Abstract
The present invention relates to a door sealing device sealing a gap between a door leaf and a frame for a rail vehicle, where the door sealing device includes a flexible tubular hollow chamber formed by two opposite contact walls and two opposite side walls, where, in the mounted state of the door sealing device, a first contact wall of the contact walls faces the door leaf and a second contact wall of the contact walls faces the frame so that the hollow chamber is subject to compression in the event of a closing motion of the door leaf, thereby moving the contact walls towards each other, and where the sidewalls are formed to be buckled along predetermined buckle lines in response to the compression.
