Abstract
An occupant protection system includes an airbag with inflator that directs a projectile into a burst disk. As the burst disk ruptures, high pressure gas releases into the airbag for inflating the airbag.
Claims20
An inflator for inflating an airbag, comprising:
- a bottle configured to contain a high pressure gas, wherein the bottle includes an outlet located at one end of the bottle, and wherein the outlet is sealed by a burst disk;
- an initiator connected to the bottle and configured to contain a propellant gas;
- a nozzle located in the bottle and sealed by a projectile, wherein the nozzle is configured to receive propellant gas from the initiator;
- wherein the initiator and nozzle are configured so that the propellant gas ignites and passes into the nozzle causing the projectile to be directed away from the nozzle toward the burst disk;
- and
- wherein the burst disk is configured so that when the projectile contacts the burst disk, the outlet is unsealed and the high pressure gas is released into the airbag.

An airbag module for use in a passenger vehicle, comprising:
- an inflatable airbag;
- an adapter to which the airbag is secured;
- a bottle connected to the adapter and configured to contain a high pressure gas;
- a burst disk connected to the adapter and positioned to seal the bottle and separate the high pressure gas from the airbag;
- an initiator containing a propellant and being connected to the bottle;
- and
- a projectile positioned so that propellant from the initiator propels the projectile towards the burst disk;
- wherein the burst disk is configured so that when the projectile contacts the burst disk, the burst disk ruptures and the high pressure gas is released into the airbag.
