Parking brake device and vehicle brake system provided with such a parking brake device

摘要

The invention relates to a parking brake device comprising a spring element and an actuating element that acts upon the spring element, wherein by applying an actuating force to the actuating element the parking brake device is transferrable between a brake-inactive release position and a brake-active parking position. In the invention, it is provided that the spring element is biased in the release position and that the spring element upon transfer from the release position to the parking position yields only upon attainment of an actuating-force threshold value that is determined by the bias.
