A beam is provided for absorbing impact forces imparted to doors and sides of a vehicle body as a result of collisions from the side as well as from the front and rear of the vehicle. The beam ( 17, 18, 78, 88 ) is intended to protect people or goods inside the vehicle against personal injury or damage in the case of such an impact. The beam ( 17, 18, 78, 88 ) comprises at least one thin walled, closed profile roll formed member ( 52, 62, 72, 82 ) defining a cavity ( 63, 83 ). At least one wall of the member defines at least one longitudinally extending groove ( 53, 65, 73, 81 ). The beam ( 17, 18, 78, 88 ) may also be used as a standard building block for structural components. |
