A ring-shaped or plate-like element, in particular for a metal-sealing material-feedthrough, for example for devices which are subjected to high pressures, such as igniters for airbags or belt tensioning devices, includes a feedthrough opening, whereby the feedthrough opening is located substantially in the center of the ring-shaped or plate-like element and whereby the ring-shaped or plate-like element has a thickness. The ring-shaped or plate-like element has a relief region in the area of the feedthrough opening. Further, the ring-shaped or plate-like element in the relief region has at least one thickness which is reduced by the height of the relief region and which is selected so that the feedthrough opening can be punched out of the ring-shaped or plate like element having the reducing thickness.
A ring-shaped or plate-like shaped element for a metal-sealing material-feedthrough subject to high pressures in an igniter for one of an airbag and a belt tensioning device, the element comprising a feedthrough opening located substantially in a center of the element and a relief region in an area of said feedthrough opening, the element having an entire thickness (D) and at least one reduced thickness (DR) in said relief region, said at least one reduced thickness (DR) being said entire thickness (D) reduced by a height (HF) of said relief region and selected so that said feedthrough opening can be punched out of the element having said at least one reduced thickness (DR).
A metal-sealing material-feedthrough subject to high pressures in an igniter for one of an airbag and a belt tensioning device, the metal-sealing material-feedthrough comprising one metal pin arranged in an opening in a base body in a sealing material, said base body being one of a ring-shaped element and a plate-like element, said opening in said base body in which said metal pin is arranged being a feedthrough opening of one of said ring-shaped element and said plate-like element.
A method of producing an element having one of a ring-shape and a plate-like shape for a metal-sealing material-feedthrough, the method comprising the steps of:
A method of producing a metal-sealing-feedthrough, comprising the steps of:
