A kinetic seat assembly includes a primary seat cushion frame, a secondary seat cushion frame movable relative to the primary seat cushion frame, a primary seat back frame, a secondary seat back frame movable relative to the primary seat back frame, a pair of lateral dampers extending between the primary seat back frame and the secondary seat back frame, a pair of vertical dampers extending between the secondary seat back frame and the primary seat cushion frame, a pair of fluid reservoirs for providing a fluid into the pair of lateral dampers and the pair of vertical dampers, and an electronic control unit configured to control the rate at which the fluid is provided to and drawn out of each of the dampers to control a damping effect. In embodiments, an end of the lateral dampers is permitted to move freely relative to the secondary seat back frame.

An articulation assembly for a vehicle seat includes a planar engagement surface. An inflatable member is operably coupled to the planar engagement surface. The inflatable member includes a plurality of polyhedral bodies that are configured to be formed via additive manufacturing. Each of the polyhedral bodies has a foldable portion that defines crease lines. A plurality of elastomeric members are disposed on each crease line. A planar base includes a port fluidly coupled to the polyhedral bodies. A manifold is fluidly coupled to the port of the planar base and is configured to translate fluid through the port to the polyhedral bodies.

A kinetic seat assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat assembly includes a primary seat cushion frame, a primary seat back frame, a secondary seat cushion frame pivotally connected to the primary seat cushion frame, and a secondary seat back frame pivotally connected to the primary seat back frame. The kinetic seat assembly further includes a front pivot mechanism for damping movement between the primary seat cushion frame and the secondary seat cushion frame in a kinetic seat vertical direction, and an upper pivot mechanism for damping movement between the primary seat back frame and the secondary seat back frame in a kinetic seat longitudinal direction.

A seat adjusting structure includes a seat body. A damping force unit is installed at an upper end of the seat body, and a cab connecting plate is installed at a lower end of the seat body. An electronic controller and a seat weight sensor are installed between the damping force unit and the cab connecting plate. A rigidity unit and an operator presence indicator are installed at a lower part of the damping force unit, and a seat damper is installed above the cab connecting plate. The operator presence indicator detects whether an operator exists, while the seat weight sensor detects whether the weight of the operator is within a set range. The electronic controller receives detection signals from the operator presence indicator and the seat weight sensor and controls the damping force unit and the rigidity unit to adjust the rigidity and damping force of the seat damper.

A space-saving suspension apparatus comprising a coarse suspension device, a mechanical assembly, and a fine suspension device coupling a supported frame to a base frame at a neutral height such that forces and/or displacements of either the base frame or the supported frame result in oppositely directed forces and/or displacements of the other of the base frame and the supported frame. In some embodiments, the neutral height is adjustable.

A reclinable passenger seat includes a seat pan linear actuator having a rear end pivotally connected to the rear end of the seat pan frame, and a front end pivotally connected to the base by a third fixed pivot. A backrest linear actuator has an upper end pivotally connected to the upper backrest member, and a lower end pivotally connected to the base. A length of the backrest linear actuator is defined between the upper and lower ends. The backrest frame and seat pan frame are configured to move simultaneously between at least a reclined configuration and a berth configuration through pivoting motion about the first and second fixed pivots and about the first and second locations. The length of the backrest linear actuator is substantially the same in the reclined configuration and in the berth configuration.

The present invention is an elevated vehicle system. The preferred embodiment of the present invention has a steering wheel, an engine, a plurality of seats, a plurality of windows, and a plurality of wheels. The steering wheel rotates to turn the plurality of wheels. The engine has a transmission and power system.
