Abstract

A chair (10) having a recline control mechanism (154), a limit control apparatus (270) and a tilt mechanism (50). The recline control mechanism (154) operates to adjust resistance to rotation of a back assembly (12) of the chair and includes an actuator lever (182) having a lock structure (224) attached to a movable spring assembly (152). Moving the spring assembly (152) toward and away from a rotation axis (142) for the back assembly (12) adjusts the resistance. The limit control apparatus (270) selectively limits the extent of rotation of the back assembly (12) from about zero degrees to about 3.5 degrees to about seven degrees by using abutment surfaces (306,308,310). The tilt mechanism (50) provides an independent and stable yet passive tilt capability to a backrest of the back assembly (12) by using a pair of brackets (378,322) , two pairs of links (325,328,330,332) and two pairs of rods (336,338,340,342).
