Abstract

A clutch-driven limited force actuator is disclosed having a motor (12), a planetary gear mechanism (20) in operative communication with the motor and a clutch plate (30). The clutch plate includes a contact surface selectively in frictional contact with the planetary gear mechanism to drive an actuator arm (34). In operation, the frictional force between the planetary gear mechanism and the clutch plate causes the actuator arm to actuate. The actuator arm can be connected to any element that requires actuation. The actuator of the present invention is preferably used in a wheelchair lift to actuate any mechanism that must have a safe limit on the amount of force applied to obstacles and that must have provision for direct manual operation.
