Abstract
A door beam of a motor vehicle is provided in a vehicle door. Section modulus of the door beam is progressively decreased from a center section toward opposite ends of the door beam and the contour of cross-section of the door beam is of a continuously formed round wave shape, whereby the door beam absorbs an impact of a collision by virtue of imparting the force of the impact to both bending and tensile forces so that the bending moment acting on the center of the door beam decreases.
