Abstract

The invention relates to a device for damping an upper suspension part in at least one spatial direction with respect to a lower suspension part movable relative thereto, wherein a spring apparatus which acts between the upper suspension part and the lower suspension part is provided for damping, wherein an actuating element is provided by way of which a force can be introduced into the device bidirectionally in the operating direction of the spring apparatus, wherein the actuating element is actuable via a control apparatus, wherein the actuating element comprises a drive, preferably in the form of a rotary field magnet, and a coupling rod, drivable by the drive and in the form of a shaft, in such a way that a distance between the lower suspension part and upper suspension part can be varied as a result of the coupling rod rotating.

Claims

1. A device for damping an upper suspension part in at least one spatial direction with respect to a lower suspension part movable relative thereto, comprising:

a spring apparatus which acts between the upper suspension part and the lower suspension part being provided for damping, wherein an actuating element is provided by way of which a force can be introduced into the device bidirectionally in the operating direction of the spring apparatus, the actuating element being actuable via a control apparatus, the actuating element comprising a drive, preferably in the form of a rotary field magnet, and a coupling rod, drivable by the drive and in the form of a shaft, in such a way that a distance between the lower suspension part and upper suspension part can be varied as a result of the rotation of the coupling rod.

2. The device according to claim 1, wherein the spring apparatus comprises a spring, which is arranged between the upper suspension part and the lower suspension part, and a scissor-type support apparatus, which connects the upper suspension part to the lower suspension part such that they are movable relative to one another.

3. The device according to claim 2, wherein the scissor-type support apparatus comprises a first scissors, consisting of a first inner link and a first outer link, and a second scissors, consisting of a second inner link and a second outer link, which are preferably interconnected via at least one transverse connection.

4. The device according to claim 3, wherein the drive is fixedly arranged on the upper suspension part or lower suspension part, respectively and the coupling rod in the form of a shaft is in the form of a fixed bearing transverse connection between the first inner link and the second inner link or between the first outer link and the second outer link, and is mounted rotatably in a fixed bearing.

5. The device according to claim 1, wherein at least one movement sensor is provided, by means of which the movements of the upper suspension part with respect to the lower suspension part in the at least one spatial direction can be detected, which can preferably be passed on to the control apparatus.

6. The device according to claim 1, an acceleration sensor is provided, by means of which accelerations between the upper suspension part and the lower suspension part can be detected, and can preferably be passed on to the control apparatus.

7. The device according to claim 1, a shock absorber is provided for damping oscillations of the spring apparatus.

8. A seat, in particular a vehicle seat, comprising a device according to claim 1.

9. A vehicle comprising at least one seat according to claim 8.

10. A vehicle comprising at least one device according to claim.

11. A device, comprising:

an upper suspension part;

a lower suspension part, wherein the lower suspension part is movable relative to the upper suspension part;

a spring apparatus, wherein the spring apparatus asked between the upper suspension part in the lower suspension part;

an actuating element, wherein a force can be introduced into the device bidirectionally in an operating direction of the spring apparatus, wherein the actuating element includes;

a drive;

a coupling rod, wherein the coupling rod is drivable by the drive, and wherein a distance between the lower suspension part in the upper suspension part can be varied as a result of a rotation of the coupling rod;

a control apparatus, wherein the actuating element is actuated via the control apparatus.

12. The device of claim 11, wherein the drive is a rotary field magnet.

13. The device of claim 11, wherein the coupling rod is a shaft.
