Abstract
A ratcheting, locking actuator for selectively positioning ergonomic devices is disclosed. The actuator has an overrunning, locking clutch in a housing, a lever, a hanging ratchet and a pulley for anchoring a traction element. The pulley is driven by a gear which is driven by the one of two ratchet pawls in either of two selectable directions. The drive direction is controlled by a lever to which a ratchet post is attached. Engagement and disengagement of the ratchet pawls with the drive gear is controlled by steps on the housing. The actuator is especially useful for controlling traction elements such as bowden cables for ergonomic devices such as lumbar supports.
