ABSTRACT:
A folding chair having a locking device for locking the chair in the open position so that it is safe for children. The chair has a frame including a seat, a back rest, and legs. The seat includes two parallel seat frame members. the back rest includes two parallel back rest members. The seat frame members are hingeably attached to the back rest members for selectively entering an open position wherein the seat frame members are substantially perpendicular to the back rest members, and a folded or closed position wherein the seat frame members extend substantially parallel to the back rest members. Each seat frame member has a seat frame member rear portion defined as the part of the seat frame member rearward of the back rest member. As the chair is folded the back rest member sweeps rearward, diminishing the size of the seat frame member rear portion. A locking device is pivotally attached at the seat frame member rear portion for selectively locking the chair by abutting the back rest member and preventing the back rest member from sweeping rearward, and thereby preventing the chair from folding.
