Title: Air bag with internal tether

Abstract: A vehicle occupant protection apparatus (10) comprises an inflator (12) and an air bag (20). The air bag (20) comprises a front panel (50) and a back panel (52) having generally circular outer peripheral portions (54, 56) sewn to each other. The front panel (50) of the air bag (20) has a retainer portion (60) defining a central opening (62) through which the inflator extends. The retainer portion (60) of the air bag (20) has a plurality of fastener openings (66) spaced apart around the central opening (62) of the retainer portion. A tether (70) extends inside the air bag (20) between the front panel (50) and the back panel (52). The tether (70) has opposite front and back end portions (76, 96). The front end portion (76) of the tether (70) has a configuration extending around the central opening (62) of the front panel (50) and around the inflator (12). The front end portion (76) of the tether (70) has an opening (78) through which the inflator (12) extends. The apparatus (10) further comprises a plurality of fasteners (48) extending through the fastener openings (66) in the retainer portion (60) of the front panel (50) to secure the front panel of the air bag (20) to the inflator (12). The fasteners (48) secure the front end portion (76) of the tether (70) to the retainer portion (60) of the front panel (50) without sewing, so that the retainer portion of the front panel is free of stitching openings.
