INSULATING AND SOUND DAMPING ELEMENT

The invention relates to an insulating element (1) which can be arranged in a cavity (6) provided by an outer wall (4) and an inner wall (3) of a motor vehicle door (2) for the purpose of sound insulation or sound damping, and preferably moisture barrier, on a foamed material basis, having a wall th...

Beschreibung
Zusammenfassung:	The invention relates to an insulating element (1) which can be arranged in a cavity (6) provided by an outer wall (4) and an inner wall (3) of a motor vehicle door (2) for the purpose of sound insulation or sound damping, and preferably moisture barrier, on a foamed material basis, having a wall thickness which is continuously approximately the same and is thin in relation to the space between the inner faces of the outer wall (4) and the inner wall (3), the insulating element (1) being profiled. In this context, it is proposed that in order to achieve a simple but effective construction, a bead (7) which is formed in particular at the edges, is essentially U-shaped in cross-section and leads to a support of the single-layer insulating element on both inner faces of the outer wall and inner wall is provided, a freely vibratable section (13) of the insulating element (1) extending between two such bead formations (7, 8 etc.) which are supported on both inner faces.
