A vehicle body rear structure includes: a cross member and a curvature portion each formed by a part of a floor panel, the part projecting downward at a rearward portion (spare tire pan) of the floor panel, wherein the cross member and the curvature portion each constitute a projected portion; and an underbody coating applied to the projected portions and having a first step and a second step which are oriented perpendicular to a front-rear direction.

A system for insulating a structural element in a motor vehicle, including a structural element and a device arranged thereon and having a carrier. The system also includes an expandable adhesive, which is arranged on the structural element or on the carrier via pumping or via extrusion. The carrier and the expandable adhesive are designed and arranged in such a way that the carrier limits the expandable adhesive in at least one direction during the expansion of same.

Floor panel vibration is reduced by suppressing a mode in which an entire region surrounded by a plurality of frame members in a floor panel vibrates. Vehicle-body framework members having closed cross-section structures, and a panel member to which vibration is transmitted from an engine or/and a suspension via the vehicle-body framework members are provided. The panel member includes a flange portion having a planar shape on its outer peripheral edge and to which the vehicle-body framework members are joined along the panel outer peripheral edge; a curved surface portion that is curved such that a place closer to a panel central side bulges out more to a lower side in a continuous manner from a panel-central-side edge portion of the flange portion; and a flat surface portion that extends to the panel central side from the panel-central-side edge portion of the curved surface portion in a continuous manner.

A underbody structure includes a tunnel brace (22) laid on a floor tunnel (18) of a vehicle. The tunnel brace (22) has a front convex section (71), a central groove section (72) and a rear convex section (73). The front convex section (71), the central groove section (72) and the rear convex section (73) are formed to have equal width dimensions with each other. The tunnel brace (22) is formed so as to have an M-shaped cross section by the front convex section (71), the central groove section (72) and the rear convex section (73). The tunnel brace (22) is formed such that the width dimension of the tunnel brace in the vehicle body forward/rearward direction has a maximum value at right and left end portions (22a, 22b) and has a minimum value at a central section (22c).

An acoustic dash panel seal and assembly guide for a vehicle having a dash panel with a shaft aperture configured to receive a steering column shaft includes a guide portion having a converging wall that converges from a first end to an opposite second end, and a flange portion extending from the converging wall first end. The guide portion second end is configured to be disposed proximate to the dash panel shaft aperture, and the guide portion first end is configured to receive the steering column shaft therein during assembly of the vehicle. The converging wall is configured to guide the steering column shaft toward and through the guide portion second end to thereby guide the steering column shaft through the dash panel shaft aperture.

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 dash insulation pad for a vehicle, which is manufactured by adding thermoexpandable microcapsules when a sound insulation sheet is manufactured so that the sound insulation sheet which is heavy is lightened, to obtain required performance thereof, which is equal to or higher than that of a conventional sound insulation sheet. Particularly, a dash insulation pad for a vehicle, in which thermoexpandable microcapsules individually expanding to form air pores are added to and foamed in a sound insulation sheet so that cells in the sound insulation sheet are independently and uniformly formed even without using chemical gas and the like so that the dash insulation pad is uniformly formed and lightened.

A thermal radiation shield for the floors of an RV unit, and for the various floor, ceiling, sidewalls of a slide out for said RV unit. The shield includes a low-emissivity, heat reflecting film that includes a metal coating layer, preferably vapor deposited, further protected by a layer of durable PET film.

A vehicle floor silencer includes at least one first wall, at least one second wall positioned opposite the first wall, and at least one floor extending between the at least one first wall and the at least one second wall. The at least one first wall, the at least one second wall, and the at least one floor combine to define a receptacle structured to open in an upward direction and to receive a wire harness therein after the floor silencer has been positioned on the floor of the vehicle.

A sandwich-type, composite component having a sprayed backside protective coating is provided. The component includes a first outer layer having an outer surface, a second outer layer and a core positioned between and bonded to the outer layers and having a plurality of cavities. The protective coating is integrally formed from an elastomeric material. The material is sprayed to form the coating and the coating is bonded to the outer surface by curing. The component may be a vehicle interior component such as a vehicle load floor component.
