Title:
AUTOMATIC INFLATABLE CUSHION STRUCTURE HAVING COMPRESSION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2022/241674
Kind Code:
A1
Abstract:
An automatic inflatable cushion structure having a compression function, comprising an outer cover body (1), a space inside of the outer cover body (1) accommodating an inner filling body (2) that has a three-dimensional shape when in a normal state; the outer cover body (1) is provided with an air valve unit (12). When not in use, the inflatable cushion can be compressed to reduce the volume thereof; and when in use, external air can enter the inside of the outer cover body (1) and cooperate with the expansion and shape-restoration of the inner filling body (2), and an automatic inflation state can be achieved, thereby providing a soft support auxiliary function when a body is lying on their side, and also saving space when stored.
