Automobile framework stiffener, framework and method for fixing such a stiffener to a framework

摘要

The stiffener has longitudinal parts (1, 2), and longitudinal edges (5, 6) that are opposite to longitudinal parts. The longitudinal parts are welded together to form the stiffener, where the parts has different rigidity. Sheet thickness of the part (1) is higher than sheet thickness of the part (2). Free longitudinal edges (3, 4) of the parts are folded to form a coupling surface, where the edge (3) is folded towards an interior of the stiffener. The edge (4) is folded towards an exterior of the stiffener. Independent claims are also included for the following: (1) a framework comprising a stiffener (2) a method for fixing a stiffener on a framework.
