In order to prevent pressure and/or suction effects being transmitted via the door or window seals into the interior of a train when trains pass, particularly in tunnels, a projecting shoulder (5) is provided on the door frame (6) against which lips (3, 4) of the seal (1) attached to the door (2) rest on both sides, whereby, in the event of pressure from outside, one lip (3) is pressed against the shoulder (5) while, in the event of suction from outside, the other lip (4) is pressed against the shoulder (5). <IMAGE> |
