Abstract:
1. An ignition device for a pyrotechnic protection device, comprising: a metal carrier part having a disk-like base body with a top surface, a bottom surface, and an outside edge; a welding rim arranged at the outside edge of the disk-like base body and extending in a first axial direction away from the bottom surface; a first metal pin in an opening in the disk-like base body and extending in the first axial direction; a glass insulation material between the first metal pin and the opening of the disk-like base body; a second metal pin in electrical communication with the bottom surface of the metal carrier part and extending in the first axial direction; a propellant charge on the top surface disk-like base body and extending in a second axial direction away from the top surface; a cap enclosing the propellant charge between the disk-like base body and the cap; and an encircling weld seam securing a bottom periphery of the cap to the welding rim, wherein the welding rim is sufficient to maintain a peak temperature of the glass insulation material, during formation of the encircling weld seam, to at most 275° C.
