VEHICLE SEAT WITH SIMULTANEOUS ARTICULATION OF SEAT PAN AND SEAT BACK

摘要

A vehicle seat that includes a linkage assembly interconnecting a seat pan assembly, seat back assembly and leg rest assembly whereby, as the seat carriage assembly is moved aft the seat pan assembly and the seat back assembly simultaneously adjust to maintain a predetermined seating position during an initial recline motion with the leg rest assembly remaining in a retracted position below the seat pan assembly. The leg rest assembly progressively elevates into a leg-supporting position during a subsequent recline motion as the back rest assembly and seat pan assembly progressively recline towards a lie-flat configuration.
