Impact beam with bent structure and bending apparatus
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. An impact beam having a bent structure, comprising:
an upper end that extends to support a roof panel; and
a lower end that extends to a lower bracket,
wherein the impact beam is bent in a front-rear direction of the vehicle and a width direction of the vehicle based on a curvature of each door of a vehicle, and
wherein the impact beam is mounted at a door in a vertical direction of a vehicle body and supports the door in the vertical direction.
2. The bent structure of claim 1 , further comprising:
an upper bracket having a bent portion that accommodates the upper end of the impact beam,
wherein the upper bracket is mounted at an upper side of the door while overlapping the impact beam.
3. The bent structure of claim 2 , wherein the upper bracket supports a lateral surface of the roof panel from below the roof panel.
4. The bent structure of claim 1 , further comprising:
a lower bracket having an accommodating portion that accommodates the lower end of the impact beam,
wherein the lower bracket is mounted at a lower portion of the door so that the impact beam and the lower bracket are mounted to overlap each other.
5. The bent structure of claim 4 , wherein a lower roller is mounted on the lower bracket at a position opposite to the accommodating portion of the lower bracket.
