[0031] Reference Figures 1-11 In a preferred embodiment of this utility model, an inflatable mattress for driver and passenger seats includes an integrated single-cavity irregular-shaped bottom inflatable mattress 1 and a separate fitted sheet 3. The outer perimeter of the single-cavity irregular-shaped bottom inflatable mattress 1 is connected to the fitted sheet 3 via a double-sided interlocking zipper 2. A 3D mesh mattress 23 is provided between the single-cavity irregular-shaped bottom inflatable mattress 1 and the fitted sheet 3 to enhance the support of this utility model. The integrated single-cavity irregular-shaped bottom inflatable mattress 1 is more convenient to inflate and deflate. The fitted sheet 3 adopts a separate design, allowing the single-cavity irregular-shaped bottom inflatable mattress 1 and the fitted sheet 3 to be separated and combined, facilitating cleaning and assembly. The fitted sheet 3 is composed of AB double-sided multi-layer knitted fiber fabric suitable for winter and summer. Specifically, the AB double sides of the fitted sheet 3 are a top layer 15 suitable for summer and a bottom layer 17 suitable for winter, respectively. A sandwich layer 16 is provided between the top layer 15 and the bottom layer 17. The top layer 15 is made of PE cooling ice silk fiber, the sandwich layer 16 is made of high-elastic fiber, and the bottom layer 17 is made of cotton fiber.

[0032] In this embodiment, the double-sided interlocking zipper 2 includes a single-cavity irregular-bottom inflatable bed chain 5 and a fitted sheet chain 6, which are respectively fixed on the single-cavity irregular-bottom inflatable bed 1 and the fitted sheet 3. The fitted sheet chain 6 includes an upper insert 7 and a lower insert 8 at both ends, which have the same structure. The single-cavity irregular-bottom inflatable bed chain 5 includes a pull head block 9 and a seat 10 at both ends. The pull head block 9 is provided with a stop tooth 11. Both the upper insert 7 and the lower insert 8 of the fitted sheet chain can be used in conjunction with the seat 10 of the single-cavity irregular-bottom inflatable bed.

[0033] Specifically, this utility model, through the design of the double-sided interlocking zipper 2, allows the fitted sheet 3 to be freely combined with the single-cavity irregular-bottom inflatable mattress 1. Furthermore, the fitted sheet 3 can be connected to the single-cavity irregular-bottom inflatable mattress 1 through the AB double-sided materials of different materials, so that either side of the fitted sheet 3 can come into contact with the user, making it suitable for use in both summer and winter, thus improving its practicality. In addition, the materials of the top layer 15, the bottom layer 17, and the interlayer 16 give the fitted sheet 3 the advantages of high breathability, high resilience, strong support, lightweight, easy washing, and environmentally friendly, non-toxic, and odorless properties.

[0034] In this embodiment, the bottom surface of the single-cavity irregular-bottom air mattress 1 is designed in a wave pattern to conform to the curve of the car seat. The wave-shaped bottom surface conforms to the curved surface of the car seat, making the single-cavity irregular-bottom air mattress 1 more stable when laid on the car seat and improving the utilization of interior space. Inflation / expansion nozzles 14 for inflation and deflation are respectively provided on the front side of the left end and the rear side of the right end of the single-cavity irregular-bottom air mattress 1. Figure 5 As shown in this embodiment, both sides of the inflation / deflation nozzles 14 can be individually inflated using external air pumps, and both sides can be inflated / deflated simultaneously. Compared with the existing single-sided inflation / deflation airbeds, the inflation / deflation efficiency of this utility model is higher, so that the single-cavity irregular bottom airbed 1 can be rolled up from both sides for storage. When rolling up from one side, there will be no situation where the air inside the airbed is not discharged from the other side, and it is more convenient to store and use.

[0035] Another embodiment of this utility model: A built-in air pump chamber is set at the left inflation / deflation nozzle 14, and the built-in air pump is used to inflate / exhale the left inflation / deflation nozzle 14, which is more convenient to operate and does not require carrying an external air pump.

[0036] It should be noted that the 3D mesh structure mattress 23, inflation and deflation nozzle 14, external air pump, and internal air pump / compartment of this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can flexibly select them as needed, and will not be described in detail here.

[0037] In this embodiment, the interior of the single-cavity irregular-bottom inflatable bed 1 is an inflatable cavity 13. Multiple sets of air cavity straps 12 of different heights are provided inside the inflatable cavity 13 for support and shaping. The upper and lower ends of the air cavity straps 12 are connected to the inner top and inner bottom of the single-cavity irregular-bottom inflatable bed 1, respectively. The front and rear sides of the air cavity straps 12 are not connected to the inner front and rear sides of the single-cavity irregular-bottom inflatable bed 1. The multiple air cavity straps 12 divide the inflatable cavity 13 into multiple separate inner cavities, and the multiple separate inner cavities are interconnected.

[0038] Furthermore, the single-cavity irregular-shaped bottom inflatable mattress 1 consists of a perimeter band, an air cushion top surface, and a wavy bottom curved surface. The perimeter band is made of a knitted composite TPU material with a high expansion coefficient. The high expansion coefficient of the knitted material allows the gas to expand outwards within the inflation cavity 13, enabling the inflatable mattress to fill the gaps in the inflated car seat and increase the product's stability. The air cushion top surface, the wavy bottom curved surface, and the air cavity strap 12 are all made of nylon composite TPU fabric with a thickness of 21 mils through high-frequency heat pressing. Most inflatable mattresses on the market use transparent or white 10-mil TPU film for their air cavity straps, which have a certain degree of elasticity. After inflation, this makes the product taller and occupies space inside the car. In contrast, the nylon composite TPU fabric with a thickness of 21 mils has less elasticity and is thicker, providing greater height and stronger support without taking up too much space on the car seat.

[0039] Furthermore, the wavy bottom surface includes a leg wave zone 20, a waist support zone 21, and a shoulder zone 22, based on the pressure differences in the waist and legs of the human body.

[0040] Furthermore, both the single-cavity irregular-shaped bottom air bed 1 and the air cavity pull strap 12 are made of 40D nylon composite TPU fabric with a thickness of 21 filaments, which are high-frequency hot-pressed together.

[0041] In this embodiment, the bottom surface of the single-cavity irregular bottom air bed 1 is provided with Velcro, and the single-cavity irregular bottom air bed 1 is connected to the storage bag 18 through Velcro. The bottom surface of the single-cavity irregular bottom air bed 1 is provided with the rough side 4 of Velcro, and the storage bag 18 is provided with the hook side 19 of Velcro.

[0042] Specifically, preferably, the single-cavity irregular-shaped bottom inflatable bed 1 is 1.8*0.6m. When the single-cavity irregular-shaped bottom inflatable bed 1 is vented from both sides for storage, the rough side 4 with Velcro is attached to the storage bag 18 and left in place. Then, it is folded once → folded once along the length direction (1.8m → 0.9m), folded twice → folded 0.3m along the length direction, and folded three times → folded along the length direction (0.6m → 0.3m). After this, it is placed in the storage bag 18. Then, the storage bag 18 is stored using a common zipper in the prior art, so that the single-cavity irregular-shaped bottom inflatable bed 1 and the storage bag 18 can be stored together as one unit, making it easy to store and convenient to keep.

[0043] Scope of application of this utility model: This utility model is applicable to vehicles with detachable headrests and front seats that fold down to form a flat surface with the rear seats. Specific models include: Li Auto L6 / L7 / L8 / L9, Wenjie M7 / M9, XPeng G6 / P5 / G9, Ledao, Trumpchi M8 / E9 / GS8 / M6pro, Jike 7X, Weipai Lanshan, Honda Elysion / URV / Avancier / Lingpai / Envix, Aion Y / Yplus / s / v Tyrannosaurus / Honda Z03, Hongqi E-QM5, Voyah Chasing Light / Zhiyin, Pajero V93, Wuling Xingguang, Formula Leopard 5, Deep Blue G318, Nissan Teana, etc.

[0044] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0045] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
