  • Vehicle door impact beam arrangement
    Patent number: 6890019
    Abstract: A vehicle door includes an inner panel, an outer panel operatively connected to the inner panel, and an impact beam. At least a portion of the impact beam is outboard of the outer panel to enable a thinner and more compact door compared to prior art doors. A rub strip is preferably attached to the impact beam to form a preformed part. The rub strip protects the door from damage resulting from minor impacts and conceals the impact beam from view.
