Abstract

A ventilation device includes at least one aerator having a channel capable of conveying an air flow from an inlet opening to an outlet opening, a hollow air guiding core housed in the channel and defining two air guiding surfaces delimiting, with this channel, two flow paths capable of transporting, respectively, to the outlet opening, first and second quantities of air from the inlet opening, a fin mounted so as to be able to pivot upstream from the core and arranged so as to make it possible to adjust the ratio between the first and second quantities of air, depending on the position of same, and a control module incorporated at least partially into the core of at least the aerator and having a control panel constituted at least partially by a downstream end wall of the core and being provided with a control device.

First claim

The invention claimed is:

1. An aeration device for the heating, ventilation and air conditioning system for a motor vehicle, including at least one aerator, comprising:
a channel capable of conveying an air flow from an inlet opening to an outlet opening emerging in an enclosure;
a hollow air guiding core housed in said channel and defining two air guiding surfaces opposite one another, said two guiding surfaces and said channel thus delimiting two flow paths capable of transporting, respectively, to said outlet opening, first and second quantities of air coming from said inlet opening; and
a first fin pivotably mounted upstream from said guiding core and arranged so as to make it possible to adjust, as a function of its position, the ratio between the first and second quantities of air,
wherein said aeration device includes a control module integrated at least partially into the guiding core of said at least one aerator,
said control module comprising a control panel constituted at least partially by a downstream end wall of said guiding core and equipped with a control device making it possible to control the heating, ventilation and air conditioning system.

2. The aeration device according to claim 1 , wherein said control device includes at least one pushbutton and an adjusting ring mounted for rotating around said pushbutton.

3. The aeration device according to claim 1 , wherein said control device includes at least one movable knob.

4. The aeration device according to claim 1 , wherein said control device includes at least one touch-sensitive zone control device.

5. The aeration device according to claim 1 , wherein said control panel includes at least one display zone provided with one or more lighted indicators each displaying a value of an adjustment parameter of said heating, ventilation and air conditioning system.

6. The aeration device according to claim 1 , wherein said control module includes other control devices making it possible to control other functional devices of said vehicle.

7. The aeration device according to claim 1 , wherein said at least one aerator includes a row of second parallel deflector fins pivotably mounted in said channel along axes of rotation perpendicular to an axis of rotation of said first fin and secured in rotation via a connector connecting them to one another.

8. The aeration device according to claim 1 , wherein said at least one aerator includes two aerators arranged side by side and separated by a partition and intended to diffuse air in the passenger compartment of the motor vehicle, respectively on the driver's side and on the front passenger's side.

9. The aeration device according to claim 8 , wherein said panel extends continuously between the two aerators.

10. A motor vehicle, wherein the motor vehicle includes the aeration device according to claim 1 .

11. An aeration device for the heating, ventilation and air conditioning system for a motor vehicle, the aeration device including two aerators, each aerator comprising:
a channel capable of conveying an air flow from an inlet opening to an outlet opening emerging in an enclosure;
a hollow air guiding core housed in said channel and defining two air guiding surfaces opposite one another, said two guiding surfaces and said channel thus delimiting two flow paths capable of transporting, respectively, to said outlet opening, first and second quantities of air coming from said inlet opening; and
a first fin pivotably mounted upstream from said guiding core and arranged so as to make it possible to adjust, as a function of its position, the ratio between the first and second quantities of air,
wherein said aeration device further includes a control module integrated at least partially into the guiding core at least one of said aerators,
said control module comprising a control panel equipped with a control device making it possible to control the heating, ventilation and air conditioning system,
wherein said two aerators are arranged side by side and separated by a partition to diffuse air in the passenger compartment of the motor vehicle, respectively on the driver's side and on the front passenger's side,
wherein said panel extends continuously between the two aerators and is formed by three downstream end walls, including end walls of the two hollow guiding cores and of a central connecting element.

12. An aeration device for the heating, ventilation and air conditioning system for a motor vehicle, including at least one aerator, comprising:
a channel capable of conveying an air flow from an inlet opening to an outlet opening emerging in an enclosure;
a hollow air guiding core housed in said channel and defining two air guiding surfaces opposite one another, said two guiding surfaces and said channel thus delimiting two flow paths capable of transporting, respectively, to said outlet opening, first and second quantities of air coming from said inlet opening; and
a first fin pivotably mounted upstream from said guiding core and arranged so as to make it possible to adjust, as a function of its position, the ratio between the first and second quantities of air,
wherein said aeration device includes a control module integrated at least partially into the guiding core of said at least one aerator,
said control module comprising a control panel constituted at least partially by a downstream end wall of said guiding core and equipped with a control device making it possible to control the heating, ventilation and air conditioning system,
wherein each aerator further includes a respective concealing flap pivotably mounted upstream from the first fin.
