Abstract
An inflatable cushion that is orally inflatable using exhaled air. The inflatable cushion also can be inflated by breathing into an inflation chamber portion of the cushion and then squeezing the inflation chamber (e.g., with a user's hands and fingers), thereby increasing the pressure, to push additional air into the passages and channels to fill the seat cushion. A separate deflation chamber of the seat cushion can have a tubular check valve designed to be squeezed that opens the valve to deflate. The deflation chamber can be used to adjust the comfort of the inflatable cushion or to empty the inflatable cushion after use. The inflatable cushion can be made of thin plastic or similar material that is lightweight and can be folded, creating a structure that can be used several times before disposal.
Claims20
A cushion for a part of a body, to be placed between the part of the body and a hard surface, the cushion comprising:
- a main chamber that is inflatable;
- an inflation chamber separate from the main chamber and connected to the main chamber such that a compression action applied to an exterior of the inflation chamber when the inflation chamber is at least partially inflated causes an increase in pressure within the main chamber to facilitate inflation of the main chamber,
- wherein the inflation chamber is defined between a first one-way valve and a second one-way valve, and
- wherein the second one-way valve connects the inflation chamber to the main chamber, and
- a deflation chamber including a third one-way valve configured to release air from the main chamber.
An inflatable seat cushion comprising:
- a main chamber configured to provide cushioning to a user when inflated;
- and
- an inflation chamber separate from the main chamber and connected to the main chamber such that a compression action applied to an exterior of the inflation chamber when the inflation chamber is at least partially inflated causes an increase in pressure to facilitate inflation of the main chamber, the inflation chamber including:
- a first one-way valve positioned at an air inlet,
- a second one-way valve positioned at a connection point between the inflation chamber and the main chamber, and
- an air holding section;
- and
- a deflation chamber separate from the inflation chamber including:
- a third one-way valve positioned at an air outlet and the configured to release air from the main chamber, and
- a chamber section.
A seat cushion comprising:
- a main chamber that provides adjustable cushioning including:
- multiple air chambers, and
- a connecting channel;
- and
- an inflation chamber separate from the main chamber and connected to the main chamber such that a compression action applied to the inflation chamber when the inflation chamber is at least partially inflated causes an increase in pressure within the main chamber to facilitate inflation of the main chamber, the inflation chamber including:
- a first one-way valve positioned at an air inlet,
- a second one-way valve positioned at a connection point between the inflation chamber and the main chamber, and
- an air holding section.
