Abstract
An upset tube for accommodating impact energy in a motor vehicle, preferably head-on collisions, which may be used both in the bumper bar or propeller shaft of a motor vehicle, has one bead angled with sides with different angular values. The angles enable a predetermination of the region of nominal fracture. After having been sheared off, the upset tube is able to destroy a defined amount of friction energy.
