Embodiment Construction

[0048] The invention relates to a glazing with improved vibro-acoustic attenuation properties, the glazing comprising at least one pane of glass and at least one vibro-acoustic attenuating profile comprising at least one element of attenuating material. Thus, the glazing allows noise attenuation.

[0049] The profile is fixed on one surface of the glass sheet. The surface of the profile facing the glass sheet has an area in contact with the glass sheet that is strictly smaller than the area of ​​the surface of the profile facing the glass sheet.

[0050]Thus, a part of the profile is not fixed to the glass sheet and is outside the surface of the glass sheet. This part of the profile therefore protrudes beyond the edge of the pane. As a result, the profile occupies only a small amount of space on the pane of glass. Even when the glazing is in the closed position, the entire profile can easily be arranged under the weather seal (joint lécheur) of the vehicle glazing frame.

Abstract

A glazing unit having improved vibroacoustic damping properties, including: at least one glass sheet; at least one vibroacoustic damping strip, the strip including at least one element made of damping material and the strip being fastened to one of the faces of the glass sheet. The face of the strip facing the glass sheet has a surface area in contact with the glass sheet which is strictly inferior to the surface area of the face of the strip facing the glass sheet. The glazing unit makes it possible to damp noise and vibrations while taking up little space.

Description

technical field [0001] The present invention relates to a glazing with improved vibro-acoustic attenuation properties, the glazing comprising a vibro-acoustic attenuating device, the invention also relates to a method for attenuating sound and method of vibration disturbance. Background technique [0002] In addition to motor vehicles or other types of vehicles (e.g. trucks, passenger cars, agricultural equipment), the invention is also applicable to all types of motorized equipment (e.g. airplanes, trains, ships, submarines) having a closed or substantially closed cabin Wait). [0003] Glazing associated with vehicles, especially motor vehicles, often includes vibroacoustic attenuation devices for attenuating vibration waves propagating through the glazing in order to improve the acoustic comfort of the vehicle interior. [0004] In motor vehicles, sources of annoyance from mechanical, thermal, visibility, etc. have increasingly been brought under control. However, impro...
