Abstract:
1. A method for manufacturing an igniter for air bags or belt tensioning pulleys, comprising: stamping or punching from a metal sheet a base plate having a thickness of between 1.5 and 3.5 mm and a final outer geometry; punching or stamping in the base plate an opening extending therethrough, said opening having at least one retention structure forming an undercut, said opening having a maximum diameter in a range of between and including 1.8 to 4 mm; inserting a metal pin and a plug of fixing material into the opening wherein the pin is disposed within the fixing material and protrudes beyond a rear surface of the base plate, a portion of the fixing material being mechanically retained by the undercut to prevent movement of the fixing material plug relative to the base plate in a direction toward the rear surface of the base plate.
