  • Patent number: 4798399
    Abstract: A combination safety cage, for use with an all terrain vehicle (ATV), and whose superstructure has side and head rails, wheel guards, horizontal rails, top overhead rails, rear horizontal rails and laterally projecting rails of tubular construction and with outward radius curves. A heavy bottom plate provides operational stability for the ATV. A seat belt harnesses the driver to the ATV seat. The combination safety cage prevents the driver from putting his foot on the ground while the ATV is moving. The driver is contained and kept within the safety cage, protected from injury, regardless of what direction the ATV overturns or rolls over, and the driver is further protected if the ATV collides with a fixed object.
