The invention concerns a vehicle damping device for a vehicle seat (1)/vehicle cabin with a fixed lower part (5) and an upper part (4) vibrating in relation to the lower part (5) and at least one damper (9) arranged in between, where in a damping force-speed diagram, with rising speed (11) of the vibrating upper part (4) in relation to the fixed lower part (5), a damping force (10) of the damper (9) develops such that the damping force (10) in a first speed range (15) has a substantially linear first course (12) with a first gradient and in the second speed range (16, 18) a second course (14, 19) with a second gradient steeper than the first gradient.

1. A vehicle damping device for a vehicle seat (1) comprising a fixed lower part (5), an upper part (4) of the vehicle seat (1) vibrating in relation to the lower part (5), two or more scissor arms (6, 7) attaching the fixed lower part (5) to the upper part (4), and at least one damper (9) wherein o
1. A vehicle damping device for a vehicle seat (1) comprising a fixed lower part (5), an upper part (4) of the vehicle seat (1) vibrating in relation to the lower part (5), two or more scissor arms (6, 7) attaching the fixed lower part (5) to the upper part (4), and at least one damper (9) wherein one end of the damper (9) is mounted on one of said arms and a second end of the damper (9) is mounted on the fixed lower part (5), said damping device characterised in that in a damping force-speed diagram, with rising speed (11) of the vibrating upper part (4) in relation to the fixed lower part (5), a damping force (10) of the damper (9) develops such that the damping force (10) in a first speed range (15) has a linear first course (12) with a first gradient and in a second speed range (16, 18) a second course (14, 19) with a second gradient steeper than the first gradient, wherein the second gradient is always steeper than the first gradient independent of the position of a transition (17) of the damping force (10) from the first to the second course (12, 14, 19). 2. The vehicle damping device according to claim 1, wherein at a specific speed a transition (17) of the damping force (10) from the first (12) to the second (14, 19) course as a curve is step-like. 3. The vehicle damping device according to claim 1, wherein the first speed range (15) comprises speeds from 0 m/s to 0.1 m/s and the second speed range (16, 18) comprises speeds ≧0.1 m/s. 4. The vehicle damping device according to claim 1, wherein a rise of the damping force (10) is travel-dependent. 5. The vehicle damping device according to claim 4, wherein the rise in the damping force (10) in the tension direction and in the compression direction of the damper (9) is the same. 6. The vehicle damping device according to claim 4, wherein the rise in the damping force (10) in the tension direction and the compression direction of the damper (9) is different. 7. The vehicle damping device according to claim 4, wherein the rise in the damping force (10) in the first (15) and the second (16, 19) speed ranges can be set independently of each other. 8. The vehicle damping device according to claim 2, wherein the specific speed can be adjusted. 9. The vehicle damping device according to claim 2, wherein the damper (9) is switchable on the transition (17) from a first to a second working range, the first and the second working ranges allocated to the first (15) and the second (16, 19) speed ranges. 10. The vehicle damping device according to claim 1, wherein the two or more scissor arms (6, 7) are connected together at a pivot (8) so that the damper (9) is pivotally mounted on one of said arms and the fixed lower part (5).
