Description / Abstract: GMW16708, 2nd Edition, March 2016 - Overall Seat Hardness and Seat Hardness Distribution Test Procedure

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 performance characteristics of motor vehicle seating related to occupant support, penetration, and comfort. It provides a means of comparing and assessing comfort-related performance of complete prototype or competitive benchmark vehicle seat systems.

Applicability. These test procedures apply 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 (see SAE J2896).

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