摘要

The invention relates to a tubular member, especially for safety steering columns for motor vehicles, made of wound fiber-reinforced materials. The winding angle of the fibers or fiber belts amounts to essentially +/-45 DEG relative to the tube's longitudinal axis. For taking up high torsional moments and simultaneously low compressive and buckling or bending loads, the tubular member (1) has an expanded outwardly bulging section (3) extending around the entire circumference of the tubular member. This bulging section is preferably a double conical outward bulge. The fibers (2) cross each other at an angle of essentially 90 DEG even in the region of the outwardly bulging section (3), which means that the winding angle of essentially +/-45 DEG to the tube's longitudinal axis is maintained in the region of the outwardly bulging section (3).
