1. A foaming die device of such a type that allows a basic armrest unit to be placed therein and also allows said basic armrest unit to be subjected to foaming therein, wherein said basic armrest unit comprises:

  • a three-dimensional trim cover assembly of a predetermined shape of armrest body;

    said three-dimensional trim cover assembly including a through-hole formed therein;

    a support element disposed in an inside of said three-dimensional trim cover assembly, said support element having two end portions projecting outwardly through said through-hole of the three-dimensional trim cover assembly; and

    a connecting bracket rotatably secured to one of said two end portions of said support element, said connecting bracket being thus disposed exteriorly of the three-dimensional trim cover assembly, and wherein, at said foaming process, a liquid foaming agent is to be injected into the inside of said three-dimensional trim cover assembly and then cured into an increased mass of foam padding filled in the three-dimensional trim cover assembly, thereby forming a resultant armrest having said connecting bracket provided exteriorly thereof in a rotatable manner,said foaming die device comprising;

    a first die element;

    a second die element movable for engagement with said first die element to define a working die area therein, said working die area being adapted to allow said three-dimensional trim cover assembly to be placed therein; and

    an auxiliary die element to be incorporated in said working die area defined by said first and second die elements, said auxiliary die element being of a split type comprising a first die piece and a second die piece in such a manner as to allow said first and second die pieces to be mated together, with said support element disposed therebetween, in a direction orthogonal with an axis of the support element, so that the thus-mated first and second die pieces enclose said connecting bracket and slidably engages the support element, thereby allowing the mated first and second die pieces to be slidingly movable along said support element towards said through-hole of said three-dimensional trim cover assembly so as to allow insertion of a part of said mated first and second die pieces in said particular through-hole.
