Rationale:The SAE HADD Committee recently developed computer-aided design (CAD) data representing the SAE J826 2-D H-point machine (HPD) template. Prior to this activity, CAD versions of the HPD were created by end users based on scans of the official physical plastic template for SAE 2-D J826. This standard provides traceable documentation for the SAE HPD CAD files that can be used as a design template or can verify the shape/ size compliance of existing templates. This project coincides with the SAE HADD Committee’s creation of CAD surface data for the SAE J826 3-D H-point machine (HPM-1) cushion and back pan outer shells published in J826/1_2011. Previous documentation describing the production SAE J826 HPM was contained in a series of 2-D dimensional layout drawings from 1974, the final assembly fixturing jig, and in other minor build and SAE J826 revisions made over the years. Key changes to the template since the earlier plastic template versions include: • Values for the Thigh Length and Lower Leg segment lengths have been updated to reflect values set for the physical HPM-I in J826_2015. • New segments for the Thigh and Lower Leg were created based on FMVSS 208 (§ 571.208 S10.4.2.1) testing requirements.
