The invention relates to a crush-resistant acoustically effective floor covering for a motor vehicle, in particular a commercial vehicle, comprising a decorative layer ( 2 ) and a crush-resistant blow moulded part ( 3 ) arranged underneath the decorative layer. In order to ensure an impeccable appearance of such a floor covering and in order to attain improved acoustic effectiveness while ensuring optimum crush-resistance, it is proposed that, on the top, the blow moulded part ( 3 ) comprise an essentially closed cover plate ( 5 ) while on the bottom it comprise a structural component ( 6 ), wherein the cover plate ( 5 ) and the structural component ( 6 ) have different wall thicknesses (d 1 , d 2 ). The structural component ( 6 ) comprises a plurality of box-shaped or cup-shaped hollow chambers ( 7 ) which are open on one side but closed on the underside, wherein at least some of the hollow chambers ( 7 ) which are closed off to the outside form part of a common air space enclosed between the cover plate ( 5 ) and the structural component ( 6 ). Furthermore, the structural component ( 6 ) is underfoamed with foam material ( 4 ). |
