Abstract

A gear assembly for a seat adjuster includes: a gear housing, a worm, a helical gear meshing with the worm, an oscillating gear carried on an eccentric lobe of the helical gear, a pinion plate, a first gear disposed in the gear housing. A ring gear, a second ring gear disposed in the pinion plate, and a pinion member carrying the helical gear and the pinion plate. The oscillating gear includes a first set of oscillating gear teeth and a second set of oscillating gear teeth meshing with the first and second ring gears, respectively. A case-side gear ring disposed in the gear housing defines a portion of the first ring gear, and the gear housing defines another portion of the first ring gear. The pinion plate defines a second ring gear.
