Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.

Referring to fig. 1, 2 and 3, an embodiment of the chair cushion 100 of the present invention is suitable for a chair (not shown). The seat cushion 100 comprises a supporting seat 1, a supporting layer 2, a ventilating layer 3, and a covering layer 4.

The carrier 1 is made of, for example, plastic, and includes a bottom 11, a top 12, a front end 13, a rear end 14, and two sides 15. The side edges 15 are connected to the left and right sides of the front end 13 and the left and right sides of the rear end 14, respectively.

The supporting layer 2 is disposed on the top 12 of the carrying seat 1 and includes a first foam block 21, two second foam blocks 22 and a foam cushion 23. The first foam block 21, the second foam block 22 and the foam cushion 23 are all made of high-density foam, and are formed into a desired shape and thickness by, for example, cutting. The first foam piece 21 is, for example, substantially square, and the first foam piece 21 is, for example, adhesively secured to the top 12 adjacent to the middle of the front end 13. The second foam blocks 22 are oppositely arranged in the left-right direction, each second foam block 22 is, for example, substantially triangular, and each second foam block 22 is, for example, adhered to the top 12 and adjacent to the corresponding side 15 by an adhesive. The second foam piece 22 is spaced apart from the first foam piece 21. The top 12 of the carrier 1 has an exposed area 121 not covered by the first foam block 21 and the second foam block 22.

The shape of the foam pad body 23 is the same as that of the bearing seat 1. The foam pad 23 is adhered to the top of the first foam block 21 and the top of each of the second foam blocks 22 by an adhesive, for example, and the portion of the foam pad 23 not supported by the first foam block 21 and the second foam block 22 is recessed downward to the exposed area 121, so that the foam pad 23 is in a concave-convex shape. By the design of the first foam block 21 and the second foam block 22, the first foam block 21, the second foam block 22 and the foam cushion body 23 together form the shape of the support layer 2 with concave-convex fluctuation.

It should be noted that, the first foam block 21, the second foam block 22 and the foam pad 23 are cut and formed by cutting, and then stacked and fixed together, so that the supporting layer 2 does not need to be manufactured by a mold, thereby saving the mold opening cost and reducing the manufacturing cost of the supporting layer 2.

The shape of the breathable layer 3 is the same as that of the foam pad body 23 of the supporting layer 2, the breathable layer is arranged at the top of the foam pad body 23, and the breathable layer 3 is a three-dimensional breathable mesh fabric. Specifically, the breathable layer 3 of the present embodiment includes two mesh bodies 31 and a support body 32 disposed between the mesh bodies 31. Each of the net bodies 31 is formed with a plurality of net holes 311. The support 32 is formed of fibers connected between the net cloth bodies 31 and interwoven with each other. The mesh fabric 31 at the bottom end of the air permeable layer 3 is adhered to the top of the foam pad 23 by, for example, an adhesive, and the air permeable layer 3 has concave-convex fluctuation according to the shape of the foam pad 23. The breathable layer 3 can achieve high support and high breathability by the structural design of the mesh body 31 and the support body 32.

The coating layer 4 comprises a constant temperature cotton 41 and a surface cloth 42. The constant temperature cotton 41 covers the support layer 2 and the air permeable layer 3 and has a top covering portion 411 and a surrounding covering portion 412 extending downward from the outer periphery of the top covering portion 411. The top covering part 411 covers the top of the mesh body 31 at the top end of the air-permeable layer 3. The surrounding cover 412 covers the outer periphery of the support layer 2 and the outer periphery of the air-permeable layer 3. In this embodiment, the temperature-balancing cotton 41 has the function of temperature and humidity adjustment, and can achieve the effects of ventilation, dryness, coolness and no sultry. Furthermore, the foam of the constant temperature cotton 41 has a fine and soft texture and a soft and comfortable touch.

The cover cloth 42 is made of an elastic and air-permeable fabric, and covers the constant temperature cotton 41 and the bottom 11 of the carrier 1 near the outer periphery, and the cover cloth 42 is fixedly coupled to the bottom 11 by a plurality of nails (not shown), for example.

By the design of the first foam block 21 and the second foam block 22, the chair cushion 100 has a concave-convex shape corresponding to the supporting layer 2. Thereby, the covering property of the seat cushion 100 for covering the buttocks of the occupant can be increased. By the design of the foam cushion body 23, the support ability of the seat cushion 100 for supporting the buttocks of the occupant can be increased.

Since the air-permeable layer 3 has high support and air permeability, the air-permeable layer 3 is disposed between the support layer 2 and the top cover 411 of the cover layer 4, which can further increase the support of the seat cushion 100 for supporting the buttocks of the occupant, and can maintain good ventilation and heat dissipation effects between the support layer 2 and the cover layer 4, thereby effectively reducing the stuffiness feeling of the buttocks of the occupant after sitting for a long time. In addition, since the temperature-balancing cotton 41 has a good temperature and humidity adjusting function, the temperature and humidity of the air-permeable layer 3 and the surface cloth 42 can be adjusted simultaneously by the temperature-balancing cotton 41 disposed between the air-permeable layer 3 and the surface cloth 42, so as to rapidly balance the temperature of the seat cushion 100 and maintain the temperature in a specific region, thereby further improving the stuffiness feeling of the seated occupant after sitting for a long time. Further, since the temperature-maintaining cotton 41 is fine and soft in texture, the comfort of the seated person in the hip can be effectively enhanced.

In summary, the seat cushion 100 of the present embodiment can maintain good ventilation and heat dissipation effects between the supporting layer 2 and the covering layer 4 by the design of the ventilation layer 3, so as to effectively reduce the stuffiness feeling of the seat occupant after sitting for a long time. In addition, by means of the design of the constant temperature cotton 41 of the coating layer 4, the stuffiness feeling of the buttocks of the rider after sitting for a long time can be further improved, the comfort feeling of the buttocks of the rider during sitting can be effectively increased, and the purpose of the utility model can be really achieved.
