First claim
Opening claim text (preview).
What is claimed is: 1. A bumper back beam for a vehicle comprising: side portions connected to a vehicle body and formed of general plastic on both sides thereof; and an intermediate portion connecting the side portions on both sides thereof and formed of high-strength plastic and a predetermined section, both ends of which encroach into the side portions to form overlap sections having a hollow space enclosed by the side portion and the intermediate portion, wherein the side portion is connected to a side member of the vehicle body. 2. The bumper back beam for the vehicle of claim 1 , wherein each overlap section is a box portion having a predetermined space therein together with each side portion. 3. The bumper back beam for the vehicle of claim 1 , wherein a length of each overlap section in a left/right direction exceeds at least 5% or more of a length of each side portion in the left/right direction and does not exceed a maximum of 50%. 4. The bumper back beam for the vehicle of claim 2 , wherein a plurality of through-holes are formed passing through a side wall of the box portion so as to induce buckling of the box portion with respect to a collision load. 5. The bumper back beam for the vehicle of claim 2 , wherein bent grooves are continuously formed on a side surface forming the box portion at each side portion, which induce buckling of the box portion with respect to a collision load. 6. The bumper back beam for the vehicle of claim 4 , wherein a total sectional area of the through-holes is 5% to 50% of a sectional area of the side wall. 7. The bumper back beam for the vehicle of claim 1 , wherein the high-strength plastic which forms the intermediate portion is composite material combined with glass fiber, polypropylene (PP), and polyamide resin. 8. The bumper back beam for the vehicle of claim 1 , wherein the general plastic forming the side portions is the same material as any one of resins used in forming the high-strength plastic.
