[0006] The first support plate and the second support plate are provided with internal limiting openings for installing the outer support airbags.

[0007] A first air delivery nozzle connected to a central regulating air bag and a second air delivery nozzle connected to an outer supporting air bag are axially fixed at both ends of the top assembly shaft.

[0008] The top assembly shaft is a hollow structure, the central adjustment airbag is inserted into the top assembly shaft through a first connecting tube and is fixedly connected to the first air delivery nozzle, and the outer support airbag is inserted into the top assembly shaft through a second connecting tube and is fixedly connected to the second air delivery nozzle.

[0009] The first supporting plate and the second supporting plate have internal operation openings at their inner lower ends.

[0010] The outer supporting airbag is fixedly connected with the second air delivery nozzle through the second connecting pipe, passing through the inner limiting opening, the middle adjusting airbag and the inside of the top assembly shaft.

[0011] The beneficial effects of the utility model are:

[0012] (1) The inflatable back cushion with a foldable support mechanism of the utility model adopts a cardboard plus air bag design, which is not only convenient for storage and carrying, but also can improve the back support;

[0013] (2) By axially fixing a first air delivery nozzle connected to the middle adjustment airbag and a second air delivery nozzle connected to the outer support airbag at both ends of the top assembly shaft, air can be delivered to different airbags respectively, making the operation more convenient;

[0014] (3) The angles of the first support plate and the second support plate can be adjusted by the central adjustment airbag, and the comfort of the support surface can be improved by the outer support airbag;

[0015] (4) The central adjustment airbag and the outer support airbag can be fixedly connected through the second connecting pipe, thereby improving the connection firmness and stability between the airbag and the support plate and facilitating adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 and Figure 2An inflatable cushion with a foldable support mechanism is shown, comprising a first support plate 1 and a second support plate 2, the upper ends of the first support plate 1 and the second support plate 2 both having a top bent bracket 3 of an integral structure, the top bent brackets 3 on the first support plate 1 and the second support plate 2 are arranged in a staggered manner, the first support plate 1 and the second support plate 2 are movably assembled via a top assembly shaft 4 that passes through the top bent bracket 3, a central adjustment airbag 5 is arranged between the first support plate 1 and the second support plate 2, and outer support airbags 6 are installed on the outer sides of the first support plate 1 and the second support plate 2.

[0022] In order to facilitate internal connection and fixation, internal limiting openings 7 for installing the outer supporting airbags 6 are provided inside the first supporting backboard 1 and the second supporting backboard 2 .

[0023] In order to cooperate with the air guide on both sides and facilitate operation, the two ends of the top assembly shaft 4 are axially fixed with a first air delivery nozzle 8 connected to the central adjustment airbag 5 and a second air delivery nozzle 9 connected to the outer support airbag 6.

[0024] In order to facilitate internal connectivity, the top assembly shaft 4 is a hollow structure, the central adjustment airbag 5 is inserted into the top assembly shaft 4 through the first connecting tube 10 and is fixedly connected to the first air nozzle 8, and the outer support airbag 6 is inserted into the top assembly shaft 4 through the second connecting tube 11 and is fixedly connected to the second air nozzle 9.

[0025] In order to facilitate carrying, internal operation openings 12 are provided at the lower ends of the first supporting plate 1 and the second supporting plate 2 .
