There is provided a molded body including a main portion and a bank portion each of which is formed by foaming and molding a foam material. The main portion is made of urethane material which is softer than the material for the bank portion. At a boundary portion between the main and bank portions, the main portion is formed in a continuous interlocking profile and the bank portion is also formed in another continuous interlocking profile. The interlocking profile and the another interlocking profile are mated to each other so as to prevent separation between the main portion and the bank portion in a direction of an arrow (vehicle width direction). The boundary portion is provided by partitioning the cavity in a single mold with a weir, introducing different foam materials into both sides of the weir and foaming the introduced materials.

A structural board includes a pair of intermediate members having plural projections. The intermediate members are positioned in parallel, and the projections are in contact with each other between the intermediate members. At least one of the intermediate members are light permeable. An illuminator is provided between the intermediate members.

A manufacturing method for a resin formed element capable of exhibiting an advanced design quality while reducing the manufacturing cost is provided. The method comprises the steps of printing a pattern on a reverse side of a thermoplastic film to form a printed pattern layer, printing and curing an ultraviolet curable or thermosetting resin in part of the surface of the thermoplastic film to form an ultraviolet cured or thermoset resin layer, burying this ultraviolet cured or thermoset resin layer in the thermoplastic film, and forming a resin base material from the printed pattern layer side of the laminated element to adhere and integrate, so as to produce a difference in distance from the surface between the region corresponding to the ultraviolet cured or thermoset resin layer of the printed pattern layer and other region, and finally peeling the ultraviolet cured or thermoset resin layer from the thermoplastic film.

A decorative sheet including a pattern with a third-dimensional appearance is provided. The decorative sheet has a reflective layer for reflecting incident light. On the reflective layer, a transparent layer is formed. On the transparent layer, a light shielding layer for shielding incident light is formed. A pattern layer is interposed between the light shielding layer and the reflective layer in such a manner, for example, that it is included in the rear surface of the light shielding layer or in the transparent layer. The light shielding layer is provided with a plurality of through holes for passing incident light toward the reflective layer and emission light which leads out a pattern image reflected in the reflective layer.

Decorative sheet

A sheet-shaped sensor body includes a first protective layer formed of a resist paste layer, an antenna film formed of a PET film, a first conductive layer formed of a silver layer, a second conductive layer formed of a carbon layer, a second protective layer formed of a resist paste layer and a hot-melt film, which are laminated one on another in sequence. When the hot-melt film of the sensor body is brought into abutment against a front surface of a wadding previously adhered to a pad of a seat back and is then heat-pressed, the sensor body is fixed firmly and reliably to the wadding by an adhesive force generated by the melted hot-melt film once it again cools and solidified. Thus, the sensor of an occupant detecting system for detecting the physical constitution and the attitude of an occupant sitting on a seat can be fixed easily and reliably to the seat back.

Occupant detecting system

Frictional sounds caused by molded articles, particularly molded parts for automobiles, of non-olefinic synthetic resins rubbing against one another are decreased by incorporating an amide stearate or derivative thereof in the molded article or by coating the surface of the molded article with the stearate.
