the interior body trim panel includes a seatbelt attachment opening for attaching a seatbelt.

11. The interior body trim arrangement according to claim 10 , wherein

the seatbelt attachment opening is formed in a central area between upper and lower edges of the interior body trim panel, and offset laterally with respect to the integrated HVAC duct such that the seatbelt attachment opening does not extend into the integrated HVAC duct.

12. The interior body trim arrangement according to claim 1 , wherein

the interior body trim panel has first and second duct sections that are vertically oriented when the interior body trim arrangement is installed, with the second duct section being angularly arranged in a non-coplanar manner with respect to the first duct section to define a vertically oriented corner of the integrated HVAC duct.

13. The interior body trim arrangement according to claim 12 , wherein

the back closure member includes first and second edge connections that are vertically oriented when the interior body trim arrangement is installed, with the first edge connection being secured to the outboard facing surface of the interior body trim panel at the first duct section and the second edge connection being secured to the outboard facing surface of the interior body trim panel at the second duct section.

14. The interior body trim arrangement according to claim 13 , wherein

the interior body trim panel further includes a B-pillar section extending from the first duct section such that the first edge connection is connected to a central area of the interior body trim panel as measured in a horizontal direction between the vertically oriented corner of the integrated HVAC duct and a vertically oriented free edge of the B-pillar section.

15. The interior body trim arrangement according to claim 13 , wherein the second edge connection is attached to a step portion of the second duct section of the interior body trim panel.

16. The interior body trim arrangement according to claim 15 , wherein the back closure member includes first and second attachment flanges, with the first attachment flange forming the first edge connection and the second attachment flange forming the second edge connection, and with the first and second attachment flanges extending substantially parallel to one another.

17. The interior body trim arrangement according to claim 1 , further comprising

a lower duct coupled to the second opening end of the integrated HVAC duct when the interior body trim arrangement is installed to a vehicle, with the lower duct and the second opening end of the integrated HVAC duct being matingly configured such that the lower duct is movable in a longitudinal direction of the integrated HVAC duct for connection to the second opening end of the integrated HVAC duct prior to installation of the lower duct to the vehicle.

18. The interior body trim arrangement according to claim 1 , wherein

the interior body trim panel includes a U-shaped component with first and second interior corners, and

the back closure member includes an L-shaped component that mates with the interior body trim panel to define the integrated HVAC duct at one of the first and second interior corners.

19. The interior body trim arrangement according to claim 1 , wherein

the interior facing surface of the interior body trim panel continuously extends along the integrated HVAC duct.

20. A vehicle comprising:

a vehicle body structure having a structural pillar that defines a passenger compartment of the vehicle;

an interior body trim panel fixed to the vehicle body structure, the interior body trim panel having an interior facing surface and an outboard facing surface opposite the interior facing surface, the outboard facing surface of the interior body trim panel defining a cavity when the interior body trim panel is installed to the vehicle body structure; and
