  • Patent number: 4349964
    Abstract: A viewing angle measuring device for automotive vehicles. The measuring device includes an elliptical template representing a so-called visual ellipse. The template is arranged in the vehicle in a prescribed position with respect to a driver's seat regarding a center position and an axial inclination. A measuring beam projector may be guided with its optical axis and/or with a measuring beam tangentially along a governing curve of the elliptical template. A goniometer, continuously indicating the viewing angle, is connected to the measuring beam projector to determine the beam direction with respect to a reference plane as a measure of the viewing angle.
