Abstract: An example baby carrier includes an enclosure, a seat configured to receive a baby, a back frame, and a first support frame. The first support frame includes an extendable arm having a handle, a first hinged leg, and a first wheel mounted to the first leg. The baby carrier is configured to reversibly transition between at least a stowed mode, a stroller mode, and a carrier mode.

Abstract: An improved baby carrier is disclosed that includes a support frame coupled to a seating assembly though a suspension mechanism to provide weight support for a baby or toddler. The baby carrier includes an attachment harness worn by an adult to provide non-slip coupling between the baby carrier and the adult. The baby carrier also includes a semi-rigid coupling between the seat and harness assembly, a seat height adjustment capability, a sturdy support frame configuration, and a braking system. The baby carrier is a structurally stable device, and during use, significantly reduces the load of carrying the baby or toddler on the adult. Further, the baby carrier can have a compact size in a “stowed mode” for mobility, and can be used to meet a variety of user needs and carrying scenarios.
