Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
An air outlet for interior spaces comprising: a. a housing; b. a plurality of stationary lamellae disposed parallel to each other in said housing; and c. a plurality of swivelling lamellae each having a swivel axis and being pivotally mounted in said housing for rotation about its respective swivel axis, said swivel axes being parallel to each other and perpendicular to said stationary lamellae, each swivelling lamella including first and second partial lamellae mounted for independent swivelling, said first and second partial lamellae including tongues disposed between said stationary lamellae such that the tongues of said first partial lamella alternate with the tongues of said second partial lamella.
Claim 2
Dependent Claim
108 words
An air outlet for interior spaces comprising: a. a housing; b. a plurality of stationary lamellae disposed parallel to each other in said housing; and c. a plurality of swivelling lamellae each having a swivel axis and being pivotally mounted in said housing for rotation about its respective swivel axis, said swivel axes being parallel to each other and perpendicular to said stationary lamellae, each swivelling lamella including first and second partial lamellae mounted for independent swivelling, said first and second partial lamellae including tongues disposed between said stationary lamellae such that the tongues of said first partial lamella alternate with the tongues of said second partial lamella.
Claim 3
Dependent Claim
21 words
The air outlet of claim 1 wherein each lamellar tongue includes a slot into which one of said stationary lamellae extends.
Claim 4
Dependent Claim
23 words
The air outlet of claim 2 further including first and second coupling shanks respectively pivotally coupling thereto the first and second partial lamellae.
Claim 5
Dependent Claim
23 words
The air outlet of claim 1 further including first and second coupling shanks respectively pivotally coupling thereto the first and second partial lamellae.
Claim 6
Dependent Claim
51 words
The air outlet of claim 4 wherein each first partial lamella of a respective swivelling lamella is coupled to one of said shanks at a first coupling point, the distance between each first coupling point and the swivel axis of the respective swivelling lamella varies from swivelling lamella to swivelling lamella.
Claim 7
Dependent Claim
51 words
The air outlet of claim 3 wherein each first partial lamella of a respective swivelling lamella is coupled to one of said shanks at a first coupling point, the distance between each first coupling point and the swivel axis of the respective swivelling lamella varies from swivelling lamella to swivelling lamella.
Claim 8
Dependent Claim
144 words
An air outlet for discharging air into the passenger compartment of a motor vehicle comprising: a housing; a plurality of stationery lamellae disposed parallel to each other in said housing; a plurality of swivelling lamellae each having a swivel axis and being pivotally mounted in said housing for rotation about its respective swivel axis, said swivel axes being parallel to each other and perpendicular to said stationary lamellae; each swivelling lamella including discrete first and second partial lamellae that are pivotally coupled to one another along a respective one of said swivel axes and independently mounted in said housing such that said first and second partial lamellae swivel independently of one another; and said first and second partial lamellae including tongues disposed between said stationary lamellae such that the tongues of said first partial lamella alternate with the tongues of said second partial lamella.
Claim 9
Dependent Claim
144 words
An air outlet for discharging air into the passenger compartment of a motor vehicle comprising: a housing; a plurality of stationery lamellae disposed parallel to each other in said housing; a plurality of swivelling lamellae each having a swivel axis and being pivotally mounted in said housing for rotation about its respective swivel axis, said swivel axes being parallel to each other and perpendicular to said stationary lamellae; each swivelling lamella including discrete first and second partial lamellae that are pivotally coupled to one another along a respective one of said swivel axes and independently mounted in said housing such that said first and second partial lamellae swivel independently of one another; and said first and second partial lamellae including tongues disposed between said stationary lamellae such that the tongues of said first partial lamella alternate with the tongues of said second partial lamella.
