Abstract

A forward longitudinal bearer of a motor vehicle constructed as closed, hollow bearer with an impact-near energy-absorbing part which is so composed section-wise that three series-connected zones result, of which the center zone is located within the area of aggregate support points and exceeds the two adjoining zones as regards their rigidity by the use of materials of increased strength and/or greater wall thickness.
