In at least some implementations, a panel for a vehicle includes a base having an interior surface and an exterior surface, and at least one damping pad having a first surface secured to the exterior surface of the base and a second surface opposite to the first surface. The at least one damping pad has a thickness measured between the first surface and the second surface, and the thickness of the at least one damping pad in an uncompressed state prior to installation into the vehicle is at least 5% greater than a thickness of the at least one damping pad in a compressed state when installed into the vehicle.

A body part for a road vehicle comprising:

an outer portion configured to be arranged on the outer side of a road vehicle and defining a first side of the roof panel; an inner portion configured to be arranged, with respect to the outer portion, towards a passenger compartment of the road vehicle and defining a second side of roof panel; wherein the outer portion comprises one or more first composite material layers; and the inner portion comprises at least one or more second composite material layers; an intermediate portion arranged between the inner portion and the outer portion; wherein the intermediate portion comprises, in turn, a layer of sound-absorbing material; and wherein the inner portion, the intermediate portion and the outer portion are integrally coupled together forming a single multilayer body.

A roof structure of a motor vehicle includes an outer sheet and a headliner below the outer sheet. A telematics control unit (TCU) is disposed in an insulated space of the roof structure. The TCU is configured to provide Wi-Fi within a passenger space of the vehicle above an electrically non-conductive grille extending across an opening in the headliner. The grille permits airflow between the insulated space and a passenger space below the headliner to cool the TCU, without interfering with Wi-Fi signals from the TCU.

A vehicle includes a floor and an electric battery placed beneath the floor. The vehicle also includes a layer of sound-deadening foam inserted between the floor and the battery such that the layer has an upper surface that is in contact with the floor and a lower surface that is in contact with the battery. At least one the two surfaces forms at least a seal intended to increase the sound-deadening of the foam between the floor and the battery.

A vehicle interior component including a plurality of functional parts and a method of manufacturing the same are provided. A headliner which is a vehicle interior component includes a sheet-like core member formed of a urethane foam. The headliner has a plurality of functional parts with different functions set in a plane of the headliner. The core member has an in-plane distribution of a characteristic of the urethane foam varied corresponding to the plurality of functional parts.

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.

A cowl assembly for a vehicle is provided with integrated water management without the need for drainage grommets or hoses. The cowl assembly includes at least one cowl panel disposed adjacent a rear section of an engine compartment and extending a distance across a transverse width direction of the vehicle. A cowl insulator component is disposed adjacent to the cowl panel, also extending across the transverse width direction of the vehicle. At least one region of a major surface of the cowl insulator component is provided with a fluid resistant barrier layer configured to route fluid in a direction away from the engine compartment.

This storage unit is configured to store an outside-of-panel acoustic transfer function that is an acoustic transfer function involving an airborne sound that is a sound emitted from a sound source located outside a panel member and propagated through the air to an outer surface of the panel member, and a panel transmission function that is an acoustic transfer function from the outer surface of the panel member to an inner surface of the panel member. This sound transmission analyzing unit is configured to calculate, based on the outside-of-panel acoustic transfer function and the panel transmission function, an acoustic transfer function from the sound source via the air to the inner surface of the panel member.

A vehicle body side part structure includes: a center pillar having a base expanding in a fan shape; an inner center pillar having filling openings formed in vicinity to front and rear inwardly-curved corners of the base; a center pillar stiffener defining a filled space to extend in a front-rear direction between the center pillar stiffener and inner center pillar; a side sill joined to lower ends of the inner center pillar and center pillar stiffener; and a partition member having front and rear cover portions and a main body integrated with the cover portions. The partition member includes a filled space partitioner to partition the filled space into a first filled space located closer to one of the inwardly-curved corners and a second filled space located closer to the other of the inwardly-curved corners so as to have a volume substantially equal to that of the first filled space.

An operator cab for a work vehicle includes: a cab enclosure including a roof an operator chair disposed in the cab enclosure; at least one layer of noise-deadening material coupled to the roof; and a headliner coupled to the roof such that the at least one layer of noise-deadening material is at least partially disposed between the headliner and the roof. The headliner includes a noise-reflective material and a noise escape region that comprises at least one opening configured to allow sound waves to pass through the noise escape region into the at least one layer of noise-deadening material and reduce noise reflection by the headliner to the operator chair.
