Embodiment Construction

[0024] Figure 1 shows a cross member 1 that reinforces the structure of a vehicle. This cross member 1 is incorporated into the interior of the vehicle dashboard and supports some structural parts, such as a speedometer or an air conditioner.

[0025] For example, this cross member 1 is located near the lower edge of the windshield inside the dashboard. It has a hollow closed cross-section (Figure 3) and is made of rigid material, usually metal.

[0026] The distribution pipe 2 is made of plastic by extrusion. It is essentially a parallelepiped in shape and includes two openings 4 and 5 on each side of the pipe. The first opening 4 is used to receive air from the air conditioner to pass the air to the second opening 5 through the duct 2. This second opening communicates with the vehicle cabin in a conventional manner, so that air that may be hot or cold is introduced into it.

[0027] As shown in FIG. 2, the air distribution duct 2 is inserted into the cross member 1. The cross-me...

Abstract

The invention relates to an air distribution duct (2) integrated in the passenger compartment of a motor vehicle comprising at least one rigid hollow crossmember (1) that reinforces the structure of the vehicle, characterized in that the duct (2) is made by extrusion and is placed in the crossmember (1) at a distance from the inside wall of the crossmember.

Description

Technical field [0001] The present invention relates to an air distribution duct for distributing air in the cabin of a motor vehicle, and in particular to such a device connected to an air conditioning unit, which allows air, which may be hot or cold, to be delivered to different positions in the cabin . Background technique [0002] With the continuous reduction of noise damage generated by motor vehicle engines, the air conditioner constitutes an important noise source, and the air distribution device plays a role in this. Due to the transparency of the air duct of the device, the noise of the fan spreads directly into the cabin. In addition, these pipes themselves are sources of noise, which are caused by eddy currents generated by their structure. [0003] The known air distribution device, which is usually arranged in the dashboard of the vehicle, also has the disadvantage of occupying a considerable amount of space, and it is difficult to control when designing the vehicle...
