Technical Field

[0001] This utility model relates to the field of seat manufacturing, and more particularly to a seat and a vehicle having the same. Background Technology

[0002] In existing technologies, car seat cushions are all made of urethane polymer foam and molded in a mold. Due to the insufficient breathability of polyurethane foam, moisture may be retained in humid environments. In addition, seat cushions made from a single type of urethane polymer foam have poor support, wrapping, and comfort. Furthermore, polyurethane foam is generally manufactured by mixing polyols, isocyanates, and other components. The chemical reactions involved release carbon dioxide to form the foam. Because of the large amount of carbon dioxide released, it affects the ecological environment and contributes to global warming. Moreover, polyurethane foam is difficult to recycle and has high manufacturing costs. Utility Model Content

The cover is disposed on the outer surface of the seat, the support frame is disposed at the bottom of the seat, and the foam pad is disposed between the cover and the support frame. The foam pad has a layered structure of at least two layers, and the density of the foam pad gradually decreases from bottom to top. At least one layer of the foam pad includes a three-dimensional winding of continuous thermoplastic fibers.

[0005] Furthermore, the density of the foam pad is 40 kg / m³. 3 -60 kg / m 3 .

[0006] Furthermore, the continuous thermoplastic fiber comprises at least 95% polyethylene by weight and 2%-3% polyolefin elastomer by weight.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] In the description of this utility model, it should be noted that the orientation or positional relationship indicated in this description is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the parts or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Please see Figure 1-3 This utility model provides a seat 10, including a cover 11, a foam pad 12, a support frame 13, and a fan 14. The cover 11 is disposed on the outer surface of the seat 10, the support frame 13 is disposed at the bottom of the seat 10, and the foam pad 12 is disposed between the cover 11 and the support frame 13. The foam pad 12 has at least two layers and its density gradually decreases from bottom to top. At least one layer of the foam pad 12 includes a three-dimensional wound of continuous thermoplastic fibers. The fan 14 is disposed on the support frame 13 and is connected to the foam pad 12 through an air duct 15. By using double or multiple layers of foam pads 12 with different densities, and by using a three-dimensional wound of continuous thermoplastic fibers, this utility model not only improves the breathability of the seat 10 but also further enhances its support, wrapping, and comfort.

[0023] Furthermore, the seat provided by this utility model adopts a foam pad 12 with at least two layers, including a multi-layer structure with two or more layers. The density of the foam pad 12 gradually decreases from bottom to top. Since the upper part of the foam pad 12 is closer to the passenger's buttocks and needs to bear the weight of the passenger, the hardness of the upper part of the foam pad 12 needs to be greater than that of the lower part of the foam pad 12. Since the lower part of the foam pad 12 is closer to the air duct 15, it is necessary to ensure the breathability of the foam pad 12. Therefore, a multi-layer structure of foam pad 12 is adopted, and the density of the foam pad 12 gradually decreases from bottom to top. The higher the density of the foam pad 12, the greater the hardness. Conversely, the lower the density, the lower the hardness and the better the breathability. Therefore, compared with the foam pad 12 with a single layer structure and a single density in the prior art, the foam pad 12 in this utility model can not only ensure the breathability of the seat 10, but also meet the support and comfort of the seat 10.

[0024] Specifically, based on experimental research, the density is 40 kg / m³. 3 -60 kg / m 3The foam pad 12 can simultaneously meet the requirements of support, comfort, and breathability of the seat 10. Therefore, the density of the foam pad 12 can be selected within the range of 40 kg / m³. 3 -60 kg / m 3 Furthermore, since experimental research has shown that the uppermost structure, which accounts for 20%-40% of the total thickness of the foam pad 12, can simultaneously meet the requirements of support and comfort of the seat 10, in the multi-layer foam pad 12 structure, the uppermost foam pad 12 structure accounts for 20%-40% of the total thickness of the foam pad 12, preferably 25%-35%.

[0025] Furthermore, the foam pad 12 includes a three-dimensional winding of continuous thermoplastic fibers. These continuous thermoplastic fibers are hollow fibers and / or dense fibers with a diameter between 0.2 mm and 2 mm, preferably between 0.3 mm and 1.5 mm. The three-dimensional winding of the continuous thermoplastic fibers is achieved through physical winding, which can be accomplished at a nozzle with a diameter of 0.2 mm to 2 mm. It should be noted that the specific manufacturing process of the three-dimensional winding of the continuous thermoplastic fibers can be found in existing technology and will not be elaborated here. The continuous thermoplastic fiber is a thermoplastic polymer, its components including at least 95% polyethylene by weight and 2%-3% polyolefin elastomer by weight. The polyethylene, polyolefin elastomer, and other compounds together constitute the continuous thermoplastic fiber. Using polyethylene as the thermoplastic polymer material achieves cost reduction. Compared to existing foam pads made entirely of polyurethane foam, the foam pad 12 of this invention, made of continuous thermoplastic fibers, is not only recyclable but also produces less carbon dioxide emissions during its manufacturing process, thus protecting the ecological environment. Furthermore, the foam pad 12 made of continuous thermoplastic fibers is much lighter than that made entirely of polyurethane foam. Most importantly, the foam pad 12 made of continuous thermoplastic fibers is more breathable, allowing more air and moisture to pass through, thus achieving seat ventilation. The air generated by the fan 14 enters the foam pad 12 through the air duct 15 and then the cover 11, achieving seat ventilation. In contrast, existing foam pads made entirely of polyurethane foam require air ducts in the foam pad 12 to achieve ventilation, reducing the manufacturing cost of the seat 10 and simplifying the manufacturing process. It should be noted that the air duct 15 is located between the fan 14 and the foam pad 12, with its top connected to the foam pad and its bottom connected to the air outlet of the fan 14.

[0026] In one embodiment of this utility model, the foam pad 12 has a two-layer structure, comprising an upper foam pad and a lower foam pad, wherein the density of the upper foam pad is 40 kg / m³. 3 -50 kg / m3 The density of the lower foam pad is 50 kg / m³. 3 -60kg / m 3 .

[0027] In one embodiment of this utility model, the upper foam pad is made of a three-dimensional winding of continuous thermoplastic fibers, and the lower foam pad is also made of a three-dimensional winding of continuous thermoplastic fibers. Compared with the foam pads in the prior art that are made entirely of polyurethane foam, the foam pad 12 in this embodiment can not only further improve the support, wrapping and comfort of the seat 10, but also improve the breathability of the seat 10.

[0028] In one embodiment of this utility model, the upper foam pad is made of polyurethane foam, and the lower foam pad is made of a three-dimensional winding of continuous thermoplastic fibers. A ventilation groove is provided on the upper foam pad, which is vertically arranged and connected to the air duct 15. Compared with the foam pads in the prior art that are made entirely of polyurethane foam, the foam pad 12 in this embodiment can further improve the support, wrapping and comfort of the seat 10, and can also improve the breathability of the seat 10. However, compared with the foam pad 12 made of three-dimensional winding of continuous thermoplastic fibers for both the upper and lower layers, the effect is slightly worse.

[0029] In one embodiment of this utility model, the upper foam pad is made of a three-dimensional winding of continuous thermoplastic fibers, and the lower foam pad is made of polyurethane foam. A ventilation groove is provided on the upper foam pad, which is vertically arranged and connected to the air duct 15. Compared with the foam pads in the prior art that are made entirely of polyurethane foam, the foam pad 12 in this embodiment can further improve the support, wrapping and comfort of the seat 10, and can also improve the breathability of the seat 10. However, compared with the foam pad 12 made of three-dimensional winding of continuous thermoplastic fibers for both the upper and lower layers, the effect is slightly worse.

[0030] As described above, the seat provided by this utility model uses double or multiple layers of foam pads 12 with different densities. The foam pads 12 are made of three-dimensional winding of continuous thermoplastic fibers. Compared with the foam pads in the prior art that are made entirely of polyurethane foam, this not only further improves the support, wrapping, and comfort of the seat 10, but also improves the breathability of the seat 10. Moreover, the continuous thermoplastic fiber component uses polyethylene material, which accounts for at least 95% by weight, thus achieving the goal of cost reduction. In addition, the foam pads 12 made of continuous thermoplastic fibers can not only be recycled and reused, reducing manufacturing costs, but also generate less carbon dioxide emissions during their manufacturing process, thus protecting the ecological environment.

[0031] This utility model also provides a vehicle including the seat as described above. For other structures of the vehicle, please refer to the prior art, which will not be repeated here.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
