Abstract

An aircraft seat may include a seat back coupled to a shell of one or more passenger compartment shell sections of a passenger compartment installed within an aircraft cabin. The aircraft seat may include a seat pan coupled to a floor of the aircraft cabin proximate to an ottoman installed within the passenger compartment. The seat back may be in contact with a surface of the seat pan when the aircraft seat is in a first position. The seat back may be separated from the surface of the seat pan when the aircraft seat is in a second position. The seat back may be configured to move independently of the seat pan when the aircraft seat transitions between the first position and the second position.

First claim

What is claimed:

1. An aircraft seat, comprising:
a seat back coupled to a shell of one or more passenger compartment shell sections of a passenger compartment installed within an aircraft cabin, the seat back coupled to the shell by a first set of linkages, the linkages having two pivot points, a first pivot point located at the seat back and a second pivot point located at the shell;
the seat back configured to move from a first seat back position to a second seat back position by the set of linkages; and
a seat pan coupled to a floor of the aircraft cabin proximate to an ottoman installed within the passenger compartment, the seat pan configured to move from a first seat pan position to a second seat pan position,
the seat back being in contact with a surface of the seat pan when the seat back is in the first seat back position and the seat pan is in the first seat pan position,
the seat back being separated from the surface of the seat pan when the seat back is in the second seat back position and the seat pan is in the second seat pan position,
the seat back being configured to move independently of the seat pan when the seat back transitions between the first seat back position and the second seat back position.

2. The aircraft seat of claim 1 , the seat pan further comprising:
at least one seat pan cushion configured to align with at least one ottoman cushion of the ottoman when the seat pan is in the second seat pan position.

3. The aircraft seat of claim 2 , the at least one seat pan cushion including a first seat pan cushion and a second seat pan cushion, the first seat pan cushion and the second seat pan cushion being unaligned when the seat pan is in the first seat pan position, the first seat pan cushion and the second seat pan cushion being aligned when the seat pan is in the second seat pan position.

4. The aircraft seat of claim 3 , the second seat pan cushion being set at an angle relative to the first seat pan cushion when the seat pan is in the first seat pan position.

5. The aircraft seat of claim 3 , the second seat pan cushion being stacked on the first seat pan cushion when the seat pan is in the first seat pan position.

6. The aircraft seat of claim 3 , the first seat pan cushion and the second seat pan cushion being aligned with the at least one ottoman cushion when the seat pan is in the second seat pan position.

7. The aircraft seat of claim 6 , the at least one ottoman cushion including a first ottoman cushion and a second ottoman cushion, the first seat pan cushion and the second seat pan cushion being aligned with the first ottoman cushion and the second ottoman cushion when the seat pan is in the second seat pan position, the first ottoman cushion and the second ottoman cushion being unaligned with the first seat pan cushion and the second seat pan cushion when the seat pan is in the first seat pan position.

8. The aircraft seat of claim 7 , the second ottoman cushion being stacked on the first ottoman cushion when the seat pan is in the first seat pan position.

9. The aircraft seat of claim 1 , the seat back and the seat pan being separated by a select distance when the seat pan is in the second seat pan position and the seat back is in the second seat back position.

10. The aircraft seat of claim 1 , the seat pan configured to extend into a space of the passenger compartment, the space bounded in part by the shell of the passenger compartment and a plane defined by a surface of the seat back.

11. The aircraft seat of claim 1 , the first seat pan position including at least one of an upright position or a recline position, the second seat pan position including a lie-flat position.

12. The aircraft seat of claim 11 , the seat pan configured to rotate about an axis through a side of a seat pan base to transition between the upright position and the recline position.

13. The aircraft seat of claim 12 , the seat pan configured to rotate about the axis through the side of the seat pan base to transition between the upright position and the recline position during a translation of the aircraft seat.

14. The aircraft seat of claim 13 , at least one of the seat back or the seat pan being configured to move independently of the ottoman when the seat pan transitions between the first seat pan position and the second seat pan position.

15. The aircraft seat of claim 1 , wherein the set of linkages cause the seat back to actuate upward when transitioning between the first seat back position and the second seat back position.

16. A passenger compartment of an aircraft cabin comprising:
one or more passenger compartment shell sections;
an ottoman;
an aircraft seat, comprising:
a seat back coupled to a shell of the one or more passenger compartment shell sections, the seat back coupled to the shell by a first set of linkages, the linkages having two pivot points, a first pivot point located at the seat back and a second pivot point located at the shell, the seat back configured to move from a first seat back position to a second seat back position by the set of linkages; and
a seat pan coupled to a floor of the aircraft cabin proximate to the ottoman, the seat pan configured to move from a first seat pan position to a second seat pan position,
the seat back being in contact with a surface of the seat pan when the seat back is in the first seat back position and the seat pan is in the first seat pan position,
the seat back being separated from the surface of the seat pan when the seat back is in the second seat back position and the seat pan is in the second seat pan position,
the seat back being configured to move independently of the seat pan when the seat back transitions between the first seat back position and the second seat back position.
