ABSTRACT:
A convertible stroller and car seat including a housing positioned below a seat portion for receiving a pair of front wheels and a pair of rear wheels in retracted condition. An operating handle extends outwardly through the rear wall of the housing and is connected to a rotatable actuator disk from which connecting rods extend to respective wheel assemblies supporting the wheels. Movement of the handle from side to side causes the actuating disk to rotate, thereby either extending the wheels from the wheel housing or retracting the wheels into the wheel housing. One pair of diagonally opposed wheel carriers is adapted to pivot directly into and out of the wheel housing, and the remaining pair of diagonally opposed wheel carriers pivots into and out of the wheel housing and also rotate by 90.degree. so that the four wheels when fully extended each lie in parallel planes for ease of use of the stroller. The stroller also includes a retractable handle that is in an extended position when used as a stroller and that is in a retracted position when the device is used as a car seat. The wheel housing includes a lower wall that has openings to receive the wheels, and serves to prevent contact of any of the wheel structure with vehicle upholstery when the device is used as a car seat.
