Abstract:
A resetting device for resetting an actuator for actuating a safety gear of an elevator includes an actuation spring to be brought into a compressed state by a resetting force, an electric motor for providing the resetting force and a transmission for transmitting the resetting force of the electric motor to the actuation spring. The transmission provides a positive gear ratio.
