ABSTRACT:
An ignition assembly in a motor vehicle inflatable safety system is provided, preferably to be used with a projectile. In one embodiment, the ignition assembly includes an actuation piston and an activator, such as a percussion primer(s) and an ignition material, which are separated by a retention pin. When a sufficient force is exerted on the actuation piston, the retention pin fails such that the actuation piston moves and impacts the percussion primer(s) to ignite the propellant within the gas generator. The resulting propellant gases are thereafter provided in a predetermined direction(s). Advantageously, a check valve-like device is employed to substantially reduce the flow of propellant gases in a direction other than the predetermined direction(s). The preferred projectile also includes a body that has a smaller dimension than the projectile piercing head when the projectile is used to separate a closure disk to release stored, pressurized gases in addition to activating the gas generator. In this case, the preferred projectile facilitates the controlled separation of any closure disk used to retain pressurized, stored gases used by the . inflator in addition to the propellant gases.
