Description

The invention relates to a motor vehicle comprising a body with a roof frame comprising two roof frame sections extending on both sides in the longitudinal direction of the vehicle, and a headliner arranged below the roof. Motor vehicles typically have a ventilation system that allows air to enter the vehicle interior. The air flows into the cabin through air vents distributed throughout the vehicle. Ventilation of the front area, where the driver and front passenger sit, is usually achieved via air vents located on the left and right sides of the dashboard, as well as above or within the center console. A blower, part of the ventilation system, draws air through ducts to the adjustable air vents, from where it is blown into the cabin. Because these air vents are positioned in front of the driver and front passenger, they are exposed to the airflow from the front or at a slight angle. This can provide a degree of comfort, especially when the air is cooled, as the occupants can be directed more or less directly at the airflow. However, not everyone finds this pleasant, so the blower speed is often turned down significantly to avoid a draft, or the air vents are adjusted so that the air is blown past the occupants. Both of these factors ultimately have a negative impact on the cooling effect and therefore on comfort. If the fan speed is low and the air volume is low, only weak cooling is possible, and the sides of the upper body, in particular, receive little to no cooling, leaving them more or less exposed to sunlight through the windows. Positioning the fans to the side also results in only a reduced cooling effect, if any at all, as the cool air simply flows into other areas of the room. Out of DE 10 2008 005 894 A1 A vehicle is known in which air can be blown downwards from the area of the side roof pillar, meaning that the air flows downwards to the side of the person sitting in the adjacent seat. Also DE 37 44 500 A1 Disclosing a vehicle in which such an air duct is provided, wherein a corresponding pipe or hose with corresponding outlet openings is installed on the roof side. Further prior art is shown by the DE 101 40 387 A1 . The invention is based on the problem of providing a motor vehicle with a simply designed means of improved ventilation in the area of the vehicle sides. To solve this problem, the invention provides a motor vehicle comprising a body with a roof frame comprising two roof frame sections extending longitudinally on both sides of the roof, and a headliner arranged below the roof, the headliner being connected to the roof frame section by its side edges via an elongated connecting element, wherein an air duct extending longitudinally in the direction of the vehicle is formed on one or both sides of the vehicle, which is bounded by the roof frame section, the headliner and a sealing element extending between the headliner and the roof frame section and which communicates with the vehicle interior via one or more ventilation openings. The vehicle according to the invention features an air duct provided on at least one side, preferably on both sides of the vehicle, which is bounded in a very simple manner by a roof frame section already present on the vehicle (i.e., a body-side component), the headliner, and a sealing element extending between the headliner and the roof frame section. This air duct, extending in the longitudinal direction of the vehicle, is therefore bounded and defined by components that are already present on the vehicle. Only the sealing element, which limits the duct to the vehicle interior, needs to be provided additionally. This means that the integration of such a roof-frame-side air duct is achieved in a simple manner. This air duct, which is naturally connected to a corresponding supply duct so that air is supplied to it via a blower or similar ventilation device, communicates with one or more ventilation openings leading to the vehicle interior, allowing the air to be blown into the vehicle interior. Since the air duct is positioned on a roof section directly adjacent to a side of the vehicle, these ventilation openings are necessarily also located on that side. This causes the air exiting them to flow downwards, along the side of the vehicle, including the adjacent window and interior trim. Consequently, a lateral curtain of air flows downwards over the window and door trim, providing very pleasant lateral cooling, as well as any potential overhead cooling. This prevents overheating caused by solar radiation entering through the window pane and the heating of the trim panels, etc. This means that, especially in summer, a corresponding curtain of cool air can be created parallel to the side window, providing pleasant cooling. The occupant can then adjust the actual front ventilation via the dashboard air vents to a lower setting, precisely because of the cooling air curtain from the side. Furthermore, since the amount of cool air blown out, forming the air cu
