Abstract: A foaming die device for forming a headrest is provided, which comprises a lower die having a first protrusion and an upper die having a second protrusion. The lower and upper dies are used for accommodating a trim cover assembly with a headrest stay portion extending outwardly through a stay passage hole formed in the trim cover assembly. The first and second protrusions are adapted to press and turn over a projected area created about the stay passage hole into the inside of that trim cover assembly. Also, a foaming process for forming the headrest, using this foaming die device, is provided, in which the projected area is turned over by the first and second protrusions into the trim cover assembly when placing the trim cover assembly in the dies. Hence, conventional preliminary steps using cylindrical stick to turn over the projected area into the trim cover assembly are eliminated.

Abstract: Provided is a foam in place simulation method that simulates steps of forming a foam in place molded product by supplying a foaming raw material inside a surface skin that is disposed inside a mold through an inlet port thus filling a foamed body into the surface skin. The method is configured to simulate the steps of: setting a shape of the inside of the mold as a fixed boundary condition; setting a material characteristic value of the surface skin whose shape changes corresponding to a filling state of the foamed body into the surface skin; and forming the foam in place molded product from the surface skin by filling the foamed body into the surface skin based on the shape of the surface skin at the time of setting the surface skin inside the mold based on the fixed boundary condition and the material characteristic value.

Abstract: A seat cushion of a seat, which can avoid creation of wrinkle or crease in an area of a trim cover element corresponding to a lateral side of the seat cushion, irrespective of a downward load applied to the seat cushion, thereby making it possible to maintain an outer appearance of the seat cushion in a good quality condition. In a surface of a recessed region of a padding forming a part of the seat cushion, defined flexible portions are formed to be flexed in an inward direction by a downward load applied thereto. Non-bonding areas are defined between the trim cover element and the flexible portions.

Abstract: [Purpose] To provide a headrest which avoids separation of a foam padding adjacent to a headrest stay passage hole from a headrest stay.[Means for Achieving the Purpose] A patch element 20 of a doughnut-like disc shape is fixedly provided, by sewing or adhesive, to a reverse surface of a seat-back-side area 12a defined in a trim cover assembly section covering a top region 12 of a headrest HR, in such a fashion that the patch element 20 circumscribes an entire edge of a headrest stay passage hole 14. Additionally, the patch element 20 is formed from a material capable of being impregnated with a liquid foaming agent (e.g. urethane of foaming property) injected in the trim cover assembly 2. Such patch element 20 has been impregnated with the liquid foaming agent S (e.g. urethane of foaming property) injected in the trim cover assembly 2 during a foaming process to form the headrest HR. Consequently, a density of the patch element 20 itself becomes extremely high, and therefore a strength of the patch element 20 can be increased to a great degree. Further, so impregnated patch element 20 achieves its firm integral connection with a foam padding 3 that are formed from the liquid foaming agent S, thereby preventing dislocation and removal of the patch element within a main body portion 10 of the headrest.

Abstract: A foam product integral with trim cover element, which is formed by injecting a liquid polyurethane material, with carbon oxide mixed therein, into an inside of the trim cover element, and curing the liquid polyurethane material into a soft foam padding filled in the trim cover element. In this kind of foam product, a material capable of impregnation with the liquid polyurethane material is attached to an inward surface of the trim cover element. This material capable of impregnation with the liquid polyurethane material is impregnated and bonded with the resulting soft foam padding during a foaming process, and is greater in hardness than the soft foam padding, sufficient to withstand shrinkage of the soft foam padding within the trim cover element. An impregnation-preventive film, or the combination of the impregnation-preventive film and a soft polyurethane open-cell foam layer, may be attached to an inward surface of the afore-said material.

Abstract: A seat for vehicles including a seat cushion, a seat back, and a head rest has the following arrangement to ensure that a surface member can be relatively easily but positively removed from a urethane pad if a foam molding defect is found in the urethane pad in integral molding of the urethane pad and the surface member. In the seat for vehicles, any one of the seat cushion, seat back, and head rest has a configuration where a surface of the urethane pad is covered with the surface member. The urethane pad and the surface member are partially bonded together by integral molding.
