Description / Abstract: Introduction

Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. This document provides test methods for evaluating the design H-Point (i.e., Hip Point, also referred to as Seating Reference Point (SgRP)) and Torso Angle measurement. Specifically this standard focuses on setting the seat in design position for the H-Point measurements.

Applicability. This procedure is to be used on all General Motors seats. This test procedure applies to complete seat systems (production seats or prototypes built at the intended manufacturing quality). Testing must be performed on complete seat backs and complete seat cushions. Tests performed on subsystems or individual components will not be considered valid. 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.

Remarks. The tools and procedures for determining seat coordinate positions used in this document are based on the SAE J826 H-Point Manikin.
