This SAE Recommended Practice describes how to position and posture the H-point design tool (HPD) described in Appendix B, and how to establish the seating reference point (SgRP), design H-point travel path, and other key reference points that are used in the design and specification of both driver and passenger seat positions. This practice also provides a method for determining the length of the seat track for a driver seat that adjusts fore/aft. The seat track length is based on a desired level of driver accommodation, assuming a U.S. population containing an equal number of male and female drivers. The procedure can be used to establish driver seat track accommodation for new vehicle designs or to evaluate accommodation in existing vehicles. A general method for determining driver seat track length for any driver population (male and female stature distribution) at any selected accommodation percentile and gender mix is given in Appendix A.

This Standard provides the specifications and procedures for using the H-point machine (HPM1) to audit vehicle seating positions. The HPM is a physical tool used to establish key reference points and measurements in a vehicle (see Figure 1 and Appendix A). The H-point design tool (HPD) is a simplified CAD2 version of the HPM, which can be used in conjunction with the HPM to take the optional measurements specified in this document, or used independently during product design (see Appendix D). These H-point devices provide a method for reliable layout and measurement of occupant seating compartments and/or seats. This document specifies the procedures for installing the H-point machine (HPM) and using the HPM to audit (verify) key reference points and measurements in a vehicle. The devices are intended for application at designated seating positions. They are not to be construed as tools that measure or indicate occupant capabilities or comfort.

This SAE Standard describes head position contours and procedures for locating the contours in a vehicle. Head position contours are useful in establishing accommodation requirements for head space and are required for several measures defined in SAE J1100. Separate contours are defined depending on occupant seat location and the desired percentage (95 and 99) of occupant accommodation. This document is primarily focused on application to Class A vehicles (see SAE J1100), which include most personal-use vehicles (passenger cars, sport utility vehicles, pick-up trucks). A procedure for use in Class B vehicles can be found in Appendix B.

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. Elliptical (head position contour) models in both two and three dimensions are used to represent 95th and 99th percentiles of driver and passenger head locations. 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 classification scheme which labels vehicles as either Class A (passenger cars) or Class B (heavy trucks) according to definitions given in SAE J1100 APR97.

This SAE Recommended Practice describes two dimensional side and rear view 95th and 99th percentile driver and passenger seated head position contours for fixed and horizontally adjustable seats. New information obtained from the SAE Truck Driver Anthropometric and Workspace Study has resulted in development of new head location procedures for trucks and other vehicles with high H-point heights and large steering wheel diameters. Therefore, this practice has been separated into two parts. Part I describes the head location procedure for vehicles with H-point heights (H30) and steering wheel diameters (W9) less than 405 mm and 450 mm, respectively (Class A Vehicles). This class of vehicles includes passenger cars, vans and light trucks. Part II describes a separate head locating procedure for vehicles with H-point heights (H30) between 405 and 530 mm and steering wheel diameters (W9) between 450 and 560 mm (Class B Vehicles).
