An initiator for a gas generator of a vehicle safety device includes a cup defining an interior, a primary pyrotechnic material disposed in the interior of the cup, and a secondary pyrotechnic material disposed in the interior of the cup. A separator member hermetically separates the primary pyrotechnic material from the secondary pyrotechnic material.

Initiator for a gas generator of vehicle safety device

An initiator for a gas generator of a vehicle safety device includes a cup defining an interior, a primary pyrotechnic material disposed in a primary combustion chamber in the interior of the cup, and a pair of electrical pins in reaction initiating communication with the primary pyrotechnic material through a bridge wire. The bridge wire is in reaction initiating contact with the primary pyrotechnic material at a first end of the primary pyrotechnic material. The primary pyrotechnic material is compacted within the primary combustion chamber to include a depression at a second end of the primary pyrotechnic material, the second end opposite the first end.

Initiator for a gas generator of a vehicle safety device

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.

Initiator for an automotive safety device

A metallic case for a pyrotechnical igniter of a gas generator for a vehicle safety device that includes a peripheral side wall, a closed end, and a weak zone in the peripheral side wall. The weak zone extends along a continuous trace having a first end portion, a second end portion, and an intermediate portion between the first and second end portions. The first and second end portions of the continuous trace both transition from a first point having a first side wall depth to a second point having a second side wall depth. The second side wall depth is greater than the first side wall depth. The weak zone is configured for opening a vent in the peripheral side wall in response to an increase of pressure within the metallic case.
