Abstract: An improved combination stroller, car seat and carrier for infants comprising a pair of wheels and a handle mounted on a pair of collapsible tubular members mounted through a pair of spaced-apart openings in the outward extending lip rimming the uppermost portion of the back of the seat and anchored to a single axle secured to the rear underside portion of the seat. When the pair of collapsible tubular members are collapsed for use as a car seat for infants inside the motor vehicle, the handle and pair of collapsible tubular members are disposed in a stowed position against the seat back portion of the car seat. The bottom portion of the combination is adapted for disposition in lockable securement either directly to the seat belt safety system of an motor vehicle, such as a car or automobile, or the like, or via an interlocking tray mounted on a seating surface inside the motor vehicle and secured to the body or frame of the motor vehicle.
