Comparison Of Human Impact Response In Restraint Systems With And Without A Negative G Strap PDF Download

[Author's abstract, shortened by cataloger] The restraint system is a major element in providing occupant safety in modern day military aircraft's. The United States Air Force (USAF) has conducted numerous dynamic tests in order to provide a better restraint system for its pilots and passengers. Various proposals have been made in recent years and been discarded. One such restraint system was the USAF conventional double shoulder strap and lap strap configuration or also called a 5 point restraint system. Although, it shows from the dynamic tests conducted by the USAF at Air Force Aerospace Medical Research Laboratory (AFAMRL) that the 5 point restraint system provides a secured method of restraining the occupant to the aircraft seat, there are still certain kinds of limitations. One such limitation is "submarining" of the lower torso of the occupant which may cause severe injuries to the occupant. In order to avoid that a Negative G strap or a tie down belt strap is attached as an additional restraint to the S point restraint system. A test program was conducted to assess the influence of a negative G strap on restraint dynamics and human impact response.
