  • Patent number: 4258979
    Abstract: A rear view mirror assembly mounted to one side of a given vehicle is disclosed herein and includes a mirrored surface supported in a fixed position relative to a predetermined observation point for viewing a second trailing vehicle. This mirrored surface includes a first segment horizontally and/or vertically curved in accordance with changing magnification ratios, preferably in a way which defines a substantially linear relationship between the position of the trailing vehicle and the horizontal and/or vertical position of its image on the curved surface segment. In this way, as the trailing vehicle approaches the lead vehicle from behind, horizontal and/or vertical movement of its image across the curved segment is controlled, preferably to a speed linearly proportionate to the speed of the trailing vehicle relative to the lead vehicle. At the same time, the mirrored surface provides a view incorporating the rear section of the lead vehicle including its rear tires on the mirror supported side.
