Abstract

A seat adjuster assembly for a vehicle seat assembly may include a housing, a worm, a spindle screw, a motor, and either a helical gear or a single-enveloping worm gear. The worm may be disposed within the housing for rotation about a first axis and having a thread. The helical gear or single-enveloping worm gear may be disposed within the housing for rotation about a second axis and meshingly-engaged with a pitch surface of the thread of the worm. The spindle screw may extend along the second axis and through the housing and the helical gear or single-enveloping worm gear. The spindle screw may be meshingly-engaged with the helical gear or single-enveloping worm gear. The motor may drive the worm to cause linear movement of the housing, worm, motor, and the helical gear or single-enveloping worm gear along the second axis.
