  • Patent number: 4645320
    Abstract: A camera mount for a motor vehicle which always maintains the camera level with respect to the road surface regardless of vehicle rotations due to accelerational or gravitational forces to present a camera view typical of what a human would see looking out of the vehicle and responding to such vehicle rotations in the normal manner. The camera is supported on a pendulum suspended from a gimbal support on the vehicle sprung mass and constrained with spring and damping elements which are matched to the spring and damping elements of the vehicle suspension system to produce equal and opposite rotations of the pendulum for rotations of the vehicle.
