Abstract
A three-position reclining chair capable of being placed with its backrest immediately adjacent to a wall without interference from the wall when the chair is reclined. The chair has a base, a rigidly connected seat and armrest assembly, a backrest movably on the seat and armrest assembly, a footrest, and linkage mechanisms for connecting the several parts of the chair together and allowing the chair to assume any of the three positions. The mechanism includes compound front and area pivot linkages which carry a support link on a base plate, and the support link forms part of and carries a four-bar linkage which includes a seat mounting bracket. The compound linkages enable the support link and seat and armrest assembly to move forward when the chair is reclined to provide room for the backrest to tilt back without interference from the wall.
