An all-glass header assembly is provided for use in an air bag system that is located in a vehicle. The header assembly acts to initiate flow of gases into the air bag. The header assembly includes an eyelet having a bore that receives an all-glass insulating body that is flush with an outer surface of the eyelet. A center electrode pin is located through a preformed hole in the center of the glass insulating body. A side electrode pin is welded to the eyelet. Electrical current flows through the two electrode pins when predetermined power is applied at a desired time. In making the all-glass header assembly, a fixture system and process are employed for achieving flushness among the eyelet, glass insulating body and center electrode pin while avoiding unwanted voids, bubbles or cracks in the glass insulating body.
A header assembly used in a vehicle air bag system in which the header assembly is used to ignite a ignitor charge by application of electrical current through a bridgewire having a diameter, comprising:
A method for making an all-glass header assembly, comprising:
