Abstract
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).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
138 words
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.
Claim 2
Dependent Claim
138 words
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.
Claim 3
Dependent Claim
21 words
The air outlet of claim 1 wherein the one surrounding discharge zone is surrounded by at least one additional discharge zone.
Claim 4
Dependent Claim
18 words
The air outlet of claim 1 wherein the enclosed discharge zone surrounds at least one additional discharge zone.
Claim 5
Dependent Claim
21 words
The air outlet of claim 2 wherein the at least one additional discharge zone is likewise subdivided into air guide ducts.
Claim 6
Dependent Claim
30 words
The air outlet of claim 3 wherein the subdividing air baffles of the at least one additional discharge zone are likewise inclined relative to the axis of the air outlet.
Claim 7
Dependent Claim
30 words
The air outlet of claim 5 comprising at least five discharge zones, wherein the subdividing air baffles of two or more contiguous discharge zones are slanted in the same direction.
Claim 8
Dependent Claim
28 words
The air outlet of one of claims 1 to 6 wherein the angle of inclination of the air baffles of a discharge zone vary in groups or segments.
Claim 9
Dependent Claim
30 words
The air outlet of one of claims 1 to 6 wherein inner and outer lateral walls of the air guide ducts are inclined outwardly relative to the air outlet axis.
Claim 10
Dependent Claim
15 words
The air outlet of one of the claims 1 to 6 wherein the air shape.
Claim 11
Dependent Claim
24 words
The air outlet of one of the claims 2-6 wherein the air guide ducts of the discharge zones are arranged in a rectangular pattern.
Claim 12
Dependent Claim
21 words
The air outlet of claim 10 wherein the air guide ducts of the discharge zones are arranged in a square pattern.
Claim 13
Dependent Claim
32 words
The air outlet of one of the claims 1 to 6 wherein within the enclosed discharge zone, an innermost, central discharge zone is arranged, whose air baffles are parallel to each other.
Claim 14
Dependent Claim
28 words
The air outlet of one of the claims 1 or 2 wherein the inclination of at least some air baffles of at least one discharge zone is adjustable.
