ABSTRACT:
A seat adjuster for a vehicle seat assembly is disclosed in which a drive nut and drive screw are provided with the drive nut lugs and mounting bracket configured to enable assembly of the seat adjuster after the drive screw has been threaded onto the drive nut. The drive screw is a four start screw enabling the speed of rotation of the screw to be reduced while maintaining the operating speed of the seat adjuster. The reduced rotating speeds reduces sound emission during operation of the seat adjuster.
