  • Vehicle bumper beam with non-uniform cross section
    Patent number: 6349521
    Abstract: A method includes rollforming and sweeping a tubular beam with a constant longitudinal cross section, and then reforming the tubular beam 10 to form a tubular beam having a non-constant cross section. The non-constant cross sections have specific shapes chosen to provide particular structural properties and surfaces along the reshaped beam, and also to provide a stylized appearance, such that the reformed beam is useful as a vehicle bumper. In particular, the reshaped beam includes integrally formed vehicle mounting structure, angled end sections forming aerodynamic but impact-resistant bumper ends, and a high-energy absorbing but flexible center section.
