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 an aircraft, comprising:
at least one front leg connectable to a structure of the aircraft; at least one rear leg connectable to the structure of the aircraft; at least one lateral bracket connecting between the front leg and to the rear leg, the lateral bracket having a lateral bracket front end and a lateral bracket rear end; a first track defined by the lateral bracket between the lateral bracket front end and the lateral bracket rear end; 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 seat pan having a seat pan front end and a seat pan rear end, the seat pan being slidingly connected to the first track adjacent to the seat pan 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 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 an upright position and a berth position.

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

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

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

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

6 . The aircraft divan of claim 1 , further comprising:
at least one front seat bracket pivotally connected adjacent to the lateral bracket front end, the front seat bracket slidingly engaging a third track extending between the seat pan front and the seat pan rear end; and 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 first track.

7 . The aircraft 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.

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

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

10 . The aircraft divan of claim 6 , wherein the at least one front seat bracket comprises a pair of front seat brackets spaced apart from one another.

11 . The aircraft divan of claim 6 , wherein the at least one rear seat bracket comprises a pair of rear seat brackets spaced apart from one another.

12 . The aircraft 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.

13 . The aircraft divan of claim 12 , 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.

14 . The aircraft divan of claim 13 , wherein the upright seating position is defined by the backrest at an angle between about 24° from a vertical line perpendicular to the floor and is defined by the seat at an angle between about 5° from a horizontal line parallel to the floor.

15 . The aircraft 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.

16 . The aircraft divan of claim 15 , 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.

17 . The aircraft divan of claim 16 , wherein the slouch seating position is defined by the backrest at an angle between about 35° from a vertical line perpendicular to the floor and is defined by the seat at an angle between about 10° from a horizontal line parallel to the floor.

18 . The aircraft divan of claim 1 , wherein the seat comprises:
a seat cushion disposed on the seat pan.

19 . The aircraft divan of claim 1 , wherein the backrest comprises:
a backrest plate; and a backrest cushion disposed on the backrest plate.

20 . The divan of claim 1 , wherein the front and rear legs are connectable to seating tracks disposed within the floor.
