A flexible sound barrier and rigid mounting assembly, and a method of attaching to a vehicle. The sound barrier assembly includes a rigid substrate, and flexible noise barrier and decoupling layers. The decoupling and noise barrier layers are bonded, and an adhesive bonds the decoupling layer to the substrate. The decoupling and noise barrier layers are fixedly held in place by the substrate. The substrate can include slots that fit over mounting studs on the vehicle wall. The noise barrier and decoupling layers can include mounting holes that extend through both layers, where the mounting holes line up with the slots, and fit over the mounting studs. The assembly can be mounted on the mounting studs and stud fasteners can fit through a mounting hole without compressing the noise barrier and decoupling layers and sandwich the rigid substrate surrounding a slot between the stud fastener and the vehicle wall.

A sheathing arrangement for an exhaust system of an internal combustion engine includes at least one sheathing element (18) with a sheathing element shell (19). On an inner side (30) of the sheathing element shell (19) insulation material (38) overlaps the inner side (30) in at least some areas. The inner side is to be positioned facing toward a component of an exhaust system (10), which component is to be sheathed. The insulation material (38) is fixed to the sheathing element shell (19) by means of at least one fastening element (40) passing through the sheathing element shell (19) and the insulation material (38).

An engine system (200) for a vehicle comprising: a powertrain component (120); a second vehicle component (130); a fixing (140) joining the powertrain component (120) to the second vehicle component (130); a thermally insulating panel (100) comprising at least one uncompressed area (104) extending over at least a portion of the powertrain component (120) to at least partially thermally insulate the powertrain component (120) and comprising at least one pre-compressed area (106) for providing a rigid mounting position to mount the vehicle component (130) to the powertrain component (120), the rigid mounting position to be located at a potential thermal bridge between the powertrain component (120) and the second vehicle component (130) such that it forms a thermal insulating layer between the powertrain component (120) and the second vehicle component (130).

A dam element for the damming of a structure element within a vehicle includes a support element and an expandable element. The support element consists of at least one printed strand of a first material, where the first material is in a solid physical state at least up to a temperature of from 120 C. to 200 C., and the expandable element consists of at least one printed strand of a second material, where the second material is expandable at a temperature between 120 C. and 200 C. The dam element here has, at a point of greatest thickness, measured perpendicularly to a plane of the dam element, at least two, and at most ten, mutually superposed layers.

An interior trim part (10) for cladding an inner side of a motor vehicle body has a cladding panel (12) forming an inner surface (14) and delimiting a passenger compartment. A flexible insulation layer (18) is fastened to a rear surface (16) of the cladding panel (12) that points away from the inner surface (14). The cladding panel (12) has a protruding fastening element (22) projecting through an opening (20) of the insulation layer (18). The fastening element (22) has a lateral receiving opening (28) and the insulation layer (18) has a retaining strip (32) unconnected to the rear surface (16). The retaining strip (32) is inserted into the receiving opening (28). A situation in which the fastening element (22) is covered by the extended insulation layer (18) is avoided by the retaining strip (32) inserted in the lateral receiving opening (28).

A vehicle NVH pad includes an outer pad, a support pad connected to the outer pad, and one or more inner pads pivotally connected to opposite sides of the support pad. The one or more inner pads may include a first inner pad pivotally connected to one side of the support pad through a first hinge connection and a second inner pad pivotally connected to an opposite side of the support pad through a second hinge connection.

An undercover (31) for rectifying airflow under a floor of a vehicle while driving the vehicle includes screw pedestals (42) for fixing screws (41) or nut pedestals for nuts, which are served as fastening points to a vehicle body (29). Interference caps (58) which are a molded product made from an elastic resin material are fitted between the adjacent pedestals. Under a state that the undercover (31) is engaged with and is attached to the vehicle body by the screws, a top portion (60) of the interference caps (59) is elastically deformed and is abutted to the opposite vehicle body surface, and the above abutment is maintained. Small clearance between the undercover and the vehicle body are maintained, and interference between the undercover and the vehicle due to vibration while driving is prevented, without changing the number of fastening points of the undercover to the vehicle body.

An activatable material coated device comprising a device and an activatable material, comprising at least about 5.5% or greater blowing agent, blowing agent accelerator or both. The activatable material is milled into a particulate size of from about 500 microns to about 10000 microns and the device is heated to a temperature of at least about 30 C. but below an activation temperature of the activatable material and contacted with the particulate of the activatable material, adhering the activatable material to the device.

According to an aspect, the present embodiments may be associated with a heat shield including a retention feature or member. In an embodiment, the retention member is integrated with the heat shield body and includes a trilobal shaped aperture formed therein. The trilobal shaped aperture is adapted and configured to receive and temporarily retain a fastener. Thus, the heat shield is capable of at least being temporarily held in place prior to the use of permanent installation techniques.
