An extruded zipper for use in closing out vehicle seat backs has a first and a second flexible closure strip, each of which includes a web and a flange extending parallel to one another from an interlocking portion. The web and flange on each flexible closure strip are separated from one another by a groove, which is used to dispose the interlocking portions in a stacked relationship to one another, so that they may be joined with a hammer-like blow delivered in a direction perpendicular to the webs. The webs are attached to opposite sides of the opening in a seat back cover, which is provided in a premanufactured sack-like configuration. In a method for closing out vehicle seat backs using the extruded zipper, the grooves enable the interlocking portions of the flexible closures strips to be positioned in the required stacked relationship prior to the delivery of the interlocking blow. |
