1. A structure for securing a trim cover assembly of a seat back having a front side, an interior, a central portion, and a rear side in an automotive seat, comprising:

  • a back frame having a slit so formed that it is disposed at the rear side of said seat back and further extends along an internal periphery of the back frame;

    a front-side trim cover assembly which covers the front side of said seat back, extending to the rear side of said seat back and being inserted through said slit in the back frame so that edges of said front-side trim cover assembly are fixed to the interior of said seat back in a tensioned manner at a position adjacent to the central portion of said seat back; and

    a back-side trim cover assembly which covers the rear side of said seat back, said back-side trim cover assembly having securing portions provided at a peripheral end portion thereof, wherein said securing portions are made of a plate-shaped hard material and are inserted through said slit in the back frame in a tensioned manner so as to be engaged with the internal periphery of said back frame, thereby permitting the edges of said front-side trim cover assembly to press against said securing portions of said back-side trim cover assembly so that said securing portions are further brought into engagement with said internal periphery of said back frame;

    whereby both said front-side and said back-side trim cover assembly are brought into a firm contact with each other with a clear boundary therebetween at said slit in the back frame.
