Acoustic protection structure for hood of motor vehicle, has flexible and porous sheet spaced apart from hood to create air gap between sheet and hood, where peripheral band of sheet is compressed to form rigid periphery for sheet

摘要

The structure (1) has a flexible and porous sheet (3) associated, in a tensioned condition, with a lower part of a hood (2) and spaced apart from the hood so as to create an air gap (4) between the sheet and the hood. A peripheral band (9) of the sheet is compressed so as to form rigid periphery for the sheet that is fixed at the hood by a pin (6), where the pin is inserted into an opening (7) formed in the band. The band is shaped in a profile to provide better bending resistance, where the gap between the sheet and the hood is about 5 to 50 mm.
