With the development of computing technology in recent years, numerical simulation system is developed to calculate the body behavior on a computer. There are some advantages of applying numerical simulation in vehicle development. For example, the cost reduction, safety and easiness of changing parameters. On the contrary, it is difficult to validate the numerical model. Therefore, the experiment to measure the behavior of the human body it is necessary. In this research,s fundamental experiment is performed in order to investigate the body behavior when seated in a vehicle. A fundamental experiment is performed for investigating the influence of the lateral acceleration on human body and the characteristic behavior of the human body is found.
