The devices of this SAE Standard provide the means by which passenger compartment dimensions can be obtained using a deflected seat rather than a free seat contour as a reference for defining seating space. All definitions and dimensions used in conjunction with this document are described in SAE J1100. These devices are intended only to apply to the driver side or center occupant seating spaces and are not to be construed as instruments which measure or indicate occupant capabilities or comfort. This document covers only one H-point machine installed on a seat during each test. Certified H-point templates and machines can be purchased from:
SAE International
400 Commonwealth Drive
Warrendale, PA 15096-0001
Specific procedures are included in Appendix A for seat measurements in short- and long-coupled vehicles and in Appendix B for measurement of the driver seat cushion angle. Specifications and a calibration inspection procedure for the H-point machine are given in Appendix C. Additional considerations are necessary when a head restraint measuring device (HRMD) is mounted to an H-point machine (Appendix D).
Rationale
This document has been revised to include:
A new appendix describing the location and purpose for optional measurement divots located on the HPM head room probe, T-bar, and shoes.
An improved definition of the muslin cloth used during the physical installation.
Corrections to the HPM calibration sections regarding the lower leg weight tolerances and the combined HPM-HRMD.
All other content has been reaffirmed to comply with the SAE Five-Year Review policy.
The Human Accommodation and Design Devices Standards Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to tools, models and procedures to create and improve the occupant package ergonomic layout of the vehicle's interior tools and procedures for consistent measurement of vehicle dimensions and seat dimensions taken during design, benchmarking, and auditing. The committee actively leads and works to have its standards adopted internationally. Participants in the SAE Human Accommodation and Design Devices Standards Committee include OEMs, suppliers, academicians, consulting firms, government, and other interested parties.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
