  • Patent number: 6739660
    Abstract: A motor and reversible 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, double action winch and cord system, hydraulic drive, screw drive, or other drive system positioned within an enclosed base move the safety seat reversibly. A remote control operable by the driver of the vehicle controls the seat motor. An interconnecting system between the safety seat and the base maintains the safety seat in proximity with the vehicle seat back. The electric motor may be battery powered or plugged into the cigarette lighter of the vehicle.

  • Patent number: 6739661
    Abstract: A child safety seat pivots between a sitting and reclining position on a base secured by a vehicle safety belt. A pair of pivot arms extending from each side of the safety seat slide in a pair of grooves in each side of the base. The primary pivot arm moves in an essentially horizontal groove to maintain a low center of gravity. A secondary pivot arm stabilizes the safety seat and helps to maintain the safety seat back in close proximity with the vehicle seat back. A high pivot arm near the top of each side of the seat may be positioned in a mating opening or a slotted opening in each side of the base. A motor and reversible drive assembly, which may be remotely controlled can be used to move the safety seat.

  • Patent number: 6739659
    Abstract: 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.
