Abstract

An air vent comprising a housing extending between an air inlet opening and an air outlet opening, such that the housing has a first wall segment and a second wall segment; an air guiding element, arranged at least partially inside the housing thereby creating a first partial airflow channel and a second partial airflow channel between the air inlet opening and the air outlet opening; an airflow regulating element for regulating the airflow through the partial air flow channels, which airflow regulating element is arranged at the side of the air guiding element that is facing the air inlet opening; wherein the airflow regulating element forms an extension of the air guiding element in the direction of the air inlet opening and wherein the airflow regulating element is pivotable around an axis that lies behind the center of the airflow regulating element when viewed in the direction from the air outlet opening to the air inlet opening.

First claim

What is claimed is:

1 . An air vent comprising:
a housing extending between an air inlet opening and an air outlet opening, the housing including a first wall segment and a second wall segment; an air guiding element located at least partially inside the housing configured to create a first partial airflow channel and a second partial airflow channel between the air inlet opening and the air outlet opening; an airflow regulating element configured to regulate the airflow through the first partial air flow channel and the second partial airflow channel, the airflow regulating element being located at a side of the air guiding element that that faces the air inlet opening; the airflow regulating element configured to form an extension of the air guiding element in the direction of the air inlet opening, the airflow regulating element being pivotable around an axis located behind the center of the airflow regulating element when viewed from the air outlet opening toward the air inlet opening.

2 . The air vent of claim 1 , wherein the airflow regulating element is tapered from a second end portion to a first end portion.

3 . The air vent of claim 1 wherein the first partial airflow channel and the second partial airflow channel are curved towards each other in a vertical plane at the air outlet opening such that an air outlet flow direction of the first channel and an air outlet flow direction of the second channel cross each other.

4 . The air vent of claim 1 , wherein the airflow regulating element is wedge-shaped.

5 . The air vent of claim 1 , wherein the airflow regulating element comprises a cylindrical segment.

6 . The air vent of claim 1 wherein the first partial airflow channel comprises a lamella to direct a partial airflow in a horizontal direction.

7 . The air vent of claim 1 , wherein the airflow regulating element is pivotable in an upward direction for directing a net airflow upward and wherein the airflow regulating element is pivotable in a downward direction for directing the net airflow downward.

8 . The air vent of claim 1 , wherein the first partial airflow channel is configured to be closed when the airflow regulating element is abutting the first wall segment, and wherein the second partial air flow channel is configured to be closed when the airflow regulating element is abutting the second wall segment.

9 . The air vent of claim 1 , wherein the air vent is included as an interior trim part of a vehicle.

10 . The air vent of claim 6 , wherein the air guiding element is configured to direct an outlet airflow in a vehicle interior by pivoting the airflow regulating element upwards or downwards and moving the lamella such that the outlet airflow is directed leftwards or rightwards.

11 . The air vent of claim 1 , wherein, in a neutral position, the airflow regulating element is pivoted towards the air guiding element.

12 . The air vent of claim 1 , wherein, in a neutral position, the airflow regulating element comprises a tapering section arranged between the axis and a side of the airflow regulating element that faces the air outlet opening such that an area of a cross section of the airflow regulating element perpendicular to a direction of the airflow varies along the tapering section from the air outlet opening toward the air inlet opening.

13 . The air vent of claim 12 , wherein, in the neutral position, the tapering section extends over at least 10 percent of a length of the airflow regulating element between the axis and the side of the airflow regulating element that faces the air outlet opening.

14 . The air vent of claim 12 , wherein, in the neutral position, the tapering section extends over at least 25 percent of a length of the airflow regulating element between the axis and the side of the airflow regulating element that faces the air outlet opening.

15 . The air vent of claim 12 , wherein, in the neutral position, the tapering section extends over at least 50 percent of a length of the airflow regulating element between the axis and the side of the airflow regulating element that faces the air outlet opening.

16 . The air vent of claim 12 , wherein, in the neutral position, the area of the cross section of the airflow regulating element varies by at least 10 percent along the tapering section in the direction from the air outlet opening to the air inlet opening.

17 . The air vent of claim 12 , wherein, in the neutral position, the area of the cross section of the airflow regulating element varies by at least 25 percent along the tapering section in the direction from the air outlet opening to the air inlet opening.

18 . The air vent of claim 12 , wherein, in the neutral position, the area of the cross section of the airflow regulating element varies by at least 50 percent along the tapering section in the direction from the air outlet opening to the air inlet opening.

19 . The air vent of claim 12 , wherein, in the neutral position, wherein the tapering includes, a first portion located a first distance from the axis and a second portion located a second distance from the side of the airflow regulating element that faces the air outlet opening, wherein the cross section of the airflow regulating element perpendicular to the direction of the airflow increases along the first portion of the tapering section and decreases along the second portion of the tapering section from the air outlet opening toward the air inlet opening.
