Technical Field
[0001] The utility model relates to the technical field of leisure chair cushions, and more specifically to an inflatable cushion. Background Art
[0002] In modern life, inflatable mattresses are widely used in outdoor activities, camping, medical care, temporary accommodation and other occasions as a portable rest and sleep solution. However, traditional inflatable mattress technology faces many challenges and limitations. First of all, in terms of material selection, traditional inflatable mattresses mostly use single or simple composite materials. Although these materials excel in lightness and portability, they are often unsatisfactory in terms of durability, thermal insulation and support. For example, the materials used in some inflatable mattresses may wear out after long-term use, affecting their service life; at the same time, these materials may not effectively isolate the outside temperature, causing users to feel uncomfortable in cold environments.
[0003] Secondly, in terms of structural design, the support structure of traditional inflatable cushions is usually relatively simple and may not provide uniform support, which not only affects the user's comfort, but may also cause certain parts of the body to bear excessive pressure, which may cause physical discomfort after long-term use. In addition, traditional inflatable cushions often ignore the principles of ergonomics when designing, and fail to fully consider the different support requirements of different parts of the human body.
[0004] Furthermore, as people's requirements for quality of life improve, higher requirements are placed on the functionality and comfort of inflatable cushions. Users not only need a cushion that can provide basic support, but also expect it to maintain a stable temperature in various environments, provide uniform and lasting support, and have a certain degree of wear resistance and durability.

This structural design makes the inflatable cushion more wear-resistant and extends the service life of the product. The inflatable cushion of the present invention adopts a multi-layer composite material structure, including a sample cloth, TPU and a reflective film. This combination not only improves the overall performance of the inflatable cushion, but also allows the product to maintain advantages in weight and portability. The needle-punched quilt is wrapped with reflective film on the top and bottom. This design enhances the overall thermal insulation effect of the inflatable mattress, allowing users to enjoy a warm and comfortable sleeping environment in all climate conditions. The setting of the concave point is not only beautiful, but also increases the functionality of the inflatable mattress. By forming an independent inflatable chamber, the support performance and thermal insulation effect of the inflatable mattress are further improved.
[0013] In summary, the inflatable cushion of the present invention provides a comfortable and practical solution through its innovative design and material selection, which meets the multi-faceted needs of modern users for inflatable cushions and can provide excellent performance and experience both in outdoor activities and in daily use.

[0020] Please refer to the attached Figure 1-4 , is an inflatable cushion disclosed by the utility model.
[0021] The utility model includes the following structure:
[0022] The sample cloth 1 is the outermost layer of the inflatable cushion and directly contacts the user's body. It is located at the top layer of the entire structure and provides the main surface material. It has the characteristics of wear resistance, waterproofness and easy cleaning. The sample cloth 1 in the utility model is made of 40D nylon cloth, which has good wear resistance and strength and is suitable for outdoor use. The surface of the nylon cloth is smooth, easy to clean, and has a certain waterproof performance. The sample cloth 1 is also provided with an inflation hole, and the inflation plug 7 is buckled on the inflation hole.
[0023] The TPU2 (thermoplastic polyurethane) layer is located below the sample fabric 1 and is tightly connected to the sample fabric 1 through thermal bonding technology. This connection method ensures a firm bond between TPU2 and the sample fabric 1, while improving the hardness and strength of the sample fabric 1, and increasing the overall durability of the inflatable cushion. This bonding method ensures a tight bond between TPU2 and the nylon cloth, while improving the hardness and strength of the surface of the sample fabric 1, and increasing the overall durability of the inflatable cushion.
[0024] Reflective film 3: Reflective film 3 is located below the TPU2 layer and laid on the bottom of TPU2. The main function of reflective film 3 is to reflect the heat from the inflatable cushion and help keep the surface of the cushion cool. Reflective film 3 is fixed to the TPU2 layer by heat pressing or other appropriate means to ensure that it is flat and wrinkle-free to ensure the best reflection effect. It is particularly suitable for use in hot climates or environments with direct sunlight. During the laying process of reflective film 3, it is necessary to ensure that it is flat and wrinkle-free to ensure the best reflection effect.
[0025] Needle-punched cotton 4: The needle-punched cotton 4 is wrapped by the reflective film 3 and TPU 2 in two layers, forming a middle insulation layer. This structural design enhances the insulation effect of the inflatable cushion while providing a soft sense of support. The needle-punched cotton 4 has good thermal insulation performance and softness, and can provide a comfortable sense of support. During the manufacturing process, the needle-punched cotton 4 needs to be accurately placed on the reflective film 3 and fixed in place by heat pressing or other appropriate methods.
[0026] The sample fabric 1, TPU 2, and reflective film 3 form a symmetrical structure, wrapping the needle-punched cotton 4 to form a complete seven-layer structure. It not only ensures the durability and comfort of the inflatable cushion, but also achieves the effects of heat preservation, support and heat reflection through the different functions of each layer of material.
[0027] The surface of the inflatable cushion is provided with a number of depressions 5, which correspond one to another up and down to form independent inflatable chambers 6. Each inflatable chamber 6 is supported by an internal drawstring 51 to ensure uniform distribution of overall force. The design of the drawstring 51 takes into account the shape and size of the inflatable chamber 6 to ensure that stable support can be provided after inflation. This design not only improves the support performance of the inflatable cushion, but also enhances the stability and comfort of the cushion through the independent structure of the inflatable chamber 6.
[0028] During the manufacturing process of the inflatable cushion, TPU2 is first fixed to the nylon cloth through thermal bonding technology to ensure a strong bond between the two. The temperature and time of thermal bonding need to be precisely controlled to avoid overheating of the material or loose bonding. Next, the reflective film 3 is laid on the bottom of TPU2 and ensured to be flat and wrinkle-free. Finally, the needle-punched cotton 4 is placed on the reflective film 3 and fixed in place by heat pressing or other appropriate means to form a complete seven-layer structure. The entire manufacturing process requires strict quality control to ensure the correct installation of each component and the stability of the overall structure.
[0029] During use, the user can inflate the air chamber 6 of the air cushion by an air pump or other inflatable tools until the desired hardness and support are achieved. The concave point design of the air cushion allows the user to adjust the amount of inflation according to personal preference to obtain the best use experience. During the inflation process, the user should be careful not to over-inflate to avoid damage to the air cushion. After use, the user can easily store the inflatable cushion by releasing the air in the inflatable chamber 6 for easy carrying and storage.
