This study compared obese and non-obese drivers in the preferred seat and steering wheel setting and preferred driving posture. Twenty-one extremely obese and 23 non-obese drivers participated. Each participant determined the most preferred setting of the interior components using an adjustable vehicle mock-up; the preferred components setting and corresponding preferred driving posture were recorded. The participant groups exhibited significant differences in the preferred interior components setting. The obese group created larger steering wheel-seat space than the non-obese, with greater rearward seat displacement, more upright steering wheel angle and smaller steering wheel column displacement. It also exhibited more upright seatback angle deemed necessary for facilitating steering wheel reach with the increased steering wheel-seat distance. The between-group differences in the preferred driving posture were less pronounced: no significant group mean angle differences were found except for the elbow joint angles. Also, the mean hip joint centre positions did not significantly differ. Practitioner Summary: To contribute to larger driver packaging, this study compared obese and non-obese drivers in the preferred vehicle interior components setting and driving posture. The obese group created significantly larger space between the steering wheel and seat than the non-obese, through interior components adjustments. The between-group postural differences were less pronounced.
本研究比较了肥胖和非肥胖驾驶员在首选座椅和方向盘设置以及首选驾驶姿势方面的差异。21名极度肥胖驾驶员和23名非肥胖驾驶员参与了研究。每位参与者使用可调节的车辆模型确定车内部件的最优选设置；记录优选的部件设置和相应的优选驾驶姿势。参与者组在优选的车内部件设置上表现出显著差异。肥胖组比非肥胖组创造了更大的方向盘-座椅空间，座椅向后位移更大，方向盘角度更直立，方向盘柱位移更小。为了在增加方向盘-座椅距离的情况下便于够到方向盘，肥胖组还表现出更直立的座椅靠背角度。在首选驾驶姿势方面，组间差异不太明显：除了肘关节角度外，未发现显著的组平均角度差异。此外，平均髋关节中心位置也没有显著差异。从业者总结：为了给更大的驾驶员座舱空间设计提供参考，本研究比较了肥胖和非肥胖驾驶员在优选的车辆内部部件设置和驾驶姿势方面的差异。通过调整车内部件，肥胖组在方向盘和座椅之间创造的空间明显大于非肥胖组。组间姿势差异不太明显。
