Base structure for motor vehicle, is made of fiber composite material, and change in cross-section is formed, such that crash behavior of base structure is controlled

摘要

The base structure (1) is made of fiber composite material. A change in cross-section (6) is formed, such that the crash behavior of the base structure is controlled. A seat cross beam (5) is provided, which has a vertical section (7) and a horizontal section (8), where both the sections are connected together by a radius (9). The change in cross-section runs partially inwards to the radius.
