Described herein are illustrative embodiments of a multi-pivot seat base assembly including a first pivot assembly having a fixed part mountable to a floor and a pivotable part, a proximate arm having a proximate end mounted to the pivotable part of the first pivot assembly and a distal end including a fixed part of a second pivot assembly, a distal arm having a proximate end provided with a pivotable part of the second pivot assembly; the proximate end of the distal arm being pivotally mounted to the fixed part of the second pivot assembly; the distal arm including a distal end provided with a seat receiving post; and a controllable damping mechanism provided between the fixed part and the pivotable part of the first pivot assembly.

A utility vehicle includes a frame, a first ground-engaging element coupled to a first portion of the frame, a second ground-engaging element coupled to a second portion of the frame, an operator platform supported by the frame, and a suspension system coupled between the operator platform and the frame to accommodate motion of the frame relative to the operator platform. The suspension system includes a first linkage assembly coupled to the operator platform and operable to accommodate motion of the second portion of the frame relative to the operator platform and a second linkage assembly having a first end coupled to the frame to secure the suspension system to the frame and a second end coupled to the first linkage assembly. The second linkage assembly being operable independent of the first linkage assembly to accommodate motion of the first portion of the frame relative to the operator platform.

A seat part which includes a cushion foam spanned by a seat cover is part of a seat system having an adjusting device by which flexibility of the seat part is variable. The adjusting device includes at least one guy device, disposed in a guy trench of the seat system, having a guiding element attached to an outer area of the seat cover and movable relative to the cushion foam between a first position relaxing the seat cover and a second position tensioning the seat cover or varying the flexibility of the seat part.

The invention relates to a vehicle seat with a horizontally movable seating surface for receiving a person, a retaining means which can be rigidly connected to a vehicle, and a horizontal spring system and a vertical spring system, wherein both the horizontal and vertical spring systems are configured as fluid systems, wherein the fluid systems are supplied by a central fluid supply and the fluid system of the horizontal spring system being separated from the fluid system of the vertical spring system by at least one valve.

The invention relates to an adjustable damping system for a vehicle seat for damping vibrations of a seat-part-side upper part relative to a body-side lower part in at least one spatial direction (X, Y, Z), at least one damping element, arranged between the seat-part-side upper part and the body-side lower part and adjustable by an adjustment device, being provided for the damping. The damping system is further distinguished in that at least one relative movement variable and a change in the relative movement variable of the seat-part-side upper part relative to the body-side lower part can be determined by a sensor device, and a first damping force of the damping element can be adjusted by the adjustment device as a function of the at least one relative movement variable and the frequency of the change in the relative movement variable.
