Abstract
A three-dimensional joint structure of a support frame for vehicles can include two hollow profiles, of which the first hollow profile has at least one planar side and is cut through around its circumference except for a web lying in this planar side and is bent around this web. The second hollow profile has at least two planar sides that press against the ends of the first hollow profile resulting from the cutting and bending. The two hollow profiles are integrally joined to one another at the edge region of the ends.
