Abstract

A seating arrangement includes a seat with a seating surface and a top bunk disposed adjacent to the seat. The seat and the top bunk are configurable between a first configuration and a second configuration. In the first configuration, the seat accommodates a user in a seated position and the top bunk is stowed. In the second configuration, the seat and the top bunk form a bunk bed configured to accommodate users in prone positions. In the first configuration, the seating surface is disposed at a first predetermined height. In addition, in the second configuration, the seating surface is disposed at a second predetermined height that is lower than the first predetermined height.

First claim

What is claimed is:

1. A seating arrangement, comprising:
a seat including a seating surface and a back rest with a bottom end and a top end, the bottom end being connected to and moveable in relation to a rear end of the seating surface; and
a top bunk,
wherein the seat and the top bunk are configurable between a first configuration and a second configuration,
wherein, in the first configuration, the seat accommodates a user in a seated position and the top bunk is stowed adjacent to a side surface of the seat,
wherein, in the second configuration, the seat and the top bunk form a bunk bed configured to accommodate users in prone positions,
wherein, in the first configuration, the seating surface is disposed at a first predetermined height, and
wherein, in the second configuration, the seating surface is disposed at a second predetermined height that is lower than the first predetermined height.

2. The seating arrangement of claim 1 , wherein the seat further comprises:
a leg rest connected to and moveable in relation to a front end of the seating surface;
a head rest connected to and moveable in relation to the top end of the back rest.

3. The seating arrangement of claim 1 , further comprising:
armrests pivotally attached to respective sides of the back rest.

4. The seating arrangement of claim 3 , wherein the back rest and armrests are configured such that the back rest and armrests form a contiguous surface when the armrests are folded adjacent to the back rest.

5. The seating arrangement of claim 3 , wherein the back rest and the armrests are configured to form a contiguous surface, establishing part of a lower bunk, when the seat is in the second configuration.

6. The seating arrangement of claim 1 , further comprising:
at least two vertical supports extending upwardly adjacent to the seat, the two vertical supports being pivotally connected to the top bunk to permit the top bunk to pivot between the first and second configurations.

7. The seating arrangement of claim 1 , wherein the seat and the top bunk are attachable to tracks in a floor supporting the seat and the top bunk.

8. The seating arrangement of claim 1 , further comprising:
an ottoman disposed a predetermined distance from the seat,
wherein the ottoman includes an ottoman cushion,
wherein, in the first configuration, the ottoman cushion is disposed at the first predetermined height, and
wherein, in the second configuration, the ottoman cushion is disposed at the second predetermined height.

9. The seating arrangement of claim 8 , wherein the seat further comprises:
a leg rest connected to and moveable in relation to a front end of the seating surface;
a head rest connected to and moveable in relation to the top end of the back rest.

10. The seating arrangement of claim 9 , wherein, in the second configuration, the leg rest, back rest, head rest, and ottoman cushion together form a lower bunk beneath the top bunk.

11. The seating arrangement of claim 10 , wherein the ottoman cushion and the leg rest include abutting, adjacent edges with shapes that complement one another.

12. The seating arrangement of claim 11 , wherein the ottoman cushion includes a bulged section and the leg rest includes an indentation along the abutting, adjacent edges that complement one another.

13. The seating arrangement of claim 8 , wherein the ottoman further comprises:
an ottoman frame supporting the ottoman cushion, the ottoman frame including an ottoman frame scissor element permitting the ottoman cushion to transition between the first predetermined height and the second predetermined height.

14. The seating arrangement of claim 13 , wherein the ottoman frame scissor element comprises:
a first scissor element with a first top end and a first bottom end; and
a second scissor element with a second top end and a second bottom end;
wherein the first scissor element is pivotally connected at a first point between the first top end and the first bottom end to the second scissor element at a second point between the second top end and the second bottom end,
wherein the first top end is pivotally connected beneath a first side end of the ottoman cushion,
wherein the first bottom end is pivotally and slidably connected to a second side end of a structural element disposed beneath the ottoman cushion,
wherein the second top end is pivotally and slidably connected beneath a second side end of the ottoman cushion, and
wherein the second bottom end is pivotally connected to a first side end of the structural element.

15. The seating arrangement of claim 8 , further comprising:
at least two vertical supports extending upwardly adjacent to the seat and to the ottoman, the two vertical supports being pivotally connected to the top bunk to permit the top bunk to pivot between the first and second configurations.

16. The seating arrangement of claim 8 , wherein the seat, the top bunk, and the ottoman are attachable to tracks in a floor supporting the seat, the top bunk, and the ottoman.

17. The seating arrangement of claim 1 , wherein the seat further comprises:
a seat frame supporting the seat, the seat frame including a seat frame scissor element permitting the seating surface to transition between the first predetermined height and the second predetermined height.

18. The seating arrangement of claim 17 , wherein the seat frame scissor element comprises:
a first scissor element with a first top end and a first bottom end; and
a second scissor element with a second top end and a second bottom end;
wherein the first scissor element is pivotally connected at a first point between the first top end and the first bottom end to the second scissor element at a second point between the second top end and the second bottom end,
wherein the first top end is pivotally and slidably connected beneath a forward end of the seat cushion,
wherein the first bottom end is pivotally connected to a rear end of a structural element disposed beneath the seat cushion,
wherein the second top end is pivotally connected beneath a rear end of the seat cushion, and
wherein the second bottom end is pivotally and slidably connected to a forward end of the structural element.

19. The seating arrangement of claim 1 , further comprising:
an upper side cushion disposed adjacent a top edge of the top bunk when in the first configuration,
wherein the upper side cushion forms a portion of the top bunk bed when in the second configuration.

20. The seating arrangement of claim 1 , further comprising:
a lower side cushion disposed adjacent a bottom edge of the top bunk when in the first configuration,
wherein the lower side cushion forms a portion of a bottom bunk bed when in the second configuration.

21. The seating arrangement of claim 1 , wherein the seating arrangement is adapted for an aircraft cabin.

22. The seating arrangement of claim 21 , wherein, when positioned within the aircraft cabin, and when in the first configuration, the top bunk is stowed adjacent to a wall of the aircraft.

23. The seating arrangement of claim 21 , further comprising:
