Inflatable restraint system for automobile

摘要

The restraint system has a gas bag inflated by a gas generator in the event of a collision. The gas generator has a series of plates (64,66) of a gas-generating material arranged one after the other along a common longitudinal axis contained within a filter fitted into a rigid housing attached to the vehicle dashboard. The plates (64,66) have aligned spaced bores (112,134) for ensuring rapid uniform combustion to provide a large gas vol. within a short time.The ignition system (52) for the gas generator uses an ignition material ((96) ignited by an electrical current supplied by a collision detector, in turn activating a pyrotechnic material (98) to provide a hot gas flow passed through the bores (112,134,126) in the plates (64,66)
