Patent ID: 8733250

Claim:
A metal-sealing material-feedthrough for igniters of one of a plurality of airbags and a plurality of belt tensioning devices, comprising: a base body including a feedthrough opening, a front side, a back side, and an outside circumference, said base body being configured such that a ratio of a thickness of said base body to a maximum dimension of said feedthrough opening vertical to an axis direction of said feedthrough opening is in a range of between and including 0.8 to 1.6, said base body having a thickness between 1.5 mm and 3.5 mm; a sealing material; and at least one first metal pin which is located in said feedthrough opening in said base body in said sealing material, said thickness of said base body being such that said base body has a deformation when the igniter is fired caused by compression, said deformation adding an additional force to said sealing material and thereby causing said base body at least at said front side of said base body to squeeze said sealing material such that the metal-sealing material-feedthrough is configured for avoiding a relative movement of said sealing material between said front side and said back side in a direction toward said back side relative to an inside circumference of said feedthrough opening, said deformation being such that said inside circumference of said feedthrough opening is offset relative to said outside circumference of said base body in said direction toward said back side.
