A three-position leg rest mechanism is disclosed. The mechanism includes a locking link and sector members rotatably supported on the locking link. The sector members are operably coupled to the drive rod for rotation therewith. A locking pin engages the sector members to selectively lock the drive member, and hence the leg rest assembly in one of three positions. The end of the locking link opposite the sector members is coupled to the support shaft of the actuation mechanism.
