Chinese Drivers' Preferred Posture for Sedans' Seat Ergonomic Design

摘要

This study collected data concerning preferred driving postures for sedans of Chinese driving population, aiming for investigating the relationships between drivers' joint angles and their gender, region and anthropometry, and also finding observed optimum driving postures for Chinese drivers. Nine joint angles were measured in preferred postures to more completely describe driving postures, as were the perceptual response, with 1861 subjects. A subset of preferred joint angle range was identified through a filtering mechanism that ensured desired levels of perceptual response. It is found that gender and region both have a significant effect on all angles except torso angle. Stature, weight and sitting acromion height all have effects on different joint angles. The recommended range of 9 joint angles of preferred driving postures is obtained, and the analysis on differences between this study and the previous studies, and on reasons for those differences was conducted.
