[0030] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0031] See also Figures 1 to 6 As shown, the present invention provides an airbag unit 100 for a mattress and an airbag mattress incorporating the same. The airbag unit 100 includes an airbag body 1 and a support plate 2 connected to the airbag body 1. The airbag body 1 has an inflation cavity 13. After inflation within the inflation cavity 13, the airbag body 1 expands, and its load-bearing surface 131, which is an outwardly convex surface, is provided. After the airbag body 1 expands, the support plate 2 covers the outwardly convex load-bearing surface 131 of the airbag body 1.

[0032] See also Figures 1 to 3 As shown, in this embodiment, the airbag unit 100 is in the shape of a long strip. The airbag body 1 includes at least one airbag column 10, and the airbag column 10 includes two walls, namely a first wall 11 and a second wall 12. The peripheral edges of the two walls 11 and 12 are sealed together to form a sealing edge 14, and an inflation cavity 13 is formed between the two walls 11 and 12. Please refer to Figure 4 and Figure 5 As shown, when the inflation chamber 13 is uninflated, the first wall 11 and the second wall 12 are flat and abut against each other. When the inflation chamber 13 is inflated, the first and second walls 11, 12 of the airbag column 10 bulge outward, forming curved convex surfaces with a central bulge and two side sealing edges 14 connecting them. The inflated airbag column 10 is rod-shaped, with a fusiform or elliptical cross-section. In this embodiment, the airbag body 1 comprises two stacked airbag columns 10. The two airbag columns 10 are connected by a connecting port 130, which is provided on the adjacent walls of the two airbag columns 10. The distal walls of the two airbag columns 10 form a bearing surface 131. Specifically, when the airbag unit 100 is installed, one of the two bearing surfaces 131 forms an upward-facing surface for the user to sit or lie on, while the other forms a downward-facing surface for support on a support structure such as a bed frame. Each airbag column 10 is provided with an inflation port (not shown), located between two adjacent airbag columns 10. This allows for simultaneous inflation of the inflation cavity 13 through the inflation port, allowing both columns 10 to expand simultaneously. In other embodiments, depending on the required height of the airbag unit 100, the airbag body 1 may include a plurality of stacked airbag columns 10, each communicating with the other to form the inflation cavity 13.

[0033] Please continue reading Figures 1 to 3As shown, the airbag unit 100 also includes mounting bags 3 located on both sides of the airbag body 1. The mounting bags 3 are flat bag-shaped and have an opening at one end, so that the support plate 2 can be inserted into the mounting bag 3. The two sides of each mounting bag 3 are connected to the opposite sides of the airbag body 1 through a flexible member 4. In this embodiment, the support plate 2 is connected to the airbag body 1, which means that the support plate 2 is connected to the airbag body 1 through the mounting bag 3 and the flexible member 4. The flexible member 4 is a cloth belt, which is connected to the side edge of the mounting bag 3 and the sealing edge 14 of the airbag column 10. The flexible member 4 is an integral part with the mounting bag 3 and the airbag body 1. As shown Figure 4 and Figure 5 As shown, the flexible member 4 is deformable and connects the mounting bag 3 and the airbag body 1. When the airbag body 1 is not inflated, the mounting bag 3 and the support plate 2 mounted therein are in contact with each other, thereby reducing the height of the airbag unit 100 and facilitating storage and transportation. When the airbag body 1 is inflated, the flexible member 4 pulls the mounting bag 3 and the support plate 2 mounted therein on both sides to keep the support plate 2 stably positioned on the bearing surface 131 of the airbag body 1, so that the airbag body 1 is sandwiched between the two support plates 2. The support plates 2 may be thin plastic sheets or thin wooden sheets.

[0034] See also Figure 6 As shown, the present invention also provides an airbag mattress. The airbag mattress comprises a mounting base 5 and a plurality of airbag units 100 as described above, arranged in an array and mounted on the mounting base 5. The airbag mattress, assembled from the plurality of airbag units 100, has a smooth overall surface, enhancing the user experience.

[0035] From the above description of the specific embodiments, it can be seen that the airbag unit 100 provided by the present invention is provided with a support plate 2 connected to the airbag body 1, and the support plate 2 covers the convex bearing surface 131 formed after the airbag body 1 is inflated, so that the surface of the airbag unit 100 is flat. The overall surface of the airbag mattress spliced ​​together by the airbag units 100 is flat, which can enhance the user experience.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
