In order to quantitatively understand the characteristics of the seating posture of pregnant drivers in actual settings, an anthropometric study was performed. In this study, 20 pregnant women, mean gestational age of 31.4 weeks, and 20 non-pregnant women participated after giving written informed consent. Subjects adjusted the seat to their usual driving posture, and fastened the seatbelt in a passenger vehicle. The longitudinal movement of the slide adjuster and the reclining angle of the seat back were measured, along with anthropometric measurements of the seating posture. The results showed that the mean horizontal clearance between the lower rim of the steering wheel and the abdomen of pregnant women is 146 mm, significantly smaller than that of non-pregnant women (251 mm) due to protrusion of the abdomen. In contrast, there was no significant difference in the longitudinal movement of the slide adjuster and the reclining angle of the seat back between the two groups.
