Abstract
A double-shift carriage mechanism for supporting the seat, backrest, footrest and legrest of a full recline incliner chair includes mirror image right and left support assemblies connected by a torque tube, each support assembly including an incline frame subassembly, an extendable footrest-legrest subassembly, a toggle drive subassembly, and a recline frame subassembly, the incline frame subassembly shifting from a retracted to an extended condition to convert the chair from an upright to an inclined state and the recline frame subassembly then shifting from a retracted to an extended condition, thus moving the incline frame subassembly along a substantially straight line and converting the chair from an inclined to fully reclined state.
