Abstract
A parking brake actuating device includes a rotary lever arrangement in operative connection with a compensation device providing an idle path and a restoring element for controlling the rotary lever arrangement. The rotary lever arrangement controls the engagement of a blocking member with a counter-blocking member of the parking brake arrangement. The rotary lever arrangement has a rotary lever input part and a rotary lever output part and the idle path of the compensation device can be constructed so as to be in an operative connection between the rotary lever input part and the rotary lever output part.

A parking brake actuating device for a parking brake arrangement in a motor vehicle, said parking brake arrangement comprising a blocking member and a counter-blocking member, said actuating device comprising:
- a rotary lever arrangement which controls engagement of the blocking member with the counter-blocking member, said rotary lever arrangement comprising a rotary lever input part and a rotary lever output part which are rotatable relative to each other along an idle path when said blocking member is not engaged by said counter-blocking member,
- an actuator in operative connection with said rotary input part, said actuator comprising an electric motor and means for determining a switching position of the rotary lever input part, and
- a restoration element which reverses said idle path when said counter-blocking member engages said blocking member.
A parking brake actuating device for a parking brake arrangement in a motor vehicle, said parking brake arrangement comprising a blocking member and a counter-blocking member, said actuating device comprising:
- a rotary lever arrangement which controls engagement of the blocking member with the counter-blocking member, said rotary lever arrangement comprising a rotary lever input part and a rotary lever output part which are rotatable relative to each other along an idle path when said blocking member is not engaged by said counter-blocking member, and a locking arrangement by which a plurality of defined switching states can be selected, said locking arrangement comprising at least one pretensioned locking device and a plurality of counter-locking devices, said locking device cooperating with a respective said counter-locking device in each of said switching states, and
- a restoration element which reverses said idle path when said counter-blocking member engages said blocking member.
A parking brake actuating device for a parking brake arrangement in a motor vehicle, said parking brake arrangement comprising a blocking member and a counter-blocking member, said actuating device comprising:
- a rotary lever arrangement which controls engagement of the blocking member with the counter-blocking member, said rotary lever arrangement comprising a rotary lever input part and a rotary lever output part which are rotatable relative to each other along an idle path when said blocking member is not engaged by said counter-blocking member, wherein the rotary lever input part and the rotary lever output part each have a pair of coupling surfaces which cooperate to define the idle path and enable a switching movement between the rotary lever input part and the rotary lever output part, and
- a restoration element which reverses said idle path when said counter-blocking member engages said blocking member.
