Abstract
The door seal comprises a fixing element (20) for fixing to a door, a seal receiving element (40), a lowering mechanical unit (20) for lifting and lowering the seal receiving element (40) relative to the fixing element (20), and a sealing element (50) fixed to the seal receiving element (40). The sealing element (50) provides a first sealing line (54a) by means of a first sealing element portion (54) which can be lifted or lowered by means of the lowering mechanical unit, and the first sealing element portion (54) is a sealing lip and/or a sealing arc. The sealing element (50) provides a second sealing line (55a) by means of a second sealing element portion (55), said second sealing line running parallel to the first sealing line (54a). The second sealing element portion (55) has a first and a second side (52, 56), said first side (52) can be lifted and lowered by means of the lowering mechanical unit and said second side (56) is fixed in its position relative to the fixing element (20). In the lowered state, the first and the second sealing line (54a, 55a) seal against a surface which can be found outside of the door seal. Said seal allows a sufficient sealing of the gap between frames and doors when the seal is lowered even during a horizontal movement.
