ABSTRACT:
An air outlet having a housing with stationary and swivelling lamellae which are arranged to influence air circulation. the stationary lamelae are arranged parallel to each other. The swivelling lamellae are pivotally supported in the housing about their respective swivel axis which are parallel to each other and perpendicular to the stationary lamellae. Each swivelling lamella includes first and second cooperating partial lamellae, each of which includes at least one lamellar tongue. Each tongue of the first partial lamella is positioned adjacent to a tongue of the second partial lamella such that the tongues are arranged to alternate with each other and operatively associate a respective swivelling lamellae with stationary lamellae. The first and second cooperating partial lamellae of each swivelling lamella are coupled to each other to permit independent displacement of each partial lamella so that the outlet may be adjusted to diffuse the air passing therethrough.
