Abstract: The invention relates to a method for producing hardened profiles, in particular hardened open profiles, wherein the component is at least partly heated to above the austenitizing temperature of the base material and after heating the component is cooled at a rate above the critical hardening rate, the energy necessary for the heating being introduced at least partly by induction, wherein free edges are provided in the component to adjust a temperature or hardness gradient over the cross section of the component, the size, type and extension of the edges being set for a desired degree of hardness and/or hardness gradient.

Abstract: In a gas generator for a vehicle protection system having an outer jacket and an inner housing attached thereto through an edge union and consisting of an ignition carrier and a thin-walled propellant vessel, which inner housing together with a primer and a propellant charge forms a hermetically encapsulated separate structural unit, an edge lip of the ignition carrier bent radially inward over the collar type enlarged propellant vessel edge is provided, which, when the inner housing is installed in the outer jacket, is pressed axially against a stepped abutment surface of the outer jacket and is thereby held in tight press-fit engagement on the collar-like vessel edge. Due to this the gas generator has, in terms of manufacture, a very simple construction in the region of the ignition carrier attachment to the propellant vessel but yet is highly burstproof.
