Abstract
A shiftable carriage mechanism for an incliner chair includes a right support assembly, a left support assembly, a torque tube connected between the right and left support assemblies and an operating lever, each of the right and left support assemblies including a frame subassembly having a base member mountable on the chair frame, and a mounting rail movably positioned above the base member; a toggle drive subassembly for locking the mounting rail above the base member or, when unlocked, for moving the mounting rail towards the base member; and a footrest-legrest subassembly which will become extended when the mounting rail is moved towards the base member. No main extension spring connected between the mounting rails and the base members is utilized.
