Abstract
An actuator assembly includes an actuator drivingly connected to a gear wheel. The gear wheel includes an abutment secured rotationally fast having a camming surface and operable to drive an output member. The actuator assembly is operable to apply a force in a first direction to drive the output member in the first direction from a rest condition to an actuated condition and is operable to apply a force in a second direction to drive the output member in the second direction from the actuated condition to the rest condition. Movement of the output member in the second direction stores energy in the energy storage device, and movement of the output member in the first direction is assisted by the energy storage device. When the actuator assembly is in the rest condition, a detent engages the energy storage device to releasably retain the energy storage device in a rest position. Actuation of the actuator causes the camming surface to disengage the detent from the energy storage device to allow the energy storage device to assist movement of the output member in the first direction.
