ABSTRACT:
A 6-way seat adjuster for motor vehicles in which a three armature motor is mounted on a slidable seat frame and has connections to front and rear lift devices on the frame and a horizontal adjuster. The motor is mounted on a transmission housing in which is located an integral spacer and bearing unit formed of a rigid low friction polymer. Each armature shaft of the motor has an integral primary driving worm adjacent its outer end, and each primary worm is in mesh with a primary worm gear. The primary worm gears are fixed to drive shafts to each of which is fixed a secondary driving worm in mesh with a secondary worm gear fixedly connected to a pinion. Two of the pinions are in mesh with toothed sectors provided on pivoted lift levers connected respectively to the front and rear edges of a vehicle seat. The third secondary worm gear is fixed to a drive shaft having a pinion fixedly connected thereto which cooperates with a stationary rack for moving the frame horizontally.
