Revision of F3083/F3083M-20a Standard Specification for Emergency Conditions, Occupant Safety and Accommodations

Rationale

The chest injury criteria currently prescribed in F3083 uses the shoulder harness loads as an indirect means of assessing possible occupant injuries. It is noted in AC21.22 that “This approach is conditioned by the understanding that belt loads are also strongly influenced by belt geometry, a factor not represented in the analysis.” The automotive industry uses FMVSS 571.208 for assessing occupant safety in crash tests, where anthropomorphic test device (ATD) thoracic acceleration and chest displacement injury criteria are used. The proposed revision to the standard will allow applicants to use the automotive injury criteria as an alternative to shoulder harness load criteria.
