  • Publication number: 20240010147
    Abstract: Provided are: a lightweight bumper reinforcement which, with respect to the load during a collision, exhibits high rigidity against a light load and, against a heavy load, is capable of plastic deformation to absorb collision energy while effectively transferring unabsorbed energy to a crash box; a method for manufacturing the same; and a resin reinforcement member for a bumper reinforcement. The bumper reinforcement of the present disclosure comprises a body portion extending along a vehicle width direction, and a resin reinforcement portion extending along the vehicle width direction and disposed on the vehicle body side relative to the body portion. The body portion has at least one first joint portion on the vehicle body side. The resin reinforcement portion has at least one second joint portion joined to the first joint portion, and one or more reinforcement ribs projecting on the vehicle body side and extending along the vehicle width direction.
