A low-melting adhesive film may include a first adhesive layer made of a material comprising thermoplastic polyurethane, a second adhesive layer made of a material comprising aromatic-based hot-melt thermoplastic polyurethane capable of being applied to low temperature adhesion at a temperature of 60 C. or higher, and a polyethylene (PE)-based protective film layer. The low-melting adhesive film may be used to adhere a carpet fabric to a sound absorbing material and thus produce an integrated sound absorbing and proofing composite carpet.

A noise attenuating trim part for a vehicle, with acoustic mass-spring characteristics comprising a mass layer comprising at least an impervious barrier layer, and a decoupling layer consisting of open cell foam and wherein the decoupling layer has a first surface adjacent to the mass layer and a second surface facing away from the mass layer, and wherein the decoupling layer and mass layer are laminated together and wherein the decoupling layer has at least one region with a plurality of indentations wherein each indentation comprises a round base area wherein the round base areas are situated in plane with the second surface and wherein the total surface area of the round base areas is between 10 and 40% of the total surface area of the second surface of the decoupling layer.

A vehicle is provided that includes a dash panel that partitions a power unit room, arranged on a vehicle front side and a vehicle interior from each other, an instrument panel that covers the dash panel from a vehicle rear side and at a portion of which, on a driving seat side and a vehicle lower side an opening section through which an arm section of a pedal is insertable is formed, and a sound insulating section that is installed along a surface on the vehicle rear side of the dash panel, in which the sound insulating section includes a driving seat side sound insulating section that is configured including a driving seat side sound absorbing material that is arranged along a portion on the driving seat side of the dash panel and is made of an elastically deformable material and a high density material that is arranged along and closely attached to a surface on the vehicle rear side of the driving seat side sound absorbing material and is made of a material that has a higher density than the material of the driving seat side sound absorbing material, and a front passenger seat side sound insulating section that is configured with one or more sound absorbing materials that are arranged along a portion on a front passenger seat side of the dash panel, in which a number of sheets of the sound absorbing materials arranged in a plate thickness direction of the dash panel is set at a number less than or equal to a number of sheets of sound absorbing materials included in the driving seat side sound insulating section.

A vehicle body floor structure includes: a plurality of first vehicle body framework members extending along a vehicle body front-rear direction; a plurality of second vehicle body framework members extending along a vehicle width direction; a floor panel to which each of the first vehicle body framework members and the second vehicle body framework members is joined; and a vibration damping material that is applied to a surface of the floor panel. The floor panel includes a plurality of steps having ridge lines extending along a short-side direction of a first region. The first region is surrounded by the first vehicle body framework members and the second vehicle body framework members. The vibration damping material is applied along at least one outer edge portion of the first region.

A one-step process for the production of a paneling is provided and, in particular, floor paneling for a motor vehicle with an insulation of fiber/absorbent nonwoven, as well as possibly further absorbent layers, which can differ zonally (partially) over the area and thickness of the insulation in their mechanical-physical and acoustic properties. The focus are nonwoven structures whose fiber orientation is perpendicular to the surface/wear layer of the floor paneling.

One or more techniques and/or systems are disclosed for a new coolant tank that may also provide a structural element to the frame of the engine compartment. The coolant tank is comprised of a rear wall that also makes up a portion of the firewall in the engine compartment. A structural coolant tank component is engaged with the rear wall to form the coolant reservoir. The coolant reservoir can provide support to attach structural elements of the vehicle, and can also allow for improved space efficiency in the engine compartment. Further, improved access to the filling port is provided, while continued operation and desired function is maintained even at extreme vehicle tilt.

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 soundproof body is formed by a two-layer lamination structure of a felt layer and a film layer. Some of plural fibers constructing the felt layer are formed to be thicker than the remaining fibers.

A snow groomer; the snow groomer comprising a support frame; a driver's cabin, which is fitted on the support frame; two track conveyors, which are fitted on opposite sides of the support frame; and a passenger cabin, which is distinct from the driver's cabin and is fitted on the support frame; the passenger cabin comprising a bearing structure; the bearing structure defining a protection cell configured to resist external loads; the bearing structure comprising housing seats; the passenger cabin comprising panels of transparent material, such as glass, which are housed in the housing seats of the bearing structure and are supported by the bearing structure.

An acoustic damping part for arrangement in a motor vehicle, a method for producing a sound-insulated vehicle body, and a motor vehicle, in particular a passenger car is provided. The acoustic damping part comprises a sound insulation element, in particular a foam element, for substantially planar contact with at least one portion of a motor vehicle body, in particular an end wall, in order to reduce the transmission of sound into a passenger compartment. Furthermore, the acoustic damping part has at least one plug part connected to the sound insulation element with a plug for insertion into an opening of a vehicle body component or component composite. This serves to produce a non-positive and/or positive connection of the acoustic damping part with material of the vehicle body component or component composite that forms the opening.
