Abstract

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.

Claims

1. A vehicle seat with a horizontally movable seating surface for receiving a person, comprising:

a retaining means which can be rigidly connected to a vehicle, and a horizontal spring system and a vertical spring system, both the horizontal and vertical spring systems being configured as fluid systems, wherein the fluid systems are supplied by a central fluid supply and the fluid system of the horizontal spring system is separated from the fluid system of the vertical spring system by at least one valve.

2. The vehicle seat according to claim 1, wherein the fluid systems of the spring systems are configured as pneumatic systems.

3. The vehicle seat according to claim 1, wherein a respective pressure measuring means is provided for the vertical and the horizontal spring systems.

4. The vehicle seat according to claim 3, wherein the pressures in the fluid systems of the vertical and horizontal spring systems can be adapted to one another using the pressure values established by the pressure measuring means.

5. The vehicle seat according to claim 3, wherein the pressure measuring means are configured as position sensors for detecting the vertical and horizontal position of the seating surface, a comparison and conversion means being provided, by means of which the position values from the position sensors can be converted into pressure values.

6. The vehicle seat according to claim 1, wherein a choke is provided for reducing the pressure in the fluid system of the vertical spring system.

7. The vehicle seat according to claim 1, wherein further valves are provided, by means of which pressure can be reduced in the fluid system of the horizontal spring system via the choke, which pressure reduction is uncoupled from the pressure reduction in the fluid system of the vertical spring system.

8. The vehicle seat according to claim 1, wherein the valves are configured as non-return valves.

9. The method for controlling fluid systems of a horizontal and a vertical spring system of a vehicle seat according to claim 1, wherein the fluid which is required is removed from a common central fluid supply, it being possible for the fluid systems of the horizontal and vertical spring systems to be uncoupled from one another by at least one non-return valve.

10. The method according to claim 8, wherein the fluid pressure in fluid systems of a horizontal and a vertical spring system can be regulated by controlling inlet and outlet valves such that the seating surface can be moved into a predetermined position, particularly into a pre-programmed position.
