Abstract: An intrusion beam structure for reinforcing a vehicle door includes an elongated member adapted to be attached to a surface of the inner panel of a door frame that is substantially parallel to the axis defined by the elongated member. The elongated member includes first and second end portions interdisposed by a middle portion. The end portions are substantially identical and each taper away from the middle portion. In a first embodiment, the elongated member is unitarily formed and has a substantially circular cross-section. In a second embodiment, the elongated member includes first and second bar portions which substantially traverse the entire length of the elongated member and are disposed substantially parallel to each other. The first and second bar portions are separated by an intermediate structure.

Abstract: An intrusion beam structure for reinforcing a vehicle door includes an elongated member adapted to be attached to a surface of the inner panel of a door frame that is substantially parallel to the axis defined by the elongated member. The elongated member includes first and second end portions interdisposed by a middle portion. The end portions are constructed of a first material, and the middle portion is constructed of a second, different material. The elongated member is unitarily stamped from a composite sheet and is formed to include first and second mounting members, each having a planar surface adapted to mount to the inner panel.
