An adjustable suspended seat apparatus having a tuned frequency-tailored damping through stratified seat structure is described. The damping seat structure includes: a first material of a plurality of materials having a first characteristic to provide a first damping effect in a first layer. A second material of the plurality of materials based on a second characteristic to provide a second damping effect in a second layer, the first material or the second material having an adjustable damping characteristic. The suspended seat apparatus includes a seat base configured to have the seat coupled thereto; a suspension system coupled to the seat base, the suspension system comprising: an adjustment feature configured to adjust operation of the suspension system; and a chassis mount coupled to the suspension system, the chassis mount configured to be coupled to a vehicle.

The invention relates to a vehicle seat comprising a backrest portion and a seating surface portion, each of which is arranged to be connected with a seat base portion, wherein the backrest portion is resiliently arranged and supported to be able to swivel with respect to the seat base portion, and wherein the seating surface portion is arranged to be able to move in at least a longitudinal direction of the seat frontwards and rearwards with respect to the seat base portion, wherein the backrest portion and the seating surface portion are operatively connected together via a first lever arrangement in such a way that the seating surface portion is able to move rearwards in the longitudinal direction of the seat when the backrest portion makes a suspending movement with respect to the seat base portion in a direction away from the seating surface portion.

An operator seat system is provided that includes an operator seat and an armrest control center with an I/O (input/output) system that is connected to and moves with the operator seat. An armrest control center mount system may include a seat mount and an armrest control center mount that are attached to each other with an adjustment system that allows adjustment of the armrest control center with respect to the operator seat.

A vehicle is provided with a vehicle frame or sub-frame structure and at least one of a body structure and engine structure or a plurality of suspension components mounted to the vehicle frame or sub-frame structure and a plurality of fluid-controlled spring/dampers supporting the least one of a body structure and engine structure or a plurality of suspension components to the vehicle frame of sub-frame structure, the plurality of fluid-controlled spring/dampers being connected to a single central pump.

An energy-absorbing assembly includes an outer assembly with an outer hollow cylindrical member, and an inner assembly with an inner hollow cylindrical member having an end disposed in the outer member. The inner and outer assemblies are axially movably engaged with each other and define first and second cavities separated by a membrane: a first cavity inside the outer hollow cylindrical member and a second cavity inside the inner hollow cylindrical member. An adjustable-size orifice is disposed between the first and second cavities, and is configured to reduce diameter in response to a stroke motion of the energy-absorbing assembly.

An occupant support includes a seat coupled to a seat base. The seat includes a seat bottom and a seat back. The seat back is coupled to the seat bottom to extend upwardly away from the seat bottom. Motion-sickness mitigation means facilitates relative movement between a support surface of the seat and the seat base.

An occupant support structure and a method of customizing an occupant support structure. The occupant support structure may comprise a base and a reconfigurable cushion carried by the base. The reconfigurable cushion may include an occupant support surface and a bladder. The bladder may include an outer wall that defines an inner cavity underlying the occupant support surface and two or more overlapping material layers disposed within the cavity. The overlapping material layers may be adapted to selectively transition from a compliant state to a rigid state and vice versa by selective control of a pressure condition across the outer wall of the bladder to reconfigure or conform the occupant support surface of the cushion to a contour of a portion of an occupant supported by the cushion.

A vehicle seat assembly includes a housing seat attachment portion with hooks in receipt of suspension wires. A housing bracket extends from a housing sidewall to provide a housing cavity and a housing opening. The housing bracket is spaced above the vehicle floor by at least fifty millimeters to provide clearance between the housing bracket and the vehicle floor. A pump is received within the housing cavity adjacent to the seat attachment portion. A cover is fastened to the housing seat attachment portion and the housing bracket to at least partially enclose the housing opening and to retain the pump within the housing. A light source is received within the housing cavity and is adjacent to the seat attachment portion to minimize a height of the housing. The light source is oriented away from the seat attachment portion to illuminate a region beneath the seat bottom frame.
