Abstract

The automotive headrest is intended to provide comfort, safety, convenience and durability to a vehicle's passengers and driver. In this study, impact and fatigue analyses were carried out for three headrest shape models-A, B and C. These models have the same material properties and the same force was applied to them. Impact and fatigue analyses demonstrated that all of the models obtained almost the exact same result values. This study found that all models had similar equivalent stress, deformation, fatigue life and main damage parts due to the fact that the shared same material properties. Better safety and fatigue life can be anticipated by changing the material of the headrest in order to secure more stable safety. An automotive headrest optimized for safety and durability is thought to have been developed through the impact and fatigue analyses of this study.
