ABSTRACT:
A three-position leg rest mechanism includes a link and sector members rotatably supported to the link. The sector members are coupled to a drive rod for rotation therewith. A biased pin engages the sector members and releasably locks with the sector members in each of three positions. A locking link end opposite the sector members is coupled to a support shaft of the actuation mechanism. An elastically compressible member is positioned between the sector members which is partially compressed by the pin as the pin moves relative to the sector members, reducing contact noise between the pin and the sector members.
