BUMPER BEAM FOR VEHICLE CAPABLE OF PREVENTING THE GENERATION OF UNEVEN DENT BY INDUCING THE SPOKE WIRE CONVERGING PHENOMENON TO BE ABSORBED IN A BEAD UNIT

摘要

PURPOSE: A bumper beam for vehicle is provided to enhance the corrosion performance by increasing the strength of bumper beam by a bead unit, and to increase the welding performance by evening the welding portion at the time of welding various components.;CONSTITUTION: The bumper beam for vehicle has a closed section and is made up by regularly forming a bead unit(B) along the inner section of curvature diameter direction. The bead unit consists of neighbored numerous grooves which are formed on the inner side section of curvature diameter direction along the length direction to be spaced by predetermined distance.;COPYRIGHT KIPO 2013
