings are installed on the surface of the widened sides, and straps are provided on the inner sides of the metal rings. A Velcro B surface is sewn on one side of the bottom end of the widened side, and a Velcro A surface is sewn on the other side of the bottom end of the widened side, and the Velcro A surface corresponds to the Velcro B surface in position.

[0007] As a preferred technical solution of the present invention, the gel base pad is integrally formed by a plurality of square cross gel blocks.

[0008] As a preferred technical solution of the present invention, a Velcro position is provided at one end of the strap close to the metal ring.

[0009] As a preferred technical solution of the present invention, the inner side of the grid ice bag is filled with ice crystal material.

[0010] As a preferred technical solution of the present invention, the surface of the PVC composite cloth layer is printed with patterns.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By arranging a checkered ice bag on the inside of the seat cushion body, the seat cushion body has a better cooling effect. The independent checkered ice bag has better support and wrapping properties, is durable and not easy to damage. By arranging a breathable memory foam on the inside of the seat cushion body, the breathable memory foam has memory deformation and good resilience, which effectively reduces the load-bearing deformation and damage of the checkered ice bag. People sit more comfortably on the surface of the seat cushion body. By arranging a gel base pad at the bottom of the seat cushion body, the bottom of the seat cushion body has a ventilation and breathable space. At the same time, the bottom of the gel base pad increases friction to play an anti-slip role.

[0013] 2. Through the combination of widened sides, metal rings and straps, the main body of the seat cushion can be quickly fixed to the seat surface. Through the combination of Velcro A side and Velcro B side, the main body of the seat cushion can be spliced ​​into the required size according to people's needs. At the same time, the widened sides can be stored and invisible, making the surface of the main body of the seat cushion more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS
