Operating element for an air vent

1. An operating element ( 10 ) for an air vent, comprising a narrow passage ( 14 ) from a first side ( 16 ) to an opposite second side ( 18 ) for a blade ( 12 ), the blade having a longitudinal direction and a transverse direction that define a plane, the passage extending through the operating element in the longitudinal direction of the blade, the passage ( 14 ) being limited on both sides by frame-shaped lateral portions ( 20 ) spaced from each other in the longitudinal direction of the blade, at least one of the frame-shaped lateral portions ( 20 ), at a rear side ( 28 ) of the operating element ( 10 ), fully extending across the blade ( 12 ) inserted in the passage ( 14 ) in a direction substantially perpendicular to the plane, at least one of the frame-shaped lateral portions ( 20 ) comprising a slit ( 24 ) so that at least a part ( 22 ) of the lateral portion ( 20 ) may be deflected elastically wherein the slit ( 24 ) in the frame-shaped lateral portion ( 20 ) extends transverse to the longitudinal direction of the blade and parallel to the blade's plane.

2. The operating element ( 10 ) for an air vent according to claim 1 , wherein the inner contour of the operating element ( 10 ) has a profile which is adapted to the outer contour of the blade ( 12 ) and comprises at least one protuberance or depression.

3. The operating element ( 10 ) for an air vent according to claim 2 , wherein the inner contour of the operating element ( 10 ) comprises a groove ( 30 ) or a wedge-shaped protrusion ( 32 ) along the passage ( 14 ) in passage direction.

4. The operating element ( 10 ) for an air vent according to claim 3 , wherein the groove ( 30 ) or the wedge-shaped protrusion ( 32 ) comprise opposing, inclined side walls ( 36 , 38 ) defining an inclination angle <90°.

5. The operating element ( 10 ) for an air vent according to claim 3 , wherein the groove ( 30 ) or the wedge-shaped protrusion ( 30 ) has a generally trapezoidal cross-section.

6. The operating element ( 10 ) for an air vent according to claim 1 , wherein the operating element ( 10 ) is made in one piece of plastics.

7. An assembly comprising a blade ( 12 ) and an operating element ( 10 ) for an air vent according to claim 1 , wherein the inner contour of the operating element ( 10 ) has a profile with at least one protuberance or depression and the outer contour of the blade ( 12 ) has a profile with a depression or protuberance adapted thereto, respectively, so that the protuberance projects into the depression.

8. The assembly according to claim 7 , wherein a wedge-shaped protrusion ( 32 ) extending along the passage ( 14 ) of the operating element ( 10 ) in passage direction engages a groove ( 30 ) extending along the blade ( 12 ) in the longitudinal direction of the blade, or a wedge-shaped protrusion ( 32 ) extending along the blade ( 12 ) in the longitudinal direction of the blade engages a groove ( 30 ) extending along the passage ( 14 ) of the operating element ( 10 ) in passage direction.

9. The assembly according to claim 7 , wherein the outer contour of the blade ( 12 ) is manufactured with oversize compared to the inner contour of the operating element ( 10 ) such that the blade ( 12 ) engages the operating element ( 10 ) to provide a friction force therebetween.

10. The assembly according to claim 7 , wherein the operating element is arranged on the blade ( 12 ) so as to be stationary in both directions transverse to the longitudinal direction of the blade and so as to be movable in a guided manner in the longitudinal direction of the blade.

11. An operating element for an air vent, comprising:

a passage extending in a first direction from a first side of the operating element to an opposite second side of the operating element for receiving a blade of the air vent, the blade having a longitudinal direction and a transverse direction that define a plane, the passage extending through the operating element in the longitudinal direction of the blade;

a first frame-shaped lateral portion on the first side having an upper portion engagable with an upper surface of the blade, a lower portion engagable with a lower surface of the blade, and a part extending from the upper portion to the lower portion at a rear side of the operating element in a direction substantially perpendicular to the plane; and

a second frame-shaped lateral portion on the opposite second side having a slit allowing elastic deflection of a part of the second frame-shaped lateral portion, the second frame-shaped lateral portion being spaced from the first frame-shaped lateral portion in the longitudinal direction of the blade.
