  • Patent number: 10555848
    Abstract: A seating system for a chair in the form of a deflatable cushion. The two-inch-thick cushion, divided into nine rectangular sections, will have an open-end casing comprised of viscoelastic foam. The air compressor, connected to the battery power source, shoots pressurized gas into a check valve and then into branched rubber tubings. The sequence of deflation is as follows: pressurized gas passes through the air compressor's plastic compartment, which encases antibacterial liquid that the gas can pass through before entering the check valve. Having exited the air compressor and entered the check valve, the valve will regulate the flow of air to the cushion based on synchronization with the compressor and electronic feedback from the application or manual control. Having entered the check valve, the pressurized, sanitary gas enters the rubber tubings and the porous rubber tubes' eight subsections. This will cause deflation of the cushion.
