Benefits of technology

[0011]It is an object of the invention to provide a sound-damping air-conducting duct that can be produced in more cost-advantageous manner, while providing advantageous possibilities for further improved noise reduction, and in which detachments of the sound-absorbing lining are avoided or prevented.

Problems solved by technology

Such production is complicated and expensive.
In addition, detachments of the lining can occur, which can then get into the space to be ventilated or air-conditioned, and consequently into the air that is being breathed in, so that they represent a hazard for life and health.

Embodiment Construction

[0042]Referring now in detail to the drawings, the air-conducting duct 20 shown schematically in longitudinal cross-section in FIG. 1 is configured in tubular shape and has an entry opening 21 for air and an exit opening 22 for the air that flows through air-conducting duct 20 in the direction of the arrow 51. Entry opening 21 can stand in a flow connection with an air transport device, not shown in the figures, for example with a fan and / or with an air-conditioning system for conditioning the air. The air to be conveyed in air-conducting duct 20 in direction 51, if applicable air-conditioned air, can be transferred to a space or chamber 50 to be ventilated or to be air-conditioned, out of exit opening 22. In a region ahead of exit opening 22, air-conducting duct 20 widens up to exit opening 22, so that the cross-sectional shape changes in this duct segment region, in the longitudinal direction of air-conducting duct 20; here, it widens crosswise or perpendicular to direction 51.

Abstract

A sound-damping air-conducting duct that has at least one exit opening for air, and is provided, in the region of the exit opening, with a lining made of a sound-absorbing material, which lining is surrounded, at least on its outside, by a wall made of plastic, provided with holes, and the lining is attached to this wall, whereby the lining is immediately, preferably directly, connected with the wall, with material fit and / or shape fit, and / or is connected with it in a single work step with the wall that is produced using a primary shaping method. A method for the production of a sound-absorbing air-conducting duct is also provided.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]Applicants claim priority under 35 U.S.C. §119 of German Application No. 10 2007 060 525.2 filed Dec. 13, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a sound-damping air-conducting duct or to an air-conducting duct for air conditioning and / or ventilation systems, particularly for vehicles or in a vehicle, preferably for motor vehicles or in a motor vehicle. The duct has at least one exit opening for air, and is provided, in the region of the exit opening or in the exit region, preferably by way of a longitudinal segment, with an at least partially air-permeable or sound-permeable lining made of a material that absorbs or damps sound carried in the air, which lining is surrounded, at least on its outside, by a wall made of plastic, provided with holes at least in the region of the lining, preferably forming a self-supporting line segment, and the lining is attached to this wall.[000...
