Benchmarking is used to discover the design intent measurements for seating compartments in vehicles when these measurements are either unknown or are specified using differing measurement procedures. This document provides the specifications and procedures to establish consistent measurements for benchmarking vehicle seating positions using the H-Point Machine (HPM-II1) described in SAE J4002 and the H-Point Design tool (HPD) described in SAE J4004. The HPM-II is a physical tool used to establish key reference points and measurements in a vehicle (Figure 1). The HPD is a CAD tool that aids in the benchmarking process (see Appendix A and SAE J4004).
This SAE Recommended Practice defines a set of measurements and standard procedures for motor vehicle dimensions. The dimensions are primarily intended to measure the design intent of a vehicle within a design environment (i.e., CAD). All dimensions in this practice can be measured this way. In addition, some dimensions can be taken in an actual vehicle. If measurements are taken on physical properties, some differences in values should be expected. Also, care should be taken to not confuse design intent measurements with those taken on a physical property. It is intended that the dimensions and procedures described in this practice be generic in their application to both the HPM, described in SAE J826, and the HPM-II, described in SAE J4002. In some circumstances, the figures may only reflect one or the other.

Also, care should be taken to not confuse design intent measurements with those taken on a physical property. Unless otherwise specified, all dimensions are measured normal to the three-dimensional reference system (see SAE J182), except ground-related dimensions, which are defined normal to ground. All dimensions are taken with the vehicle at curb weight unless otherwise specified. All dimensions are measured on the base vehicle and do not include Regular Production Options (RPO) or accessory parts, unless otherwise specified.

This document describes the CAD model data available from SAE for the HPM-1 three-dimensional H-point machine. The elements of the CAD model include the outer surfaces of the cushion and back pans, datum points and lines, and calibration references. The intended purpose for this information is to provide a CAD reference for design and benchmarking as well as a calibration reference for the physical HPM-1 audits. The content and format of the data files that are available are also described.
