ABSTRACT:
A gas generator for inflatable vehicle safety bags comprises a housing defining three independent chambers each containing a charge of gas generating agent in a sealed wrapper surrounding an electrical ignition squib, and layers of heat absorbing wire gauze, a porous plate, and sintered filter sheets overlying the charge. The open top of each chamber is covered by an apertured diffuser, and an apertured deflector plate is secured to the housing above the diffusers. Generated gases passing through the apertures in the deflector plate inflate a relatively small inner knee bag, and laterally diverted gases inflate a larger outer torso bag surrounding the knee bag.
The inflation impact may be minimized by delaying the ignition of one or more chambers relative to the other(s), and by igniting only selected chambers in response to low speed collisions.
