Abstract
Abstract In an air outlet device, a closure flap (9) is pivotably mounted in a houg body (1). The closure flap can be tilted in front of an air passage opening (3) by means of an actuating part (14). To avoid the closure flap (9), in its open position, taking up a considerable amount of space in the air exit shaft (4) and in order to keep the number of components required small, the closure flap (9) is of circular ring segment-shaped design in cross-section. The pivot axis of the closure flap (9) lies in the center point of the radius of the circular ring segment shape. The actuating part (14) is molded onto the closure flap (9).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
202 words
An air outlet device for a vehicle passenger compartment ventilation system, comprising: a housing body having an air passage opening and first and second opposing sidewalls; a closure flap of part-circular cross-section pivotably mounted on the housing to be tiltable about a pivot axis located downstream from the air passage opening, the pivot axis corresponding to the center of curvature of the closure flap; an actuating part arranged on the closure flap and pivotably mounted on the first sidewall so as to pivot about the pivot axis, said actuating part being wheel-shaped and having a slot formed therein, wherein the closure flap is in part pivotably mounted on the housing body through said pivotable mounting of the actuating part; a mounting arm arranged on said closure flap and pivotably mounted on said second sidewall, wherein said closure flap, said actuating part, and said mounting arm are formed as a one-piece molding; a first journal formed on said first sidewall which extends through the slot formed in the actuating part, said slot having ends which form stops for movement of the closure flap; a second journal formed on said second sidewall; and an air guide louver mounted on the first and second journals.
Claim 2
Dependent Claim
202 words
An air outlet device for a vehicle passenger compartment ventilation system, comprising: a housing body having an air passage opening and first and second opposing sidewalls; a closure flap of part-circular cross-section pivotably mounted on the housing to be tiltable about a pivot axis located downstream from the air passage opening, the pivot axis corresponding to the center of curvature of the closure flap; an actuating part arranged on the closure flap and pivotably mounted on the first sidewall so as to pivot about the pivot axis, said actuating part being wheel-shaped and having a slot formed therein, wherein the closure flap is in part pivotably mounted on the housing body through said pivotable mounting of the actuating part; a mounting arm arranged on said closure flap and pivotably mounted on said second sidewall, wherein said closure flap, said actuating part, and said mounting arm are formed as a one-piece molding; a first journal formed on said first sidewall which extends through the slot formed in the actuating part, said slot having ends which form stops for movement of the closure flap; a second journal formed on said second sidewall; and an air guide louver mounted on the first and second journals.
Claim 3
Dependent Claim
34 words
The air outlet device of claim 1, wherein the housing body is provided with an air exit passage having a part-cylindrical inner surface of a radius corresponding to the radius of the closure flap.
Claim 4
Dependent Claim
144 words
An air outlet device for a vehicle passenger compartment ventilation system, comprising: a housing body having an air passage opening and first and second opposing sidewalls; a closure flap of part-circular cross-section pivotably mounted on the housing to be tiltable about a pivot axis located downstream from the closure flap, the pivot axis corresponding to the center of curvature of the closure flap; an actuating part arranged on the closure flap and mounted on the first sidewall so as to pivot about the pivot axis, said actuating part having a slot formed therein; a first journal formed on said first sidewall which extends through the slot formed in the actuating part, said slot having ends which form stops for movement of the closure flap; a second journal formed on said second sidewall; and an air guide louver mounted on the first and second journals.
Claim 5
Dependent Claim
144 words
An air outlet device for a vehicle passenger compartment ventilation system, comprising: a housing body having an air passage opening and first and second opposing sidewalls; a closure flap of part-circular cross-section pivotably mounted on the housing to be tiltable about a pivot axis located downstream from the closure flap, the pivot axis corresponding to the center of curvature of the closure flap; an actuating part arranged on the closure flap and mounted on the first sidewall so as to pivot about the pivot axis, said actuating part having a slot formed therein; a first journal formed on said first sidewall which extends through the slot formed in the actuating part, said slot having ends which form stops for movement of the closure flap; a second journal formed on said second sidewall; and an air guide louver mounted on the first and second journals.
Claim 6
Dependent Claim
26 words
The air outlet device of claim 3, wherein the actuating part is of wheel or lever-shaped design and has the same radius as the closure flap.
Claim 7
Dependent Claim
38 words
The air outlet device of claim 3, wherein the actuating part is pivotably mounted on the housing body, the closure flap being in part pivotably mounted in the housing body through said pivotable mounting of the actuating part.
Claim 8
Dependent Claim
43 words
The air outlet device as claimed in claim 3, further comprising a mounting arm arranged on said closure flap and pivotably mounted on said second sidewall, wherein said closure flap, said actuating part, and said mounting arm are formed as a one-piece molding.
Claim 9
Dependent Claim
36 words
The air outlet device as claimed in claim 3, wherein the housing body is provided with an air exit passage having a part-cylindrical inner surface of a radius corresponding to the radius of the closure flap.
