摘要

The cross beam (12) has passage regions (20, 22) provided with air flow openings (24, 26). A central region (30) is inwardly connected to the passage regions in a vehicle transverse direction. Outer regions (32, 34) are outwardly connected to the passage regions and free from the air flow openings. Screwing apertures (18) are arranged in the outer regions, where the cross beam is fastened at a longitudinal beam over the screwing apertures. A profile is designed as an extruded profile and comprises chambers with a closed hollow cross section running in a vehicle transverse direction.
