Abstract:
An air flow arrangement for feeding air to an interior of a motor vehicle, comprising:a housing; vertical and horizontal air guiding vanes swivelably arranged in the housing; and an adjusting element for controlling swiveling of the vanes; wherein, the housing is fastenable in an opening of a column paneling that is connectable with a column of the vehicle; the housing has a vertically aligned air guiding duct in the vehicle column; the air guiding duct includes lower and upper duct sections; the lower duct section has an adjusting flap that can be swiveled by means of an operating element about a bearing axis into a horizontal closed position, a vertical open position and an intermediate position; the adjusting flap can be operated via the operating element, by way of a reversing bow that is connected with a crank of the flap and can be swiveled at the housing in a bearing; the upper duct section includes the vertical and horizontal air guiding vanes; the vertical air guiding vanes are composed of a first vane unit which is arranged in a perpendicular transverse plane of the vehicle and includes a plurality of air guiding vanes that are swivelable about a longitudinal axis thereof, and a second vane unit which is arranged approximately perpendicular to the first vane unit in a vertical longitudinal plane of the vehicle and includes a plurality of air guiding vanes that are swivelable about a longitudinal axis thereof; by way of said adjusting element all swivelable vanes can be jointly moved into a first position in which all of said swivelable vertical air guiding vanes are in an open position, and a second position, in which the swivelable vertical air guiding vanes of the first vane unit take up an open position and the swivelable vertical air guiding vanes of the second vane unit take up a closed position; the first vane unit includes a single stationary vane which is fixed in an open position, is arranged directly adjacent to a housing wall of the air outlet opening and cannot be swiveled into an open or closed position; the horizontal air guiding vanes are disposed in said upper duct section upstream of said vertical air guiding vanes and are swivelable about respective longitudinal axis thereof; and said adjusting element is mounted on one of said swivelable vertical air guiding vanes in said first vane unit, and is coupled to one of said horizontal air guiding vanes via a rack and pinion gear device.
