  • Patent number: 7497509
    Abstract: A fender liner includes a surface layer serving as the outermost layer and an inner layer located between the surface layer and the outer surface of a wheel well. The surface layer and the inner layer are formed of nonwoven fabric. The nonwoven fabric forming the inner layer has a higher tensile strength than that of the nonwoven fabric forming the surface layer. Accordingly, the fender liner has a favorable noise reduction capability, and has a sufficient rigidity to bear a weight increase due to water absorption. Alternatively, the nonwoven fabric forming the surface layer may have a higher bulk specific gravity and a smaller fiber diameter than those of the nonwoven fabric forming the inner layer. In this case, the noise reduction capability and the durability are both improved.

  • Patent number: 7459114
    Abstract: A method for molding an in-mold coating product including a substrate and a coating formed on a surface of the substrate. A first mold including a fixed mold piece is closed to form a substrate cavity therein. The substrate cavity is charged with a resin to form the substrate with a seal projection formed near the parting line of the first mold. Then, a second mold, which uses the fixed mold piece of the first mold, is closed with the substrate arranged on the fixed mold piece to form a coating cavity therein. The second mold deforms the seal projection so that when a coating material is charged into the coating cavity, the coating material does not leak out toward the parting line of the second mold.

  • Publication number: 20050068785
    Abstract: An illuminating device is installed at an outer side surface of a rear side door of a vehicle for illuminating a road surface section beside a front side door of the vehicle. The device is accommodated in a rear side molding secured to the outer side surface of the rear side door. The light source of the illuminating device radiates light along a linear optical path extending diagonally downward from a portion of the outer side surface of the rear side door in which the light source is installed to the road surface section beside the front side door. Further, the illuminating device includes a prism lens for refracting the light of the light source outwardly and away from the outer side surface of the vehicle body. This enables the device to effectively illuminate the road surface section beside the vehicle.
