A motor and sprocket drive move a child safety seat between a sitting and reclining position on a base secured by a vehicle safety belt. A drive shaft and gear system, drive belt with pulley system, double action winch and cord system or other drive system positioned within an enclosed base move the sprocket reversibly. A remote control operable by the driver of the vehicle controls the seat motor. A pair of sprockets housed in the base interacts horizontally with a mating pair of arched tracking grooves in the seat to move the seat with no weight bearing on the sprockets. The electric motor may be battery powered or plugged into the cigarette lighter of the vehicle. The sprocket or a solenoid lock the seat in place.
