A collapsible child carrier assembly having a support frame which comprises a pair of hinge members, each of which includes a bore extending therein. The support frame further includes front and back support structures, each of which are attached to the hinge members. Also included in the support frame is a top support bar having opposed ends and a pair of elongate slots extending longitudinally therein adjacent respective ones of the opposed ends thereof. The top support bar is pivotally connected to the hinge members via a pair of pivot pins which extend through and are movable within respective ones of the slots. The top support bar is movable between a locked position whereat the opposed ends thereof are inserted into respective ones of the bores so as to maintain the top support bar in fixed relation to the front support structure, and an unlocked position whereat the opposed ends thereof are removed from within the bores so as to allow the top support bar to be pivotally movable relative to the front support structure about the pivot pins. The movement of the top support bar between the locked and unlocked positions is facilitated by the movement of the pivot pins within respective ones of the slots.
