SAE J4002_200508

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 using the H-point machine (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. They are not intended for use in defining or assessing temporary seating, such as folding jump seats. With this revision, the 2004 version of SAE J4002 has been subdivided into three separate standards in order to specify in more detail the uses of the HPM II and HPD in auditing vehicles (J4002:2005), benchmarking vehicles (J4003), and in designing vehicle interior packages (J4004).
