Sound-proofing panel for motor vehicle, has injected elastomer material layer formed with organ traversing orifice that traverses organ, where elastomer material layer forms rim made of expanded material in periphery of orifice

摘要

The panel (1) has an injected elastomer material layer (2) formed with an organ traversing orifice (3) that traverses an organ. The elastomer material layer forms a rim (4) made of expanded material in a periphery of the orifice. The elastomer material layer receives a sub layer (5) made of elastic layer to form a block spring type sound-proofing system. The rim is extended in projection with respect to a right side surface of the elastomer material layer. The elastomer material is selected from ethylene propylene diene monomer (EPDM) or ethylene-vinyl acetate (EVA). An independent claim is also included for a method for manufacturing a sound-proofing panel.
