ABSTRACT:
An impact beam structure for automobile side doors is disclosed. In the impact beam structure, a protector panel is mounted to the impact beam by a plurality of guide rods, which are welded to the protector panel and pass through the guide holes of the impact beam prior to being tightened by nuts. The guide rods individually have both a stopper at the welded junction and an uneven part at a section between the impact beam and the stopper. The uneven part normally spaces the protector panel apart from the impact beam and is selectively thrust into the guide hole in the event of a side collision, thus allowing the protector panel to primarily absorb impact energy. The stopper selectively comes into contact with the impact beam, thus stopping the impact energy absorbing operation of the protector panel and allowing the impact beam to secondarily absorb the impact energy.
