ABSTRACT:
A device is provided for ignition of a pyrotechnic or hybrid inflator for use in motor vehicles by the input of energy provided by a laser source. The laser energy is conducted through an optical fibre and an optical window in the inflator housing where the ignition of a propellant initiator is triggered. This apparatus eliminates the potential for ignition of the inflator by radio frequency energy or static electricity acting on the electrical squib which is standardly used to ignite an inflator. This design further simplifies the igniter assembly for use in an inflator.
