Abstract

Describes are passenger seats including a seat pan assembly with a reclining mechanism, a seat back pivotally coupled to the aft end of the seat pan assembly, and a lumbar mechanism coupled to the seat back and/or the seat pan assembly. As examples, the seat pan assembly includes at least one track having a reclining path and a sleeper path, and a sleeper selection control configured to pull a diverter into a position substantially blocking the opening to the reclining path and to push the diverter into a position substantially blocking the opening to the sleeper path. In certain cases, the seat pan assembly also includes a tilting mechanism with a fixed component and a variable component adjustably engaged with each other.

Claims (42)

1. A passenger seat comprising:

(a) a seat pan assembly comprising:

(i) a reclining mechanism;

(ii) a seat frame comprising at least one track comprising a reclining path and a sleeper path;

(iii) a diverter pivotally coupled to the at least one track adjacent an opening to the reclining path and an opening to the sleeper path;

(iv) a sleeper selection control coupled to the diverter and configured to pull the diverter into a position substantially blocking the opening to the reclining path and to push the diverter into a position substantially blocking the opening to the sleeper path; and

(v) at least one pivot bar coupled to an aft end of the seat pan assembly;

(b) a seat back pivotally coupled to the aft end of the seat pan assembly; and

(c) a lumbar mechanism coupled to the seat back and the seat pan assembly;

(d) wherein the at least one pivot bar is positioned within the at least one track so that a circumferential surface of the at least one pivot bar maintains contact with a side of the at least one track when the at least one pivot bar is positioned in the reclining path and when the at least one pivot bar is positioned in the sleeper path.

2. The passenger seat of claim 1 , wherein the sleeper selection control is a button, a knob, a side lever, a lever, a slide, or a latch.

3. The passenger seat of claim 1 , wherein the reclining mechanism is configured to:

(a) adjust a forward position of the seat pan assembly when the diverter is positioned to substantially block the opening to the sleeper path;

(b) adjust the forward position of the seat pan assembly, a rotated position of the aft end of the seat pan assembly, and rotate the lumbar mechanism relative to the seat back when the diverter is positioned to substantially block the opening to the reclining path; and

(c) rotate the seat back between upright and reclining positions.

4. The passenger seat of claim 1 , wherein the reclining mechanism is a gas spring.

5. The passenger seat of claim 1 , further comprising a lever comprising at least two legs, wherein a first leg of the at least two legs is coupled to the diverter via a linkage, and a second leg of the at least two legs is coupled to a first end of a cable, wherein a second end of the cable is coupled to the sleeper selection control.

6. The passenger seat of claim 5 , wherein the cable comprises a telescoping configuration.

7. A seat pan assembly comprising:

(a) a reclining mechanism;

(b) a seat frame comprising at least one track comprising a reclining path and a sleeper path;

(c) a diverter pivotally coupled to the at least one track adjacent an opening to the reclining path and an opening to the sleeper path;

(d) a sleeper selection control coupled to the diverter and configured to pull the diverter into a position substantially blocking the opening to the reclining path and to push the diverter into a position substantially blocking the opening to the sleeper path; and

(e) at least one pivot bar coupled to an aft end of the seat pan assembly, wherein the at least one pivot bar is positioned within the at least one track so that a circumferential surface of the at least one pivot bar maintains contact with a side of the at least one track when the at least one pivot bar is positioned in the reclining path and when the at least one pivot bar is positioned in the sleeper path.

8. The seat pan assembly of claim 7 , wherein the sleeper selection control is a button, a knob, a side lever, a lever, a slide, or a latch.

9. The seat pan assembly of claim 7 , wherein the reclining mechanism is configured to:

(a) adjust a forward position of the seat pan assembly when the diverter is positioned to substantially block the opening to the sleeper path; and

(b) adjust the forward position of the seat pan assembly and a rotated position of the aft end of the seat pan assembly.

10. The seat pan assembly of claim 7 , wherein the reclining mechanism is a gas spring.

11. The seat pan assembly of claim 7 , further comprising a lever comprising at least two legs, wherein a first leg of the at least two legs is coupled to the diverter via a linkage, and a second leg of the at least two legs is coupled to a first end of a cable, wherein a second end of the cable is coupled to the sleeper selection control.

12. The seat pan assembly of claim 1 , wherein the cable comprises a telescoping configuration.

13. A seat pan assembly comprising:

(a) a reclining mechanism;

(b) a seat frame comprising at least one track comprising a reclining path and a sleeper path;

(c) a diverter pivotally coupled to the at least one track adjacent an opening to the reclining path and an opening to the sleeper path;

(d) a push/pull-type cable arrangement is coupled to the diverter; and

(e) at least one pivot bar coupled to an aft end of the seat pan assembly, wherein the at least one pivot bar is positioned within the at least one track so that a circumferential surface of the at least one pivot bar maintains contact with a side of the at least one track when the at least one pivot bar is positioned in the reclining path and when the at least one pivot bar is positioned in the sleeper path.

14. The seat pan assembly of claim 13 , wherein the reclining mechanism is configured to:

(a) adjust a forward position of the seat pan assembly when the diverter is positioned to substantially block the opening to the sleeper path; and

(b) adjust the forward position of the seat pan assembly and a rotated position of the aft end of the seat pan assembly.

15. The seat pan assembly of claim 13 , wherein the reclining mechanism is a gas spring.

16. The seat pan assembly of claim 13 , wherein the push/pull-type cable arrangement comprises a telescoping configuration.
