Abstract

A passenger seat arrangement is provided for a single-aisle vehicle, such as a narrow-body aircraft. In some examples, the passenger seat includes a passenger seat having a seat plane. The passenger seat is positioned such that the seat plane is at a non-square and non-zero acute angle relative to a plane of the aisle. The passenger seat is a non-lie flat seat movable between an upright position and a neutral position. A seat back of the passenger seat is at a non-zero angle relative to a seat base of the passenger seat in both the upright position and the neutral position.

First claim

That which is claimed:

1. A passenger seat arrangement for a single-aisle aircraft comprising:
a first side-facing passenger seat comprising a first seat base, a first seat back, and a first seat plane;
a first privacy console supporting the first passenger seat a second side-facing passenger seat comprising a second seat base, a second seat back, and a second seat plane;
a second privacy console supporting the second passenger seat; and
an aisle defined between the first passenger seat and the second passenger seat and comprising an aisle plane extending in a forward and aft direction,
wherein the first passenger seat is a non-lie flat passenger seat moveable only between an upright position and a neutral position and wherein the first seat back is at a non-zero angle relative to the first seat base in both the upright position and the neutral position, wherein the first seat back is at an angle from about 90 degrees to about 100 degrees relative to the first seat base in the upright position, wherein the first seat back is at an angle from about 125 degrees to about 135 degrees relative to the first seat base in the neutral position, and wherein, in the neutral position, the first passenger seat is configured to support a passenger such that the passenger's head and knees are elevated above a lower back region of the passenger and such that the knees are elevated compared to the upright position,
wherein the second passenger seat is a non-lie flat passenger seat movable only between an upright position and a neutral position and wherein the second seat back is at a non-zero angle relative to the second seat base in both the upright position and the neutral position, wherein the second seat back is at an angle from about 90 degrees to about 100 degrees relative to the second seat base in the upright position, and wherein the second seat back is at an angle from about 125 degrees to about 135 degrees relative to the second seat base in the neutral position,
wherein the first seat plane is at a non-square and non-zero acute angle relative to the aisle plane and such that the first seat plane is closer to perpendicular than parallel relative to the aisle plane,
wherein the second seat plane is at a non-square and non-zero acute angle relative to the aisle plane and such that the second seat plane is closer to perpendicular than parallel relative to the aisle plane, and
wherein a position of the first privacy console relative to the aisle and a position of the second privacy console relative to the aisle is fixed.

2. The passenger seat arrangement of claim 1 , wherein the first seat plane and the second seat plane are each at the non-square and non-zero acute angle in the aft direction such that a front side of the first seat back is aft-facing and a front side of the second seat back is aft-facing.

3. The passenger seat arrangement of claim 1 , wherein the first seat plane and the second seat plane are each at the non-square and non-zero acute angle in the forward direction such that a front side of the first seat back is forward-facing and a front side of the second seat back is forward-facing.

4. The passenger seat arrangement of claim 1 , wherein one of the first seat plane or the second seat plane is at the non-square and non-zero acute angle in the aft direction such that one of the first seat back or the second seat back is aft-facing, and wherein the other of the first seat plane or the second seat plane is at the non-square and non-zero acute angel in the forward direction such that the other of the first seat back or the second seat back is forward-facing.

5. The passenger seat arrangement of claim 1 , wherein the first seat back and the second seat back are both inboard-facing and face the aisle.

6. The passenger seat arrangement of claim 1 , wherein the first seat back and the second seat back are both outboard-facing and face away from the aisle.

7. The passenger seat arrangement of claim 1 , wherein one of the first seat back or the second seat back is inboard-facing and facing the aisle, and wherein the other of the first seat back or the second seat back is outboard-facing and facing away from the aisle.

8. The passenger seat arrangement of claim 1 , wherein the first passenger seat and the second passenger seat each have direct access to the aisle.

9. The passenger seat arrangement of claim 1 , further comprising:
a third passenger seat aft of the first passenger seat and comprising a third seat base, a third seat back, and a third seat plane, wherein the third passenger seat is a non-lie flat passenger seat moveable between an upright position and a neutral position and wherein the third seat back is at a non-zero angle relative to the third seat base in both the upright position and the neutral position; and
a fourth passenger seat aft of the second passenger seat and comprising a fourth seat base, a fourth seat back, and a fourth seat plane, wherein the fourth passenger seat is a non-lie flat passenger seat moveable between an upright position and a neutral position and wherein the fourth seat back is at a non-zero angle relative to the fourth seat base in both the upright position and the neutral position,
wherein the aisle is defined between the third passenger seat and the fourth passenger seat,
wherein the third seat plane is at a non-square and non-zero acute angle relative to the aisle plane,
wherein the fourth seat plane is at a non-zero and non-zero acute angle relative to the aisle plane, and
wherein the first passenger seat, second passenger seat, third passenger seat, and fourth passenger seat each have direct access to the aisle.

10. The passenger seat arrangement of claim 1 , wherein a width of the aisle when the first passenger seat and the second passenger seat are in the upright positions is the same as a width of the aisle when the first passenger seat and the second passenger seat are in the neutral positions.

11. The passenger seat of claim 1 , wherein the aisle comprises a floor plane, and wherein, in the upright position of the first passenger seat, the first seat base is at an angle of about 7 degrees off the floor plane, and wherein, in the neutral position, the first seat base is at an angle of about 15 degrees off the floor plane.

12. A method of installing a passenger seat arrangement in a single-aisle aircraft comprising:
providing a first side-facing passenger seat comprising a first seat base, a first seat back, and a first seat plane, wherein the first passenger seat is supported by a first privacy console, wherein the first passenger seat is a non-lie flat passenger seat moveable between an upright position and a neutral position and wherein the first seat back is at a non-zero angle relative to the first seat base in both the upright position and the neutral position, wherein the first seat back is at an angle from about 90 degrees to about 100 degrees relative to the first seat base in the upright position, wherein the first seat back is at an angle from about 125 degrees to about 135 degrees relative to the first seat base in the neutral position, and wherein, in the neutral position, the first passenger seat is configured to support a passenger such that the passenger's head and knees are elevated above a lower back region of the passenger and such that the knees are elevated compared to the upright position;
providing a second side-facing passenger seat comprising a second seat base, a second seat back, and a second seat plane, wherein the second passenger seat is supported by a second privacy console, wherein the second passenger seat is a non-lie flat passenger seat movable between an upright position and a neutral posit
