Abstract
An electric actuator for a device which is to be actuated, having an electric-motor drive inputting its drive into a step-up gear mechanism, it being possible for the device to be driven via the step-up gear mechanism, in order to switch the device from a defined position into another defined position. A clutch element is connected after the step-up gear mechanism so that the device which is to be actuated can be driven by the step-up gear mechanism with the clutch element connected in between. The clutch element decouples the step-up gear mechanism from the device in the event of a failure of the current supply or voltage supply for the actuator, with the result that a defined basic position or rest position can be assumed automatically by the device which is to be actuated.
