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.

The invention relates to a vehicle seat, comprising a vertically adjustable seat connection arranged between and mechanically interconnecting an upper seat part and a lower seat part. At least one oscillation limiting device is provided to limit a vertical oscillation movement of the upper seat part in a direction away from the lower seat part, is arranged between the lower seat part and the upper seat part, and is rigidly connected to the upper seat part. The oscillation limiting device comprises at least one reel-off element with a presettable reel-off length that determines a maximum deflection height in the vertical direction. The oscillation limiting device limits movement of the upper seat part in the vertical direction, in the direction away from the lower seat part, after reel-off of the presettable reel-off length, without damping.

Suspension systems and grounds maintenance vehicles incorporating the same are disclosed. The suspension system may include biasing elements or springs that may be adjusted to vary the preload and thus change the spring and dampening characteristics of the suspension system. In some embodiments, the system may include an adjustment mechanism that permits simultaneous adjustment of two springs via a single action. In other embodiments, features adapted to assist an operator with mounting/dismounting the vehicle are disclosed.

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. The power system is a battery that provides power to various components within the present invention. The plurality of seats has a seatbelt, a hydraulic lift, and a plurality of buttons. The seatbelt is a flexible, nonelastic material that holds a passenger in their seat. The hydraulic lift is a mechanical system that lifts and lowers the seat. The plurality of buttons is used to control the height positioning of the seat. Additionally, a sensor is used to control the raising and lowering of the seats.

A driver's seat for a rail vehicle includes a seat, a frame, a support, a fastening unit and a compressed air line, ensuring compressed-air-assisted functionalities of the driver's seat. The frame supporting the seat is mounted rotatably and connected to a first end of the support permitting the seat to rotate about an axis of the support. A second end of the support is connected to the fastening unit, fastening the seat in a vehicle control console. The air line ensures compressed-air-assisted seat functionalities and has a first region with partial coils running around the support at a predefined distance. The partial coils are formed and fastened such that rotational movement of the seat effects a change in distance of the partial coils relative to the support. The partial coils of the air line form a spiral, wound around the support at a predefined distance.

A suspension component (730), including: an elastomeric component top member (832); an elastomeric component bottom member (830); and a plurality of elastomeric zig-zag columnar elements (800). The elastomeric zig-zag columnar elements connect the elastomeric component top member to the elastomeric component bottom member and are separated from each other by a gap (806).

Vehicular seat suspension systems that do not include scissor mechanisms or pivot joints to improve lateral stability and substantially eliminate deflection during operation, testing and/or crashes. In particular, the seat suspension systems include an inner element that is able to slide within a static outer element, allowing the system to bear high loads while ensuring lateral stability and substantially eliminating deflection experienced by convention seat suspension systems.

A suspension device including a lower member, an upper member, a raising and lowering mechanism, a spring, a variable characteristic damper having an adjustable damping force, a first sensor that detects a vertical velocity of the upper member, a second sensor that detects a vertical velocity of the lower member, a memory, and a processor that is coupled to the memory and that is configured to control the damping force of the variable characteristic damper. The processor is configured so as to selectively execute a normal control mode and a bottoming out prevention control mode. In the bottoming out prevention control mode, when the first sensor or the second sensor has detected that the upward or downward direction velocity has exceeded the reference velocity, the damping force of the variable characteristic damper is adjusted to a maximum damping force.

The invention relates to a vehicle seat, in particular for commercial vehicles, with an upper part and a lower part and with at least one air spring which exerts a resilient effect on a height-distance-movement which changes between the upper and lower parts, and with at least one damper element which damps the changing height-distance movement, wherein the air spring is connected at an air spring outlet to an adjustment device which adjusts a degree of damper hardness, which damps the changing height-distance-movement, wherein the air spring is connected at an air spring outlet to an adjustment device for adjusting a degree of damper hardness of the damper element, wherein the degree of damper hardness can be adjusted and changed by means of an air pressure of the air spring.
