Abstract

The objective of this study is to verify the effects of a motorized seat belt on dummy kinematics and responses in pre-crash sled system with pre-impact braking. For this purpose, the sled test with pre-impact braking was conducted by using Hybrid III with a modified lumbar. It was confirmed that the motorized seat belt decreases the chest movement not only during the pre-impact braking phase but also in the collision phase compared to the case of a current seat belt. Moreover, the motorized seat belt could reduce chest acceleration due to the improvement of initial restraint effect.
