Structure for mounting an air bag in an air bag system

A structure for mounting an air bag in an air bag system comprising:

• a retainer having an inflator mounting opening, and a plurality of first and second openings around the inflator mounting opening,
• an air bag having an inflator receiving opening aligned with the inflator mounting opening, a peripheral edge around the inflator receiving opening, and a plurality of third and fourth openings at the peripheral edge, said third and fourth openings corresponding to the first and second openings, respectively,
• a press ring situated above the peripheral edge of the air bag to hold the peripheral edge of the air bag relative to the retainer, said press ring having a plurality of fifth openings,
• an annular sheet made of synthetic resin and situated between the press ring and the peripheral edge of the air bag, said sheet having a plurality of first projections extending upwardly from the sheet and a plurality of second projections extending downwardly from the sheet so that when the air bag is assembled, the first projections engage the fifth openings of the press ring without projecting outwardly beyond an upper surface of the press ring, and the second projections extend through the third openings of the air bag and engage the first openings of the retainer to immovably hold the peripheral edge of the air bag relative to the retainer and the press ring by the first and second projections, said annular sheet having a plurality of sixth openings corresponding to the second and fourth openings, and
• means for securing the press ring to the retainer, said securing means passing through the second, fourth and sixth openings to thereby securely fix the press ring and the peripheral edge of the air bag to the retainer.
