列車事故時における転換シート着座乗客の下肢傷害評価

抄録

It is important to enhance the safety to passenger even in a train accident. In order to grasp secondary impact risk to walkover seat occupant, the sled tests that assumed a level crossing accident were carried out. The results of the test made it clear that the severity of the leg injury to the passenger was higher than any other parts of body since the passenger's legs collided with the edge of a seating face of the front seat. To reduce such type of injury risk, the seating face which supported both ends of the aluminum pipe with the urethane elastomer was developed based on the impact test results. The sled tests were carried out to identify the injury risk reduction effect of the seating face with buffer. It was found that the leg injury risk of the seating face with buffer reduced for the conventional seating face more than 60%.
