ABSTRACT:
An improved gear train for the adjustment structure in a mirror includes a slip clutch disk connection that allows a pinion gear to rotate relative to an intermediate gear reduction. The pinion gear is engaged to rotate a rack, and the rack is connected to the mirror to adjust the position of the mirror. The rack is spring biased into engagement with the pinion, thus insuring that the two move with each other quietly and smoothly. The rack can be biased into engagement with the pinion gear, since it need not be able to slip relative to the pinion gear, as was the case in the prior art. The clutch disk allows the pinion gear to move with the rack when the mirror is manually adjusted. The inventive clutch disk is relatively simple, including a clutch drive gear rotatably journaled on a drive shaft. The drive shaft is fixed to rotate with the pinion gear. A spring biases a friction face of the clutch drive gear into engagement with the clutch disk, which also rotates with the pinion gear. Since the pinion gear may slip relative to the clutch drive gear, but will always move with the rack, a memory feedback position control can sense the rotational position of the pinion gear and provide an accurate indication of the actual position of the rack, and hence the mirror.
