Abstract
A single-stage gear reduction output mechanism for an automotive seat assembly including a gear housing bracket, gear housing, axle shaft, eccentric, and first and second gears. The axle shaft extends through the eccentric with a slip fit, the first gear rotates with the axle shaft, and the second gear is carried on a first bearing surface of the eccentric and meshingly engages the first gear in a planetary arrangement. A locking plate including first, second, and third slot cutouts is disposed within the gear housing. A support pin extends from the gear housing through the first slot cutout and a second bearing surface of the eccentric extends through the second slot cutout to support the locking plate and limit its movement along a lateral axis. The second gear includes a first pin that extends through the third slot cutout to prevent the first gear from back-driving the second gear.
