Foamed product integral with trim cover assembly and frame element

A foamed product integral with trim cover assembly, of the type having a frame element provided therewith, wherein said trim cover assembly is preformed in a predetermined three-dimensional shape including, defined in one side thereof, a first cover portion, a second cover portion, and an opening defined between said first and second cover portions, wherein said frame element has a pair of spaced-apart local portions extending integrally therefrom, wherein said frame element as well as said pair of spaced-apart local portions are inserted through said opening and placed in an inside of said trim cover assembly, such that said pair of spaced-apart local portions projects outwardly from the trim cover assembly, after which, a liquid foaming agent is injected into said inside of said trim over assembly and cured into an increased mass of foam filled in the trim cover assembly in an integral manner, with said frame element provided integrally therein,

• said foamed product integral with trim cover assembly comprising:
• a first extension defined in said first cover portion;
• a second extension defined in said second cover potion;
• a pair of first through-holes formed in said first extension;
• a pair of second through-holes formed in said second extension;
• said first and second extension being contacted with other, such that said opening is defined therebetween, while said pair of first through-holes are in alignment with the respective said pair of second through-holes, thereby providing a pair of two-fold continuous through-holes, whereupon one unit of juxtaposed first and second extensions is provided, with said pair of two-fold continuous through-holes formed therein, said unit of juxtaposed first and second extensions projecting inwardly of said trim cover assembly;
• a pair of third through-holes formed in one of said first and second cover portions;
• said one unit of juxtaposed first and second extensions being bent to and juxtaposed upon said one of said first and second cover portions, with said pair of two-fold through-holes being in alignment with the respective said pair of third through-holes, thereby providing:
• a three-layer portion composed of said one unit of juxtaposed first and second extensions and said one of said first and second cover portions;
• and
• a pair of three-fold continuous through-holes which are respectively defined by the thus-aligned pair of two-fold through-holes and pair of third through-holes,
• said three-layer portion being situated within said trim cover assembly and at said one side of the trim cover assembly, wherein said one unit of juxtaposed first and second extensions has two lateral ends;
• a pair of spaced-apart sewn portions formed by sewing in said three-layer portion, such that one of said pair of spaced-apart sewn portions extends in a direction from one of said two lateral ends of said one unit of juxtaposed first and second extensions toward a point near to one of said pair of three-fold continuous through-holes, whereas on the other hand, another of said pair of spaced-apart sewn portions extends in a direction from another of said two lateral ends of said one unit of juxtaposed first and second extensions toward a point near to another of said pair of three-fold continuous through-holes, so that said pair of spaced-apart sewn portions define two corresponding spaced-apart closed regions in said opening, which in turn defines an opening region in between said first and second extensions, said opening region being adapted for allowing ingress therethrough of said frame element as well as said pair of local portions of the frame element into the inside of said trim cover assembly;
• and
• an unsewed region defined between said pair of three-fold continuous through-holes as well as between said pair of spaced-apart sewn portions, so that said opening region lies in said unsewed region,
• wherein said pair of local portions of said frame element pass through the respective said pair of three-fold continuous through-holes and project outwardly from said trim cover assembly.
