Abstract
An initiator assembly for an automotive safety device includes a tubular housing with a first end and a second end. A cruciform formed in the second end of the tubular housing is designed to open when the initiator fires. A pyrotechnic load is disposed within the tubular housing at the second end, the pyrotechnic load is formed to define a void comprising an open end and a tip. The void includes sides that extend from the open end to the tip and angle toward the second end of the tubular housing and angle toward a longitudinal axis of the tubular housing. The sides of the void can transition into a tip portion of the void that comprises a geometry distinct from that of the sides.

An initiator assembly for an automotive safety device comprising:
- a tubular housing with a first end and a second end;
- a cruciform formed in the second end of the tubular housing;
- and
- a pyrotechnic load disposed within the tubular housing at the second end, the pyrotechnic load formed to define a void comprising an open end and a tip, the void further comprising sides that extend from the open end to the tip and angle toward the second end of the tubular housing and toward a longitudinal axis of the tubular housing, wherein the sides of the void transition into a tip portion of the void that comprises a geometry distinct from the sides.
An initiator assembly for an airbag cushion comprising:
- a tubular housing;
- a cruciform disposed at a second end of the tubular housing;
- and
- a pyrotechnic load disposed within the tubular housing at a distal end, the pyrotechnic load formed to define a void comprising an open end and a tip, the void further comprising a wall of a main portion extending from the open end to the tip and angling toward the distal end of the tubular housing and toward a longitudinal axis of the tubular housing, and wherein the wall of the void transitions into a tip portion of the void that comprises a geometric shape distinct from a geometric shape formed by the wall.
