Brief description of the thermal and acoustic protection of a wall of the structure of a motor vehicle

摘要

The present invention relates to a process for thermal and acoustic protection of a wall (10) of the structure of a motor vehicle, said method comprising the following steps: a carrying structure (2) is of press-formed metal plate, placed on said structure, at least a first format (4) of the porous layer of absorption, the cover with a second format (5) of the porous layer, so as to form a patch (6) comprising the superposed sheets; form a panel (1) by maintaining the said patch on the said structure by placing at least one fixing means (7) made of thermoplastic material in one piece in the form of a rod (8), the ends of said rod being provided with rods (9) perpendicular to said rod and extending on either side of the axis of said rod, said rod passing through said formats and an orifice (3) made in said structure and the said rods, ensuring the holding of said rod, to mount the panel (1) against the wall (10) of the structure of a motor vehicle, so that the patch is compressed against said wall.
