A pneumatic bladder arrangement includes a plurality of bladders arranged in an array of rows and columns. The array comprises a first array section and a second array section with the first and second array sections each comprising at least one column of bladders. The pneumatic bladder arrangement also includes at least one element for the supply or distribution of fluid to the plurality of bladders provided or formed between two flexible sheets of material by welding the respective two sheets of material to each other.

A seat cushion includes a plurality of inflatable cells, a pumping mechanism, and a manifold or valve system fluidly between the pumping mechanism and the inflatable cells. The manifold or the valve system, which may include a clutch and a motor, connect the pumping mechanism with the inflatable cells such that a plurality of zones are created. A valve assembly can include a plurality of valves and is adjustable among at least three valve configurations to vary fluid connections to the inflatable cells to produce rearwardly advancing waves. The pumping action produced by the inflation and deflation of the inflatable cells assists in pumping blood in a user's legs back toward the heart.

A method for adapting massage sequences to different types of seats, which have a number of inflatable cushions arranged at specified locations in the seat, is described. Here, a calculation model is parameterized for a specific seat type, and the duration of control commands for filling and ventilation of a cushion is adapted for each step such that a specified degree of filling is achieved, wherein the total temporal length of a step may vary in order either to achieve continuous operation of the compressor or in order to adhere to pauses of a defined minimum duration in the activation of the compressor.

A seat cushion assembly includes a base defining a leg support, a support portion recessed relative to the leg support, and a well recessed relative to the support portion, and an air pad assembly including a first air support member and a second air support member, the first air support member being positioned on the recessed support portion, and the second air support member being removably received by the well.

A cushion airbag pad, which comprises: a cushion body, comprising a pad body; a plurality of airbags; and a plurality of airways; and a one-way air admittance member mounted in the cushion body and internally provided with a one-way air admittance channel; wherein the one-way air admittance channel is provided with an air inlet port and at least one air outlet port, and at least two ends of the one-way air admittance member are fixed to the cushion body, and one end of the at least two ends, away from the air inlet port, of the one-way air admittance member is fixed to the pad body, such that warping of the one-way air admittance member is inhibited, thereby keeping the one-way air admittance member in a non-bending state.

An inflatable seat cushion device is provided. The device is designed to enhance ergonomic seating by replicating the dynamic benefits of an exercise ball while ensuring stability for prolonged office use. The device comprises a base that secures an inflatable cushion in place. A hinged lid with a locking mechanism encloses the cushion and features a dome-shaped inflatable member. A fabric cover encases the cushion, offering a breathable, stretchable surface with a non-slip exterior for added stability. The cushion's inflation level is adjustable via an accessible valve, allowing users to customize firmness and height. When inflated, the cushion has a dome shape that facilitates micro-movements, engaging core muscles and promoting improved posture. The device is used by positioning the base on a chair, securing the cushion assembly within the base, inflating the cushion through the valve, and allowing the user to experience active sitting benefits.

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.
