Abstract

An air distribution duct configured to be connected to a heating and/or air-conditioning device of a motor vehicle, the air distribution duct including: a connection end configured to be connected to the heating and/or air conditioning device; a closed other end; a longilinear main branch with one end which forms the closed end and the other end which forms the connection end, one face of the main branch being pierced with one or a number of orifices; at least one other orifice situated on a secondary branch one end of which is connected to the main branch and the free other end of which is closed, the at least one other orifice being on a face situated on a same side of the duct as the other orifices of the main branch.

Claims

1-10. -10. (canceled)

11. An air distribution duct configured to be connected to a heating and/or air-conditioning device of a motor vehicle, the air distribution duct comprising:

a connection end configured to be connected to the heating and/or air-conditioning device;

a closed end;

a longilinear main branch with one end which forms the closed end and an other end which forms the connection end, one face of the main branch being pierced with one or more orifices;

at least one other orifice located on a secondary branch with one end connected to the main branch and the free other end closed, the at least one other orifice being on a face located on a same side of the duct as the one or more orifices of the main branch.

12. The air distribution duct as claimed in claim 11, wherein a single other orifice is located on the secondary branch.

13. The air distribution duct as claimed in claim 12, wherein the secondary branch is as long as the single other orifice.

14. The air distribution duct as claimed in claim 11, wherein the secondary branch extends along the main branch.

15. The air distribution duct as claimed in claim 11, wherein the secondary branch is rigidly connected to the main branch along an entire length of the main branch.

16. The air distribution duct as claimed in claim 11, comprising at least three orifices, at least two orifices pierced in the main branch and a single orifice pierced in the secondary branch.

17. The air distribution duct as claimed in claim 11, wherein the secondary branch is connected to the main branch between the one or more orifices of the main branch and the connection end.

18. The air distribution duct as claimed in claim 11, wherein the orifices pierced in the main and secondary branches open out on a same plane.

19. A motor vehicle comprising a heating and/or air-conditioning device for the passenger compartment and at least one air distribution duct as claimed in claim 11 connected to the heating and/or air-conditioning device and in which the orifices open into inside of the passenger compartment, above a floor of the vehicle.

20. The motor vehicle as claimed in claim 19, wherein the main branch of the at least one air distribution duct extends substantially transversally inside the vehicle.
