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.

Claims

exact text as granted — not AI-modified
We claim: 
     
         1 . A bumper beam comprising:
 an outer portion and an inner portion each extending between a top end and a bottom end;   said outer portion including a first pair of geometrical features each disposed in spaced relationship to one another and adjacent a respective one of said top or bottom ends;   said inner portion including a second pair of geometrical features each disposed in spaced relationship to one another and adjacent a respective one of said top or bottom ends; and   a top wall and a bottom wall each extending between one of said first pair of geometrical features and one of said second pair of geometrical features to interconnect said outer and inner portions of the bumper beam.   
     
     
         2 . A bumper beam as recited in  claim 1 , wherein each of said first and second pairs of geometrical features having a polygonal cross-sectional shape with one side being open towards a respective top or bottom end of said inner or outer portion. 
     
     
         3 . A bumper beam as recited in  claim 1 , wherein each of said geometrical features having a circular cross-sectional shape. 
     
     
         4 . A bumper beam as recited in  claim 1 , wherein each of said geometrical features having a semi-circular cross-sectional shape.
