AIR VENT
Two parallel blades are disposed at a distance behind one another, in a flow direction, in an air vent for a motor vehicle, which are jointly pivoted in a manner opposite one another by way of a coupling device, and disposing, between the two blades, a louver comprising blades, which are disposed next to one another and can be jointly pivoted parallel to one another, perpendicularly to the two other blades.
1 . An air vent, comprising an air channel including an inflow opening and an outflow opening, comprising at least three blades, which are disposed behind one another in a flow direction through the air channel from the inflow opening to the outflow opening and can be pivoted for guiding an air current through the air channel, of which a first blade at the outflow opening which can be pivoted about a first pivot axis and a third blade at the inflow opening which can be pivoted about a third pivot axis are parallel to one another, and a second blade that can be pivoted about a second pivot axis is disposed between the first and third blades at an angle with respect to the first and third blades in the air channel, and comprising a coupling device, which couples the first blade to the third blade such that the first blade can be pivoted in a manner opposite that of the third blade, wherein the third pivot axis of the third blade is disposed, in the flow direction through the air channel, between a center of the third blade and an edge of the third blade which faces the second blade, and that the first and third pivot axes are stationary with respect to the air channel.
2 . The air vent according to claim 1 , wherein the second pivot axis of the second blade, in the flow direction through the air channel, is disposed at a center of the second blade and/or a first pivot axis of the first blade, in the flow direction through the air channel, is disposed between a center of the first blade and an edge of the first blade which is remote from the first and second blades.
3 . The air vent according to claim 1 , wherein the second pivot axis of the second blade is stationary with respect to the air channel.
4 . The air vent according to claim 1 , wherein the first and third blades are distanced from one another in the flow direction through the air channel, and that the second blade extends through an intermediate space between the first and third blades formed by the distance.
5 . The air vent according to claim 1 , wherein the first and third blades are coupled to a coupling rod, which is connected to the first and third blades in an articulated manner, and in each case at a radial distance with respect to the first and third pivot axes.
6 . The air vent according to claim 1 , wherein a plurality of second blades are disposed next to one another between the first and third blades in the flow direction through the air channel and so as to be jointly pivotable, the second blades being pivotable into a blocking position in which these close the air channel.
7 . The air vent according to claim 1 , wherein an operating element is disposed at the first blade, which is non-rotatable with respect to the first blade and displaceable parallel to the first pivot axis.
8 . The air vent according to claim 1 , wherein the operating element is operatively connected to the second blade by way of a connector, and that the connector is mounted at the first blade so as to be rotatable about the first pivot axis.
9 . The air vent according to claim 8 , wherein the connector engages on an end face of the second blade which faces a channel wall of the air channel of the air vent.
