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 seat cushion comprising:
- a main chamber that is inflatable:
- an inflation chamber separate from the main chamber and connected to the main chamber, and defined between a first one-way valve and a second one-way valve;
- a deflation chamber including a third one-way valve configured to release air from the main chamber, and
- an attachment mechanism configured to couple to at least one seat cushion accessory, the attachment mechanism including:
- a cushion tab portion configured to couple to an accessory groove portion on the at least one seat cushion accessory.
An inflatable seat cushion comprising:
- a main chamber having multiple air chambers and a connecting channel to provide adjustable cushioning to a user;
- an inflation chamber separate from the main chamber and connected to the main chamber, and defined between a first one-way valve positioned at an air inlet and a second one-way valve positioned at a connection point between the inflation chamber and the main chamber;
- and
- an attachment mechanism configured to couple to at least one seat cushion accessory, the attachment mechanism including:
- a cushion tab portion that couples to an accessory groove portion on the at least one seat cushion accessory, and
- a cushion groove portion that couples to an accessory tab portion on the at least one seat cushion accessory.
A cushion comprising:
- a main chamber configured to provide cushioning to a user using stored air:
- an inflation chamber separate from the main chamber and connected to the main chamber such that a compression action applied to the inflation chamber 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
- an attachment mechanism configured to couple to at least one seat cushion accessory, the attachment mechanism including:
- a cushion groove portion configured to couple to a corresponding tab portion on the at least one seat cushion accessory.
