Abstract

PURPOSE: To enhance absorption of impact energy for higher safety by specifying the ratio of the height of thread to the thickness and the ratio of the width of the step to the thickness in the guard bar mounted between the outer panel and the inner panel of the door.
CONSTITUTION: The beam 1 and the patch 3 of the door guard bar G are constructed of a high tensile steel plate and two threads 2 with a U-shaped cross section is formed on the beam a long the length. A step 4 is formed at the position corresponding to the thread 2 projecting to the beam side in such a manner as to be fitted into the thread 2 and the bracket 7 is mounted to both ends of the beam 1. The ratio of the height of the thread to the thickness is fixed at more than 0.040 while the ratio of the width of the step to the thickness at more than 0.027. The height of the step is made three times as large as the thickness. With such an arrangement, buckling of the wall surface can be prevented against impact and the adoption of the high tensile steel plate reduces thickness thereby assuring strength and absorption of impact energy.
