Abstract
Disclosed is a tilt control mechanism for a knee tilt chair that permits the chair to be locked in a number of intermediate tilt positions, as well as in a full upright and a fully reclined position. A portion of a pivotal chair seat support member is a curved flange that is provided with a plurality of spaced openings. The chair control housing contains a lock block slidably supported on guides. An actuator shaft attached to the chair control housing has a cam member attached to the shaft. A quarter turn of the actuator shaft causes the cam member to move the lock block to a forward position adjacent the curved flange. With the lock block in the forward position, one of a plurality of spring loaded pins in the lock block, is allowed to enter one of the openings in the curved flange thereby locking the chair support member of the chair into a predetermined tilt position. Reversal of the actuator shaft allows the lock block to move rearwardly and disengages the spring loaded pin from the opening in the curved flange and allows the tilt position of the chair to be changed by the user.
