Abstract
A drive assembly for a seat adjuster is used to adjust the longitudinal position of a vehicle seat between a plurality of positions. The drive assembly includes a first track mounted to a vehicle structure a second track that is supported for longitudinal movement relative to the first track. A bracket is fixed relative to the first track and has an opening through which a drive nut is inserted. The drive nut has a threaded central bore and is rotatable between a first position and a second position. In the first position the drive nut moves relative to the bracket through the opening. In the second position the drive nut contacts the bracket to form a positive structural engagement between the drive nut and the bracket. A screw shaft has an elongated body with an external threaded surface that engages the threaded central bore in the drive nut to move the second track between a plurality of adjusted positions relative to the first track. A drive motor is used to drive the screw shaft relative to the drive nut only when the drive nut is moved from the first position to the second position.
