Abstract: A pneumatically adjustable bladder system (90) for use in a cushioned seat bottom (24) has one or two rear foam filled bladders (62, 64) for location under the ischial tuberosities of a seated occupant of the seat bottom, and one or more expansion chambers (14, 16) or front foam filled bladders (66, 68) for location under the thighs of the seated occupant. There are air passageways (70, 72, 74, 92) interconnecting the bladders with each other or with an expansion chamber. The system is air tight and the bladders are compressible under the weight of the seated occupant and are expandable when the weight is removed. The compression of a bladder causes air therewith in to be displaced through the air passageways to the expansion chambers or to the other bladders, which then expand. The compression of a bladder under the ischial tuberosities of the seated occupant and the expansion of the expansion chambers or of the other bladders under the thighs of the seated occupant cause the seated occupant to experience a correct level of immersion into the cushioned seat bottom which is desired for effective postural support and prevention of lower back pain.

Abstract: An inflatable cushion for body support is described. The inflatable cushion can be adjusted to manually/automatically set the proper pressure distribution, remove pressure from sensitive regions, alternate pressure, facilitate moisture removal, automatically detect leakage and avoid bottom down, communicate leakage and other problems with the user/caregiver, detect wrong positioning and facilitate position correction. The inflatable cushion can be used either as a chair cushion such as for example as a cushion for wheelchair or as a bed mattress.

Abstract: A seat cushion according to the present invention is configured as a fluid or gas containing bag. When weight of buttocks are transferred back and forth in left, right, front, rear directions, the fluid or gas contained therein will be transferred back and forth. The level of the fluid or gas contained in the seat cushion is defined by the manufacturer which is 5-40 millimeters. The fluid or gas is detained inside in use. The seat cushion can be laid on cushion of different seats and on the floor.

Abstract: 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.

Abstract: A waist support chair includes a framework, a back support member, and a hips support member. The framework includes a back support frame and a chair bottom pivotally coupled to each other. The back support member is arranged on the back support frame and adjacent to the chair bottom. The back support member includes two upper support elements horizontally disposed and left-right symmetric to each other and two lower support elements horizontally disposed and left-right symmetric to each other. Two lower support elements are disposed between two upper support elements and the chair bottom. The hips support member is arranged on the chair bottom and includes a plurality of hollow elastic columns. When pressure is applied to the hollow elastic columns, the hollow elastic columns are compressed to release air.

Abstract: 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.

Abstract: A seat assembly includes a cushioned component having a lattice matrix. An air bladder assembly is covered by the lattice matrix. The air bladder assembly includes a plurality of air bladders supported on a platform assembly. Each air bladder includes a body portion operable between deflated and inflated conditions. Each air bladder includes a connection stem. A support plate includes a plurality of access apertures disposed therethrough. The air bladder assembly is operably coupled to the support plate. Each air bladder is aligned with at least one access aperture of the plurality of access apertures. A carrier assembly includes a plurality of mounting apertures disposed through an outer surface thereof. The carrier assembly receives the connection stem of each air bladder through at least one mounting aperture of the plurality of mounting apertures of the carrier assembly.

Abstract: A hardness adjustment unit includes an elastic frame, a barrier, and a field generator. An enclosed space is provided inside the elastic frame and filled with a fluid filling. The barrier is arranged in the enclosed space and divides the enclosed space into an upper space and a lower space. The upper space communicates with the lower space. The field generator is arranged outside the elastic frame and used to apply a field to the fluid filling to adjust a viscosity of the fluid filling, thereby adjusting a flow damping of the fluid filling in the upper space and the lower space to control a deformation of the elastic frame.
