2014-10-16
WIP
J826/3
This document describes the CAD model data of legs and back hardware available from SAE for the HPM-1 three-dimensional H-point machine. The elements of the CAD model include the feet, lower and thighs as well as headroom probe and t-bar. Also included are 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. The actual CAD model files are included with this product and are provided in the following formats: CATIA v4 (without parametrics), CATIA v5 (without parametrics), IGES, and STEP.

H-Point Machine (HPM-II) Specifications and Procedure for H-Point Determination - Auditing Vehicle Seats

2020-06-04
WIP
J4002
This Standard provides the specifications and procedures for using the H-point machine (HPM) to audit vehicle seating positions. The HPM is a physical tool used to establish key reference points and measurements in a vehicle. The H-point design tool (HPD) is a simplified CAD 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. 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) to 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.

J4003_200810
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 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.

H-Point Machine (Hpm-Ii) Specifications and Procedure for H-Point Determination - Auditing Vehicle Seats

2004-02-16
HISTORICAL
J4002_200402
The devices described in this document provide a method for a reliable layout and measurement of occupant seating compartments and/or seats. They are not to be construed as tools that measure or indicate occupant capabilities or comfort. The devices are intended for applications at designated seating positions. They are not intended for use in defining or assessing temporary seating, such as folding jump seats. When using the H-Point Machine (HPM), interactions can occur between adjacent seating positions (i.e., having an HPM installed at the center occupant position can change the results obtained for the outboard occupant position). Therefore, only one machine should be installed in a particular row of seats during each test.

J1052_198705
This SAE Recommended Practice 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.
