Airbag igniter

Abstract

An airbag igniter ( 10 ) comprises a cup-shaped metal can ( 12 ) with a ceramic disc ( 14 ) having a conductive metal plating pattern ( 16 ) thereon positioned within the metal can ( 12 ). An RF filtering unit ( 18 ) is fixed to the disc ( 14 ). Two gold-plated, electrically conductive pins ( 20, 22 ) pass through the disc ( 14 ) and make appropriate electrical connection to the RF filtering unit ( 18 ). A sealing material ( 24 ) encloses the unit, filling the remaining volume of the cup-shaped can ( 12 ).

What is claimed is:  
     
         1 . An airbag igniter comprising: 
 a cup-shaped metal can;    an electrically insulating disc having a conductive metal plating pattern thereon positioned within said metal can;    an RF filtering unit fixed to said disc;    two gold-plated, electrically conductive pins passing through said disc and making appropriate electrical connection to said RF filtering unit; and    a sealing material enclosing said unit filling the remaining volume of said cup-shaped can.    
     
     
         2 . The airbag igniter of  claim 1  wherein said sealing material is an epoxy selected from the group of epoxies curable by ultra violet radiation, heat or ambient air.  
     
     
         3 . The airbag igniter of  claim 1  wherein said igniter is over-coated by a plastic resin.
