A vehicle seat (), in particular a commercial vehicle seat, includes a scissor-type (scissors) framework () for adjusting the height. The scissors framework has intersecting rockers () and at least one frame (), and at least one bearing device () for movably guiding the rockers () in the frame (). A rotatable bearing roller () interacts with a first guide and a rotatable compensation roller () interacts with a second guide attached to a base region () of an insert (). A lateral region () of the insert () extends perpendicularly to the base region () and is fixed to the frame () and/or a head region () of the insert (), extending parallel to the base region (), is fixed to the frame (). The base region () is resiliently designed and presses against the compensation roller ().

Vehicle seat

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.

Vehicle seat, in particular utility vehicle seat

A vehicle seat has a scissor-type stand vibratable and adjustable in height, with a pneumatic spring and cranks intersecting at a scissor shaft, and a control device for level control and height adjustment of the stand. The control device has a driver, a switching element coupled with the driver, and a valve device controlled by the switching element, for controlling the pneumatic spring. The driver and the valve device are kinematically assigned to different parts of the stand, such parts being movable relative to one another. The switching element is spaced from the shaft and rotatably supported on the first crank. The valve device is connected with the first crank, and the driver is configured as a Bowden cable, the core of which is coupled with the switching element, and the jacket of which is fixedly connected with the second crank.
