Seatbelts are one of the most important passive safety systems in a vehicle for securing occupants during a traffic accident. As highly automated vehicles with numerous seating arrangements are developed in the future, integrated seatbelts will replace traditional seatbelts. Accordingly, the objective of the study is to discuss the safety of integrated seatbelts in comparison with traditional seatbelts, as well as the kinematics of occupants and injury risk in future mixed traffic scenarios. Six finite element simulations were done using an integrated seatbelt and a traditional seatbelt to determine how the configuration of the seatbelt influences occupant kinematics and injury risk. A 50th percentile male human body occupant model (THUMS Version 6.1 AM50) was used to calculate the Brain Injury Criterion (BrIC) and the Head injury criteria (HIC) of the head, the chest deflection, the rib strain, and the vertebrae neck force. Varied mixed pulses, including full-frontal, straight crossing path, and left turn across path were simulated. Based on the results, the difference between the two types of seatbelts is not significant in terms of the prediction of an occupant's injury, but there is a slight change in the occupant's kinematics. Integrated seatbelts have shown promise in reducing injury risks in future mixed traffic scenarios. [ABSTRACT FROM AUTHOR] |
