Purpose. This procedure evaluates the structural durability of a front or rear seat subsystem by subjecting it to real time load and displacement profiles. These profiles are designed and developed to represent a lifetime usage. This procedure describes the durability test execution.

Foreword.

This procedure is primarily intended for laboratory test engineers and technicians. It does not cover every possible aspect of durability testing and is not to be used as a stand-alone procedure. Successful durability testing inherently requires engineering judgment and the ability to recognize and solve problems which are unexpected and/or complex.

This procedure utilizes a generic profile developed from Road Load Data Acquisition (RLDA or vRLDA), drive file development and correlation evaluation. The time required has been reduced by utilizing the damage cycles of a typical seat system and is provided in the appropriate Subsystem Technical Specification (SSTS) or Component Technical Specification (CTS). However, if a new architecture is developed, a new profile can be developed.

Applicability. This procedure applies to all free standing seats or partially free standing seats for GM passenger cars, Sport Utility Vehicles (SUV) and light and medium duty trucks.
