Abstract
An energy absorber for a vehicle bumper system includes a plurality of crush boxes that are configured to absorb impact energy. Each of the plurality of crush boxes are generally hollow and have a front wall and a plurality of side walls integrally formed with and extending from the front wall to a rear of the energy absorber. A first crush box is separated from a second crush box by a distance such that an open space is defined between a side wall of the first crush box and a side wall of the second crush box. At least one rib extends between the side wall of the first crush box and the side wall of the second crush box in the open space to couple the first crush box to the second crush box. The at least one rib is integrally formed with the first crush box and the second crush box, and extends at least partially between the rear of the energy absorber and the front walls of the first and second crush boxes.
