The invention relates to a lifting door assembly (1) comprising a lifting door (2), in particular a fast-moving industrial door, having a door leaf (21) which in the closed condition of the lifting door (2) covers a door aperture, and a door lintel sealing device (3) disposed in the area of a door lintel and mounted so as to produce a sealing effect between the door leaf (21) and the door lintel in a sealing position when the lifting door (2) is in the closed condition. The lifting door assembly (1) is characterized in that the door leaf is guided laterally such that in the open position, it is wound free of contact in the area of a door lintel, and in that in the sealing position, the door lintel sealing device (3) rests on a horizontal lateral edge surface of the door leaf (21) adjacent the door lintel. The invention further relates to such a door lintel sealing device. The invention allows to improve a lifting door assembly (1) such that particularly reliable sealing may be obtained with it in the area of the door lintel.

L'invention concerne un système de porte relevable (1) comprenant une porte relevable (2), en particulier une porte industrielle à grande vitesse, pourvue d'un panneau de porte (21) qui recouvre une ouverture de porte lorsque la porte relevable (2) est à l'état fermé, ainsi qu'un dispositif d'étanchéité supérieur (3) qui est disposé dans la région du linteau de porte et qui est monté de façon à assurer l'étanchéité entre le panneau de porte (21) et le linteau de porte dans une position d'étanchéité lorsque la porte relevable (2) est fermée. Ce système de porte relevable (1) se caractérise en ce que le panneau de porte est guidé latéralement de telle sorte qu'il soit enroulé sans contact dans la région du linteau de porte dans la position ouverte et en ce que le dispositif d'étanchéité supérieur (3) s'appuie contre une surface horizontale de bord latéral du panneau de porte (21) adjacente au linteau de porte dans la position d'étanchéité. L'invention concerne en outre un dispositif d'étanchéité supérieur de ce type. L'invention permet d'améliorer un tel système de porte relevable (1) de sorte qu'une étanchéité particulièrement fiable puisse être obtenue dans la région du linteau de porte.
