  • Patent number: 4216992
    Abstract: A close-to-the-wall recliner chair has a body support, i.e., seat and backrest, which is pivotally mounted on a body support frame, and the body support frame is in turn carried on a stationary chair base by roller and track means, thereby permitting forward/rearward motion of the body support frame on the chair base as the body support moves between upright and reclining positions. This forward and rearward motion is effected by a unitized recliner chair mechanism which comprises (a) a conventional recliner mechanism interconnecting the body support frame and the body support, (b) a conventional track and roller assembly, (c) a novel bracket fixedly interconnecting the rollers of the track assembly to the recliner mechanism, and (d) a novel control linkage connected at one end to the track of the roller track assembly and at the opposite end of the footrest linkage of the recliner mechanism.
