1. An apparatus for springing a mass, comprising: a fluid spring and a frame, wherein the fluid spring is arranged between the mass and the frame in such a way that the mass is mounted on the frame in at least one of a sprung or damped manner;a fluid volume controller configured to modify the fluid
1. An apparatus for springing a mass, comprising: a fluid spring and a frame, wherein the fluid spring is arranged between the mass and the frame in such a way that the mass is mounted on the frame in at least one of a sprung or damped manner;a fluid volume controller configured to modify the fluid volume to the fluid spring, wherein the fluid volume controller comprises at least two fluid volume chambers configured to be fluidically connected to one another and which have at least one common, displaceable chamber wall; andan actuated piston defining the common, displaceable chamber wall, wherein the at least two fluid volume chambers of the fluid volume controller are separated by the actuated piston; anda shut-off valve interposed between the fluid spring and a first volume chamber of the fluid volume controller;a pressure equalizing valvewherein the apparatus is configured to adjust the common, displaceable chamber wall and to both fluidically connect the at least two fluid volume chambers to one another via the pressure equalizing valve and close the shut-off valve during adjustment of the common, displaceable chamber wall. 2. The apparatus according to claim 1, wherein the at least two fluid volume chambers of the fluid volume controller are adjustable with regard to their fluid volume. 3. The apparatus according to claim 1, wherein the fluid volume controller comprises a two-chamber cylinder with said actuated piston. 4. The apparatus according to claim 1, wherein the fluid volume controller comprises an actuator for adjusting a fluid volume of at least two of the fluid volume chambers. 5. The apparatus according to claim 1, wherein the fluid volume controller comprises an actuator for displacing the actuated piston of the fluid volume controller. 6. The apparatus according to claim 1, wherein the mass comprises a body component of a vehicle. 7. The apparatus according to claim 1, wherein the mass comprises a movable part of a seat. 8. The apparatus according to claim 1, wherein the fluid spring is coupled to a scissors control arm of a seat. 9. The apparatus according to claim 1, wherein the mass is a vehicle seat. 10. An apparatus for springing a mass, comprising: a fluid spring and a frame, wherein the fluid spring is arranged between the mass and the frame in such a way that the mass is mounted on the frame in at least one of a sprung or damped manner;an add-on-fluid volume means for providing an additional fluid volume for the fluid spring, the add-on-fluid volume means comprising at least two fluid volume chambers that can be fluidically connected to one another and which have at least one common, displaceable chamber wall,an actuated piston, wherein the common, displaceable chamber wall is defined by the actuated piston, and wherein the at least two fluid volume chambers of the add-on-fluid volume means are separated by the piston; anda shut-off valve interposed between the fluid spring and a first volume chamber of the at least two fluid chambers, the shut-off valve further operatively coupled to the fluid volume controller;a pressure equalizing valve;wherein the apparatus is configured to adjust the displaceable chamber wall and to both fluidically connect the at least two fluid volume chambers to one another via the pressure equalizing valve and close the shut-off valve during adjustment of the displaceable fluid wall. 11. The apparatus according to claim 10, wherein the at least two fluid volume chambers of the add-on-fluid volume means are adjustable with regard to their fluid volume. 12. The apparatus according to claim 10, wherein the add-on-fluid volume means comprises a two-chamber cylinder. 13. The apparatus according to claim 10, wherein the add-on-fluid volume means comprises an actuator for adjusting the fluid volumes of at least two of the fluid volume chambers. 14. The apparatus according to claim 10, wherein the add-on-fluid volume means comprises an actuator for displacing the common, displaceable chamber wall of the two fluid volume chambers of the add-on-fluid volume means. 15. The apparatus according to claim 10, wherein the mass comprises a body component of a vehicle. 16. The apparatus according to claim 10, wherein the mass comprises a movable part of a seat. 17. The apparatus according to claim 10, wherein the fluid spring is coupled to a scissors control arm of a seat. 18. A method for manipulating a fluid spring comprising: fluidically connecting the fluid spring to a fluid volume chamber of a plurality of fluid volume chambers, the plurality of volume chambers being separated by an actuated piston;manipulating the fluid spring by selectively connecting the plurality of fluid volume chambers to one another and adjusting the actuated piston;manipulating a shut-off valve interposed between the fluid spring and a first volume chamber of the plurality of fluid volume chambers;adjusting the actuated piston and, during actuation of the piston, both of a) fluidically connecting the plurality of volume chambers to one another and b) closing the shut-off valve; andleaving the shut-off valve open other than during adjustment of the piston. 19. The method according to claim 18, further comprising: determining at least one characteristic operating value on a suspension system associated with the fluid spring; andmodifying the fluid volume in at least two of the plurality of fluid volume chambers based on the determined at least one characteristic operating value.
