The present invention relates to an impact absorbing safety bar for a vehicle door and, more specifically, relates to an impact absorbing safety bar with reinforced creases for a vehicle door. To achieve this, the impact absorbing safety bar for a vehicle door of which one side of a cross section is opened comprises: a first outward crease portion (120) in which a protrusion continued along a longitudinal direction of the safety bar protrudes outwards in at least a portion on an external surface of the safety bar; and a second outward crease portion (130) in which a protrusion continued in an orthogonal direction of the longitudinal direction is formed. Moreover, the safety bar comprises: a first inward crease portion (140) in which a protrusion continued along a longitudinal direction of the safety bar protrudes inwards in at least a portion on an external surface of the safety bar; and a second inward crease portion (150) in which a protrusion continued in an orthogonal direction of the longitudinal direction is formed.
본 발명은 자동차 도어의 충격흡수용 안전바에 관한 것으로, 보다 상세하게는 보강주름이 형성된 자동차 도어의 충격흡수용 안전바에 관한 것이다. 이를 위해, 단면 일측이 개방된 자동차 도어의 충격흡수용 안전바에 있어서, 안전바의 외면중 적어도 일부에는, 안전바의 길이방향을 따라 연속된 돌기가 외향 돌출된 제 1 외향주름부(120); 및 길이방향의 직각방향으로 연속된 돌기를 형성하는 제 2 외향주름부(130);가 형성되거나 또는 안전바의 외면중 적어도 일부에는, 안전바의 길이방향을 따라 연속된 돌기가 내향 돌출된 제 1 내향주름부(140); 및 길이방향의 직각방향으로 연속된 돌기를 형성하는 제 2 내향주름부(150);가 형성된다.
