Abstract
An air outlet includes an inner discharge zone (3) and an outer discharge zone (4) surrounding the inner discharge zone in the shape of a ring. Both discharge zones are subdivided into several air guide ducts (9) by air baffles (8). The air baffles (8) of the discharge zones are inclined relative to the axis (10) of the air outlet (1). The air baffles of the one discharge zone (3) are slanted in the opposite direction of the air baffles of the other discharge zone (4).
Claims13
An air outlet for ventilating an interior space of a motor vehicle, comprising:
- (a) an exhaust port divided into at least first and second level discharge zones, one zone concentrically surrounding the other, said port having a discharge axis directed toward the interior space of the motor vehicle;
- and
- (b) a plurality of air baffles subdividing each of said zones into a lattice form defining discrete air guide ducts, said baffles inclined to said discharge axis such that:
- (i) the air baffles dividing said first zone are inclined relative to said axis so as to impart a swirl to air being discharged in a first rotational direction;
- and
- (ii) the air baffles subdividing said second zone are inclined relative to said axis so as to impart a swirl to the air being discharged in the opposite rotational direction.
