A metal fixing material leadthrough for igniters of airbags and/or belt tighteners includes at least one metal pin fused into a glass or glass-ceramic fixing material in a through-opening of a main body. The metal is present in a post-heated state, with an interface between the fixing material and the metal pin and an additional interface between the fixing material and an inner surface of the through-opening. The at least one metal pin, at least in its core region, consists of stainless steel, such as a chromium-containing stainless steel, the stainless steel having a thermal expansion coefficient.

Metal fixing material leadthrough having low susceptibility to faults

A metal-fixing material feedthrough for at least one of an airbag igniter or a belt pre-tensioner includes a main body having a through opening formed therein and at least one metal pin fused into the through opening in a vitreous or glass ceramic fixing material. A surface of the vitreous or glass ceramic fixing material is a freely fused surface and lies in a same plane as an end face of the at least one metal pin.

Metal-fixing material feedthrough, method for the production thereof and uses thereof

The present disclosure relates to components, such as base bodies, for feed-through elements including a metallic base body, at least one through-opening for receiving a functional element in a fixing material, such as an electrically insulating fixing material, and at least one conductor, which is connected electrically conductively to the base body by a soldered connection. The soldered connection includes a metallic solder material that covers a surface region of the base body and thus forms a soldering region on a surface of the base body. The base body has, at least in the soldering region, a microstructuring that includes at least depressions in the surface of the base body. The present disclosure similarly relates to methods for producing such base bodies and to applications thereof.

Base body with soldered-on ground pin, method for its production and uses thereof

A sensor component housing includes at least one tube section with a tube wall, wherein the tube wall has an opening and the tube section has a diameter and a first and second end. The first and/or the second end has tilted areas such that the diameter tapers to an end diameter toward the first and/or the second end of the tube section.

Sensor component housing

A feed-through element of an ignition device for igniters of airbags or seatbelt tighteners is provided. The feed-through element has a metal support body, at least one first access opening in which a metal rod is arranged in an electrically insulating fixing material, and at least one second access opening in which a further metal rod is electrically conductively fixed to the support body by a soldered connection in this access opening. The support body and the access openings are configured as a shaped part. The feed-through element further includes a solder gap between the metal rod and the wall of the second access opening, where the solder gap has a small width.

Shaped feed-through element with contact rod soldered in

A glass-to-metal bushing for ignitors of airbags or belt tensioning pulleys. A metal pin is arranged in a slot in the base plate in the fixing material, the base plate being formed by one element whereby the base geometry describing the slot is produced by at least one separation process. Structure is provided between the front and rear of the base plate for preventing relative motion of the fixing material in the direction of the base plate rear portion across from the inner circumference of the slot.
