Embodiments described herein provide a cushion with active seating capacity, the cushion having a sitting portion and a rigid material to maintain the sitting portion.

An air bladder system is provided with a pair of lateral spaced apart air bladder assemblies, each provided with a primary region received in a seat bottom of a seat assembly. The primary region is expandable in a height direction to support a pelvis of an occupant. A secondary region extends from the primary region and is expandable for angular adjustment relative to the primary region to support a femur of the occupant. A plurality of sensors detects a seating position of an occupant. A controller is in electrical communication with the sensors and the air bladder assemblies. The controller is configured to receive data from the plurality of sensors. The data is compared to determine if the occupant is seated evenly. At least one of the air bladder assemblies is adjusted to balance an uneven left-to-right occupant seating position.

An inflatable bladder includes, but is not limited to, a bladder body having a wall, a longitudinal dimension, and a lateral dimension. The wall defines an interior volume enclosing a fluid. The wall further defines an opening in fluid communication with the interior volume. The bladder body is fluid tight when the opening is closed. The wall is configured to facilitate an expansion of the longitudinal dimension during an ingress of the fluid into the interior volume and a contraction of the longitudinal dimension during an egress of the fluid from the interior volume. The wall is further configured to maintain a constant lateral dimension during the ingress of the fluid into the interior volume and a constant lateral dimension during the egress of the fluid from the interior volume.

A method for operating an assisting system for the disabled is disclosed. The assisting system includes a cushion, which includes a plurality of cushion chambers. The pressure in the cushion is measured by a pressure sensor. If the measured pressure is found to be above a threshold, a deflation of the cushion follows. Contrarily if the pressure is lower than the threshold, inflation of the cushion follows.

Lumbar lordosis facilitator device composed of one or several fluid bags (1). Each bag (1) has one or several fluid entry points (2) connected to a pressurized fluid source (7) so that they allow the filling of the bag or bags (1) from a primary end to one or several fluid exit points (3) located in a way that allow the evacuation of the fluid to a secondary end on the opposite side of the primary end. The device also has a fluid inner pressure regulating system that can employ several sensor systems (8,9,10).

An anti-pinch system for an electric seat includes a plurality of infrared sensing modules, a seat cushion hose, a footrest hose, a pressure sensor, at least one linear actuator, a central processing unit, a power module and a control module. When the user operates the electric seat to act, the plurality of infrared sensing modules and the pressures sensor synchronously sense whether an obstacle is under the electric seat. If an obstacle exists under the electric seat, the central processing unit will control the at least one actuator to stop or to reversely act. When the user cannot perceive obstacles by themselves, the electric seat can be automatically prevented from pinching obstacles, thus avoiding damaging the obstacles or the electric seat.

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 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.

A pneumatic bladder arrangement comprises a plurality of bladders arranged in an array of rows and columns, wherein the array comprises a first array section and a second array section with the first and second array sections each comprising at least one row of bladders. The pneumatic bladder arrangement may be used in a support apparatus for a seat, in particular for a backrest of a seat.

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.
