Abstract

A passenger seat with a recliner sofa system includes a passenger seatback with a seatback frame and a seatback cushion. The seatback cushion is rotatable relative to the seatback frame between a stowed configuration and a deployed configuration. In some examples, in the deployed configuration, the seatback cushion extends through the seatback frame. In various examples, in the deployed configuration, the seatback cushion of a forward passenger seat abuts a seat base of an aft passenger seat. In certain examples, a method of reclining a passenger seat with a recliner sofa system includes rotating a seatback cushion of a seatback of a passenger seat relative to a seatback frame of the seatback of the passenger seat, and positioning the seatback cushion relative to the seatback frame such that a portion of the seatback cushion extends through the seatback frame.

First claim

That which is claimed:

1. A passenger seat comprising a passenger seatback, the passenger seatback comprising a seatback frame and a seatback cushion, wherein the seatback cushion comprises a top end and a bottom end, wherein the seatback cushion is rotatable relative to the seatback frame between a stowed configuration and a deployed configuration, and wherein, in the deployed configuration, the seatback cushion extends through the seatback frame and the bottom end of the seatback cushion is spaced apart from the seatback frame in an aft direction.

2. The passenger seat of claim 1 , wherein the seatback cushion is slidable relative to the seatback frame in the deployed configuration.

3. The passenger seat of claim 1 , wherein the bottom end of the seatback cushion is pivotally engaged with the seatback frame.

4. The passenger seat of claim 1 , wherein the seatback cushion comprises a forward surface, an aft surface, and a foot cover configurable between a stowed configuration and a deployed configuration when the seatback cushion is in the deployed configuration, and wherein, in the deployed configuration of the foot cover, the foot cover defines a foot cavity configured to receive a foot of a passenger.

5. The passenger seat of claim 4 , further comprising a seat base, wherein the seatback cushion is foldable relative to the seat base, and wherein, in the deployed configuration, the forward surface of the seatback cushion faces the seat base.

6. The passenger seat of claim 4 , wherein the foot cover is forward of the seatback frame when the seatback cushion is in the deployed configuration.

7. The passenger seat of claim 1 , wherein the passenger seat is an economy class passenger seat.

8. A passenger seat arrangement comprising:
a forward passenger seat comprising a passenger seatback, the passenger seatback comprising a seatback frame and a seatback cushion, wherein the seatback cushion comprises a top end and a bottom end and is rotatable relative to the seatback frame between a stowed configuration and a deployed configuration, and wherein the seatback cushion is slidable relative to the seatback frame when the seatback cushion is in the deployed position; and
an aft passenger seat comprising a seat base,
wherein, in the deployed configuration, the bottom end of the seatback cushion of the forward passenger seat is spaced apart from the seatback frame of the forward passenger seat and abuts the seat base of the aft passenger seat.

9. The passenger seat arrangement of claim 8 , wherein, in the deployed configuration, the seatback cushion extends through the seatback frame.

10. The passenger seat arrangement of claim 9 , wherein, in the deployed configuration, a portion of the seatback cushion extends forward relative to the seatback frame and a portion of the seatback cushion extends aft relative to the seatback frame.

11. The passenger seat arrangement of claim 8 , wherein the forward passenger seat further comprises a forward seat base, wherein, in the stowed configuration, the bottom end of the seatback cushion is adjacent to the forward seat base, and wherein, in the deployed configuration, the bottom end of the seatback cushion is spaced apart from the forward seat base.

12. The passenger seat arrangement of claim 8 , wherein the seatback cushion comprises a forward surface, an aft surface, and a foot cover configurable between a stowed configuration and a deployed configuration when the seatback cushion is in the deployed configuration, and wherein, in the deployed configuration of the foot cover, the foot cover defines a foot cavity configured to receive a foot of a passenger.

13. A method of reclining a passenger seat comprising:
rotating a seatback cushion of a seatback of a passenger seat relative to a seatback frame of the seatback of the passenger seat, wherein the seatback cushion comprises a top end and a bottom end; and
positioning the seatback cushion relative to the seatback frame such that a portion of the seatback cushion extends through the seatback frame and the bottom end of the seatback cushion is spaced apart from the seatback frame in an aft direction.

14. The method of claim 13 , wherein positioning the seatback cushion comprises sliding the seatback cushion relative to the seatback frame.

15. The method of claim 13 , wherein positioning the seatback cushion comprises abutting the bottom end of the seatback cushion with a seat base of an aft passenger seat.

16. The method of claim 13 , further comprising deploying a foot cover from an aft side of the seatback cushion after positioning the seatback cushion relative to the seatback frame.

17. The method of claim 13 , further comprising locking the position of the seatback cushion relative to the seatback frame with a cushion lock.

18. The method of claim 13 , further comprising stowing the seatback cushion by:
positioning the seatback cushion such that the seatback cushion does not extend through the seatback frame; and
rotating the seatback cushion relative to the seatback frame such that the seatback cushion is in a stowed configuration.
