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.

A seat assembly is provided having a seat bottom and a seat back mounted adjacent the seat bottom. A cushion is disposed on at least one of the seat bottom and seat back and defines a seating surface. The seating surface has a plurality of regions. A controller is in communication with the cushion and is programmed to independently vary a stiffness of each of the regions along the seating surface.

The invention relates to a shock absorber with a housing, and an inner pipe arranged in the housing, a piston rod, a piston, and which piston divides the interior of the inner pipe into a lower chamber and an upper chamber, a first valve arrangement which is arranged on the piston, a second valve arrangement which is arranged at the upper end of the inner pipe, and a third valve arrangement which is arranged at the lower end of the inner pipe. The shock absorber is distinguished by the fact that at least one proportional flow-control valve is arranged between a first connecting element of the lower chamber of the inner pipe and a second connection element at the upper chamber of the inner pipe.

A lower guide frame for a vertical suspension system of a vehicle seat having a left-hand slide and, parallel thereto, a right-hand slide which are connected to each other via a lower crosspiece. Attached to an upper side of at least one slide is a reinforcing profile which has a horizontal portion, via which it is connected to the upper side of one slide, and adjoining the horizontal portion is an oblique portion that is oriented obliquely downwards and outward. Adjoining the oblique portion is a vertical portion that, in the assembled state, extends to just above a vehicle floor.

A riding lawn care vehicle (10) may include a frame (60, 130) to which wheels (31, 32) of the riding lawn care vehicle (10) may be attachable, a seat (20, 110, 310) which an operator of the riding lawn care vehicle (10) may utilize when operating the riding lawn care vehicle (10), a seat mounting structure (120, 320) to which the seat (20, 110, 310) may be mounted, an isolation assembly (140, 340) which may provide vibration isolation between the frame (60, 130) and the seat mounting structure (120, 320), and a hinge assembly (150, 350) which may enable the seat (20, 110, 310) to pivot via the seat mounting structure (120, 320). The isolation assembly (140, 340) may include a motion ratio adjustment assembly (160, 360) which may define a motion ratio of the isolation assembly (140, 340) independent of an amount of pre-loaded compression. The isolation assembly (140, 340) may be operably coupled to the seat mounting structure (120, 320) via the hinge assembly (150, 350) such that displacement of the seat (20, 110, 310) may be transferred to the isolation assembly (140, 340) via the hinge assembly (150, 350).

A seat suspension including a base frame having a back portion and a bottom portion fixedly securable to a support surface. A carriage assembly is movably connected to the base frame. The carriage assembly includes a transverse member slidably connected to the base frame and a vertical guide member extending upwardly from the transverse guide member and movably connected to the base frame. The carriage assembly includes a suspension support having a first end pivotally secured to the transverse member. A shock compensating mechanism including an adjustment member is slidably disposed on a pivot surface secured to the transverse guide member. Movement of the adjustment member changes shock compensation properties of the shock compensating mechanism. A height adjustment mechanism disposed on the frame includes an actuator wherein operation of the actuator selectively moves the seat frame, the carriage assembly, and the shock compensating mechanism relative to the base frame.

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.

The invention relates to a control valve (16) for an air spring, comprising a housing (41), an exhaust duct that has an exhaust tappet (26) for opening of closing the exhaust duct, which exhaust tappet interacts with a first control means (19), a ventilation duct that has a ventilation tappet (27) for opening or closing the ventilation duct, which ventilation tappet interacts with a second control means (20), and a supplemental duct having a supplemental tappet (28) for opening or closing the supplemental duct, which supplemental tappet interacts with a third control means (21), wherein a first air connection A connects to the exhaust duct and a second air connection P connects to the exhaust duct together with the supplemental duct, wherein a first control means (19) and a second control means (20) are arranged to one another in such a manner that said control means cannot be actuated at the same time by an control element (18), and wherein the second control means (20) and the third control means (21) are arranged to one another in such a manner that the supplemental duct can only be opened when the ventilation duct is opened. The invention further relates to a motor vehicle seat comprising a mechanical swing system and an air spring, which motor vehicle seat has such a control valve.

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.
