| 主权项 | 1. A pyrotechnical igniter (100) for an inflator of a vehicle safety system comprising at least two contact pins (102) physically separated from each other by an electrically insulating compound and a bridge wire (110) connected to both contact pins (102) in an electrically conducting manner, wherein the bridge wire (110) consists of a nickel alloy with chromium at percentages of 11 to 24%, molybdenum at percentages of 12.5 to 17% and the specific resistance of the bridge wire (110) ranges from 0.25 to 3 Ωmm2/m, wherein a fastening portion (112) in which the bridge wire (110) is welded to the contact pin (102) is provided at each contact pin (102), and wherein in a top view a minimum distance (d) between a rim of the fastening portion (112) and the insulating compound is 0.01 to 0.5 mm. | ||
