| Outline of Final Research Achievements |
In this study, in order to reveal the effect of driving posture on the risk of neck injury during rear impact, investigations on the individual variations in driving postures as well as muscle activities was carried out, and an injury analysis method using active human model was newly developed. Changes in the head posture of vehicle occupants could be determined from the analysis of video images recorded using drive recorder system. Moreover, musculoskeletal model could be utilized in investigating the whole body muscle activities during postural changes. In addition, according to the result of finite element analysis, it was confirmed that changes in head posture may have an influence on the risk of neck injury during rear impact.
