DOBLE-BEAM STRUCTURE FOR SIDE IMPACT OF AUTOMOBILE DOOR

摘要

The present invention relates to a door impact beam of a vehicle, and more particularly, a separate box-shaped reinforcement side filled with a resin foam compressed therein to increase shock absorption and propulsion inside the side impact beam of a vehicle door. By providing an impact beam to double the reinforcement structure for the side impact, it is possible to increase the shock absorption and the propulsion force in the case of an external impact, thereby reducing the injury rate and impact force of the door invading the cabin. It relates to a double beam structure for the side impact of the door of the vehicle.
