Abstract

Suspension system for vehicle seats, in particular for utility motor vehicle seats, comprising at least a first and a second part, the two parts being mounted oscillatorily movable and spring-loaded with respect to one another, wherein a closed hydropneumatic circuit is provided which comprises at least one control element, connected to at least one of the two parts, and at least one first hydropneumatic spring connected in series therewith, a hydraulic pressure of a hydraulic medium in the circuit being convertible into a force acting between the two parts by means of an action surface arranged in the control element, the pressure being dependent on a gas pressure in a gas volume of the first spring.
