Abstract: Wearing a child restraint system (CRS) greatly improves the crash-safety of children. However, the number ofFKLOGUHQ¶V LQMXULHV LQ WUDIILF DFFLGHQWV KDVQ¶W GHFUHDVHG 7KHUHIRUH PXFK IXUWKHU LPSURYHPHQW RI &56 LV UHTXHVWHG
Recently, active control of restraint systems for occupants has been studied to improve crash-safety and their effectivenesshas been shown. We proposed active harness control for CRS and showed its effectiveness. We constructed a simulation
model without harness control. It consists of a child dummy model and a CRS model. We attached a mechanism thatchanged the harness length in the CRS model. Additionally, we constructed a control system. In this system, harness force
is feed backed and the controller changes the belt length for keeping harness force constant in car crashes. Simulations
were executed and the injury risks were decreased compared to the model without control of the harness. Thus we clarified
the effectiveness of active control of CRS in numerical simulations.
