  • Patent number: 4077663
    Abstract: This chair comprises a chair body having arm rests and being fixed to tracks mounted for longitudinal movement on stationary tracks supported on a floor. Seat links, a leg rest and linkage mechanism connecting said seat links and leg rest to the body and to each other, permit the seat links, and leg rest to be moved from upright position to T.V. position, and then to fully reclined position, and back to T.V. position and upright position. 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.
