Motor vehicle door with a lateral impact protection device

摘要

A motor vehicle door has a lateral impact protection device with a lateral impact beam and a fastening device to connect the lateral impact beam to a door part. The fastening device has a fastening bracket being a cast part and is connected to the door part. The fastening bracket has a fork-shaped seat for receiving the lateral impact beam. A holding bolt passes through the lateral impact beam and the fork-shaped seat. The fork-shaped seat contains at least two inner surfaces which face the lateral impact beam and lie opposite one another with a spacing and a fork bottom. For ease of production, the fork-shaped seat widens with its inner surfaces in its direction pointing away from the fork bottom. The inner surfaces are configured as unfinished cast surfaces, and the lateral impact beam has a trapezoidal cross section adapted to the widening seat.
