The invention concerns manufacturing of a specially shaped roll-over bar, the design of such a roll-over bar and the use of such a roll-over bar, where the geometric shape can vary in cross section and design, can be provided from simple tube-shaped members and manufactured more cost-effectively and with a more uniform quality. The roll-over bar (1A) encompassing a U-shaped bent tube (2) made from a single piece of tubing (1) with substantially parallel outer leg sections (2a, 2b) plus a middle bridge section (2c) formed substantially by indentation of side areas (3a, 3b) and partially by inward bending (3c) of the bending side (3). |
