Abstract
A vertical drive nut apparatus includes an elongated strap having an aperture formed in a central portion, and a pair of folded legs extending from the central portion and terminating in parallel first and second ends having coaxial apertures. A plastic drive nut is insert molded about the central portion of the strap with a threaded through bore in the drive nut coaxially aligned with the aperture in the central portion to threadingly receive a vertical drive lead screw. The first and second ends of the strap are pivotally connected to a bracket carried on a rotatable torsion tube extending between a pair of power seat adjuster track assemblies to effect rotation of the torsion tube and a resulting elevational change in one end of a seat upon translation of the drive nut and the strap by rotation of the vertical drive lead screw.
