Abstract
Air flow control insertable into an air opening for controlling air flowing along an air flow direction, with a closure device including a cloth or fabric adjustable between an opening position releasing the air opening and a closing position at least partially closing the air opening by means of an adjustment device for selectively releasing and closing the air opening to change the air resistance and/or for thermal management of a downstream unit in the air flow direction. Various solutions are proposed to integrate the air control system in or behind an air grille, especially in very limited installation space.
Claims11
An air flow control for a vehicle comprising a frame surrounding an air opening for air flowing therethrough along an air flow direction, a closure device comprising a fabric or a tissue, which is adjustable by an adjustment device between an open position releasing the air opening and a closed position at least partially closing the air opening for selectively releasing and closing the air opening, the closure device comprising a self-winding fabric roller blind with a spring winding shaft extending transversely to the air opening and spring-biased on which the fabric is windable with a first fabric end, the adjusting device comprising a rotatably mounted adjusting spindle (24) extending also transversely and parallel offset to the spring winding shaft and having counter-rotating threaded portions at opposite ends, corresponding drivers running on the threaded portions, and the drivers being connected to a second fabric end of the fabric roller blind via connecting arms rotatably articulated to said drivers.
