ABSTRACT:
A foldable child's high chair has a use position wherein an occupant can occupy the chair and a folded position wherein the chair can be folded for storage. The chair includes a seat having a base portion and a back support portion. The back support portion includes a stationary section and a movable section which is movable to position the child. A retaining latch is provided for retaining the movable section in at least two different selected positions relative to the stationary section. A frame is provided for supporting the seat and includes a front leg and a rear leg. A first pivot is provided for pivotally coupling the base portion to the front leg, and a second pivot is provided for pivotally coupling the base portion to the rear leg. A third pivot is provided for pivotally coupling the back support to the rear leg. A rigid link member and a pair of pivots are provided for coupling the back support portion to the base portion. The frame, seat, link member, and pivots are cooperable so that when the chair is moved between its use position and its folded position, the base portion pivots in one direction and the back support portion pivots in an opposite direction.
