Abstract
Wide brackets of door impact beams are formed in a Z shape such that beam contact parts are extended horizontally in one direction above oblique force support parts and wide overlap parts are extended horizontally in the opposite direction below the oblique force support parts. Therefore, while an overlap section of a door with respect to a B pillar is further widened, a body frame and a B pillar of a 2-door coupe vehicle exhibit the same safety performance as a body frame and a B pillar of a 4-door sedan vehicle.

A door impact beam unit for a 2-door vehicle, comprising:
- a beam contact part including an end portion connecting a door outer panel and a door inner panel and at which an end portion of a door impact beam is positioned, inside the door outer panel, and having such an overlap length as to partially surround the end portion of the door impact beam;
- a wide overlap part maintaining a horizontal state in the opposite direction of the beam contact part, overlapping a stepped side overlap part of the door inner panel positioned at a B-pillar side extended part of a B pillar of a body frame, and having such an overlap length as to overlap the door inner panel;
- and
- a force support part integrally and continuously connecting the beam contact part and the wide overlap part and inclined to form a Z shape therebetween in such a manner that an overlap section of the wide overlap part is positioned at an end portion of the door inner panel.
