## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

The bent structure of claim 2, wherein the upper bracket supports a lateral surface of the roof panel from below the roof panel.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 4)

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.
