Seating apparatus

1. An aircraft seat comprising:

a seat chassis;

a seat assembly comprising a seat pan and a seat back;

the seat pan being mounted to the seat chassis by a first pivoting connection defining a seat pan pivot axis about which the seat pan pivots, the location of the seat pan pivot axis being fixed relative to the seat chassis, the first pivoting connection being configured such that the seat pan can pivot about the seat pan pivot axis without undergoing a related translational movement;

the seat back being mounted to the seat pan by a second pivoting connection, the second pivoting connection defining a seat back pivot axis about which the seat back pivots, the seat pan pivot axis being located in front of the seat back pivot axis; and

at least one seat pan link for controlling pivoting of the seat pan about said seat pan pivot axis; wherein the at least one seat pan link is coupled to the seat pan in front of the seat pan pivot axis;

at least one recline link connected to the seat back and the at least one seat pan link; and

wherein the seat pan pivot axis is located between the seat back pivot axis and a mid- point of the seat pan.

2. The aircraft seat as claimed in claim 1 , wherein the seat pan pivot axis is located coincident with or proximal to a centre of gravity of the seat assembly in a longitudinal direction.

3. The aircraft seat as claimed in claim 1 , wherein the seat chassis comprises:

at least one seat pan track; and

at least one seat pan follower adapted to travel in said at least one seat pan track, the at least one seat pan follower being connected to the at least one seat pan link.

4. The aircraft seat as claimed in claim 3 , wherein the at least one seat pan follower is disposed at a pivotal connection between said at least one recline link and the at least one seat pan link.

5. The aircraft seat as claimed in claim 3 , wherein the seat pan comprises first and second seat pan sidemembers, the seat pan sidemembers being mounted to the seat chassis by the first pivoting connection, wherein the seat back is mounted to the first and second seat pan sidemembers by the second pivoting connection.

6. The aircraft seat as claimed in claim 1 , wherein the at least one recline link comprises a seat back decoupling mechanism operable selectively to decouple the at least one recline link from the seat back.

7. The aircraft seat as claimed in claim 1 , wherein the seat back pivot axis is a real pivot axis and the second pivoting connection is configured such that the seat back pivot axis undergoes translation relative to the seat pan as the seat back pivots about said seat back pivot axis.

8. The aircraft seat as claimed in claim 7 , wherein the second pivoting connection comprises a seat pan hinge link and a seat back hinge link, the seat pan hinge link and the seat back hinge link being pivotally connected to each other, the seat back pivot axis being defined by the pivoting connection of said seat pan hinge link and the seat back hinge link.

9. The aircraft seat as claimed in claim 8 , wherein the seat pan hinge link comprises a first arm pivotally connected to the seat pan and a second arm movably coupled to the seat back; and the seat back hinge link comprises a first arm pivotally connected to the seat back and a second arm movably coupled to the seat pan.

10. The aircraft seat as claimed in claim 1 , comprising a seat base for mounting fixedly to a floor of an aircraft.

11. The aircraft seat as claimed in claim 10 , wherein the seat chassis is movably mounted to said seat base.

12. The aircraft seat as claimed in claim 10 , wherein said seat base comprises at least one longitudinal guide to provide longitudinal movement of the seat chassis relative to the seat base.

13. The aircraft seat as claimed in claim 1 , comprising a leg rest, wherein the leg rest is mounted to said seat pan by a third pivoting connection, the third pivoting connection defining a leg rest pivot axis about which the leg rest pivots.

14. The aircraft seat as claimed in claim 13 , comprising at least one leg rest link coupled to the leg rest.

15. The aircraft seat as claimed in claim 14 , further comprising:

at least one leg rest track; and

at least one leg rest follower adapted to travel in said at least one leg rest track, the at least one leg rest follower being connected to said at least one leg rest link.

16. The aircraft seat as claimed in claim 14 , wherein the at least one leg rest link is connected to the at least one seat pan link.

17. An aircraft comprising one or more aircraft seats as claimed in claim 1 .

18. An aircraft seat comprising:

a seat chassis;

a seat assembly comprising a seat pan and a seat back;

the seat pan being mounted to the seat chassis by a first pivoting connection defining a seat pan pivot axis about which the seat pan pivots, the location of the seat pan pivot axis being fixed relative to the seat chassis, the first pivoting connection being configured such that the seat pan can pivot about the seat pan pivot axis without undergoing a related translational movement;

the seat back being mounted to the seat pan by a second pivoting connection, the second pivoting connection defining a seat back pivot axis about which the seat back pivots, the seat pan pivot axis being located in front of the seat back pivot axis;

at least one seat pan link for controlling pivoting of the seat pan about said seat pan pivot axis; wherein the at least one seat pan link is coupled to the seat pan in front of the seat pan pivot axis;

at least one recline link connected to the seat back and the at least one seat pan link; and

wherein the seat pan pivot axis is located in a central region of the seat pan.
