SAE J2732-2020 PDF

Scope: This document provides dimension definitions that facilitate geometric quantification and evaluation of seats. Dimensions described in this document have been designed to be measured in a CAD environment; however@ many dimensions require the HPM position and attitude. This can be obtained by physically establishing H-point using benchmark or auditing procedures OR by measuring the HPD within a CAD or modelling system. Refer to the appropriate document for these procedures. These dimensions are package independent in that they do not require use of the HPM-II supplemental thigh/leg/shoe. Three types of seat geometry reference points and measurements have been developed: ? Simple reference points and measurements not related to H-point. ? H-point dependent reference points and measurements that utilize the seat characterization capabilities of the HPM to quantify seat measurements. ? Cross sectional seat trim outlines. For convenience and simplicity@ many terms associated with H-point devices use human body parts in their name. However@ they should not be construed as measures that indicate interaction with any or all occupants concerning accommodation@ human capabilities@ or comfort. H-point devices do not represent the size or posture of any category of occupant.
