Abstract: An air vent for a motor vehicle includes a housing having an insert rotationally and/or pivotably supported in the housing about a bearing system with at least one assembly for guiding and/or deflecting a supplied air flow, and an element arranged centrally in the insert. The element is connected to the assembly for guiding and/or deflecting a supplied air flow. The bearing system is arranged on the central longitudinal axis of the housing and is carried out by a bearing. An optical fiber is accommodated in the bearing. For the at least regional lighting of the air vent, at least one light source is arranged in the housing on the central longitudinal axis upstream of the bearing system, such that the light emitted by the at least one light source is at least partially couplable, as needed, into the first optical fiber via a photometric coupling in the bearing.

Abstract: An operating device (10) for an air vent (12) which includes at least one swiveling vane (14), the operating device (10) having a first operating lever (22) which has a first lever arm (30), a second lever arm (34), and a bearing member (38) which is arranged therebetween, the first operating lever (22) being mounted around the bearing member (38) for swiveling about a swivel pin (24), and a second operating lever (26) which has a first lever arm (32), a second lever arm (36), and a bearing member (40) which is arranged therebetween, the second operating lever (26) being mounted around the bearing member (40) for swiveling about a swivel pin (28), the first lever arm (32) of the second operating lever (26) being coupled to the second lever arm (34) of the first operating lever (22) and the second lever arm (36) of the second operating lever (26) being adapted to be coupled for swiveling motion to the vane (14).

Abstract: In the manufacturing of an operating element (10) for an air vent, a first partial element (12) is manufactured from a hard component in a first injection molding process and a second partial element (14) is manufactured from a soft component in a second injection molding process. The second partial element (14) forms a bearing (20) for a support of the operating element (10) on a vane (22) of the air vent. During its manufacture, the second partial element (14) is connected with the first partial element (12) by adhesion and/or by geometric shaping. The two partial elements (12, 14) that are captively connected with each other constitute a prefabricated unit.
