Headrest support assembly for recliner chair

A headrest support assembly for a recliner chair that includes a backrest, a backrest frame behind the backrest, a headrest and a carriage mechanism which is capable of shifting between a retracted condition and an extended condition, said headrest support assembly including mirror image right and left support subassemblies which each include

• a mounting bracket to which said headrest can be attached,
• a first support link pivotally connected at an upper end thereof to said mounting bracket,
• upper and lower swing links connected at first corresponding ends to said backrest frame and at corresponding second ends to said first support link, said upper swing link including an opening therein along a length thereof,
• a second support link pivotally connected at an upper end thereof to the mounting bracket and including a pin which extends through said opening, and
• an actuator link connected at its upper end to one of said upper and lower swing links and connectable at its lower end to said carriage mechanism so as to cause said support subassembly to deploy when said carriage mechanism is shifted from a retracted condition to an extended condition and to retract when said carriage mechanism is shifted from an extended condition to a retracted condition.

In a recliner chair which includes a backrest, a backrest frame behind the backrest which supports the backrest, a carriage mechanism which is capable of shifting between a retracted condition and an extended condition, a headrest and a headrest support assembly, the improvement wherein said headrest support assembly includes mirror image right and left support assemblies which each include

• a mounting bracket to which said headrest can be attached,
• a first support link pivotally connected at an upper end thereof to said mounting bracket,
• upper and lower swing links connected at first corresponding ends to said backrest frame and at corresponding second ends to said first support link, said upper swing link including an opening therein along a length thereof.
• a second support link pivotally connected at an upper end thereof to the mounting bracket and including a pin which extends through said opening, and
• an actuator link connected at its upper end to one of said upper and lower swing links and connectable at its lower end to said carriage mechanism so as to cause said support subassembly to deploy when said carriage mechanism is shifted from a retracted condition to an extended condition and to retract when said carriage mechanism is shifted from an extended condition to a retracted condition.

In a full recline incliner chair which includes a backrest, a backrest frame behind the backrest which supports the backrest, a double-shift carriage mechanism which is capable of shifting between a retracted condition, an intermediate extended (inclined) position and a fully extended (full recline) position, a headrest and a headrest support assembly, the improvement wherein said headrest support assembly includes mirror image right and left support assemblies which each include

• a mounting bracket to which said headrest can be attached,
• a first support link pivotally connected at an upper end thereof to said mounting bracket,
• upper and lower swing links connected at first corresponding ends to said backrest frame and at corresponding second ends to said first support link, said upper swing link including an opening therein along a length thereof,
• a second support link pivotally connected at an upper end thereof to the mounting bracket and including a pin which extends through said opening, and
• an actuator link connected at its upper end to one of said upper and lower swing links and connectable at its lower end to said carriage mechanism so as to cause said support subassembly to deploy when said carriage mechanism is shifted from a retracted condition to an intermediate extended condition and to retract when said carriage mechanism is shifted from an intermediate extended condition to a retracted condition.
