ABSTRACT:
A longitudinal bearer of a motor vehicle frame, constructed as hollow profile which is provided with places for the introduction of chassis forces into the frame and into the longitudinal bearer and which includes a longitudinal bearer section arranged outside of the introduction places and dissipating deformable impact energy; this longitudinal bearer section, by reason of a differing wall thickness progress, has a resistance to buckling that increases in the direction toward the vehicle center; to that end at least the longitudinal bearer section located outside of the force introduction places is longitudinally subdivided over its length at least into two bearer parts consisting of sheet-metal profile members which are connected with each other along longitudinal seams, whereby the sheet-metal members have different wall thickness while the longitudinal seams extend obliquely to the longitudinal axis of the longitudinal bearer section such that the sheet-metal bearer member with greater wall thickness has a greater share in the circumference of the longitudinal bearer section in areas thereof located nearer the vehicle center than in areas thereof located nearer the end of the vehicle.
