Abstract

A curtain divider for an aircraft interior containing pivot stow bins includes a first fabric curtain, having an outboard end and an inboard end, which is attachable to the aircraft interior only at the outboard and inboard ends. The first fabric curtain includes a vertical portion, and a horizontal portion. The vertical portion has a substantially straight bottom edge, and an arcuate top edge defining a space sufficient for opening the pivot stow bins. The horizontal portion is flexibly attached to the vertical portion along the top edge and extends from the outboard end to the inboard end, having a substantially continuous curvature. The horizontal portion is adapted to impart forward and aft stability to the curtain support member at the top edge.

Claims

1. A curtain divider for an aircraft interior containing pivot stow bins, comprising:

a first fabric curtain, having;

an outboard end and an inboard end, being attachable to the aircraft interior only at the outboard and inboard ends;

a substantially planar vertical portion, having a substantially straight bottom edge, and an arcuate top edge defining a space sufficient for opening the pivot stow bins; and

a substantially planar flange portion, oriented substantially perpendicular to the plane of the vertical portion and flexibly attached to the vertical portion along the top edge and extending from the outboard end to the inboard end, having a substantially continuous curvature, adapted to impart forward and aft stability to the first fabric curtain at the top edge.

2. A curtain divider in accordance with claim 1, further comprising:

a flexible track device, disposed along the bottom edge;

a plurality of sliding elements, slidingly disposed along the flexible track device; and

a second fabric curtain, attached to the sliding elements.

3. A curtain divider in accordance with claim 2, wherein the flexible track device comprises a zipper chain.

4. A curtain divider in accordance with claim 2, wherein the second curtain has a length sufficient to extend below a top of a back of an aircraft seat when the seat is in a fully reclined position.

5. A curtain divider in accordance with claim 1, wherein the first curtain has a length sufficient to extend below a top of a back of an aircraft seat when the seat is in a fully reclined position.

6. A curtain divider in accordance with claim 1, further comprising a stiffener, disposed within the vertical portion and extending along the top edge.

7. A curtain divider in accordance with claim 6, wherein the stiffener comprises a fiberglass panel.

8. A curtain divider in accordance with claim 6, wherein the stiffener includes a tail, extending generally downwardly at the outboard end, configured to hold the outboard end of the first curtain generally against a curved sidewall of the aircraft interior.

9. A curtain divider in accordance with claim 8, wherein the stiffener comprises a central stiffener panel and a pair of outer stiffener panels, disposed on opposite sides of the central stiffener panel, and further comprising a tail stiffener, attached to the tail of the central stiffener panel and disposed inwardly of the outer stiffener panels.

10. A curtain divider in accordance with claim 1, wherein the flange portion is flexibly attached to an internal stiffener, and the vertical portion comprises a fabric covering, removably attachable to the internal stiffener.

11. An aircraft having an interior with pivot stow bins and a curtain divider, the curtain divider comprising:

a substantially vertical fabric panel, having an outboard end, an inboard end, a substantially straight bottom edge, an arcuate top edge defining an opening space for the pivot stow bins, the panel being attachable to the aircraft interior at the inboard end inboard of a pivot stow bin, and at the outboard end near a sidewall of the aircraft; and

a substantially planar top flange, disposed along the top edge of the panel and oriented substantially perpendicular thereto, the panel fabric enclosing and flexibly attaching the fabric panel and the top flange as an integral unit, the top flange having an unsupported span between the outboard end and the inboard end and defining a lower boundary of a space suitable for opening the pivot stow bins.

12. An aircraft in accordance with claim 11, wherein the fabric panel includes a tail, extending generally downwardly at the outboard end, configured to hold the outboard end of the fabric panel near the sidewall of the aircraft interior.

13. An aircraft in accordance with claim 12, further comprising:

a central stiffener, disposed within the vertical fabric panel and attached to the top flange along the top edge, the central stiffener including a tail portion disposed within the tail of the fabric panel;

a tail stiffener, attached to the tail portion; and

a pair of outer stiffeners, disposed within the fabric panel on opposite sides of the central stiffener.

14. An aircraft in accordance with claim 11, wherein the fabric panel has a length sufficient to extend below a top of a back of an aircraft seat when the seat is in a fully reclined position.

15. An aircraft in accordance with claim 11, further comprising:

a flexible track device, disposed along the bottom edge of the panel; and

a curtain, slidably attached to and descending from the flexible track device.

16. An aircraft in accordance with claim 15, wherein the flexible track device comprises a zipper track, and the curtain is slidably attached to the flexible track device via a plurality of zipper sliders.

17. A method for creating a curtain divider for an aircraft interior containing pivot stow bins, comprising:

creating a vertical panel having a curved upper edge defining a lower boundary of a space suitable for opening the pivot stow bins, and a substantially straight lower edge;

flexibly attaching a substantially planar top flange of fabric material substantially perpendicularly to the vertical panel within a fabric sleeve along the upper edge; and

attaching connectors to inboard and outboard ends, respectively, of the curved upper edge, the connectors being the sole attachment points to attach the vertical panel to the aircraft interior.

18. A method in accordance with claim 17, further comprising creating a tail, extending generally downwardly at the outboard end of the curtain support member, configured to hold the outboard end of the curtain support member against a sidewall of the aircraft interior.

19. A method in accordance with claim 17, further comprising:

affixing a plurality of zipper sliders to a zipper chain;

affixing the zipper chain to the lower edge of the vertical panel; and

engaging the zipper slider teeth with a flexible curtain.

20. A method in accordance with claim 17, further comprising removably attaching a decorative fabric covering to the vertical panel.
