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).

A nonwoven molded article may include at least one thermoformed nonwoven fabric. The fabric may include structural fibers having polyethylene terephthalate, first bicomponent binder fibers, optional second binder fibers, and optional additives. The first bicomponent binder fibers may include matrix-forming polyethylene-terephthalate having a semicrystalline sheathing material having a melting point ranging from 90 to 175° C. The optional second bicomponent binder fibers may include matrix-forming polyethylene-terephthalate having a semicrystalline sheathing material and differ from the first bicomponent binder fibers.

A vehicle undercover mounting bracket for mounting an undercover body is provided. The vehicle undercover mounting bracket includes a frame-side mounting portion mounted on a side rail of a truck frame, an undercover-side mounting portion mounted on the undercover body and spaced apart from the frame-side mounting portion in a longitudinal direction of the side rail, and a connecting portion which extends in the longitudinal direction of the side rail and connects the frame-side mounting portion and the undercover-side mounting portion.

There is provided a maintenance cover member including: a cover body for closing an opening of a power train of a vehicle; and a vibration suppressing member attached to a surface of the cover body. There is also provided a maintenance cover member including: a cover body for closing an opening of a power train of a vehicle; and a plurality of vibration suppressing members attached to a surface of the cover body. Adjacent vibration suppressing members are disposed spaced apart from each other.

A device for reinforcing, sealing or insulating a structural element in a motor vehicle includes a support having a clip for pre-fixing the device in the structural element. The clip includes a base and two flexible wings arranged on the base. The device furthermore includes an adhesive for adhesively bonding the support in the structural element. The device furthermore includes an insertion element, which can be inserted in such a way into an interspace between the base and the wings of the clip when the device is pre-fixed on the structural element by the clip that the flexible wings are restricted in their freedom of movement.

A planar motor vehicle lining component made of a plastic-containing material, having a liner portion of predetermined shape which is embodied to cover, in the completely installed state, a predetermined area on a motor vehicle, the lining component includes at least one reinforcing portion that is connected to the lining portion and is connected by means of a hinge portion to the lining portion foldably in such a way that a supporting surface region of the reinforcing portion is conveyable, by folding over the reinforcing portion, into abutting engagement with an abutting surface region of the lining portion.

The present invention discloses an integrally molded vehicular undercover having air permeability includes a base material layer containing inorganic fibers and a first solidified thermoplastic binder, the base material layer having a road side surface and a vehicle body side surface, an outer layer containing synthetic resin fibers and a second solidified thermoplastic binder, the outer layer being integrated with the road side surface of the base material layer, and a synthetic resin layer having air permeability, the synthetic resin layer being integrated with the vehicle body side surface of the base material layer.

Presented are multilayer, fiber-reinforced impact protection structures with honeycomb-core or corrugated-layer designs, methods for making/using such structures, and vehicles with traction battery packs supported on skid plates fabricated from such structures. A multilayer impact protection structure includes a first layer with continuous fibers embedded in a polymeric matrix, and a second layer that is attached to the first layer and includes an elastomeric polymer. A third layer, which is attached to one side of the first layer opposite that of the second layer, includes a fiber-reinforced polymer honeycomb and/or corrugated structure. An optional fracture detection circuit is attached to the first or third layer, and is configured to detect a break in the impact protection structure. The corrugated structure may include multiple reinforcement ribs that are interposed within and substantially orthogonal to a series of mutually parallel, elongated ridges. Comparatively, the honeycomb structure includes a lattice of adjoining polygonal cells.

A low-noise pocket-type wheel guard is provided and includes a guard that is installed to face a surface of a tire in a vehicle, in which a noise reduction pocket is formed to protrude toward an interior of the vehicle in the guard. Since the noise reduction pocket is formed on the end portion of the wheel guard, in which a sound field is expected to be formed due to tire pattern noise, formation of a sound field due to the tire pattern noise is disturbed and prevented.

A thermal radiation shield for the floors and roofs of trailer reefer units. 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.
