Grazing unit with improved vibration sound attenuation characteristics, method of manufacturing such a glazing unit, and soundproofing method in a vehicle passenger compartment

摘要

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.
