Abstract
A tear away seam stabilizer for a vehicle seat component is provided for use with the pour-in-place molding process. The stabilizer, or welt, has an annular body attached to a notched tab portion by a tapered portion and neck portion which is sewn between covering members to form the desired shape of a component. A mold is provided within which the sewn cover, with the seam stabilizers in place, is inserted. The stabilizers maintain alignment of the seams in the cover member during the pour-in-place process and also prevent wrinkles in the cover. The end result is a vehicle seat component with the cover member tightly adhered to the foam body and conforming to a surface of predetermined shape. Once the foam pad is adhered to the cover member, the annular body of the stabilizer is readily torn off.
