Abstract
Driver eyellipses for three “reduced deflection” bucket seats and one conventional bucket seat were developed photogrammetrically. Three driver groups drove four similar cars, each with a different driver's seat. The three groups represented standing height distributions for 1962, 1972 and estimated 1990 U.S. adult populations. In general, the four seats produced similar eyellipses in the front and side view. The eyellipses for the taller population groups were, in general, shifted upward and rearward for each seat. Side view eyellipses for the 1962 and 1990 population samples were statistically different in the fore-aft plane, but not different in the vertical.
