The purpose of this study is to measure eye position of the Japanese driver. Test cars were three Japanese-produced passenger cars. Subjects were 264 males and 53 females.
Eye range contours of various seatback angles were drawn and were compared with SAE J941c's. In side view the eye position for Japanese drivers is somewhat to the rear and lower than that of American drivers. In plan view, the minor axes of eyellipses of Japanese drivers are shorter than those of SAE eyellipse.
