Abstract
An extendable and retractable leg rest includes a first member which is mounted for rotation to a support. A second member supporting a footrest is coupled to the first member and slides relative to the first member as the first and second members rotate, extending away from the first member as the first and second members are rotated into a raised position and retracting toward the first member as the first and second members are rotated into a lowered position. Movement of the second member relative to the first member is driven by a third member coupled to the second member by a gear system.
