Research of front seat design parameters on rear seat passenger safety

To study the influence of front seat parameters on rear seat passenger´s safety when front crash happens, this paper uses MADYMO software to establish a rear seat passenger constraint model, which includes car bodies, safety belts and a 5% dummy for impact simulation. Using this model, the simulation values are close to the results of the vehicle impact test. The influence of design parameters including the front seat headrest and backrest parameters on passenger HIC, T3MS, femur force is analyzed by this model. The relationship between front seat parameters and passenger injury values is obtained, further the measure that reducing passenger injury values is proposed.
