The leg rest of the chair is extensible from a position against the front of the seat to a position forwardly thereof. A pair of spaced scissor links support the leg rest in retracted and extended positions when actuated by a movable member such as a chair back, handle or the like. The leg rest is supported on the scissor links for forward movement thereon when extended to position the leg rest a greater distance from the front of the chair. The forward movement of the leg rest tensions springs and operate latches which retain the leg rest in a selected one of a plurality of forward positions. The latches are automatically released upon the operation of the scissor links to retract the leg rest to its position adjacent to the front of the chair which permits the springs to return the leg rest to its initial position before the end of the retractive movement of the links. |
