Abstract

A passenger seat row for a vehicle such as a passenger aircraft. The passenger seat row includes at least two passenger seats attached to a common frame. Each of the at least two passenger seats includes a backrest forming a recess on a front of the backrest, a cushion removably disposed in the recess, and a seat pan including a fixed frame and a moving frame movably coupled to the fixed frame. In a taxi, takeoff and landing (TTOL) mode the moving frames are retracted relative to the fixed frames and the cushions are disposed in the recess. In a bed mode the moving frames are extended relative to the fixed frames and the cushions are positioned atop the fixed frames.

First claim

What is claimed is:

1. A passenger seat row, comprising:
a frame; and
at least two passenger seats attached to the frame, each of the at least two passenger seats comprising:
a backrest forming a recess on a front of the backrest;
a cushion removably disposed in the recess; and
a seat pan including a fixed frame and a moving frame movably coupled to the fixed frame;
wherein:
the fixed frame comprises spaced frame members interconnected by spaced beams and a foraminous plate attached atop the spaced beams, at least one of the spaced frame members defining a rack on an inboard side thereof;
the moving frame comprises spaced frame members interconnected by spaced beams and a foraminous plate attached atop the spaced beams, each of the spaced frame members defining an elongate slot; and
a forward beam of the spaced beams of the fixed frame is disposed in the elongate slot of each of the spaced frame members of the moving frame for guiding movement of the moving frame relative to the fixed frame;

wherein in a taxi, takeoff and landing (TTOL) mode of the passenger seat row, the moving frame of each of the at least two passenger seats is retracted relative to the moving frame's respective fixed frame and the cushion is disposed in the recess; and
wherein in a bed mode of the passenger seat row, the moving frame of each of the at least two passenger seats is extended relative to the moving frame's fixed frame and the cushion is positioned atop the moving frame's respective fixed frame.

2. The passenger seat row according to claim 1 , wherein a length dimension of the cushion is substantially equal to an amount of travel of the moving frame relative to the fixed frame.

3. The passenger seat row according to claim 1 , wherein the moving frame translates relative to the fixed frame as the moving frame extends and retracts.

4. The passenger seat row according to claim 1 , further comprising a locking mechanism associated with each of the at least two passenger seats for locking relative motion between the moving frame and the fixed frame.

5. The passenger seat row according to claim 4 , wherein the locking mechanism comprises:
a lock configured to interact with the rack on at least one of the frame members of the fixed frame to lock a position of the moving frame relative to the fixed frame;
a lever positioned on the moving frame; and
a Bowden cable coupled to each of the lock and the lever, wherein in use, pulling the lever causes an inner cable of the Bowden cable to disengage the lock from the rack to permit movement of the moving frame relative to the fixed frame.

6. The passenger seat row according to claim 1 , wherein:
when in the TTOL mode, the moving frame is positioned above the frame; and
when in the bed mode, the moving frame is positioned forward of the frame.

7. The passenger seat row according to claim 1 , wherein the frame comprises:
spaced beam tubes supporting the fixed frame of the at least two passenger seats;
spreaders;
legs; and
at least one armrest.

8. The passenger seat row according to claim 1 , comprising at least three passenger seats.

9. An aircraft passenger seat, comprising:
a frame;
a backrest attached to the frame, the backrest forming a recess on a front of the backrest;
a cushion removably disposed in the recess; and
a seat pan attached to the frame, the seat pan including a fixed frame and a moving frame movably coupled to the fixed frame;
wherein:
the fixed frame comprises spaced frame members interconnected by spaced beams and a foraminous plate attached atop the spaced beams, at least one of the spaced frame members defining a rack on an inboard side thereof;
the moving frame comprises spaced frame members interconnected by spaced beams and a foraminous plate attached atop the spaced beams, each of the spaced frame members defining an elongate slot; and
a forward beam of the spaced beams of the fixed frame is disposed in the elongate slot of each of the spaced frame members of the moving frame for guiding movement of the moving frame relative to the fixed frame;

wherein in a taxi, takeoff and landing (TTOL) mode of the aircraft passenger seat, the moving frame is retracted relative to the fixed frame and the cushion is disposed in the recess; and
wherein in a bed mode of the aircraft passenger seat, the moving frame is extended relative to the fixed frame and the cushion is positioned atop the fixed frame.

10. The aircraft passenger seat according to claim 9 , further comprising a locking mechanism for locking relative motion between the moving frame and the fixed frame, the locking mechanism comprising:
a lock configured to interact with the rack on at least one of the frame members of the fixed frame to lock a position of the moving frame relative to the fixed frame;
a lever positioned on the moving frame; and
a Bowden cable coupled to each of the lock and the lever, wherein in use, pulling the lever causes an inner cable of the Bowden cable to disengage the lock from the rack to permit movement of the moving frame relative to the fixed frame.

11. The aircraft passenger seat according to claim 9 , wherein:
the moving frame translates relative to the fixed frame;
when in the TTOL mode, the moving frame is positioned above the frame; and
when in the bed mode, the moving frame is positioned forward of the frame.
