Abstract: A convertible carrier for infants and small children is adjustable to alternative stroller and car seat configurations. The rear wheels of the carrier are mounted on levers which pivot relative to a frame supporting a contoured shell of the carrier. A telescoping handle, mounted pivotally to the levers at points spaced apart from the rear wheels, can be pushed or pulled to pivot the levers, to position the rear wheels in respective operative and storage (car seat) positions. The forward wheels of the carrier can be rotatably mounted directly to the frame. Alternatively, the front wheels can be mounted to the frame through forward levers which pivot on the frame, and are associated with the rearward levers through linking rods, whereby pivoting of the rearward levers causes a corresponding pivoting of the forward levers between operative and storage positions.
