[0031] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0032] See also Figures 1 to 8 As shown, the present invention provides an airbag assembly for a mattress, which is installed on a mounting base 5 of a mattress, and the airbag assembly includes an airbag unit 100 and a connector. The airbag unit 100 includes an airbag body 1 and a support plate 2, wherein the support plate 2 is connected to the airbag body 1, and the support plate 2 covers the bearing surface 131 of the airbag body 1 after the airbag body 1 is inflated. The connector includes a first connector 61 and a second connector 62, wherein the first connector 61 is arranged around the support plate 2 and fixed on the mounting base 5 to connect and fix the support plate 2 to the mounting base 5, and the second connector 62 is arranged around the support plate 2 and the airbag body 1 to connect and firmly connect the airbag body 1.

[0033] 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 and connected 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, in the inflatable cavity 13, the first wall surface 11 and the second wall surface 12 are flat and close to each other. When the inflatable cavity 13 is inflated, the first wall surface 11 and the second wall surface 12 of the airbag column 10 bulge to both sides, forming an arc-shaped convex surface with a convex middle and connected at the sealing edges 14 on both sides. The inflated airbag column 10 is rod-shaped, and its cross section is shuttle-shaped or elliptical. In this embodiment, the airbag body 1 includes two airbag columns 10 stacked up and down, and the two airbag columns 10 are connected through a connecting port 130. The connecting port 130 is opened on the wall surfaces of the two airbag columns 10 that are close to each other. The wall surfaces of the two airbag columns 10 that are far away from each other form a bearing surface 131, that is, when the airbag unit 100 is installed, one of the two bearing surfaces 131 constitutes a surface facing upward for the user to sit or lie down, and the other constitutes a surface facing downward for supporting on a support body such as a bed frame. The airbag column 10 is provided with an inflation port (not shown), and the inflation port is provided between two adjacent airbag columns 10. In this way, when the inflation cavity 13 is inflated through the inflation port, the gas can be simultaneously filled into the two airbag columns 10, so that the two airbag columns 10 can tend to expand synchronously. In other embodiments, according to the height requirement of the airbag unit 100, the airbag body 1 can also include more airbag columns 10 stacked and arranged, and the multiple airbag columns 10 are connected to form the inflation cavity 13.

[0034] Please continue reading Figures 1 to 3As shown, the airbag unit 100 further includes installation bags 3 located on both sides of the airbag body 1. The installation bags 3 are flat bag-shaped and have an opening at one end, so that the support plate 2 can be inserted into the installation bags 3. The two sides of each installation bag 3 are connected to the opposite sides of the airbag body 1 through the flexible member 4, and the support plate 2 is connected to the airbag body 1 through the installation bag 3 and the flexible member 4. The flexible member 4 is connected to the side edge of the installation bag 3 and the sealing edge 14 of the airbag column 10. The bottom of the installation bag 3 is not connected to the airbag body 1, and the installation bag 3 is only connected to the airbag body 1 through the flexible member 4 connected to the side, so that a gap for the first connecting member 61 and the second connecting member 61 to be installed is formed between the installation bag 3 and the airbag column 10 of the airbag body 1. In this embodiment, the two airbag columns 10 and the support plate 2 adjacent to them are connected through the flexible member 4. The flexible member 4 is a cloth belt, which is integrated with the installation bag 3 and the airbag body 1. The connection length of the flexible member 4 in the length direction of the airbag column 10 is smaller than the length of the airbag column 10, so as to form a clearance space for the first connecting member 61 and the second connecting member 61 to be installed on the side of the airbag unit 100. Figure 4 and Figure 5 As shown, the flexible member 4 can be deformed, and it connects the mounting bag 3 and the airbag body 1, so that when the airbag body 1 is not inflated, the mounting bag 3 and the support plate 2 installed therein are close to each other with the airbag body 1, so as to reduce the height of the airbag unit 100, and facilitate storage and transportation; and when the airbag body 1 is inflated, the mounting bag 3 and the support plate 2 installed therein are pulled on both sides to keep the support plate 2 stably located 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 plate 2 can be a plastic sheet or a wood sheet.

[0035] See also Figures 6 to 8As shown, for each airbag unit 100, the connecting member includes two first connecting members 61 and two second connecting members 62. The first connecting member 61 and the second connecting member 62 are both elastic bands, such as elastic bands. The first connecting member 61 is wound around the support plate 2 and fixed on the mounting base 5, and the second connecting member 62 is wound around the support plate 2 and the airbag body 1 and fixed on the mounting base 5, so as to connect and fix the support plate 2 and the airbag body 1 with the mounting base 5. The airbag body 1 inside the airbag unit 100 itself and the airbag unit 100 as a whole with the external mounting base 5 are connected and fixed by the first connecting member 61 and the second connecting member 62, so as to enhance the reliability of the fixing of the airbag unit 100. In this embodiment, the airbag body 1 includes two stacked airbag columns 10, and the second connecting member 62 is wound around the two airbag columns 10. The present invention further provides an airbag mattress, which includes a mounting base 5 and a plurality of airbag assemblies as described above, wherein the plurality of airbag assemblies are arranged in an array and mounted on the mounting base 5 .

[0036] From the above description of the specific embodiments, it can be known that the airbag assembly 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 load-bearing surface 131 of the airbag body 1 after inflation, so that the surface of the airbag unit 100 is flat; the airbag unit 100 is fixed by a first connecting member 61 and a second connecting member 62, and the first connecting member 61 connects and fixes the support plate 2 to the mounting base 5, and the second connecting member 62 is wrapped around the airbag body 1 to firmly connect the airbag body 1, so that the airbag body 1 inside the airbag unit 100 itself and the airbag unit 100 as a whole and the external mounting base 5 are connected and fixed, which can enhance the reliability of the fixation of the airbag unit 100 and improve the user experience.
