Abstract
A linear actuator control system (10) as applied to a chaise lounge (12) having a seat back (14) pivotally hinged to a seat portion (16). The actuator (20) includes a piston assembly (46) mounted within a cylinder assembly (48) for controlled movement through a position control assembly (50). A rotatable valve assembly (172) mounted within the piston (66) prevents the flow of hydraulic fluid through a passageway (88) in the piston to selectively lock the piston (66) in position within the cylinder (96). A cam assembly (174) translates linear movement of a cable (244) into rotational movement by the interaction of a cam follower (216) and a cam member (214) having an opening (224) formed therein that interacts with the cam follower (216).
