Book Description
An airbag generates a considerable amount of kinetic energy during its inflation process. As a result substantial forces can be developed between the deploying airbag and the out-of-position occupant. Accident data and laboratory test results have indicated a potential for head, neck, chest, abdominal, and leg injuries from these forces. This suggests that mitigating such forces should be considered in the design of airbag restraint systems. This document outlines a comprehensive set of test guidelines that can be used for investigating the interactions that occur between the deploying airbag and the occupant who is near the module at the time of deployment. Static and dynamic tests to investigate driver and passenger systems are given. Static tests may be used to sort designs on a comparative basis. Designs that make it through the static sorting procedure may be subjected to the appropriate dynamic tests. On a specific vehicle model, engineering judgment based upon prior experience in airbag testing may make it unnecessary to conduct the tests identified by the document or may indicate that different tests should be conducted. Mild severity and moderate severity crash pulses are described in Section 5. These pulses are not vehicle-specific, but represent a general acceleration-time history that approximates what occurs with a large variety of vehicles. The mild severity crash pulse is near the threshold of many airbag deployments and represents a high-frequency accident event. Since small children are more likely than adults to be out of position due to preimpact braking, this pulse can be used for the child tests. Since preimpact braking has much less of an effect on adults, the moderate severity crash pulse can be used for adult testing. The described pulses or other vehicle specific pulses may be used. No performance limits are specified in this document. References 2.1.4 2 and 16 gives interpretations of dummy responses relative to human injury.

The members of the SAE Human Biomechanics and Simulations Standards Steering Committee have reviewed J1980 and made a conscientious decision to stabilize this Information Report. J1980, first issued in 1990, documents the tests developed by the U.S. auto industry to assess the risk of injury to occupants in close proximity to driver or passenger frontal airbags. It served as a basis for ISO/TR10982 as auto manufacturers in Europe and Asia began to introduce frontal airbags in their regions. In 2000, NHTSA added out-of-position tests and limits to FMVSS 208. J1980 is a historic document and contains a more comprehensive set of out-of-position test conditions than either ISO/TR10982 or FMVSS 208.

Book Description
The fourth edition of the Handbook of Human Factors and Ergonomics has been completely revised and updated. This includes all existing third edition chapters plus new chapters written to cover new areas. These include the following subjects: Managing low-back disorder risk in the workplace Online interactivity Neuroergonomics Office ergonomics Social networking HF&E in motor vehicle transportation User requirements Human factors and ergonomics in aviation Human factors in ambient intelligent environments As with the earlier editions, the main purpose of this handbook is to serve the needs of the human factors and ergonomics researchers, practitioners, and graduate students. Each chapter has a strong theory and scientific base, but is heavily focused on real world applications. As such, a significant number of case studies, examples, figures, and tables are included to aid in the understanding and application of the material covered.

Book Description
This book provides a state-of-the-art look at the applied biomechanics of accidental injury and prevention. The editors, Drs. Narayan Yoganandan, Alan M. Nahum and John W. Melvin are recognized international leaders and researchers in injury biomechanics, prevention and trauma medicine. They have assembled renowned researchers as authors for 29 chapters to cover individual aspects of human injury assessment and prevention. This third edition is thoroughly revised and expanded with new chapters in different fields. Topics covered address automotive, aviation, military and other environments. Field data collection; injury coding/scaling; injury epidemiology; mechanisms of injury; human tolerance to injury; simulations using experimental, complex computational models (finite element modeling) and statistical processes; anthropomorphic test device design, development and validation for crashworthiness applications in topics cited above; and current regulations are covered. Risk functions and injury criteria for various body regions are included. Adult and pediatric populations are addressed. The exhaustive list of references in many areas along with the latest developments is valuable to all those involved or intend to pursue this important topic on human injury biomechanics and prevention. The expanded edition will interest a variety of scholars and professionals including physicians, biomedical researchers in many disciplines, basic scientists, attorneys and jurists involved in accidental injury cases and governmental bodies. It is hoped that this book will foster multidisciplinary collaborations by medical and engineering researchers and academicians and practicing physicians for injury assessment and prevention and stimulate more applied research, education and training in the field of accidental-injury causation and prevention.
