A method for manufacturing automotive seat assemblies using fabrics with pre-bonded adhesives. Adhesives are pre-bonded to the back surface of fabric material using a variety of processes. The fabric with pre-bonded adhesive is then cut into pieces, which may be joined with other pieces, to form a trim cover assembly. Heat is then applied to activate the adhesive and attach the trim cover assembly to a cushion pad to manufacture a complete automotive seat assembly. The invention methodology allows the use of shorter bonding cycle times to achieve a suitable bond and reduces the likelihood of omitting, improperly positioning or wrinkling the adhesive.

[ What is claimed is:] [1.] A method for manufacturing automotive seat assemblies including a cushion pad and a trim cover assembly made from fabric with a front surface and a back surface, the method comprising the steps of:pre-bonding heat-activatable adhesive to said back surface of said fabric to produce fabric with pre-bonded adhesive;cutting said fabric with pre-bonded adhesive to produce a first piece of fabric with pre-bonded adhesive;joining said first piece of fabric with pre-bonded adhesive to a second piece of fabric which is free of adhesive to form said trim cover assembly;placing said back surface of said first piece of fabric with pre-bonded adhesive forming said trim cover assembly adjacent to said cushion pad; andapplying heat to activate said adhesive and intrude a portion of said adhesive into said cushion pad, thereby attaching said first piece of fabric and thus said trim cover assembly to said cushion pad.
