A formed beam for use as a vehicle bumper having an elongated body exhibiting front and rear opposing surfaces and top and bottom surfaces interconnecting the front and rear surfaces, such that the beam defines a swept shape between first and second opposite ends. A plurality of spaced apart and transverse extending beads are formed upon the top extending surface of said beam and at least a portion of one of the front and rear surfaces are inwardly displaced relative to each other and during formation of an arcuate profile to the beam, and such that the front and rear surfaces exhibit at least partially non-parallel surfaces.

Crushed profile bumper and method for producing

A bumper beam and method of manufacture which includes roll-forming the bumper beam with a constant longitudinal cross section, and then reforming the roll-formed beam to form a tubular bumper beam having a constant area. The bumper beam area is designed to incorporate a longitudinal 'curvature' to form angular surfaces consistent with many modern automobile fascias, thereby, enabling high impact absorption efficiency.

Wishbone shaped vehicle bumper beam

A bumper system for an automotive vehicle includes a rolled steel tube having a box or C-shaped cross section fixed to the forward ends of the side rails of the vehicle so as to extend transversely to the vehicle's longitudinal axis. The forward surface of the vehicle is formed by a plastic fascia which may have sloped surfaces for styling or aerodynamic reasons. The space between the forward end of the bumper bar and the fascia is filled with foam intended to absorb energy in an impact. To better match the sloped sections of the fascia, certain sections of the bumper bar are twisted about the longitudinal axis of the bar to create surfaces inclined relative to the vertical. The bars are formed by roll forming a steel web into an elongated member having generally vertical opposed faces. A section of the rolled member is heated above a metallurgical transition temperature. Then sections to be inclined are twisted about the longitudinal axis of the bumper bar in a die forming station and are then quenched to form a hardened steel member.
