ABSTRACT:
A handle actuated leg rest assembly for a recliner chair's movable leg rest. A novel control linkage of the leg rest functions to lock up the leg rest when the leg rest is fully extended or when the leg rest is fully retracted, so that the leg rest does not `drift` out of either the extended or retracted attitudes after being placed therein. The control and leg rest linkages are locked up in the leg rest extended attitude by positioning certain of the control linkage's links in an over center position relative to the pivot points of those links, and are locked up in the retracted attitude by positioning certain other of the control linkage's links in an over center position relative to the pivot points of those other links.
