Abstract
An air vent for a motor vehicle with two air control elements that are disposed inside one another, the outer air control element of which is tubular in such a way that the air control elements delimit a first air channel between one another, and the outer air control element delimits a second air channel between itself and a tubular housing of the air vent. For restricting an air current flowing through the air vent, the two air control elements can be displaced by way of two helical gears coaxially in the housing, which are disposed coaxially inside one another and in the housing and which include a tube including an internal thread and an external thread, serving as a shared drive element, which forms a spindle nut for an interior, and a (hollow) spindle for an exterior, of the two helical gears.
Claims9
An air vent comprising a first air control element, wherein the air vent comprises a first helical gear having an axis of rotation and a first sliding guide for the first air control element which is parallel to the axis of rotation of the first helical gear, and that, when the first helical gear is rotatably driven, the first helical gear displaces the first air control element along the first sliding guide.
