Abstract:
There is described a closure unit (14) for an air inlet of a motor vehicle which comprises three closure flaps (18, 22, 26) which can be pivoted about a rotation axis (16, 20, 24). In a closed position, the closure flaps (18, 22, 26) close the air inlet and a closure flap which is referred to as a second closure flap (22) abuts a closed position stop (36). In an open position, the closure flaps (18, 22, 26) release the air inlet and a closure flap which is referred to as the third closure flap (26) abuts an open position stop (40). Furthermore, a method for detecting defective closure flaps (18, 22, 26) of such a closure unit (14) is explained. Furthermore, a motor vehicle having one or more air inlets is presented, wherein at least one of the air inlets is provided with such a closure unit (14).
