Abstract (en)

A reversible adjustable lumbar support and headrest tilt mechanism (10) is provided for installation on a chair. A side bracket (86) is coupled to each side of the back frame (12; 100), and a back bracket (16; 74) is pivotably coupled to each side bracket. An actuator (40; 40A; 64; 110) is pivotably coupled to the back frame (12; 100) that has an extendable and retractable shaft (38; 68). In a first orientation, with the actuator shaft (38; 68) extending toward the upper end of the back frame (12; 100), a headrest back insert (30; 78) is couple-able to and between the back brackets (16; 74), such that extension and retraction of the actuator shaft (38; 68) rotates the headrest back insert (30; 78). In a second orientation, with the actuator shaft (38; 68) extending toward the lower end of the back frame (12; 100), a lumbar push bar (200) is couple-able to and between the back brackets (16; 74), such that extension and retraction of the actuator shaft (38; 68) rotates the lumbar push bar (200).
