ABSTRACT:
A chair includes a base frame unit, a leg rest frame, an operating unit, and a linkage device. The base frame unit includes a seat frame with front and rear frame portions. The leg rest frame is connected pivotally to the front frame portion of the seat frame, and is pivotable relative to the seat frame between a folded position, where the leg rest frame is disposed under the seat frame and is generally parallel to the seat frame, and an unfolded position, where the leg rest frame is generally coplanar with the seat frame. The operating unit is mounted rotatably on the base frame unit. The linkage device interconnects the operating unit and the leg rest frame, and is responsive to operation of the operating unit for moving the leg rest frame between the folded and unfolded positions.
