Patent ID: 7540520

Claim:
An extendable and retractable leg rest comprising: a support member; a first elongated member rotatably coupled to the support member; a second elongated member coupled to the first member for telescopic movement relative to the first member, the second elongated member including a first rack gear and a footrest; an actuator coupled to the support member and to the first member to rotate the first and second members relative to the support member; a third elongated member rotatably coupled to the support member and including a second rack gear; a gear component comprising at least one spur gear and supported by the first elongated member and operatively engaging the first and second rack gears; a biasing member coupling the third elongated member to the first member to allow relative linear motion between the first and third members, and biasing the third elongated member into operative engagement with the gear component, wherein as the actuator rotates the first, second, and third members, movement of the third member relative to the first member causes the second member to translate relative to the first member.
