Neck Injury Analyzer Tool Based on Mechanical Impedance Characteristics for the Design of Human-seat Systems

The importance of developing a driving seat effective for reducing neck injuries has been increased to produce a safer automobile against car accidents in recent years. However, there does not exist an efficient methodology to develop such an innovative driving seat with consideration of dynamic characteristics of a human body as well as the interactions between a driver and a seat. The present paper proposes a new simulation method based on the mechanical impedance properties of a human-seat system that can provide quantitative analysis of neck injuries. Effectiveness of the proposed method is shown through a set of computer simulations by changing dynamic properties of a seat model
