ABSTRACT:
A reclining seat of the type characterized by having a seat back which reclines and a seat bottom which elevates, the improvement which comprises linkage means interconnecting the seat back and the seat bottom and providing a ratio of seat back movement to seat bottom movement of greater than 1 to 1. The pivot axis between the seat back and seat bottom resides on a lateral axis extending from one side of the seat to the opposite side of the seat through the anatomical hip joint region of a seat occupant, for permitting the seat back and seat bottom to move relative to each other about the same pivot axis as the seat occupant will move his or her legs relative to the torso.
