Claim:
1. A vehicle seat, comprising: a lower seat part; an upper seat part; a vertically adjustable seat connection unit which is arranged between the upper seat part and the lower seat part and which mechanically interconnects the lower seat part and the upper seat part, wherein the seat connection unit is formed by a scissor-action frame comprising at least two scissor arms; at least one oscillation limiting device arranged between the lower seat part and the upper seat part and rigidly connected to the upper seat part, wherein the oscillation limiting device comprises a mount, a reel-off cylinder rotatably interconnected to the mount on an axis of the reel-off cylinder, and a belt disposed about the reel-off cylinder, wherein the belt has a free end which is mechanically rigidly fastened on the lower seat part, wherein the belt has a presettable reel-off length, and wherein the oscillation limiting device is operable to limit a movement of the upper seat part to a maximum deflection height in a vertical direction, in a direction away from the lower seat part, after reel-off of the presettable reel-off length, without damping, an adjusting means operably interconnected to the mount and configured to adjust the presettable reel-off length of the belt, wherein the adjusting means comprises a bias spring and a manually operated catchable grip slidably supported on the mount for sliding movement along an adjustment axis, wherein the bias spring biases the grip along the adjustment axis of the adjusting means to a closed mode, which engages the grip with the reel-off cylinder and prevents rotation of the reel-off cylinder to set the presettable reel-off length of the belt, and wherein application of an external tension or pressure onto the grip moves the grip against the bias spring and along the adjustment axis of the adjusting means to an open mode, which allows free rotation of the reel-off cylinder and adjustment of the presettable reel-off length of the belt.
