Abstract:
1. A three-dimensional joint structure made of two hollow profiles, of a support frame for vehicles, comprising: a first elongated hollow profile having a cross-section having at least one planar side and a separating cut extending in one single cross-sectional plane around a portion of the circumference of the first hollow profile to define a web lying on the planar side, the first hollow profile being bent around the web to define two profile sections at an angle relative to one another and connected by the web, the two profile sections having ends formed by the separating cut and each end comprising projecting edge regions; and a second elongated hollow profile having a cross-section having at least two directly neighboring planar sides, which press against the projecting edge regions of the two profile sections, the first and second hollow profiles being integrally joined to one another between the projecting edge regions of the two profile sections of the first elongated hollow profile and the two neighboring planar sides of the second hollow profile, wherein the projecting edge regions of the first hollow profile are formed by quadrilateral cutouts cut along the separating cut and disposed symmetrically to the one single cross-sectional plane, and wherein each cutout is located and shaped to correspond to a location and radius of a longitudinal edge of the first hollow profile and to extend over the entire edge.
