Links are pivoted, connecting the stationary tracks and the movable tracks with said linkage mechanism, to move the body and its movable tracks, longitudinally forwardly relative to the stationary tracks as the seat links, backrest and leg rest move from upright to T.V. position, and to then move the body and its movable track, further forwardly longitudinally relative to the stationary track, as the seat links, backrest and leg rest move from T.V. position to fully reclined position.

Abstract: Linkage operated recliner chair having a TV position wherein a footrest is projected forwardly by a control handle while the seat and backrest undergoes slight reclining movement relative to a fixed base. However, due to linkage connected between the footrest linkage and the seal linkage, the seat and backrest which is pivotally mounted to the seat, also undergo forward translatory motion during movement of the footrest to extended position. Thus, while the seat and backrest undergo rearward and downward reclining movement, the backrest will not engage an adjacent wall due to the translatory movement. Such action in the trade is known as wall avoiding.Further, and more pronounced, wall avoiding action is achieved by the chair of the present invention when moving to further reclining positions beyond the TV position.
