摘要： A B column of a motor vehicle having a high strength and rigidity in the attachment area of door hinges and door locks and able to protect the occupants of the vehicle in the event of a side crash is provided. The B column includes a reinforcement plate, which extends over the entire height of the B column. Because the requirements for this reinforcement plate are not equally great in all areas, the reinforcement plate is a reshaped tailored rolled blank. The tailored rolled blank is produced by flexible rolling and has different thicknesses transversely to the rolling direction. It is thus especially thick in the areas on which especially high strength and rigidity requirements are placed, while it is implemented as correspondingly thin in the areas which must only fulfill low strength and rigidity requirements.
