초록 ▼

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.

대표청구항 ▼

1. A method of producing a base body for a metal-sealing material-feedthrough, the method comprising the steps of: providing a blank from a wire-shaped material for processing, said wire-shaped material being made of a high grade steel and copper alloy;processing said blank by a process of cold-forming including compression and compaction to reshape said blank into an element having one of a ring-shape and a plate-shape, said element having a front side and a rear side;pressing said element against a punch, whereby the material of said element surrounds said punch in order to incorporate a relief region at said rear side of the element which is characterized by a reduced thickness,punching said element formed from said processing step to incorporate a feedthrough opening extending from said front side of the element to said rear side of the element and being located within the relief region. 2. The method according to claim 1, wherein by the pressing of said element against said punch, additional material of said element is pushed out on an opposite side. 3. The method according to claim 1, wherein the element is for a device subjected to high pressures. 4. The method according to claim 3, wherein said device is an igniter for one of an air bag and a belt tensioning device. 5. The method according to claim 4, wherein said relief region is located on a side of said base body distal to said high pressures of said igniter. 6. The method according to claim 5, further comprising punching an additional opening. 7. The method of claim 1, further comprising the steps of: inserting a sealing material into the feedthrough-opening;wherein said process of cold forming being carried out on the high grade steel and copper alloy which is configured with counter-opposing physical properties of:1) elasticity which is sufficient to allow the material to be compressed, compacted, and to surround the punch; and2) sufficient strength and rigidity to absorb ejection pressures acting upon the sealing material of between about 1350 to 3000 bar. 8. The method of claim 1, wherein: said relief region and said feedthrough opening being substantially centered in said element. 9. The method of claim 1, wherein: said reduced thickness being between about 1.5 mm and about 4.5 mm. 10. The method of claim 9, wherein: said reduced thickness being between about 2.0 mm and about 3.0 mm. 11. The method of claim 1, wherein: said high grade steel and copper alloy having a copper content of between about 1% and about 5% by weight. 12. The method of claim 11, wherein: said high grade steel and copper alloy having a copper content of between about 2% and about 4% by weight.
