The invention relates to a suspension system (1), preferably a driver seat (1), comprising a first suspension part (10), preferably a frame (10) of the driver seat (1); a second suspension part (11), preferably a seat surface (11) of the driver seat (1), wherein the two suspension parts (10, 11) are movable relative to each other in at least one first spatial direction (Z), preferably in the vertical direction (Z); a kinematic system (12), preferably a scissor kinematic system (12) which is designed to connect the two suspension parts (10, 11) in a movable manner relative to each other at least in the first spatial direction (Z); a suspension device (13) which is designed to support the static load of the second suspension part (11); and an actuator (2) which is designed to introduce a force bidirectionally between the two suspension parts (10, 11) and thereby actively damp the relative movement between the two suspension parts (10, 11). The suspension system (1) is characterized in that the actuator (2) has a bearing (28), preferably a ball bearing (28), which is arranged within the power flow between the two suspension parts (10, 11) such that an axial load can be kept away from the driven axle of the actuator (2) at least partly, preferably completely.

There is described a vehicle seat suspension mechanism, comprising a vehicle mount, a seat support linked to the vehicle mount by a suspension arrangement which allows the seat support to fall with respect to the vehicle mount under load and a shock strut arranged to resist the seat support falling with respect to the vehicle mount during a compression stroke. A control link is arranged to be driven about a control link pivot by the fall of the seat support. The control link is pivotally coupled to a first end of the shock strut to guide the first end with respect to a second end of the shock strut in a manner which causes a motion ratio of the suspension mechanism to increase during progression of the compression stroke. The ride will feel softer for smaller impacts and better damped later for larger impacts. The mechanism is arranged underneath a seat of a vehicle to provide additional comfort for the rider.

This invention is a seat with an adjustable back and/or an adjustable base. The adjustable back and/or base can be adjusted in response to rough terrain or water encountered by a vehicle in which the seat is located.

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.

An air system for a seat includes an air pump, a first air operated task unit, and a second air operated task unit. The air pump is adapted to output a system air volume at a constant flow rate. The first air operated task unit is adapted to receive at least a portion of the system air volume and operate at a first pressure. The second air operated task unit is adapted to receive at least a portion of the system air volume and operate at a second pressure different than the first pressure.
