Abstract

A longitudinal bearer constructed as hollow profile of a motor vehicle frame, which is equipped with introduction places for introducing chassis forces into the frame and into the longitudinal bearer and with a longitudinal deformable bearer section arranged outside of the introduction places and dissipating impact energy; the longitudinal bearer section which by reason of different wall thicknesses has a resistance to buckling that increases in the direction toward the vehicle center, is transversely subdivided over its length at least into two bearer pieces connected with each other by circumferential seams; the wall thickness of a respective bearer piece becomes greater and/or the wall quality thereof becomes better in the direction toward the vehicle center from bearer piece to bearer piece than the wall thickness and/or the wall quality of the bearer piece disposed in front thereof.
