Abstract
A carriage mechanism for supporting the frame, seat, backrest, legrest and footrest of a glider/three-way recliner chair includes mirror-image right and left support assemblies connected by a torque tube, each support assembly including a base subassembly which provides front and rear mounting points and a main linkage subassembly which is suspended from these front and rear mounting points, the main linkage subassembly including front and rear scissor links which are pivotally connected, a mounting plate for attachment to a seat frame, a backrest support flange, a rear drive link and a rear ottoman link. Each main linkage subassembly is capable of moving in a forward and rearward gliding motion relative to a flooring surface when the support assembly is in a retracted condition and in a forward and rearward motion which is parallel to the flooring surface when the support assembly is in an intermediate extended condition. Such parallel motion will tend to stop due to gravity, thus obviating the need for a positive locking linkage.
