  • 2777 Accesses

Part of the Lecture Notes in Mechanical Engineering book series (LNME)


Currently, in the automotive industry great emphasis is put on reducing of the energy consumption of applied materials, weight reducing and performance optimizing. The reason is an environmental protection, sustainable development, reducing of fuel consumption and increasing of vehicle safety. One of the ways how to quickly find a suitable solution is the application of TRIZ method (theory of inventive problem solving). On existing solution is showed, how this method can help with an improvement of car headrest safety. With its help two solutions were designed and implemented. Their verification is done using FEM model. From the results of established models data for calculating the head injury criteria (HIC) factor have been obtained. From these data is clear that the proposed solutions improve the safety of headrest.
