The present invention relates to, as a vehicle wiper blade having two wiping parts, a vehicle wiper blade including an idealistic dual rubber blade. In a dual rubber blade having a structure in which an outer-side wiping blade of a front wiping part in a direction of a wiping operation effectively removes dirt from a glass surface, and simultaneously, an inner-side wiping blade of a rear wiping part wipes water from the glass surface, when the pressure provided by a wiper arm is relatively low, a high rate of pressure is applied to the inner-side wiping blade of the rear wiping part, and when the pressure provided by the wiper arm is relatively high and a glass surface contact angle of an inner-side wiping contact surface of the rear wiping part decreases to a critical angle, a stopping part of the front wiping part begins to be in close contact with the upper end of the rear wiping part to distribute pressure applied to the rubber blade to the two wiping parts to balance the pressure, thereby minimizing deformation of rubber blade wiping parts even under excessive pressure and ensuring stable wiping properties.

    본 발명은 두 개의 닦임부를 가진 차량용 와이퍼블레이드로서, 와이핑 작동 진행 방향의 앞쪽 닦임부의 외측닦임날이 유리면의 오물을 효과적으로 제거하면서 뒤쪽 닦임부의 내측닦임날은 유리면에서 물을 와이핑하는 구조의 이중고무블레이드에 있어서, 와이퍼암의 제공 압력이 상대적으로 낮은 경우에는 뒤쪽 닦임부의 내측닦임날에 높은 비율의 압력이 작용되도록 형성 위치시키고, 와이퍼암의 제공 압력이 상대적으로 높아서 뒤쪽 닦임부 내측닦임접촉면의 유리면 접촉각이 임계각도로 작아지면 앞쪽 닦임부의 멈춤부가 뒤쪽 닦임부 상단에 밀착되기 시작하여 고무블레이드에 가해지는 압력을 두 개의 닦임부로 분산시켜 압력 균형을 잡아주어 과도한 압력아래에서도 고무블레이드 닦임부의 변형을 최소화시키고 안정적인 닦임성을 확보하는 이상적인 이중고무블레이드를 구비한 차량용 와이퍼블레이드에 관한 것이다.
