Air-diffusion panel for a motor vehicle including at least one air inlet and at least one air duct in communication with the said air inlet and air-distribution means, characterised in that it includes at least one resonant cavity ( ) tuned so as at least partially to reduce the airstream noise in the said duct ( ).

Air-diffusion panel for a motor vehicle

The invention concerns an air conduit for motor vehicle instrument panel made in the form of an open conduit with a longitudinal slot defined by two fusion faces, the open conduit being produced in one single piece with the instrument panel by moulding a ductile material enabling the stripping by widening the longitudinal slot, means for joint being provided by joining the fusion faces of the longitudinal slop after stripping.

Integrated air conduit for motor vehicle instrument panel

Method for making a motor vehicle dashboard with built-in air ducts, and

A motor vehicle dashboard has a support face. Air ducts are carried by the dashboard for taking air into the cabin of the vehicle. Each duct has a longitudinal slot which is bounded by two adjacent edges, so that the duct has a transverse cross section in the form of an open annulus. The duct has two external engagement faces on either side of the longitudinal slot, and is fixed to the support face of the dashboard by means of these engagement faces. The duct is made by moulding in a suitable deformable material such that it can be stripped from the mould by opening out the slot, after which the slot is closed up again.
