Abstract
A method is provided for sewing a seat cover to provide a front panel and a side panel with an L-shaped separable seam and inner and outer chutes for air bag deployment. The method comprises sewing the front panel and the inner chute together with permanent vertical extending and horizontal extending seams that will not break during air bag deployment, and sewing the side panel and the outer chute together with permanent vertical extending seams and horizontal extending seams that will not break during air bag deployment. And thereafter sewing the front panel and the side panel together with separable vertical extending seams and horizontal extending seams that will break upon the air bag deployment to allow inflation of the air bag while the inner chute remains attached to the front panel and the outer chute remains attached to the side panel to guide the inflating air bag.
