The invention relates to a brake device for producing a brake torque counter to a torque acting on a rotatably supported member, wherein the brake device has:at least one toothed brake ring which is mechanically actively connected to the rotatably supported or supportable member,a plurality of bending-resistant brake levers which each have at a first lever end at least one stop which engages in the tooth arrangement of the brake ring and which are each rotatably supported on a second lever end opposite the first lever end,wherein each brake lever is connected to a force element for applying a brake force in such a manner that, as a result of the brake force via the stop of the respective brake lever which is in engagement with the tooth arrangement of the brake ring, a brake torque is produced on the brake ring tangentially counter to the active direction of the torque in order to apply a brake torque to the rotatably supported or supportable member,wherein the brake levers are arranged with respect to the toothed brake ring in such a manner that, during a rollover of a brake lever, in which the stop of the respective brake lever engages in a subsequent tooth flank of the tooth arrangement, all remaining brake levers with their respective stops remain in engagement with their respective tooth flank of the tooth arrangement.
