Sound absorbing product having an integrated energy absorber and production method thereof

The panel is formed by a support membrane (3) to whose inner surface is attached a body of rigid cellular material (1) forming an energy-absorbent mass. The apertures of the cellular material are closed and partially filled by a block of relatively open foam material (7). The foam block extends beyo...

Beschreibung
Zusammenfassung:	The panel is formed by a support membrane (3) to whose inner surface is attached a body of rigid cellular material (1) forming an energy-absorbent mass. The apertures of the cellular material are closed and partially filled by a block of relatively open foam material (7). The foam block extends beyond the edges of the cellular material to enclose it completely, and traps pockets of air or another gas within the apertures of the cellular material. The foam is injection-moulded onto the cellular material to form a continuous smooth surface on the face of the panel opposite to the support membrane. Produit de garniture d'habitacles de véhicules présentant à la fois des propriétés insonorisantes et d'absorption d'énergie, caractérisé en ce qu'il est constitué par un septum (3) contre la face duquel est appliqué un matériau alvéolaire rigide (1) servant d'absorbeur d'énergie, dont les alvéoles sont garnies partiellement ou totalement d'une mousse (7) à pores ouverts en ménageant une couche continue de ladite mousse dépassant les lèvres dudit matériau alvéolaire.
