The terms included in the Glossary are general in nature and may not apply to all manufacturers’ systems. All terms in Section 3 apply to automotive inflatable restraint systems in general which are initiated by an electric or mechanical stimulus upon receipt of a signal from a sensor. These terms are intended to reflect existing designs and the Glossary will be updated as information on other types of systems becomes available. Appendix A is included to identify terminology that is no longer in common use or specifically applicable to inflatable restraint systems, but was published in the December 2001 version of SAE J1538.
This glossary is updated to include changes in technology and remove definitions that are no longer commonly used. Sections 3 and 4 were consolidated into one section to ease location of definition, and many references were removed that were deeded unnecessary in support of this document.
