Abstract
A bumper system for vehicles includes a tubular beam having front, top, bottom, and rear walls, and further having open tubular ends. The bumper system further includes a pair of mounting brackets each attached to the rear wall and extending around the associated ends and forwardly to a location where it attaches to the front wall of the one end. One or more crush initiating apertures are formed in one or more of the walls of the ends of the beam to provide more controlled energy absorption upon corner impost so as to reduce or better control damage to the vehicle's frame.
