MOTOR VEHICLE BODY WITH A FLOOR WHICH HAS A TRANSVERSELY EXTENDED EXTRUDED PROFILE

摘要

In motor vehicle manufacturing nowadays, a floor panel having two side sills customarily extends in a motor vehicle body. In this case, the side sills are generally of shell-type construction. The problem addressed by the invention is to provide a motor vehicle body with a floor which has a small deformation travel in the event of a side crash. According to the invention, a floor (7) which consists of an extruded profile extends in the transverse direction (y) of the vehicle between two side sills (1). Said extruded profile has at least one hollow chamber (8), the longitudinal extent of which runs in the transverse direction (y) of the vehicle. If the extruded profile has a plurality of hollow chambers (8), the latter are arranged one behind another, as seen in the longitudinal direction (x) of the vehicle. Owing to the at least one hollow chamber (8), the floor (7) has a high degree of rigidity. In addition, the floor (7) can be composed of a light metal or a light metal alloy. The floor (7) is then extraordinarily light in relation to the high degree of rigidity thereof.
