Low profile igniter

摘要

An igniter includes a housing having a first end with an opening, a second end opposite the first end, a longitudinal axis extending from the first end to the second end, and a top surface with a weakened area. The igniter may further include a pyrotechnic material disposed within the housing, a header having a first end and a second end opposite the first end, and a bridge element provided on the first end of the header and having lead wires on the second end of the header. The first end of the header may be inserted into the opening of the housing in a first direction so as to force the header against the pyrotechnic material. Flow of current through the bridge element heats the bridge element and ignites the pyrotechnic material, which causes the weakened area to rupture.

主权项

1. An igniter comprising:
a housing having a first end, a second end opposite the first end, a longitudinal axis extending from the first end to the second end, a housing side wall, a bottom wall, and a top wall with a top surface, the first end having an opening, the top wall in contact with the housing side wall, the housing side wall extending around the second end, the bottom wall in contact with the housing side wall, and the top surface having a weakened area; a pyrotechnic material disposed within the housing; a header having a first end and a second end opposite the first end, the first end of the header being inserted into the opening of the housing in a first direction so as to force the header against the pyrotechnic material; and a bridge element provided on the first end of the header and having lead wires on the second end of the header, wherein
flow of current through the bridge element heats the bridge element and ignites the pyrotechnic material, which causes the weakened area to rupture, andthe housing has a hollow, rectangular cross-section in a plane perpendicular to the longitudinal axis.
