  • Publication number: 20180050619
    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.

  • Patent number: 9751443
    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.

  • Patent number: 9616788
    Abstract: 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 injected in the trim cover assembly 2. Such patch element 20 has been impregnated with the liquid foaming agent S 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.

  • Patent number: 9610875
    Abstract: A trim cover assembly of extremely soft property comprises a surface cover element, a wadding cover, and a thick foam wadding sandwiched therebetween, wherein the thick foam wadding has a compressed thin end surface region sewn with the surface cover element and wadding cover. Sewing method for forming such trim cover assembly involves: pressing and collapsing an end surface of the thick foam wadding in downwardly slantwise direction to provide a compressed thin area, thereby allowing direct access thereto of a conventional sewing machine; operating the sewing machine to sew the compressed thin area with the surface cover element, thereby producing a sewn trim cover having a compressed thin end region therein; and thereafter sewing the wadding cover with such sewn trim cover in correspondence with the compressed thin end region. As such, a trim cover assembly having the thick foam wadding is easily formed by the conventional sewing machine.
