Sealing profile made of an elastomer material, wherein the cross-section of the sealing profile incorporates a so-called underside that is intended for contact with the component part that is to be sealed and an upper side and two longitudinal sides opposing each other and wherein the sealing profile incorporates in its cross-section the following features: • a plurality of holes spaced apart from one another and referred to as "channels", • wherein a plurality of channels that form a row (8, 9) are arranged one beside the other • and a plurality of channels are arranged one above the other, • webs that extend between the channels, • wherein webs that are arranged one above the other in alignment form upright ribs (10, 11) • and webs that are arranged one beside the other in alignment form horizontal bridges, • the channels that are arranged one beside the other in a row (8, 9) are perpendicularly offset, wherein a lateral, outer channel is arranged lower than a channel that is arranged further inwards in the row (8, 9) so that the row (8, 9) curves upwards and then downwards in a bow shape, • two such bow-shaped rows (8, 9) are separated from each other by a bridge that is likewise bow-shaped and extends all the way through, • the channels are spaced apart from each other in a row (8, 9) and in rows (8, 9) that extend one above the other in such a way that they form first ribs that extend essentially perpendicularly and second ribs that extend diagonally to the side of this centre line and on one of the two sides of the profile cross-section relative to a perpendicular centre line that extends through the profile cross-section, • and a second rib extends from a lower end that is nearer the middle of the profile cross section to an upper end that lies sideways further outwards than the bottom end, characterised in that a first rib extends in the middle of the profile cross-section relative to the perpendicular centre line that extends through the profile cross section. • a plurality of holes spaced apart from one another and referred to as "channels", • wherein a plurality of channels that form a row (8, 9) are arranged one beside the other • and a plurality of channels are arranged one above the other, • webs that extend between the channels, • wherein webs that are arranged one above the other in alignment form upright ribs (10, 11) • and webs that are arranged one beside the other in alignment form horizontal bridges, • the channels that are arranged one beside the other in a row (8, 9) are perpendicularly offset, wherein a lateral, outer channel is arranged lower than a channel that is arranged further inwards in the row (8, 9) so that the row (8, 9) curves upwards and then downwards in a bow shape, wherein a lateral, outer channel is arranged lower than a channel that is arranged further inwards in the row (8, 9) so that the row (8, 9) curves upwards and then downwards in a bow shape, • two such bow-shaped rows (8, 9) are separated from each other by a bridge that is likewise bow-shaped and extends all the way through, • the channels are spaced apart from each other in a row (8, 9) and in rows (8, 9) that extend one above the other in such a way that they form first ribs that extend essentially perpendicularly and second ribs that extend diagonally to the side of this centre line and on one of the two sides of the profile cross-section relative to a perpendicular centre line that extends through the profile cross-section, • and a second rib extends from a lower end that is nearer the middle of the profile cross section to an upper end that lies sideways further outwards than the bottom end,
