Abstract
In at least some implementations, a multiple position actuator, includes a motor, a gearset driven by the motor, an output driven by the gearset between at least two positions, and a clutch arranged between the gearset and the output to permit relative rotation between the output and gearset. The gearset, output and clutch may be coaxially arranged. The clutch may include at least two movable elements that move relative to one or both of the output and gearset to permit relative rotation between the clutch and gearset in two opposed rotational directions. In at least some implementations, the gearset provides a torque to the output that is at least 50 times greater than the torque of the motor.
