  • Patent number: 6283499
    Abstract: The present invention relates to an inflatable occupant restraint device having an inflator, an outer bag disposed around the inflator to allow the outer bag to be filled with gas produced by the inflator, an inner bag, disposed in between the outer bag and the inflator, wherein the inner bag is made of a flexible material having at least one flow outlet in the flexible material altering the flow of gas produced by the inflator. The inner bag protects the outer bag from hot gases and particles emanating from the inflator. The inner bag may also have a pattern of stitched seams forming gas flow outlets to impart a desired flow pattern to the inflating gases.

  • Patent number: 5845928
    Abstract: An inflatable cushion assembly for use with an inflator comprises an inflatable cushion having an inner surface, outer surface, and at least one protrusion extending from one of the inner or outer surfaces. The inflatable cushion defines an opening between the inner surface and the outer surface for receiving the inflator. An attachment member contacts the one of the inner or outer surfaces adjacent the opening and includes a groove for receiving the protrusion, the attachment member securing the inflator within the opening.

  • Patent number: 5607182
    Abstract: An apparatus and method for making a low cost, self-venting, inflatable protective cushion of simple and structurally efficient design with a shape and construction that optimizes the cushion's ability to withstand inflation pressures and impact when deployed which includes a sheet defined by at least one fold line and a plurality of flap portions, each flap portion having a base edge corresponding to a fold line and at least two side edges each extending outwardly from a base edge and ultimately converging to meet each other, the flap portions being folded at the fold line(s) and being joined at corresponding side edges to define an inflatable chamber. The inflatable protective cushion and method for making same may further include a lightweight, low permeability, fabric that optimizes the cushion's ability to withstand inflation pressures and impact when deployed and minimizes the packed volume of the cushion when stored.
