A vehicle roof stiffener includes a metal or metal alloy frame defining a central opening and at least one corner. The vehicle roof stiffener also includes a fiber reinforced polymer (FRP) portion including at least one transition structure comprising a metal or a metal alloy. At least some of the fibers of the FRP portion are embedded in the transition structure. The FRP portion is located in the at least one corner. In some examples, the frame includes an opening in the at least one corner, and the FRP portion spans the opening. In other examples, the FRP portion overlaps the frame at the at least one corner. The FRP portion located at the corner may improve rigidity of the roof stiffener to increase resistance to a racking motion and increase the overall stiffness of the vehicle.

An integral component of a vehicle body includes an open profiled element and a reinforcing rib structure disposed in an interior of the open profiled element. The open profiled element has a fiber-plastics composite body having a first structure, and at least one reinforcement panel from metal for the localized reinforcement of the profiled element. The reinforcing rib structure is produced from a fiber-plastics composite having a second structure.

An embodiment floor structure of a vehicle includes a pair of side seals disposed to face each other in a vehicle width direction, and respectively disposed in a vehicle length direction, a floor frame disposed between the pair of side seals and including a pair of longitudinal frames respectively arranged along the pair of side seals and at least one transverse frame mounted between the pair of longitudinal frames in the vehicle width direction, and at least one core structural member disposed in a space provided by the floor frame and including a material for absorbing impact.

A trailer coupling for a motor vehicle comprises a coupling arm, on the free end region of which a ball neck is formed, on which a coupling ball is arranged. The coupling ball is spherical on the side facing away from the ball neck and has a spherical segment plane on the side facing the ball neck. Between the spherical segment plane and a portion of the ball neck has a smaller outer circumference than the spherical segment plane there is arranged a throat portion having a transition contour extending in a concave manner between the ball neck and the spherical segment. The transition contour transitions with a coupling ball transition region into an external contour of the coupling ball and transitions with a ball neck transition region into an outer surface of the ball neck. The transition contour has a curved configuration having a non-constant radius.

A crashworthiness energy absorption part includes: a tubular member having tensile strength of 590 to 1180 MPa grade; a closed cross section space forming wall part having tensile strength lower than the tubular member and having both edge portions joined to inner surfaces of a pair of side wall portions of the tubular member, and forming a closed cross section space between the closed cross section space forming wall part and a part of a peripheral wall portion of the tubular member; and a resin configured to fill the closed cross section space, includes a rubber-modified epoxy resin and a curing agent, and has tensile breaking elongation of 80% or more, adhesive strength to the tubular member and closed cross section space forming wall part of 12 MPa or higher, and a compression nominal stress of 6 MPa or higher at a compression nominal strain of 10%.

An instrument panel reinforcement includes a cylindrical-shaped portion being formed as a single piece, being disposed at a driver's seat side, and extending in a vehicle width direction, and a groove-shaped portion being disposed at a front passenger's seat side, extending in the vehicle width direction, and opening in a predetermined direction. The instrument panel reinforcement is provided for a vehicle. The groove-shaped portion includes a reinforcement member being made of synthetic resin and mounted on a predetermined part of the groove-shaped portion, the part being away from the cylindrical-shaped portion by a predetermined distance.

A shipping trailer wall panel includes a first partially hollow section, a second partially hollow section, and a reinforcing section. The first partially hollow section includes a first plurality of cell walls. The second partially hollow section is interlockingly connected to the first partially hollow section. The second partially hollow section includes a second plurality of cell walls. The reinforcing section is connected to one or more of the first partially hollow section and the second partially hollow section.

A rear deck post assembly is provided for reinforcing a cargo bed of a utility vehicle. The assembly includes a first deck mount coupled to a vehicle frame, and a first rear deck post coupled to the first deck mount. A second deck mount is provided coupled to the vehicle frame and spaced apart from the first deck mount. A second rear deck post is coupled to the second deck mount. A deck sill component is provided longitudinally extending between the first deck post and the second deck post. Deck bolts may be used to couple the deck sill component, deck mounts, and deck posts to the vehicle frame. The first and second deck mounts and deck posts may be a cast aluminum alloy, a cast magnesium alloy, or a fiber reinforced composite material.

A vehicular pillar structure including: a first pillar which is included in a part of a front pillar, and extends along a generally upward and downward direction of a vehicle, and to which a front windshield glass is bonded; a second pillar which is included in another part of the front pillar, is arranged on a rear side of the vehicle at a predetermined spacing from the first pillar, and extends along a generally upward and downward direction of the vehicle; a transparent member with which the first pillar and the second pillar are bridged, and through which an exterior of the vehicle is visible from a driver side; and a molding which is disposed in at least a peripheral portion closer to the front windshield glass in the transparent member, and includes a bond portion that attaches the transparent member to at least the first pillar, and a closure portion that closes a gap between the transparent member and the front windshield glass is provided.

The roof of a vehicle includes a passive cooling layer overlaying an outward facing surface of the roof such that the layer is exposed to sunlight exterior to the vehicle. The layer includes a polymer having molecular structures with SiOSi linkages. The layer has relatively high emittance over a peak spectrum for solar heating.
