Abstract

One of the most critical problems in the protection of aircraft occupants in a crash environment is posed by vertical acceleration levels which may exceed those that the human body can withstand without injury in a direction parallel to the vertebral column. Because sufficient crush space does not exist within the floor structure for adequate energy absorption, the seat must play a significant role in attenuating these potentially injurious forces to tolerable levels. Several recently designed aircraft have been equipped with seats that incorporate systems for the absorption of energy in vertical directions. There are however still several areas of uncertainty in the design criteria that require additional research. The measurements with cadavers and anthropometric dummies are presented. The design of such seats is also important in the application of biomechanical safety seats in cars and buses. (TRRL)
