ABSTRACT:
A three-way, wall-avoiding, reclining chair having an improved actuation system which minimizes the effort and attention required of the chair occupant to actuate the chair to reclining position from the normal generally upright position of the chair. The improved actuation system is achieved by a novel seat linkage mechanism mounting the seat and backrest to a fixed base such that when the occupant sits in the chair when the chair is in the normal generally upright position with the footrest closed, the seat linkage mechanism is urged by the occupant's weight to extend the footrest while moving the seat and backrest forwardly relative to the base into the TV position. However, a releasable lock mechanism is provided to restrain the seat linkage mechanism from moving to the TV position as aforementiond. A manually operable release is associated with the lock mechanism to allow the chair occupant to release the lock mechanism thereby allowing the chair to move into the aforementioned TV position responsive to the weight of the chair occupant. Once in the TV position, the chair may be moved to a further reclining position by the chair occupant simply applying back pressure to the backrest while opening his body causing the backrest to move relative to the seat, and the seat and backrest to move relative to the base into a more pronounced reclining position. To return to the TV position, the occupant merely has to remove pressure from the backrest or lean forwardly in the chair. To move from the TV position back to the normal, generally upright position, the occupant merely closes the footrest by applying pressure with his feet or legs on the footrest to retract the same to closed position which also actuates the seat linkage mechanism to restore the seat and backrest to the normal position.
