ABSTRACT:
A screening element for motor vehicles is disclosed with a lead-in element which provides a preferred heat, sound and vibration uncoupling in the body region. The screening element supplied in this case comprises at least two separated outer layers between which an insert is arranged, wherein the at least two separated outer layers and the insert have coaxial openings which form a common opening in which a lead-in element is received or mounted, wherein the openings of the respective outer layers have a larger cross-sectional area than the opening of the insert, where the lead-in element is connected to the insert in such a manner that there is no contact with the outer layers. The screening element or heat shield therefore has a sufficient heat, sound and vibration uncoupling, can be produced at low cost without manual operations, and is simple to assemble. Moreover, a heat and vibration transmission of hot components from the engine compartment or underfloor to the body is prevented at the fastening points of the screening element.
