Method for forming a foamed product integral with trim cover assembly, in which a foam padding piece and a surface cover piece are formed such that the former is small in size relative to the latter. According to the method, the peripheral ends of the foam padding piece are aligned and sewn with the peripheral ends of the surface cover piece to form a cover section. A plurality of such cover sections are provided and are bent at their respective end portions, stretching each surface cover piece on and over each foam padding piece, after which, the thus-bend end portions of cover sections are sewn with one another to form a three-dimensional trim cover assembly. A liquid foaming material is injected and cured in that trim cover assembly to form a foamed product integral with the trim cover assembly.

Method for forming a foamed product integral with trim cover assembly

A structure of bonding die for use with a trim cover assembly having a connected portion where one cover section thereof is sewn with another cover section thereof, and for pressure bonding the trim cover assembly to a foam cushion member. A retainer member is provided on the die, which is formed by bending a rigid wire material into a loop-like shape such as to have an inward elastic deformability give therein. Such retainer member permits its smooth insertion into the connected portion of trim cover assembly, without any tear and damage caused in the trim cover assembly per se, to thereby provide an easy and precise location of the trim cover assembly with respect to the foam cushion member.
