[0039] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] The pneumatic wing support device 1000 of the present invention can be installed on the wing of a seat, such as the wing of a vehicle seat, to provide lateral support. Figure 1 and Figure 6 The pneumatic wing support device 1000 includes a support plate 1, a cover plate 2 and a support airbag 3.

[0041] The support plate 1 is used to support and install the support airbag 3, and to connect the pneumatic wing support device 1000 with the seat. The cover plate 2 is movably installed on the support plate 1 and can be turned over relative to the support plate 1. The support airbag 3 is installed between the support plate 1 and the cover plate 2. The support airbag 3 is used to provide support force when inflated, and the support airbag 3 can push the cover plate 2 to turn over relative to the support plate 1 when inflated. The cover plate 2 is used to provide a larger support area, for example, the cover plate 2 has a flat or smooth large surface area to improve the comfort of the wing support.

[0042] In some embodiments, when in use, the pneumatic wing support device 1000 includes an inflated state and a non-inflated state. When in the inflated state, the support airbag 3 inflates and expands to push the cover plate 2 from the initial position to the support position, and the support airbag 3 is maintained in the inflated state to maintain the cover plate 2 in the support position; when the support airbag 3 is deflated and in the non-inflated state, the support airbag 3 is deflated and the volume is reduced, and the cover plate 2 loses the support of the support airbag 3 and flips back, and falls back to the initial position after the support airbag 3 is completely deflated.

[0043] In some embodiments, the support plate 1 has a connection groove 11 that is recessed relative to the surface of the support plate 1, and a pivot portion 12 is disposed in the connection groove 11.
