A fabric air duct of an HVAC system includes a discharge air register with an air deflector that extends along the length of the duct. Rotating or twisting the deflector adjusts the volume and/or direction of the air being discharged from the register. Even though the deflector is disposed inside the duct, the deflector can be twisted or rotated by manipulating the exterior fabric wall of the duct.

1. An air duct assembly, comprising:an air duct having a pliable wall that defines a plurality of openings for discharging air therethrough; and an air deflector disposed within the air duct, urged up against the pliable wall, being adjacent to the plurality of openings, having a longitudinal center
1. An air duct assembly, comprising:an air duct having a pliable wall that defines a plurality of openings for discharging air therethrough; and an air deflector disposed within the air duct, urged up against the pliable wall, being adjacent to the plurality of openings, having a longitudinal centerline, and being rotatable about its longitudinal centerline to help determine in which direction the air passes through the plurality of openings. 2. The air duct assembly of claim 1, wherein the air deflector defines a plurality of holes for directing air therethrough.3. The air duct assembly of claim 2, wherein the air deflector has a major thickness and a minor thickness that provides the air deflector with an oblong cross-sectional area.4. The air duct assembly of claim 3, wherein the plurality of holes run through the minor thickness.5. The air duct assembly of claim 1, further comprising a pliable strip attached to the pliable wall to define a sheath that contains the air deflector between the pliable strip and the pliable wall.6. The air duct assembly of claim 5, wherein the pliable strip comprises a fabric mesh.7. The air duct assembly of claim 5, wherein the pliable strip provides less airflow resistance than does the plurality of openings.8. The air duct assembly of claim 1, wherein the air deflector is twistable about itself to vary, along a length of the air duct, the direction that the air passes through the plurality of openings.9. The air duct assembly of claim 1, wherein the air deflector comprises a plurality of air defector segments that are disposed end-to-end.10. The air duct assembly of claim 1, wherein the air deflector comprises a plurality of air defector segments that are spaced apart from each other.11. An air duct assembly, comprising:an air duct having a pliable wall that defines a plurality of openings for discharging air therethrough; a pliable strip attached to the pliable wall and being air permeable; and an air deflector disposed between the pliable strip and the pliable wall, wherein the air deflector is movable for changing a direction that the air passes through the plurality of openings. 12. The air duct assembly of claim 11, wherein the air deflector defines a plurality of holes for directing air therethrough.13. The air duct assembly of claim 12, wherein the air deflector has a major thickness and a minor thickness that provides the air deflector with an oblong cross-sectional area.14. The air duct assembly of claim 12, wherein the plurality of holes run through the minor thickness.15. The air duct assembly of claim 14, wherein the pliable strip comprises a fabric mesh.16. The air duct assembly of claim 11, wherein the air deflector is twistable about itself to vary, along a length of the air duct, the direction that the air passes through the plurality of openings.17. The air duct assembly of claim 11, wherein the air deflector comprises a plurality of air defector segments that are disposed end-to-end.18. The air duct assembly of claim 11, wherein the air deflector comprises a plurality of air defector segments that are spaced apart from each other.19. The air duct assembly of claim 11, wherein the pliable strip is disposed inside the air duct.20. The air duct assembly of claim 11, wherein the air deflector is disposed inside the air duct.21. A method of redirecting airflow through a pliable wall of an air duct that contains an air deflector, comprising: repositioning the air deflector by manipulating the pliable wall.22. The method of claim 21, further comprising rotating the air deflector about a longitude centerline thereof.23. The method of claim 21, further comprising twisting the air deflector about itself.24. The method of claim 21, further comprising containing the air deflector between the pliable wall and a pliable strip that is attached to the pliable wall.25. The method of claim 21, further comprising conveying air through a plurality of holes in the deflector.26. The method of claim 21, further comprising pressing the air deflector up against an interior surface of the pliable wall.
