Abstract

본 발명은 도어상부의 보강구조에 관한 것으로 종래에는 예시도면 제1도에서와 같이 도어(10)의 상단부에 내 · 외측벨트보강판(18)(16)만으로 도어(10) 상부의 측면충격에 대하여 보강시켜 그 충격에 대한 별다른 효과가 없고 특히 그 충격을 도어(10) 전체로 분산시키지 못함에 따라 그 충격에 대한 탑승자의 인명피해가 큰 문제점이 있었다.The present invention relates to a reinforcing structure of the upper part of the door. Conventionally, as illustrated in FIG. 1, the inner side and outer belt stiffening plates 18 and 16 of the upper part of the door 10 are used for the side impact of the upper part of the door 10. There was no significant effect on the impact by reinforcing, and in particular, the impact of the occupant on the impact was not great because the impact was not distributed to the entire door 10.

따라서 본 발명은 예시도면 제2도 및 제3도에서와 같이 도어(10)의 종방향으로 요철형상의 절곡부위가 형성되어 프레임과 같은 역할을 하는 절곡보강판(20)을 내측벨트보강판(18)의 하단과 인너패널(14)의 상부에 용접시켜 상기 폐단을 해소시킨 것이다.Therefore, in the present invention, as shown in FIGS. 2 and 3 of the exemplary drawings, the bent portion of the concave-convex shape is formed in the longitudinal direction of the door 10 so that the bending reinforcement plate 20 serving as a frame may have an inner belt reinforcement plate ( The lower end of 18) and the upper part of the inner panel 14 are welded to eliminate the closed end.
