A lumbar support system for use in an ejection seat of an aircraft, comprising may comprise a pump; a plurality of bladders fluidly coupled to the pump; and a controller electrically coupled to the pump, the controller operable to: select a bladder in the plurality of bladders to fluidly isolate the bladder from a remainder of bladders in the plurality of bladders; and command the pump to inflate the bladder.

A system having a controller includes one or more thermal generation element assemblies, or a plurality of air bladder assemblies, or a plurality of electromagnetic coil assemblies, or a combination thereof, that are in communication with the controller and are configured for activation by the controller. The one or more thermal generation element assemblies, or the plurality of air bladder assemblies, or the plurality of electromagnetic coil assemblies, or a combination thereof are configured to provide a holistic mitigating effect on a vehicle occupant confined within the interior space of a vehicle for long periods of time.

A seat device includes a holding member that holds an air tube and is located below a seat cushion. The holding member includes a base wall that defines a holding surface for the air tube, a locking portion that locks air tubes routed along the holding surface on the base wall, and a side wall extending in a routing direction of each of the air tubes.

A condition correction unit includes a plan storage unit configured to store correction plans showing contents of correction of the body condition of a seated person, a presentation unit configured to read a correction plan based on a current value measured by a measurement unit from the plan storage unit and present the correction plan to the seated person, and a processing execution unit configured to execute processing to correct posture by controlling an operating unit. The plan storage unit stores the correction plan presented by the presentation unit in association with information identifying the seated person when the correction plan is presented. The processing execution unit reads the correction plan associated with the information identifying the seated person from the plan storage unit, and executes the processing to correct the posture according to correction contents shown by the correction plan.

An occupant support includes a seat and a seat cover. The seat is adapted to support an occupant resting thereon. The seat cover is coupled to the seat and arranged to lie between the occupant and the seat.

In embodiments, an aircraft passenger seat assembly includes a seatback assembly including one or more lateral seatback sections. In embodiments, at least one lateral seatback section includes a base seatback panel coupled to a seatback frame, a first set of segmented seatback panels coupled to the base seatback panel, and a second set of segmented seatback panels coupled to the first set of segmented seatback panels. In embodiments, the aircraft passenger seat assembly further includes a plurality of actuatable assemblies, wherein the plurality of actuatable assemblies include a first set of actuatable assemblies configured to selectively actuate the first set of segmented seatback panels relative to the base seatback panel, and a second set of actuatable assemblies configured to selectively actuate the second set of segmented seatback panels relative to the first set of segmented seatback panels.

A seat assembly includes a cushioned component having a lattice matrix, wherein the lattice matrix includes a first portion defined by a first pattern of interconnected links which defines a first set of cells, and a second portion defined by a second pattern of interconnected links which defines a second set of cells. The first portion of the lattice matrix includes a density profile that is different than a density profile of the second portion of the lattice matrix. An air bladder is disposed within a core portion of the lattice matrix and includes a non-porous outer casing surrounding an interior cavity. The outer casing of the air bladder and the lattice matrix are integrated components comprised of a common material to define a monolithic structure created using an additive manufacturing process.

A seat device includes a seat cushion where a sitting person is seated, and a seatback configured to support the upper body of the sitting person. The seatback includes a seatback frame, a seatback pad placed on a front face of the seatback frame, and a seatback cover covering a surface of the seatback pad. A plurality of stretch airbags is provided in a part of the seatback at a position corresponding to the lumbar part of the sitting person, and the stretch airbags are configured to inflate and press a surface of the seatback to a direction approaching the sitting person. The stretch airbags are placed to overlap each other in a thickness direction of the seatback such that the seatback pad is sandwiched between the stretch airbags.

A seat support element having an outer layer that includes an outer surface and an inner surface, a synthetic skin extending over the inner surface of the outer layer, and a first foam layer extending over the synthetic skin. A method of forming the seat support element includes the following steps: forming the outer layer by applying at least one layer of paint against a first forming surface of a forming tool, applying the synthetic skin against the inner surface of the outer layer, and applying the first foam layer against an inner surface of the synthetic skin.

A system having a controller includes one or more thermal generation element assemblies, or a plurality of air bladder assemblies, or a plurality of electromagnetic coil assemblies, or a combination thereof, that are in communication with the controller and are configured for activation by the controller. The one or more thermal generation element assemblies, or the plurality of air bladder assemblies, or the plurality of electromagnetic coil assemblies, or a combination thereof are configured to provide a holistic mitigating effect on a vehicle occupant confined within the interior space of a vehicle for long periods of time.
