Abstract:

Problems dealing with impact injury caused by linear acceleration are covered. Papers cover spinal column injuries caused by gz eyeballs down impact, tensile eyeballs up loading of the spinal column, and lower leg injuries, as sustained by front seat occupants in automobile glance off impacts at high speed. Head and neck injury mechanisms are discussed both from a physiological and neurological standpoint. Both helmeted and unhelmeted head impacts are analyzed, and helmet test and evaluation methods are covered. Several papers described accidentinjury investigation methods, including a helicopter crash test with instrumented dummies aboard. Injury-preventing hardware is covered papers include restraint harness slack, dynamic preload of the restrained body, testing and evaluation of new shock-absorbing stroking helicopter seats, automotive air bag testing, and the use of a webbing tear shock absorber on a helicopter crew chiefs restraint harness. The validation of a spinal injury model and a more general kinematics whole body model are also discussed. Finally, the cost effectiveness of torso armor was discussed in two papers. The conclusions from this meeting will hopefully be applied for improved impact protection.
