Air bag attachment to module
First Claim
1. A method of attaching an air bag to an air bag module, the module including an inflator for discharging inflator gas to inflate the air bag, the method comprising the steps of:
- providing the air bag made of a flexible fabric air bag material;
cutting the air bag material into flap portions which cooperatively form the shape of an air bag opening for receiving inflator gas therethrough;
folding back the flap portions to open the air bag opening;
fastening the flap portions to the module; and
sewing a seam around a perimeter of each of the flap portions prior to cutting the air bag material into flap portions.

Abstract
An air bag module includes a base plate and an inflator mounted to the base plate. The inflator discharges inflator gas to inflate an air bag. The air bag includes an air bag opening for receiving inflator gas therethrough. The air bag is made of a flexible fabric air bag material. The air bag also includes a mouth portion surrounding the air bag opening. The mouth portion includes a plurality of flap portions. Each of the flap portions is a continuous extension of the air bag material and each of the flap portions is connected to the base plate to anchor the air bag during air bag deployment. The flap portions cooperatively define the shape of the air bag opening and are each formed by cutting the air bag material to form the air bag opening.
