  • Patent number: 8758875
    Abstract: A formable laid interior decoration material (10) for an automobile is formed by laminating air-permeable design layer (11), apertured resin layer (12) having formed a plurality of apertures (12a) penetrating it in a thickness direction, shape-retaining felt layer (13) containing melted fibers, non-air-permeable resin sheet layer (14), and padding material (15), in this order. Formable laid interior decoration material (10) for an automobile is formed in a shape that conforms to a shape at a location where the material is laid in the automobile. The laminated body of air-permeable design layer (11), apertured resin layer (12), and shape-retaining felt layer (13) preferably has an air permeability of 1 to 30 cc/cm2/second.

  • Patent number: 8740440
    Abstract: A light guide plate has a light guide plate body and at one side thereof a curvedly descending portion formed by curving front and rear surfaces of the light guide plate, with the surface to surface distance kept uniform, to a coaxial arcuate configuration so as to extend towards a direction of a rear surface of the light guide plate body. Spot light sources disposed in face to face relation with a free end face of the curvedly descending portion are arranged to be displaced towards the front surface of the light guide plate from a mid-center plane between the front and rear surfaces of the curvedly descending portion.

  • Patent number: 8167335
    Abstract: The present invention discloses a fender liner attached to a motor vehicle wheel house. The fender liner includes a breathable base material layer produced by forming a fiber assembly into a shape along the wheel house and a protective layer made of waterproof material. The protective layer is superimposed on a surface of the base material layer that is opposite to a side facing the wheel house. The protective layer is provided with a plurality of through-holes that allow air to flow through the protective layer to the surface of the base material layer on which the protective layer is superimposed.

  • Patent number: 7661703
    Abstract: A cut that widens a through hole of an end portion of a headliner interior material breaks when an airbag is deployed, and is formed on an exterior-side of the end portion. The end portion of the headliner interior material is in close contact with a surrounding member provided around the end portion. In addition, an accessory is passed through the through hole and fixed to a body, while the end portion of the headliner interior material is held to the accessory around the through hole. When the airbag installed folded on the exterior side of the headliner interior material is deployed, the airbag deploys into a cabin from between the end portion and the surrounding member.

  • Patent number: 7566088
    Abstract: A sun visor for an automobile having a plate-like core provided with multiple micropores each having a diameter ranging from 1 to 5 mm. Open area ratio representing the ratio of the total area of micropores to the projected area of the plate-like core ranges from 2% to 30%. Alternatively, a sun visor for an automobile has a skeletonic core having an air permeability equal to that of the plate-like core provided with multiple micropores. The plate-like core or the skeletonic core is covered with a covering member having a high air permeability.
