Abstract: A bumper beam includes an outer portion and an inner portion each extending between a top end and a bottom end. At least one of the outer portion or the inner portion includes a pair of geometrical features each of which are disposed in spaced relationship to one another and adjacent a respective one of the top or bottom ends. A top wall and a bottom wall each extend from one of the geometrical features to the other of the outer portion or the inner portion to interconnect the outer and inner portions of the bumper beam. The geometrical features can be varied in size and shape to change and tune the energy absorption properties of the bumper beam and ultimately provide for a bumper beam that is adaptable and flexible over a range of vehicle applications.
