Abstract

An aircraft divan includes a lateral bracket connecting between front and rear legs with lateral bracket front and rear ends, a first track defined by the lateral bracket between the lateral bracket front and rear ends, an upright, having upright top and bottom ends, a second track defined by the upright between the upright top and bottom ends, a seat pan having seat pan front and rear ends, the seat pan being slidingly connected to the first track adjacent to the seat pan rear end, and a backrest having backrest top and bottom ends, the backrest being slidingly connected to the second track adjacent to the backrest top end. The seat pan rear end is pivotably connected to the backrest adjacent to the backrest bottom end such that movement of the seat pan is transmitted to the backrest so as to move together between upright and berth positions.

First claim

What is claimed is:

1. A divan for a vehicle, comprising:
an undercarriage comprising at least one lateral bracket, the lateral bracket having a lateral bracket front end and a lateral bracket rear end;
a seat pan having a seat pan front end and a seat pan rear end, the seat pan comprising a first track extending between the seat pan front end and the seat pan rear end of the seat pan;
at least one forward seat bracket pivotally connected adjacent to the lateral bracket front end and slidingly engaging the first track;
at least one upright, having an upright top end and an upright bottom end;
a second track defined by the upright between the upright top end and the upright bottom end;
a third track defined by the lateral bracket between the lateral bracket front end and the lateral bracket rear end; and
a backrest having a backrest top end and a backrest bottom end, the backrest being slidingly connected to the second track adjacent to the backrest top end,
wherein the seat pan is slidingly connected to the third track adjacent to the seat pan rear end, the forward seat bracket pivots upon displacement of the seat pan between a divan upright seating position and a divan slouch seating position, and the seat pan rear end is pivotally connected to the backrest adjacent to the backrest bottom end such that movement of the seat pan is transmitted to the backrest so as to move together between the upright seating position and the slouch seating position.

2. The divan of claim 1 , wherein the upright bottom end is connected to the lateral bracket rear end.

3. The divan of claim 1 , wherein the third track defines at least three seating positions, the upright seating position for taxi, take-off, and landing, the slouch seating position, and a berth seating position.

4. The divan of claim 3 , wherein the third track is essentially V-shaped with a first end defining the upright seating position, an intermediate dip defining the slouch seating position, and a second end defining the berth seating position.

5. The divan of claim 4 , wherein a position of the rear end of the seat pan follows the shape of the third track.

6. The divan of claim 3 , wherein the upright seating position is defined by the backrest at an angle between about 19-29° from a vertical line perpendicular to a floor of the aircraft and is defined by the seat at an angle between about 0-10° from a horizontal line parallel to the floor.

7. The divan of claim 6 , wherein the upright seating position is defined by the backrest at an angle between about 21.5-26.5° from a vertical line perpendicular to the floor and is defined by the seat at an angle between about 2.5-7.5° from a horizontal line parallel to the floor.

8. The divan of claim 7 , wherein the upright seating position is defined by the backrest at an angle about 24° from a vertical line perpendicular to the floor and is defined by the seat at an angle about 5° from a horizontal line parallel to the floor.

9. The divan of claim 3 , wherein the slouch seating position is defined by the backrest at an angle between about 30-40° from a vertical line perpendicular to the floor and is defined by the seat at an angle between about 5-15° from a horizontal line parallel to the floor.

10. The divan of claim 9 , wherein the slouch seating position is defined by the backrest at an angle between about 32.5-37.5° from a vertical line perpendicular to the floor and is defined by the seat at an angle between about 7.5-12.5° from a horizontal line parallel to the floor.

11. The divan of claim 10 , wherein the slouch seating position is defined by the backrest at an angle about 35° from a vertical line perpendicular to the floor and is defined by the seat at an angle about 10° from a horizontal line parallel to the floor.

12. The divan of claim 1 , further comprising:
at least one rear seat bracket connected, at a first end, adjacent to the seat pan rear end and, at a second end, slidingly engaging the third track.

13. The divan of claim 12 , wherein the at least one rear seat bracket comprises a pair of rear seat brackets spaced apart from one another.

14. The divan of claim 1 , further comprising:
at least one backrest bracket, at one end, being connected adjacent to the backrest top end and, at the other end, slidingly engaging the second track.

15. The divan of claim 1 , wherein the at least one lateral bracket comprises a pair of lateral brackets spaced apart from one another.

16. The divan of claim 1 , wherein the at least one upright comprises a pair of uprights spaced apart from one another.

17. The divan of claim 1 , wherein the at least one forward seat bracket comprises a pair of forward seat brackets spaced apart from one another.

18. A divan, comprising:
an undercarriage comprising at least one lateral bracket, the lateral bracket having a lateral bracket front end and a lateral bracket rear end;
a seat pan pivotally and slidingly connected to the lateral bracket front end, the seat pan having a seat pan front end and a seat pan rear end;
a first track extending between the seat pan front end and the seat pan rear end of the seat pan;
at least one forward seat bracket pivotally connected adjacent to the lateral bracket front end and slidingly engaging the first track;
at least one upright, having an upright top end and an upright bottom end;
a second track defined by the upright between the upright top end and the upright bottom end;
a third track defined by the lateral bracket between the lateral bracket front end and the lateral bracket rear end; and
a backrest having a backrest top end and a backrest bottom end, the backrest being slidingly connected to the second track adjacent to the backrest top end;
wherein the seat pan is slidingly connected to the third track adjacent to the seat pan rear end,
wherein upon displacement of the seat pan between a divan upright seating position and a divan slouch seating position, the seat pan pivots and slides with respect to the lateral bracket front end, and the forward seat bracket pivots, and
wherein the seat pan rear end is pivotally connected to the backrest adjacent to the backrest bottom end such that movement of the seat pan is transmitted to the backrest so as to move together between the upright seating position and the slouch seating position.

19. The divan of claim 18 , wherein the upright bottom end is connected to the lateral bracket rear end.

20. The divan of claim 18 , wherein the third track defines at least three seating positions, the upright seating position for taxi, take-off, and landing, the slouch seating position, and a berth seating position.

21. The divan of claim 20 , wherein the third track is essentially V-shaped with a first end defining the upright seating position, an intermediate dip defining the slouch seating position, and a second end defining the berth seating position.

22. The divan of claim 21 , wherein a position of the rear end of the seat pan follows the shape of the third track.

23. The divan of claim 20 , wherein the upright seating position is defined by the backrest at an angle between about 19-29° from a vertical line perpendicular to a floor of the aircraft and is defined by the seat at an angle between about 0-10° from a horizontal line parallel to the floor.

24. The divan of claim 23 , wherein the upright seating position is defined by the backrest at an angle between about 21.5-26.5° from a vertical line perpendicu
