Abstract: The invention relates to an acoustically effective wheel house covering for vehicles, i.e. a wheel house covering which can reduce transmission of splash water noises in the passenger compartment of the vehicle and which can absorb the sound of rolling tires on a roadway, which wheel house covering comprises several layers of material.

Abstract: The invention relates to a soundproof thermal shield (3), particularly for motor vehicles, comprising an aluminum support (4), a noise-absorbing layer (6) and an aluminum thermal covering (7). In order to make the inventive soundproof thermal shield easy to recycle while obtaining a great thermal shielding effect and noise-absorbing power, a permeable mat made of knitted aluminum is used as a noise-absorbing layer (6), said knitted aluminum being superimposed in several layers and pressed so as to form the permeable mat. The inventive thermal shield is thus made of a single material. Preferably, the support (4) is made of a microperforated aluminum sheet while the thermal covering (7) is preferably made from an aluminum film.

Abstract: A sound absorber (A), especially for motor vehicles, comprising a layer (4) of absorption material, such as open-pored or optionally closed pored foamed material or a wood fiber composite, and a top layer (5) . The aim of the invention is to produce an absorber in such a way that said absorber is easy to produce and assemble and functions well. According to the invention, the top layer (5) for leading through a loom of cables (8) or the like is provided with a tubular recess (40) for leading through a loom of cables. Said recess (4) is provided with groove-like undercuts (42) on the outside.

Abstract: Motor-vehicle door (1) comprising an outer wall (2) and an inner wall (3), a cladding part (4) mounted on the inner wall (3), and an insulation element (5) disposed between the inner wall (3) and the cladding part (4), the insulation element (5) being formed as a foam layer and being clamped in at its edge between the cladding part (4) and the inner wall (3) in a clamping region (K), wherein the insulation element (5) is secured in an adhesive-free manner between the cladding part (4) and the inner wall (3) in the clamping region (K), forming a positively locking profiling.
