Energy management beam

An energy management system comprising:

• longitudinally extending beam having a front face that extends in a longitudinal direction of the beam, a first side wall and a second side wall;
• an energy absorber located adjacent the front face of the beam;
• and
• mounts engaging a rear of the beam for connecting the beam to a vehicle;
• the first side wall having a first U-shaped section spaced from the front face;
• and
• the second side wall having a second U-shaped section spaced from the front face;
• wherein the first side wall rolls to enlarge the first U-shaped section and the second side wall rolls to enlarge the second U-shaped section during an impact force directed against the front face of the beam.

An energy management system comprising:

• a longitudinally extending beam including a first beam portion and a second beam portion, a first one of the first beam portion and the second beam portion having a first face that extends in a longitudinal direction of the beam, a first side wall and a second side wall, a second one of the first beam portion and the second beam portion having a second face;
• that extends in a longitudinal direction of the beam
• the first side wall having a first U-shaped section spaced from the first face;
• and
• the second side wall having a second U-shaped section spaced from the first face;
• wherein the first side wall rolls to enlarge the first U-shaped section and the second side wall rolls to enlarge the second U-shaped section during an impact force directed against the first face of the first beam portion or the second face of the second beam portion.
