Impact beam with bent structure and bending apparatus

Abstract

An impact beam having a bent structure is provided. The impact beam is mounted at a lateral portion of each door in a vertical direction of a vehicle body and supports the door in the vertical direction. An upper end of the impact beam extends to support a roof panel and a lower end of the impact beam extends to a lower roller mounting portion. The impact beam is bent in an L shape and a T shape based on a curvature of the door.

1 .- 5 . (cancelled) 
     
     
         6 . An apparatus for bending an impact beam, comprising:
 an upper die including therein a first concave portion that is recessed in a hemispheric shape, and having a first inclined portion that is recessed to have a predetermined angle with respect to the first concave portion; and   a lower die positioned below the upper die, having, at an upper side thereof, a second concave portion that is recessed in a hemispheric shape, and having, at an outer portion thereof, a second inclined portion that has an inclination that corresponds to the first inclined portion,   wherein the first inclined portion and the second inclined portion bend in a T shape by downward force of the upper die to position the impact beam positioned between the upper die and the lower die, and the first concave portion and the second concave portion bend the impact beam in an L shape.   
     
     
         7 . The apparatus of  claim 6 , wherein an interval between the first concave portion and the second concave portion is determined based on an L-shaped curvature of a door of a vehicle. 
     
     
         8 . The apparatus of  claim 6 , wherein an inclination angle of the first inclined portion and an inclination angle of the second inclined portion are determined based on a T-shaped curvature of a door. 
     
     
         9 . (cancelled)
