A study on the design of a 6-point child seat system to enhance safety

Child seats had been widely used as one of CRS(child restraint system). In this study, dynamic simulation of a child seat was carried out with the LS-DYNA software to develop an advanced child seat. The sled test with an existing child seat was carried out first, and then the computer simulations with LS-DYNA software were compared to the sled test to validate the dummy model and computer simulation. After matching the sled test and computer simulation, then a new type of child seat was developed with the computer simulation and optimization. The comparison between the simulation and the sled test showed a good agreement, and the simulation results were proved useful for further development of an advanced CRS.
