Abstract

An apparatus for actuating a brake of vehicles, in particular a parking brake, has an electric motor and a coupling element which is movement-coupled with the motor drive shaft of the latter, is linearly movable, can be connected to a brake tensioning mechanism and is transferred by the energized electric motor out of a braking position into a release position. A blocking device provides the block on movement of the coupling element, at least in the release position. A spring energy store is movement-coupled with the coupling element such that, in the release position of the coupling element, the store assumes a position to store spring energy and, when the block on movement is overridden, the coupling element is transferred into the braking position by the released spring energy. The blocking device is mechanically held in its blocking position, effecting the block on movement, and can be actuated electrically and optionally mechanically for overriding the block on movement in the release position of the coupling element.
