The MADYMO simulation model of the rear occupant restraint system based a current car model was constructed, researching the influence of the rear seat cushion stiffness and cushion angle with the floor, the 3-point seatbelt webbing stiffness and retractor locking feature on rear-seat passenger safety in the head-on collision. Thereafter, the entire rear occupant restraint system was optimised. The result shows when the rear seat cushion stiffness is 30N/mm, the cushion angle is 25°, the safety belt stiffness is 11% and the webbing output after the retractor locks is 30mm, rear occupant would obtain the optimum protection.
