Abstract

A connecting element connects a brake pedal to a brake force amplifier of a vehicle brake system. A helical compression spring as a first spring element and a rubbery-elastic reaction disk as a second spring element are disposed between a pedal rod and a piston rod of the connecting element, the spring elements being installed in series due to the arrangement thereof. Due to the higher spring rate of the reaction disk preferably increasing with load, the connecting element has a progressive spring characteristic line. As soon as the pedal rod contacts the reaction disk the helical compression spring and the reaction disk act in parallel and serially such that the progression of the total spring characteristic line further increases.
