Abstract: A child carrier usable as a backpack and as a stroller. The carrier includes a frame having upper and lower ends in a lengthwise axis extending between the ends. Front wheels are supported by the lower end of the frame, and a child seat and backpack straps are connectable to the frame. Rear wheels are connected to the frame via a rear support assembly that includes sliders movable along the longitudinal axis of the frame, first members pivotally connected to the sliders, and second members pivotally connected to the first members and to the frame. The rear support assembly is movable to a first position in which the rear wheels are adjacent to the frame, for permitting use of the carrier as a backpack, and to a second position in which the rear wheels are positioned away from the frame, for use of the carrier as a stroller.
