Abstract

An adjustable aircraft passenger seat including a seat bottom, a legrest adjustable in angle relative to the seat bottom, a seatback adjustable in angle relative to the seat bottom, the seatback segmented into a lower seatback and an upper seatback, the lower seatback adjustable in angle relative to the seat bottom and the upper seatback adjustable in angle relative to the lower seatback, and a headrest adjustable in height relative to the upper seatback.

First claim

What is claimed is:

1. An adjustable aircraft passenger seat, comprising:
a seat bottom;
a legrest adjustable in angle relative to the seat bottom;
a seatback adjustable in angle relative to the seat bottom, the seatback segmented into a lower seatback and an upper seatback, the lower seatback adjustable in angle relative to the seat bottom and the upper seatback adjustable in angle relative to the lower seatback;
a headrest separate from the seatback; and
a first actuator dedicated for lower seatback movement and a second actuator dedicated for upper seatback movement;
wherein the upper seatback is pivotably attached at one end to the lower seatback, and the second actuator is horizontally-oriented on a backside of the upper seatback to drive a rotating gear meshed with an arcuate toothed guide of the lower seatback to move the gear along a length of the arcuate toothed guide to adjust an angle of the upper seatback relative to the lower seatback; and
wherein the adjustable passenger seat is adjustable to achieve an upright sitting position for taxi, take-off and landing, and an in-bed lounge sitting position in which the legrest and seat bottom are coplanar, the lower seatback is at an angle to the seat bottom, and the upper seatback is at an angle to the lower seatback.

2. The passenger seat of claim 1 , wherein the lower seatback is pivotably attached at one end to the seat bottom, and the first actuator is vertically-oriented on a backside of the lower seatback to drive pivoting movement of the lower seatback relative to the seat bottom.

3. The passenger seat of claim 1 , wherein the headrest comprises a center portion and side portions adjustable relative to the center portion.

4. The passenger seat of claim 1 , further comprising left and right armrests positioned on opposite sides of the seat bottom.

5. The passenger seat of claim 1 , further comprising a third a actuator dedicated for headrest movement of the headrest.

6. The passenger seat of claim 5 , wherein the third actuator is vertically-oriented on a backside of the upper seatback and connected to the headrest to drive the headrest toward and apart from the upper seatback.

7. The passenger seat of claim 5 , wherein the headrest is arranged to slide along vertically-oriented rails on a backside of the upper seatback to slide the headrest toward and apart from the upper seatback.

8. An aircraft passenger suite, comprising:
a plurality of privacy walls defining boundaries of the passenger suite; and
a passenger seat positioned within the passenger suite, the passenger seat comprising:
a seat bottom,
a legrest adjustable in angle relative to the seat bottom,
a seatback adjustable in angle relative to the seat bottom, the seatback segmented into a lower seatback and an upper seatback, the lower seatback adjustable in angle relative to the seat bottom and the upper seatback adjustable in angle relative to the lower seatback,
a headrest separate from the seatback, and
a first actuator dedicated for lower seatback movement, a second actuator dedicated for upper seatback movement, and a third actuator dedicated for legrest movement,
wherein the upper seatback is pivotably attached at one end to the lower seatback, and the second actuator is horizontally-oriented on a backside of the upper seatback to drive a rotating gear meshed with an arcuate toothed guide of the lower seatback to move the gear along a length of the arcuate toothed guide to adjust an angle of the upper seatback relative to the lower seatback; and

wherein the passenger seat is adjustable to achieve an upright sitting position for taxi, take-off and landing, and an in-bed lounge sitting position in which the legrest and seat bottom are coplanar, the lower seatback is at an angle to the seat bottom, and the upper seatback is at an angle to the lower seatback.

9. The passenger suite of claim 8 , further comprising an ottoman positioned directly forward of the passenger seat, wherein the ottoman is spaced apart from the passenger seat such that a front of the ottoman aligns with an end of the legrest when the legrest is fully deployed.

10. The passenger suite of claim 9 , further comprising a video monitor positioned vertically above the ottoman and directly forward of the passenger seat.

11. The passenger suite of claim 8 , wherein the lower seatback is pivotably attached at one end to the seat bottom, and the first actuator is vertically-oriented on a backside of the lower seatback to drive pivoting movement of the lower seatback relative to the seat bottom.

12. The passenger suite of claim 8 , wherein the headrest comprises a center portion and side portions adjustable relative to the center portion.

13. The passenger suite of claim 8 , wherein the passenger seat further comprises left and right armrests positioned on opposite sides of the seat bottom.

14. The passenger seat of claim 8 , further comprising a fourth actuator dedicated for headrest movement of the headrest.

15. The passenger suite of claim 14 , wherein the fourth actuator is vertically-oriented on a backside of the upper seatback and connected to the headrest to drive the headrest toward and apart from the upper seatback.

16. The passenger suite of claim 14 , wherein the headrest is arranged to slide along vertically-oriented rails on a backside of the upper seatback to slide the headrest toward and apart from the upper seatback.
