In this paper,the driver head protection scheme of cheap car with common three-point safety belt is studied,which is not equipped with airbag.Through MADYMO simulation calculation and a method combined withDOE test design, cheap car driver head protection is optimal designed by way of adjusting textile fabric elongation and modulating safety belt pretension level.On the base of obtaining desired safety belt optimized parameter, the experimental verification result on physical slip ta-ble shows that the optimization scheme effectively drop degree injury to cheap car driver head, it has met with the lawful regu-lation.The optimization scheme of the project is feasible, and could provide effective reference for occupant restraint system of other similar model cars.
