Abstract

An implementation of a contoured class divider for dividing an aircraft cabin includes a panel positioned between an aft seat and a forward seat, the panel having an aft-facing convex contour closely matching an aft-facing contour of a seatback of the forward seat and configured to enhance space utilization. The contoured class divider may include an articulation system to articulate at least a portion of the panel from a first position (normal operation) to a second position (emergency landing). The contoured class divider may provide up to an additional 12 inches of space which can be used to reduce seat pitch (and thereby enhance passenger comfort) or increase the number of rows of seats on a given aircraft.

First claim

What is claimed is:

1. A contoured class divider for dividing an aircraft cabin arrangement between at least one forward passenger seat and at least one aft passenger seat, the contoured class divider comprising:
a panel positioned adjacent to and rearwardly of the at least one forward seat, the panel having a contoured shape for receiving the back of the forward passenger seat in at least one of a reclined position and an upright position, the panel extending substantially from an underside of an overhead bin to a lower support assembly, wherein the lower support assembly includes a pair of contoured support legs supporting a lower edge of the panel, wherein the contoured support legs extend downward from the lower edge of the panel to a respective pivot point, wherein the lower edge of the panel is above a floor of the aircraft cabin such that a passenger in the aft passenger seat is able to stow luggage beneath the forward passenger seat, passing the luggage between the respective pivot point of each contoured support leg and below the lower edge of the panel, wherein the lower edge of the panel is closer to a level of a seat bottom of the at least one forward seat than to a level of the floor; and
wherein the respective pivot point is configured to articulate the panel from a rearward position during normal operation to a forward position during emergency landing, wherein the respective pivot point is closer to the level of the floor than to the level of the seat bottom.

2. The contoured class divider of claim 1 , wherein the respective pivot point includes a shear pin.

3. The contoured class divider of claim 1 , wherein the respective pivot point includes a spring biasing the contoured class divider into the forward or rearward position.

4. The contoured class divider of claim 1 , wherein the respective pivot point articulates the panel to the forward position when the panel is subjected to a deceleration of greater than 16 G.

5. The contoured class divider of claim 1 , wherein the lower support assembly is mounted in a floor track of the cabin.

6. The contoured class divider of claim 1 , wherein the panel includes two segments which pivot relative to one another.

7. The contoured class divider of claim 1 , wherein the panel is located within one inch of the at least one forward passenger seat when the at least one forward passenger seat is in a take-off taxi and landing (TTOL) operational position.

8. The contoured class divider of claim 1 , wherein the panel includes at least one energy absorbing zone to absorb the energy of a head impact.

9. The contoured class divider of claim 1 , wherein the panel and the at least one forward seat are configured to share loads during emergency landing.

10. A method for dividing an aircraft cabin arrangement between at least one forward passenger seat and at least one aft passenger seat, the method comprising:
positioning a panel of a contoured class divider adjacent to and rearwardly of the at least one forward seat, the panel having a contoured shape for receiving the back of the forward seat in at least one of a reclined position and an upright position;
fixing a lower support assembly of the contoured class divider to a structure of a floor of the cabin, wherein the panel extends substantially from an underside of an overhead bin to the lower support assembly, wherein the lower support assembly includes a pair of contoured support legs supporting a lower edge of the panel, wherein the contoured support legs extend downward from the lower edge of the panel to a respective pivot point, wherein the panel is above a floor of the aircraft cabin such that a passenger in the aft seat is configured to stow luggage beneath the forward passenger seat by passing the luggage between the respective pivot points, wherein the lower edge is closer to a level of a seat bottom of the at least one forward seat than to a level of the floor; and
connecting an upper edge of the panel to an articulation mechanism, wherein the articulation mechanism causes the panel to articulate during emergency landing from a rearward position used during normal operation to a forward position, and upon connection, the panel extends substantially from an underside of an overhead bin to the lower support assembly, including a pivot closer to the level of the floor than to the level of the seat bottom.

11. The method of claim 10 , wherein the upper edge of the panel is connected to the articulation mechanism via a shear pin extending upward from the upper edge of the panel.

12. The method of claim 10 , wherein the articulation mechanism is configured to withstand deceleration of less than 16 G without articulating the panel.

13. The method of claim 10 , wherein the structure of the floor of the cabin is a floor track.

14. The method of claim 10 , wherein positioning the panel comprises positioning the panel in the rearward position within one inch of a recline position of the at least one forward passenger seat.

15. The method of claim 10 , wherein positioning the panel comprises positioning the panel in the rearward position within a head impact zone of an aft-seated passenger in the at least one aft passenger seat, wherein the panel comprises at least one head impact zone protection feature.

16. The method of claim 15 , wherein the at least one head impact zone protection feature comprises energy absorbing material embedded in a portion of the panel within the head impact zone.

17. The method of claim 10 , wherein positioning the panel comprises positioning the panel such that, upon articulation, the panel is positioned to contact the at least one forward seat.

18. The method of claim 10 , further comprising:
prior to positioning the panel, removing a class divider from between the at least one forward passenger seat and the at least one aft passenger seat; and
relocating the at least one aft passenger seat at least 4 inches closer to the at least one forward passenger seat.

19. The method of claim 10 , wherein the articulation mechanism is built into the overhead bin.
