摘要： A rotational friction brake actuated and regulated by the rate of change of the angular speed is disclosed. The rotational friction brake includes a first body and a second body rotationally attached to the first body. The second body is arranged to rotate around a rotational center axis of the second body. An actuator arrangement is configured to move a second friction surface into frictional engagement with a first friction surface. The actuator arrangement includes an actuator arm pivotably attached to the second body in a pivot point that is eccentrically offset to the rotational center axis. The actuator arrangement has a radius of gyration (RG) longer than a distance from the pivot point to the rotational center axis. The actuator arrangement has an internal flexibility which allows its shape to depend on centrifugal forces. A fishing reel comprising such a rotational friction brake is also disclosed.
