Device for damping an upper suspension part in at least one spatial direction with respect to a lower suspension part movable relative thereto
First Claim
1. A device for damping a vehicle seat, comprising:
- an upper suspension part and a lower suspension part, the upper suspension part is configured to dampen oscillations in at least one spatial direction with respect to the lower suspension part and is movable relative thereto,a spring apparatus which acts between the upper suspension part and the lower suspension part being provided for damping the oscillations,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, in the form of a rotary field magnet, positioned in a space defined between a plurality of links of a scissor-type support apparatus, anda coupling rod, drivable by the drive and in the form of a shaft, extends through the drive and rotates about an axis of the rotary field magnet, the coupling rod is fixedly and non-rotatably connected to lower ends of the plurality of links of the scissor-type support apparatus, and the coupling rod is fixedly and rotatably connected to the lower suspension part,wherein the control apparatus is configured to actuate the drive, which rotates the coupling rod about the axis and moves the plurality of links so 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,wherein the actuating element levels temporary deviations in the distance between the lower and upper suspension parts and actively engages in isolating the oscillations.

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.
