SAE J826_201511

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). This document has been revised to include only metric length units to describe critical HPM-I dimensions to eliminate rounding differences that occur when switching between measurement systems. In addition, several references to body shape references and template dimensions were corrected or removed from section 5. All other content regarding the application of the HPM-I has been reaffirmed to comply with the SAE 5-year review policy.
