Disclosed is a floor covering insulation for a motor vehicle with a multi-layer, preferably flocked, fibre insulation which, by a soft/smooth coupling layer to the wear surface, realises a sound insulation floor covering with improved acoustic and mechanical-physical properties, with a simultaneous reduction in weight if possible. Also disclosed is a process for manufacturing the sound insulation.

A vehicle includes a metallic floor pan. A plurality of trim components defining a foot well is proximate the floor pan. A flooring component is coupled with the floor pan which includes a polymeric structural layer. An insulation layer is positioned on the structural layer. A sealing layer is coupled with the floor pan and extends to seal the insulation layer against the structural layer.

A motor vehicle soundproofing part includes a base body made from foam or felt and a surface layer, applied on the base body. The base body has shaping reliefs and the surface layer includes a plurality of through perforations and airtight regions between the perforations. Each perforation has a transverse dimension smaller than 1.5 mm, advantageously smaller than 1 mm and, in particular, between 0.1 mm and 0.5 mm.

A vehicle-body bottom portion comprises a noise-insulation inferior part and a noise-insulation superior part provided adjacently to a periphery of the noise-insulation inferior part. Between the vehicle-body bottom portion and a floor carpet are provided a sound-absorbing member which is arranged between the noise-insulation inferior part and the floor carpet, a cross member which connects the noise-insulation superior part and the floor carpet and seals a gap between the vehicle-body bottom portion and the floor carpet, and a noise insulation space which is adjacent to the sound-absorbing member and the cross member and enclosed by the sound-absorbing member and the cross member.

A sound insulation element for the wall of a vehicle body between the passenger compartment and the engine compartment has a front side facing the passenger compartment formed by the outer side of A plastic carrier layer, and a rear side which rests against the front wall formed by the outer side of a sound-absorbing layer. At least one holding-down projection projects from the plastic carrier layer at and/or offset from the edge of the hole of the carrier layer on the inner side of the plastic carrier layer facing away from the outer side of the plastic carrier layer facing the sound-absorbing layer, which is embedded in the sound-absorbing material of the sound-absorbing layer and whose free ends facing away from the plastic carrier layer are substantially aligned with the outer side of the sound-absorbing layer facing away from the plastic carrier layer.

A steering apparatus of a vehicle includes: a dust pack housing coupled to a top portion of a dust cap, which is combined with a rack housing to surround a pinion shaft, the dust pack housing disposed between and supporting a dash panel of the vehicle and the dust cap; and a noise attenuation member disposed between the dust pack housing and the pinion shaft and having plate shape so that an inner side of the noise attenuation member is spaced apart from the pinion shaft and an outer side of the noise attenuation member is fitted to the dust pack housing to attenuate noise that is transmitted to the inside of the dust panel.

The invention relates to an acoustic component contoured in a planar manner or three-dimensionally shaped, namely a firewall of a motor vehicle, and use of said component, said component comprising at least one sound-absorbing material and possibly at least one carrier material, wherein the sound-absorbing material is completely or partially covered by a flow layer at least on a planar side or in a composite of layers, wherein the flow layer has nanofibers.

In a vehicle floor structure, an insulator is arranged on a floor of a vehicle, and a floor carpet is arranged on the insulator. The vehicle floor structure includes an attachment member that fixes the insulator to a vehicle body side. The attachment member includes a fixation part that fixes the floor carpet.

An insulation module for a floor of a motor vehicle includes a panel of a molded and bound fiber material. The panel extends along a longitudinal axis (X). At least one notch is formed in the thickness direction (D) of the panel and extends at an angle between 0 and 30 to the longitudinal axis (X). At least one incision is formed in an outer edge of the panel and extends at an angle between 80 and 100 to the longitudinal axis (X) of the panel.

A front lid for a vehicle, especially a motor vehicle, which front lid includes an outer panel, where, in a predetermined region or in the entire area of the front lid below the outer panel, at least one inertia mass is arranged, and the inertia mass is formed of a flexible heavy layer.
