Abstract

The invention concerns a spring system for use in vehicles for adjustment of the suspension characteristics, comprising at least one spring element to provide a spring force, an upper and a lower arrangement area to receive forces, a scissors-type frame arranged between the upper and the lower arrangement area for coupling the spring element with at least one force acting on one of the arrangement areas. According to the invention the spring element is coupled with a deflection means to influence the spring force and between the deflection means and a segment of the scissors-type frame an active connection can be created to transmit forces.
