Abstract:
The present invention relates to a metal-sealing material-feedthrough for igniters of airbags or belt tensioning devices, especially glass-metal-feedthrough, including at least one metal pin which is located in a feedthrough opening in the base body in a sealing material, wherein the base body has a front side and a back side. Structure is provided between the front and the back side in order to avoid a relative movement of sealing material in the direction toward the back relative to the inside circumference of the feedthrough opening. At least the feedthrough opening is punched out of the base body. The base body is configured so that the ratio of thickness (D) of the base body to the maximum dimension of the feedthrough opening vertical to the axis direction of the feedthrough opening is in the range of between and including 0.9 to 1.6.
