The present invention relates to a bumper beam for a vehicle, which comprises: a protruding unit protruding to a front area; and an upper buffering unit and a lower buffering unit of which a cross-section has triple bent portions in an almost square shape to enable an upper shock absorbing space and a lower shock absorbing space to be formed in each of an upper portion and a lower portion of the protruding unit. According to the present invention, one panel can be frequently molded to be bent using a roll-forming method to form the cross-section in a B shape. After finishing the molding work, a structure is formed to have a predetermined curvature in accordance with a front shape of the vehicle using the length predetermined in the vertical direction. Therefore, each of an upper portion and a lower portion of the bumper beam for the vehicle can have a shock absorbing space to produce a B shape. Thus, collision energy occurring when the vehicle is crashed can be effectively absorbed, thereby preventing damage to a vehicle body and safely protecting a driver.

    차량용 범퍼빔에 관한 것으로, 전방을 향해 돌출 형성되는 돌출부, 상기 돌출부의 상단과 하단에 각각 상부 및 하부 충격흡수공간을 형성하도록 단면이 대략 사각 형상으로 3중 절곡 형성되는 상부 및 하부 완충부를 포함하여 하나의 패널을 롤 포밍 성형방식으로 여러 차례 절곡 성형해서 단면이 B 형상으로 형성되고, 성형 작업 이후에 수평 방향으로 미리 설정된 길이를 가지고 차량의 전방 형상에 따라 미리 설정된 곡률을 갖도록 형성되는 구성을 마련하여, 차량용 범퍼빔의 상부와 하부에 각각 충격흡수공간을 마련해서 B 형상으로 제조함으로써, 차량 충돌시 발생하는 충돌 에너지를 효과적으로 흡수해서 차체의 손상을 방지하고 탑승자를 안전하게 보호할 수 있다는 효과가 얻어진다.
