Abstract
A door presenter with a toothed clutch includes an extensible member that is controllable by a motor. The extensible member is driven by a lead screw, which is rotated by the motor via the toothed clutch to translate the extensible member. The toothed clutch includes a coupling disk and a coupling lever. The coupling disk is rotationally fixed to the lead screw, and the coupling lever is rotationally fixed to a drive gear driven by the motor. An axial load applied to the extensible member toward the toothed clutch causes rotation of the lead screw and coupling disk when the load exceeds a clutch disengagement threshold. The clutch will reengage after further relative rotation of the coupling disk and the coupling lever, which may occur in response to rotation of the lead screw or rotation of the coupling lever caused by actuation of the motor.
