Claim:
A reclining chair comprising: a base frame; a pivot link having a lower pivot end connected pivotally to said base frame, and an upper pivot end; a back frame having a lower end; a carriage having front and rear ends; a linkage mechanism for coupling pivotally said lower end of said back frame to said rear end of said carriage and said upper pivot end of said pivot link, thereby permitting movement of said back frame from an upright position to a tilted position relative to said carriage in response to pressure applied on said back frame and thereby permitting movement of said carriage between front and rear carriage positions relative to said base frame; a leg rest assembly connected pivotally to said front end of said carriage and said base frame and driven by said carriage to move from a retracted position to an extended position during movement of said carriage from the front carriage position to the rear carriage position; and stop means provided on said linkage mechanism and said rear end of said carriage for positioning said back frame at the tilted position; wherein, when said back frame is at the tilted position, movement of said carriage from the front carriage position to the rear carriage position due to an external applied force results in movement of said leg rest assembly from the retracted position to the extended position and simultaneously results in rearward pivoting movement of said back frame, said linkage mechanism, said carriage and said pivot link relative to said base frame; wherein said linkage mechanism includes: a first link member mounted on said lower end of said back frame and having a first pivot end connected pivotally to said rear end of said carriage, and a second pivot end disposed rearwardly and below said first pivot end; a second link member having a rear pivot end connected pivotally to said second pivot end of said first link member, and a front pivot end; and a third link member having a front end connected pivotally to said carriage, a rear end connected pivotally to said front pivot end of said second link member, and an intermediate portion connected pivotally to said upper pivot end of said pivot link.
