Abstract: An air guiding element for improved flow over a gap between a tractive vehicle and a trailer vehicle is described, wherein the air guiding element can be mounted on the tractive vehicle or the trailer vehicle and has a flexible and airtight air cushion which is connected to a filling channel. The problem of providing a largely low-maintenance and operationally safe air guiding element, which can be installed independently of the compressed air supply of the tractive vehicle, for improved flow over the gap between a tractive vehicle and a trailer vehicle is addressed. The problem is solved by an air guiding element in which the filling channel has an air entry opening oriented in the direction of travel (F) on the side of the filling channel facing away from the air cushion, the air entry opening being arranged in such a way that the air cushion is filled exclusively by a dynamic pressure of the relative wind.
