BUMPER REINFORCEMENT FOR VEHICLES

The present invention relates to a bumper reinforcement for vehicles having a fixing portion 11 to be fixed to a vehicle structural member at a part of the bumper reinforcement in a longitudinal direction. The bumper reinforcement is constituted by an integrally molded product obtained by deforming a hollow extruded product by plastic working. When the fixing portion 11 and vicinities thereof is defined as a reinforced portion 1, light-weighted portions 21 and 22 smaller in second moment of area and cross-sectional area than the reinforced portion 1 are provided at at least a part of a non-reinforced portion constituted by a portion other than the reinforced portion. This makes it possible to decrease the number of parts and trim the weight while securing strength.
