Embodiment Construction

[0022] Figure 1 shows a cross member 1 for reinforcing a vehicle structure. This cross member 1 is incorporated into the interior of the dashboard of the vehicle and supports structural elements such as the speedometer or the air conditioning body.

[0023] For example, this cross member 1 is located near the lower edge of the windshield inside the instrument panel. It has a hollow closed section (Fig. 3) and is made of a rigid material, usually metal.

[0024] The distribution line 2 is produced from plastic by extrusion. It is substantially parallelepiped in shape and comprises two openings 4 and 5 on each side of the duct. The first opening 4 is used to receive air from the air-conditioning body to pass the air to the second opening 5 via the duct 2 . This second opening communicates with the vehicle cabin in a conventional manner, so that air, which may be hot or cold, is introduced into it.

[0025] As shown in FIG. 2 , the air distribution duct 2 is inserted into the...

Abstract

The invention relates to an air circulation device for a motor vehicle passenger compartment comprising at least one rigid hollow cross member (1) for reinforcing the vehicle structure and an air distribution duct (2), wherein said device is characterised in that said cross member (1) is provided with a hollow section (1a) and a tubular section (1b) which are interconnected by a connecting piece (1c) fitting the shapes of the parts (1a, 1b) of the cross member (1) and assuring the rigidity of said assembly.

Description

technical field [0001] The present invention relates to an air distribution device 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 locations in the cabin . Background technique [0002] With the ever-increasing reduction of noise impairments produced by motor vehicle engines, air conditioning components are an important source of noise, for which air distribution devices play a role. Thanks to the transparency of the unit's air ducts, the noise of the fans travels straight into the cabin. In addition, these pipes are themselves a source of noise due to the eddy currents created by their structure. [0003] Known air distribution devices, which are usually arranged in the dashboard of a vehicle, also have the disadvantage of taking up a considerable amount of space, which is difficult to manage when designing the vehicle. ...
