The setting drive has an electric drive motor (1) and a conversion gearing (2), coupled to the resetting spring for tensioning the latter during the setting movement. A clutch (3) is provided between the motor and the gearing and released during the resetting movement, with simultaneous operation of a centrifugal braking device (4). The braking device has a rotatable brake pad carrier, with the brake pad (8) displaced radially by the centrifugal force, the brake pad carrier acting as part of the clutch and having a spine shaft (9) engaging a drive spline for the conversion gearing. |
