H-Point Machine (HPM-II) - Procedure for H-Point Determination - Benchmarking Vehicle Seats
|Publication Date:||1 April 2019|
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).
1 In this document the terms H-point machine, HPM, and HPM-II are used interchangeably to refer to the new H-point machine that is described in SAE J4002. The older H-point machine described in SAE J826 uses the term H-point machine.
