Abstract
The invention relates to a vehicle vibration device of a vehicle seat or of a vehicle cab, comprising a lower part and an upper part which can be deflected relative to this lower part, in which device the upper part and the lower part are interconnected in a spring-loaded manner by means of at least one suspension apparatus and in which the suspension apparatus comprises a deformable fluid-spring part having a flexible pressure chamber element and a deformation apparatus having deformation elements, the deformable fluid element being deformed at least in part by the deformation elements when the upper part is deflected relative to the lower part, and wherein, according to the invention, an additional anti-abrasion element is arranged between the flexible pressure chamber element and the deformation elements.
