  • Patent number: 5230523
    Abstract: A multi-functional child carrier device including a base having a detachable seat, the backrest portion detachably connectable to the base and slots formed within both the back-rest and the base to allow the unit to serve as a child safety seat or as an infant carrier seat utilizing only the backrest. The device includes elevation supports secured and retractable within the base for supporting the base in an elevated position so that the device may function as a child's chair. Wheels are attachable to the elevation supports so that the device may function as a stroller. Extension members may be attached to the retractable legs for further elevation of the device, thereby allowing the device to function as a high chair. Upon removing the backrest portion, and inserting the appropriate seats on the base, the device may function as either a potty-chair or a walker. In addition, the base is configured in such a manner that if inverted, the unit may function as a rocking chair for a small child.
