A vehicle seat having a residual spring travel controller and an air spring, the residual spring travel controller and the air spring each having a first end that is connected to a first connecting link of the vehicle seat and each having a second end that is connected to a second connecting link of the vehicle seat, and the residual spring travel controller comprising a piston element that is connected to the first end of the residual spring travel controller and a rod element that is connected to the second end of the residual spring travel controller, it being possible to bring the piston element into contact with a valve element or a switch element by means of a rotary and/or sliding movement with respect to the rod element to adjust an amount of air of the air spring.

A magnetic seat adjustment system includes a frame structure, a movable adjustment mechanism, and a control system. The frame structure includes a first magnetic portion fixedly coupled to the frame structure and including first magnetic members that independently generate a magnetic field. The movable adjustment mechanism includes a movable base and a second magnetic portion. The second magnetic portion is fixedly coupled to the movable base and includes second magnetic members that independently generate a magnetic field. The control system controls a change in the magnetic field of the second magnetic members and/or the first magnetic members. When the magnetic field of the second magnetic members interacts with the magnetic field of the first magnetic members, the seat is in a magnetic levitation state, so that movement of the movable base drives movement of the seat.

A sealed boat seat suspension including a plurality of sealed rails. The sealed boat seat suspension also includes a boat seat attachment component which is coupled to the plurality of sealed rails. The sealed boat seat suspension also includes a boat seat attachment component which is movable with respect to at least a portion of the plurality of sealed rails. The sealed boat seat suspension also includes a suspension component which is coupled to the boat seat attachment component such that the suspension component provides at least some control of movement of the boat seat attachment component with respect to at least a portion of the plurality of sealed rails.

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 working machine according to an embodiment of the present invention includes an operator seat, an operation base arranged in front of the operator seat, an operation member arranged on the operation base and configured to be gripped and moved, and an armrest member extending from the operation base toward a side of the operator seat.

An operating unit for specifying a desired value for a height adjustment apparatus of a vehicle seat, in particular utility vehicle seat, where the operating unit may have an operating element for actuating the height adjustment apparatus. The operating element may be continuously adjustable. Further, a vehicle seat, in particular utility vehicle seat, with an operating unit for specifying a desired value for a height adjustment apparatus of the vehicle seat is provided.

A seat for a vehicle includes a seat cushion and an adjustment and suspension device having a base fixed to the frame and a supporting plate fixed to the seat cushion movable in translation relative to the base in a direction of elevation. The seat also has a restraint system that includes: at least one restraint member fixed to the frame, the restraint member defining at least one through opening extending along a main direction of elongation substantially parallel to the direction of elevation; and at least one restraint element fixed to the supporting plate, the through opening of the restraint member receiving the restraint element free in translation along the main direction of elongation.

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 invention relates to an apparatus for adjusting a seat position for a vehicle seat, which comprises at least one support element for a seat part and can be connected to a seat substructure, wherein the apparatus comprises at least one first limb and at least one second limb, wherein the limbs can be rotatably arranged on the seat substructure and the at least one support element, wherein a first angle α between the first limb and the support element can be adjusted by an angle adjustment device, wherein the at least one first limb and the at least one second limb each have a lever portion, and these are mechanically coupled, and wherein a change in the angle α causes a displacement of the at least one support element along a height axis Z, and a change in an angle of inclination θ of the support element.

A vehicle seat having a lower part and an upper part displaceable relative to the lower part in a longitudinal direction, and a spring element for cushioning longitudinal horizontal movements of the upper part relative to the lower part. A scissors frame connects the lower part and the upper part so that they can move relative to one another. The spring element comprises a first holding arm connected to the upper part, and a second holding arm connected to the scissors frame. The first holding arm and the second holding arm are connected to one another by a first connecting element such that the first holding arm is displaced towards the second holding arm during a displacement of the upper part relative to the lower part. A resiliently deformable spring element part is deformed during a displacement of the first holding arm relative to the second holding arm.
