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.

A vehicle seating assembly comprising: a seat back; anda seat base operably connected to the seat back, the seat base having a seat base frame comprising: a torsion tube extending laterally between at least two side members;a height adjustment mechanism disposed through at least one of the side m
1. A vehicle seating assembly comprising: a seat back; anda seat base operably connected to the seat back, the seat base having a seat base frame comprising: a torsion tube extending laterally between at least two side members;a height adjustment mechanism disposed through at least one of the side members;a torsion spring extending within the torsion tube and in contact with at least two side members;a torsion spring bushing positioned around the torsion spring and extending into the torsion tube, the torsion spring bushing comprising a brush configured to contact the torsion tube; anda retaining ring positioned around the torsion tube, the retaining ring in contact with at least one side member. 2. The vehicle seating assembly of claim 1, wherein the torsion spring bushing comprises a polymeric material. 3. The vehicle seating assembly of claim 1, wherein the retaining ring defines an angled portion. 4. The vehicle seating assembly of claim 1, wherein the torsion spring bushing is configured to center the torsion spring within the torsion tube. 5. The vehicle seating assembly of claim 1, wherein the torsion spring bushing defines a plurality of brushes. 6. The vehicle seating assembly of claim 5, wherein the plurality of brushes are configured to resist lateral and rotational movement of the torsion spring bushing within the torsion tube. 7. A vehicle seat base comprising: a seat base frame having a torsion tube extending laterally between at least two side members;a torsion spring extending within the torsion tube and in contact with both side members; anda torsion spring bushing positioned around the torsion spring and extending into the torsion tube, the torsion spring bushing comprising a plurality of protruding brushes configured to engage the torsion tube. 8. The vehicle seat base of claim 7, wherein the bushing defines an annulus around which a plurality of protrusions is defined. 9. The vehicle seat base of claim 8, wherein the plurality of brushes are positioned on the plurality of protrusions. 10. The vehicle seat base of claim 7, wherein the plurality of brushes are equally spaced on the torsion spring bushing. 11. The vehicle seat base of claim 7, wherein the plurality of brushes extend on the torsion spring bushing laterally relative to the torsion tube. 12. The vehicle seat base of claim 7, wherein each of the plurality of brushes comprise a plurality of fibers. 13. The vehicle seat base of claim 12, wherein the plurality of fibers comprise a polymeric material. 14. A vehicle seat base comprising: a seat base frame having a torsion tube extending laterally between at least two side members;a torsion spring extending within the torsion tube; anda torsion spring bushing positioned around the torsion spring and extending into the torsion tube, the torsion spring bushing comprising a hinge and a fastener disposed on opposite sides of the torsion spring bushing. 15. The vehicle seat base of claim 14, wherein the hinge of the torsion spring bushing is configured to allow the bushing to open and close. 16. The vehicle seat base of claim 14, wherein the hinge of the bushing is a living hinge. 17. The vehicle seat base of claim 14, further comprising: an alignment feature defined by the torsion spring bushing, wherein the hinge is positioned within the alignment feature. 18. The vehicle seat base of claim 14, wherein the alignment feature is generally V-shaped. 19. The vehicle seat base of claim 18, wherein the fastener a snap feature. 20. The vehicle seat base of claim 14, wherein the bushing defines an annulus having a curved conical shape.
