摘要：	The Federal Aviation Administration (FAA) has standards and regulations that are intended to protect aircraft occupants in the event of a crash. However, side-facing seats were not specifically addressed when aircraft seat dynamic test standards were developed in the late 1980s. Since then, considerable research has been conducted to increase knowledge about injury risks and mitigation technologies for automotive and aviation applications. Some injury risks such as those to the head, chest, and pelvis are common to both automotive and aviation side-impact scenarios. FAA research has determined that typical side-facing seat configurations could pose additional neck and flailing injury risks. To address these identified risks, the FAA sponsored research to develop neck injury criteria applicable during lateral impacts. This research also evaluated the overall injury risks of the seat configurations identified as having the greatest injury potential. The research included impact tests using postmortem human subjects and the ES-2 test dummy. In this report, the latest advancements in side-facing seat impact testing technology and biomechanical knowledge are used to identify new testing and injury assessment methods intended to ensure fully side-facing aircraft seat designs provide the same level of safety afforded occupants of forward- and aft- facing seats. The methods identified include: use of the ES-2re test dummy and the injury criteria cited in the automotive safety standards to assess injury, adapting test procedures related to test dummy seating, clothing and instrumentation, applying injury criteria originally applicable to forward- facing seats, reducing flailing injuries by limiting occupant excursion and contact, and applying the new neck injury criteria developed by the FAA- sponsored research.
