A seat support mechanism that is adapted to constrain motion of a bottom of a seat relative to a floor as the seat bottom moves up and down relative to the floor, where the seat has a seat back, and where the seat is constructed and arranged to support an occupant thereof above the floor, wherein the seat bottom has a front edge, and wherein the seat bottom supports the occupant's thighs with the knees in front of the front edge of the seat bottom. The seat support mechanism is constructed and arranged such that as the seat bottom is moved up and down, the seat support mechanism causes the seat bottom to pivot about a virtual lateral horizontal pivot axis located farther from the front edge of the seat bottom than the occupant's knees. The seat support mechanism is further constructed and arranged such that the back of the seat remains at a relatively constant angle to the floor as the seat bottom moves up and down and pivots.

The invention relates to a device for damping an upper suspension part in at least one spatial direction with respect to a lower suspension part movable relative thereto, wherein a spring apparatus which acts between the upper suspension part and the lower suspension part is provided for damping, wherein an actuating element is provided by way of which a force can be introduced into the device bidirectionally in the operating direction of the spring apparatus, wherein the actuating element is actuable via a control apparatus, wherein the actuating element comprises a drive, preferably in the form of a rotary field magnet, and a coupling rod, drivable by the drive and in the form of a shaft, in such a way that a distance between the lower suspension part and upper suspension part can be varied as a result of the coupling rod rotating.

Equipment and processes generate a seating solution by obtaining occupant data, calculating body dimensions from the occupant data, and calculating a best-fit body arrangement for an occupant. Occupant data may be obtained in various ways using available computational devices and software or by manually measuring the relevant dimensions on the occupant. A user interface for inputting occupant metrics and/or occupant measurements may be provided in a mobile terminal included in the vehicle or separate from the vehicle, thus giving users increased flexibility while maximizing simplicity and usability for the user or other personnel obtaining the data. Once an occupant's best-fit body arrangement is determined, it may be altered by changing the predetermined criteria to achieve optimum comfort, safety, and therapeutic benefit as well as used for providing improved comfort on a continuous basis and/or in response to detected or predicted vehicle, road, or atmospheric conditions.

Suspension system for vehicle seats, in particular for utility motor vehicle seats, comprising at least a first and a second part, the two parts being mounted oscillatorily movable and spring-loaded with respect to one another, wherein a closed hydropneumatic circuit is provided which comprises at least one control element, connected to at least one of the two parts, and at least one first hydropneumatic spring connected in series therewith, a hydraulic pressure of a hydraulic medium in the circuit being convertible into a force acting between the two parts by means of an action surface arranged in the control element, the pressure being dependent on a gas pressure in a gas volume of the first spring.

The invention relates to a suspension device, in particular for a vehicle seat, comprising an upper suspension part and a lower suspension part, which can be connected to one another by a first swivelling connector and a second swivelling connector, wherein a first spring unit can be connected in a first end region on the one hand by means of an adjusting device to the first swivelling connector and can be connected in a second end region on the other hand to the lower suspension part, wherein by means of the adjusting device the position of the first spring unit can be adjusted in order to adjust the spring force and the spring rate of the suspension device.

A vehicle seat operation feedback and control system with a seat and an electronic display screen and a processor configured to receive a signal from the seat corresponding to an inoperable, almost inoperable, or undesired condition and provide feedback on the display screen of the inoperable, almost inoperable, or undesired condition.

A vehicle seat assembly includes a seat pan and four linkage arms individually pivotably coupled with the seat pan. The assembly further includes a mounting plate, each of the four linkage arms being pivotably coupled therewith. A gear rack is coupled with the seat pan and defines an articulation path therefor, and a pinion is operably engaged with the rack to drive articulation of the seat pan including pivoting of the four linkage arms and sliding of the mounting plate.

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 fine suspension device of the suspension apparatus may use a combination of passive and semi-active components. In some embodiments, the neutral height is adjustable.

The invention relates to a vehicle seat or a vehicle cab with a suspension system comprising an upper closing part and a lower closing part which is deflectable in relation to the upper closing part, which closing parts are connected to each other in a resilient manner by means of a suspension element, and with a damping system for damping vibrations acting on at least one of the two closing parts, wherein the damping system and a distance levelling system for adjusting a distance between the upper closing part and the lower closing part have a common fluid actuator element controlled by compression and tension stages.

Various embodiments of the present technology may comprise a method and apparatus for a space-saving suspension system. In various embodiments, the apparatus may comprise a fine suspension device, a coarse suspension device, and a mechanical assembly. In various embodiments, the fine suspension device is arranged at an angle greater than zero degrees from the z-axis. In various embodiments, the mechanical assembly is coupled to the fine suspension device and a payload, such that when a force is exerted on the mechanical assembly by the payload, an applied force is transmitted to the fine suspension device.
