Title:Motor Vehicle Driver and Passenger Head Position
Issuing Committee:Human Accom And Design Devices Stds Comm
Scope: This SAE Recommended Practice establishes the location of both driver and passenger heads inside a vehicle for the purpose of describing spatial requirements. Driver lateral head position includes head movement looking to the left and right while driving. Ellipitical (head position contour) models in both two and three dimensions are used to represent 95th and 99th percentiles of driver and passenger head locaitons. this document describes two different procedures for locating driver head position contours, depending on whether or not the driver workspace is like that found in a passenger car or a heavy truck. the need for two different procedures has led to a vehicle classificaiton scheme which labels vehicles as either Class A (passenger cars) or Class B (heavy trucks) according to definitions given in SAe J1100 APR97.
