Automotive parking brake and parking brake system for motor vehicles
First Claim
1. An electrically actuatable automotive parking brake with mechanical emergency actuation, characterized in that the parking brake is one of a disk brake (10) including brake pads (52, 54) and a drum brake (10'"'"') including brake shoes (110, 112) which can be applied and released by means of a gear arrangement (100) which is arranged at the brake and which comprises one power input and one power output, with the power input of the gear arrangement (100) being coupled with one end of a flexible shaft (58), the other end of which is arranged remote from the brake and is adapted to be coupled with a manual crank (66), in order to be able to mechanically actuate the parking brake in the case of a failure of the electrical actuation.

Abstract
In order to improve an electrically actuatable automotive parking brake with mechanical emergency actuation, the brake pads (52, 54) of the parking brake, which may be either a disk brake or a drum brake, can be applied or released via gear arrangement (100) arranged within or at the brake. The gear arrangement (100) has one power input and one power output, with the power input being coupled with the one end of a flexible shaft, the other end of which being arranged remote from the brake can be coupled with a manual crank, in order to be able to actuate the parking brake mechanically in the case of a failure of the electric actuation.
