Generally, the vehicle is provided with a door for getting on and off the occupant. In addition, a door impact bar is provided inside the door to reduce deformation of the vehicle body when a side collision of the vehicle occurs. This reinforces the strength of the door so as to minimize the impact of the impact to the passenger when the door is collided, thereby reducing the injury of the passenger.
That is, the door of the vehicle is provided with a pipe-shaped impact bar arranged laterally on the door panel, and a door impact bar bracket installed to fix the door impact bar to the door panel. When a collision occurs in the door in this state, the door panel and the impact bar are broken and the impact is absorbed, thereby minimizing the injury of the passenger.
Conventional door impact bar brackets were attached to the door impact bar by welding. Therefore, heat damage to the door impact bar bracket and the door impact bar occurs due to welding, and the welded portion is a starting point of collision when the side collision of the vehicle occurs. That is, there is a problem that the strength of the door impact bar bracket and the door impact bar are significantly reduced due to welding.
