Abstract: A retractible leg rest for an aircraft chair which is stowed beneath the seat when not in use. The leg rest is mounted on a platform attached to an articulated frame mounted beneath the chair. The reticulated frame includes two quadrant plates which are pivoted at their centers about a horizontal bar extended beneath the front of the seat. The platform quadrant plates are connected by linkage arms and link members so that when the platform is drawn outward from beneath the chair, the quadrant members are swung upward by the link members and the linkage arms elevate the rear of the platform along an arcuate path which passes clear of the front of the seat of the chair so that the leg rest is brought into leg-support relationship with the seal of the chair. The angle of the leg rest to the seat is adjustable by means of an array of notches with quadrant members.
