Abstract
A fail-safe drive () for an actuating drive is provided, which has a cam disc (), at least one restoring element, a counter-element () and an output shaft (), with the cam disc () and the counter-element () being configured for joint conversion of an axial movement of the restoring element along the output shaft () into a rotational movement of the output shaft (). The cam disc () has a control cam (), the profile of which is adapted to a spring characteristic curve of the restoring element such that, in the case of activation of the failsafe drive (), a constant output movement and/or a constant output torque can be generated.
