SEAT ARTICULATION MECHANISM
First Claim
Patent Images
1. A seat articulation mechanism, comprising:
- first and second seat pan members each having first and second opposed ends and including a seat pan roller positioned about the second end of the first and second seat pan members;
first and second seat pan articulation linkages each defining an articulation control pathway along which the seat pan rollers travel as the seat articulation mechanism translates between an upright and a sleeping configuration through a lounge configuration;
first and second main translation linkages pivotally connected to the first and second seat pan members, the first and second seat pan articulation linkages, and first and second stationary frame members, respectively;
first and second secondary translation linkages pivotally connected to the first and second seat pan articulation linkages and the first and second stationary frame members; and
an actuator for driving the motion of at least one of the first and second main and secondary translation linkages to drive the mechanism between the upright and sleeping configurations through the lounge configuration.

Abstract
A seat articulation mechanism including a seat pan member that travels along a pathway defined in a seat articulation linkage as the entire mechanism translates between an upright and sleeping configuration through a lounge configuration. The mechanism further includes main and secondary translation linkages, one of which is driven by a single actuator to drive the mechanism between the upright and sleeping configurations.

8. A seat articulation mechanism, comprising:
-
a seat pan member having first and second opposed ends and having a seat pan roller for facilitating movement attached about the second end; a seat pan articulation linkage defining an articulation control pathway along which the seat pan roller travels as the seat articulation mechanism translates between an upright and a sleeping configuration through a lounge configuration; a main translation linkage pivotally connected to the seat pan member, the seat pan articulation linkage, and a stationary frame member; a secondary translation linkage pivotally connected to the seat pan articulation linkage and the stationary frame member; and an actuator for driving the motion of at least one of the main and the secondary translation linkages to drive the mechanism between the upright and sleeping configurations through the lounge configuration. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A passenger seat, comprising:
-
a seat articulation mechanism comprising; first and second seat pan members cooperatively supporting a seat bottom with each including a seat pan roller positioned about one end of the first and second seat pan members; first and second seat pan articulation linkages each defining an articulation control pathway along which the seat pan rollers travel as the mechanism translates between an upright and a sleeping configuration through a lounge configuration; first and second main translation linkages pivotally connected to the first and second seat pan members, the first and second seat pan articulation linkages, and first and second stationary frame members, respectively; first and second secondary translation linkages pivotally connected to the first and second seat pan articulation linkages and the first and second stationary frame members; and an actuator for driving the motion of at least one of the first and second main and secondary translation linkages to drive the mechanism between the upright and sleeping configurations through the lounge configuration; a seat back pivotally connected to the first and second seat pan members configured to pivot between an upright position and a generally horizontal sleeping position; and a leg rest configured to move between an upright position and a generally horizontal sleeping position. - View Dependent Claims (16, 17, 18, 19)
