An initiator assembly that includes an end plate, a plurality of terminals, a plurality of epoxy plugs, an insulator layer and an exploding foil initiator. The end plate is formed of aluminum and has a plurality of first terminal apertures formed there through. Each of the terminals is received through a corresponding one of the first terminal aperture. Each epoxy plug is received in an associated one of the first terminal apertures and is sealingly engaged to the end plate and to an associated one of the terminals. The insulator layer is received over the end plate. The exploding foil initiator is abutted against the insulator layer and has a bridge and a pair of initiator contacts. Each of the initiator contacts is electrically coupled to a corresponding one of the terminals.

A modular initiator assembly comprising a receptacle and connector combination adapted to shunt the electrical contacts of the initiator as a default condition and to only unshunt the electrical contacts coupled to the initiator when the receptacle and connector establish a fully seated connection.

An initiator assembly that includes a housing, a base, an exploding foil initiator and an input charge assembly. The housing defines a cavity. The base coupled to the housing and closes the cavity. The exploding foil initiator is mounted to the base and has a barrel that defines an initiation axis. The input charge assembly is received in the cavity and includes a holder and an input charge. The holder has a first axial end and a second axial end that are spaced apart along the initiation axis. The first axial end is closer to an output of the barrel than the second axial end. A charge aperture is formed through the first axial end of the holder and does not extend through the second axial end of the holder. The input charge is formed of an explosive material and is received into the charge aperture.

The invention relates to an ignition capsule for a gas generator of an occupant restraint system in a motor vehicle, in particular for the gas generator of an inflatable airbag, said ignition capsule comprising means for supporting extremely high pressures during ignition.

The invention relates to a hybrid inflator (10) including a burst cap (20) including a bottom (21) and a sleeve-like side wall (22), the bottom (21) and the side wall (22) delimiting an igniter compartment (23), and the burst cap (20) in the idle mode being pressurized on the outer peripheral side with compressed gas having a filling pressure (PF) which at a functional maximum temperature of the hybrid inflator (10) has a maximum filling pressure (PFmax), and wherein the burst cap (20) can be destroyed by an igniter compartment side bursting pressure in the case of operation. In accordance with the invention, a transitional portion (24) is formed from the side wall (22) of the burst cap (20) to the bottom (21) so that the igniter compartment side bursting pressure required to destroy the burst cap (20) is lower than the sum of the maximum filling pressure (PFmax) and the filling pressure (PF). The invention further relates to a burst cap, an airbag module, a vehicle safety system as well as a method of manufacturing a burst cap.

A pyrotechnical igniter (100) for an inflator of a vehicle safety system comprises 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. A fastening portion (112) in which the bridge wire (110) is welded to the contact pins (102) is provided at each of the contact pins (102).

Embodiments of an initiator support assembly that includes an initiator housing including an initiator cavity system are generally described herein. In some embodiments, a bridge substrate is positioned within the initiator cavity. The bridge substrate includes a substrate base including a uniform first planar surface and an opposed second surface. The bridge substrate further includes a first bridge contact extending over the substrate base. The first bridge contact is substantially flush with the first planar surface. A second bridge contact extends over the substrate base. The second bridge contact is substantially flush with the first planar surface. The first and second bridge contacts and the uniform first planar surface form a continuous planar mounting surface. An explosive charge, positioned within the initiator cavity, includes a charge mounting surface that is continuously coupled in surface-to-surface contact across the continuous planar mounting surface.

A modular initiator assembly comprising a receptacle and connector combination adapted to shunt the electrical contacts of the initiator as a default condition and to only unshunt the electrical contacts coupled to the initiator when the receptacle and connector establish a fully seated connection.
