ABSTRACT:
A pull strap handle (10) for an automotive interior is fully cushioned by forming a foamed resin cushion (20) that is fit around and over both faces of a strap (15) for the handle. A backing bar (30) is then positioned to extend over cushion (20) and be spaced from strap (15), and a resin cover (25) is wrapped over the cushion and over backing bar (30) so that edges of the cover overlap adjacent the backing bar. Then a dielectric bonding bar (31) presses the overlapping edges of cover (25) against the metal backing bar so that the cover edges are dielectrically bonded together in a seam that preferably has the same surface texture pattern as the rest of the cover material, so as to be inconspicuous. Then backing bar (30) is slid endwise out from under cover (25), to leave the seam (32) spaced from strap (15) by the thickness of cushion (20) which can extend all around and over both faces of the strap. Handle ( 10) is then completed by forming the strap and providing end anchorages, as is generally known.
