Abstract

ECE R80 describes two alternative test procedures to validate occupant safety of bus seats. Static loads are applied or the seats have to fulfill dynamic crash testing being loaded with 50%ile HIII crash dummys. Under load the seat rows may not move relative to the floor and must absorb the impact energy within the seat structure. Analysis of bus accidents and sled tests lead to the question, if both alternatives ensure adequate levels of protection. Does passing the static test will safely inhibit movement of the seats under crash condition? Does passing the regulation result in seats providing good protection for all sizes of occupants?
