Anthropometrical limitations in the construction of passenger vehicles: Case study

Abstract

The result of anthrometrical limitations is, among other things, the usual construction of passenger automobiles for a range from a 5th-percentile woman to a 95th-percentile man driver, determining the position and adjustability (movement) of the seat, the position and angle of the windscreen, and the torso of the driver. Anthropometrical changes, especially the form of the stochastic normal function for the division of certain measures in Serbia and possibly at the global level, influence the increase in all anthropometrical values but also influence the difference between the measurements for the 5th-percentile woman and the 95th-percentile man driver, for which range the passenger automobile is usually adjusted. On the other hand, this leads to difficulties and the impossibility of normal use of the steering wheel with the hands of a small 5th-percentile aged woman because they are too near, and also the 95th-percentile aged man driver, because they are too far. Therefore, the usual design of the steering wheel for a total 50th-percentile hermaphrodite (man—woman) is no longer sustainable, but the tip of the steering-wheel shaft should also be adjusted to suit a certain range, until a more acceptable technical solution is found.
