Abstract

An air guiding element, in particular a cooling air louver for an air inlet of a motor vehicle body, with a flat main body and with a bearing region. The air guiding element is arranged such that it can be pivoted by way of its bearing region about a pivot axis. The flat main body is formed from two shells, and with a carrier element which is arranged between the shells. The carrier element is molded between the two shells by an injection molding method such that the two shells are connected to one another in this way.

First claim

What is claimed:

1. An air guiding element for an air inlet of a motor vehicle body, said air guiding element comprising:
a flat main body having a bearing region, the air guiding element being configured to pivot on the bearing region about a pivot axis, the flat main body including two shells that are connected to one another and a carrier element which is both arranged and molded between the shells.

2. The air guiding element as claimed in claim 1 , wherein the air guiding element is produced by an assembly injection molding process or a hollow chamber injection molding process.

3. The air guiding element as claimed in claim 1 , wherein the bearing region is part of at least one of the two shells, or is configured in one piece with at least one of the two shells.

4. The air guiding element as claimed in claim 1 , wherein the carrier element is configured between the two shells as a substantially rectangular frame.

5. The air guiding element as claimed in claim 1 , wherein the carrier element is configured between the two shells as a substantially rectangular frame with two first limbs which lie opposite one another and with two second limbs which lie opposite one another.

6. The air guiding element as claimed in claim 1 further comprising a gate of the carrier element.

7. The air guiding element as claimed in claim 6 , wherein the gate comprises a receptacle for a push rod, a bearing bush and/or a gearwheel.

8. The air guiding element as claimed in claim 1 , wherein the two shells comprise a first plastic material.

9. The air guiding element as claimed in claim 8 , wherein the carrier element comprises a second plastic material that differs from the first plastic material.

10. The air guiding element as claimed in claim 9 , wherein the first plastic material is polypropylene PP-T20 and the second plastic material is polypropylene PP-GF30.

11. A method for producing an air guiding element including a flat main body having a bearing region, the air guiding element being configured to pivot on the bearing region about a pivot axis, the flat main body including two shells that are connected to one another and a carrier element arranged between the shells, said method comprising:
injection molding the two shells;
following the injection molding step, joining together the two shells together leaving a cavity therebetween; and
following the joining step, injecting the carrier element between the two shells in either an assembly injection molding method or a hollow chamber injection molding method.
