The auxiliary rear section may be configured to be in the extended position when the seat pan cushion and the seat back cushion are in the first position. The auxiliary rear section may be configured to be in the retracted position when the seat pan cushion and the seat back cushion are in the second position.

First claim

What is claimed:

1. An aircraft seat, comprising:
a seat pan cushion coupled to a seat base;
a seat back cushion;
a head rest coupled to the seat back cushion; and
an auxiliary rear section positioned behind a rear surface of the head rest, the auxiliary rear section configured to transition between an extended position and a retracted position, the auxiliary rear section being extendable and retractable from a cavity defined within a primary rear section, when the auxiliary rear section is in the retracted position, the auxiliary rear section is stowed within the cavity defined by the primary rear section,
the seat pan cushion and the seat back cushion configured to transition between an upright position and a bed position,
the auxiliary rear section configured to be in the extended position when the seat pan cushion and the seat back cushion are in the upright position,
the auxiliary rear section configured to be in the retracted position when the seat pan cushion and the seat back cushion are in the bed position.

2. The aircraft seat of claim 1 , wherein the auxiliary rear section being configured to transition from the extended position to the retracted position while the seat pan cushion and the seat back cushion transition from the upright position to the bed position.

3. The aircraft seat of claim 2 , wherein the auxiliary rear section being configured to transition from the retracted position to the extended position while the seat pan cushion and the seat back cushion transition from the bed position to the upright position.

4. The aircraft seat of claim 1 , wherein the auxiliary rear section being configured to transition from the extended position to the retracted position before the seat pan cushion and the seat back cushion transition from the upright position to the bed position.

5. The aircraft seat of claim 4 , wherein the auxiliary rear section being configured to transition from the retracted position to the extended position after the seat pan cushion and the seat back cushion transition from the bed position to the upright position.

6. The aircraft seat of claim 1 , wherein the aircraft seat comprises:
the primary rear section, the auxiliary rear section coupled to the primary rear section, a surface of the auxiliary rear section being proximate to a surface of the head rest when the auxiliary rear section is in the extended position.

7. The aircraft seat of claim 6 , wherein a top edge of the auxiliary rear section being at an extended height relative to the head rest when the auxiliary rear section is in the extended position.

8. The aircraft seat of claim 7 , wherein the top edge of the auxiliary rear section being at a retracted height relative to the head rest when the auxiliary rear section is in the retracted position.

9. The aircraft seat of claim 6 , wherein the auxiliary rear section is configured to transition between the extended position and the retracted position via the cavity defined within the primary rear section.

10. The aircraft seat of claim 6 , wherein the auxiliary rear section is configured to transition between the extended position and the retracted position along an exterior surface of the primary rear section.

11. A passenger compartment of an aircraft cabin, comprising:
a privacy shell; and
an aircraft seat positioned within the privacy shell, the aircraft seat comprising:
a seat pan cushion coupled to a seat base;
a head rest coupled to the seat back cushion; and
an auxiliary rear section positioned behind a rear surface of the head rest, the auxiliary rear section configured to transition between an extended position and a retracted position, the auxiliary rear section being extendable and retractable from a cavity defined within a primary rear section, when the auxiliary rear section is in the retracted position, the auxiliary rear section is stowed within the cavity defined by the primary rear section,

the seat pan cushion and the seat back cushion configured to transition between an upright position and a bed position,
the auxiliary rear section configured to be in the extended position when the seat pan cushion and the seat back cushion are in the upright position,
the auxiliary rear section configured to be in the retracted position when the seat pan cushion and the seat back cushion are in the bed position.

12. The passenger compartment of claim 11 , wherein the passenger compartment further comprises:
an ottoman, the ottoman positioned proximate to the aircraft seat within the privacy shell.

13. The passenger compartment of claim 12 , wherein the ottoman and the aircraft seat are configured to form a bed surface when the seat pan cushion and the seat back cushion are in the bed position.
