Techniques for Developing Child Dummy Protection Reference Values


An electronic version of the docket submission #74-14 Notice 97 Item 069. This document summarizes the various child anthropomorphic dummies in use around the world, and makes recommendations for child dummy protection reference values for the Hybrid III 12-month old, 3-year-old, and 6-year-old dummies.

Supplement: Development of Injury Criteria for the Assessment of Advanced Automotive Restraint Systems - II
(208 Final Rule Docket: NHTSA-00-7013)



In the SNPRM on advanced air bags, NHTSA proposed a comprehensive set of injury criteria for evaluating the potential for injury to the head, neck, chest and lower extremities for the various dummy sizes, ranging from the 1-year-old child to the 50th percentile male. This supplemental technical paper summarizes the comments received related to injury criteria, provides the agency's responses to the comments, and discusses the various performance limits implemented in the final rule.

Final Rule Nij (Version 10) Reference Implementation (EXE file)



*Self-extracting ZIP file: This code is a reference implementation of the Final Rule Nij (Version 10) injury criteria that was written for purposes of clarity and no consideration has been made for speed. style, or efficiency. The Standard C++ library was used to avoid any confusion due to c-style memory allocation.

Program Input: Three ascii x-y files, where each line of the input file contains two floating point values, one for the time and one for the y value

*** All three files must have the same number of points and the same time data ***
*** All input data must be unfiltered and will be filtered within this program ***

Program Output: The Nij injury criteria, the time of Peak injury.
