Chair with recline control mechanism, recline limit control and back tilt mechanism

摘要

A chair having a recline control mechanism, a limit control apparatus and a tilt mechanism. The recline control mechanism operates to adjust resistance to rotation of a back assembly of the chair and includes an actuator lever having a lock structure attached to a movable spring assembly. Moving the spring assembly toward and away from a rotation axis for the back assembly adjusts the resistance. The limit control apparatus selectively limits the extent of rotation of the back assembly from about zero degrees to about 3.5 degrees to about seven degrees by using abutment surfaces. The tilt mechanism provides an independent and stable yet passive tilt capability to a backrest of the back assembly by using a pair of brackets, two pairs of links and two pairs of rods.
