Abstract
A vehicle seating assembly is provided which includes a seat back and a seat base operably connected to the seat back. The seat base has a seat base frame that includes a torsion tube extending laterally between at least two side members. A height adjustment mechanism is disposed through at least one of the side members. A torsion spring extends within the torsion tube and is in contact with at least two side members. A torsion spring bushing is positioned around the torsion spring and extends into the torsion tube. The torsion spring bushing defines a brush configured to contact the torsion tube and a retaining ring positioned around the torsion tube. The retaining ring is in contact with at least one side member.
