Vehicle seat, in particular utility vehicle seat
First Claim
1. A vehicle seat, comprising:
- a) a scissor-type stand, which is able to vibrate and which can be adjusted in height, and comprising a pneumatic spring and at least one pair of cranks, which intersect at a scissor shaft; and
b) a control device for level control and for height adjustment of the scissor-type stand, the control device comprising a control element, a valve device, which can be controlled by the control element, to control the pneumatic spring, a switching element, which is movable relative to the control element or to the valve device, and a bearing for the switching element, wherein the control element and the valve device are kinematically assigned to different parts of the scissor-type stand, the parts being movable relative to one another;
wherein the control element is linked, by a connecting link, to a first crank of the at least one pair of cranks, the bearing is spaced apart from the scissor shaft and connected with a second crank of the at lest one pair of cranks, and the valve device is connected with the switching element, which is movable relative to the control element;
wherein the bearing rotatably supports the switching element about an axis, and the swithching element rotatably supports the control element about the axis.

Abstract
A vehicle seat has a scissor-type stand vibratable and adjustable in height, with a pneumatic spring and cranks, intersecting at a scissor shaft. A control device for level control and for height adjustment of the stand has a control element, a valve device controlled by the control element, for controlling the spring, a switching element movable relative to the control element or the valve device, and a bearing. The control element and valve device are kinematically assigned to different parts of the stand movable relative to one another. The control element is linked to a first crank. The bearing is spaced from the shaft and connected with a second crank. The valve device is connected with the switching element movable relative to the control element.
