Abstract
A novel airbag module is described. The airbag module includes an inflatable cushion defining a mouth for receiving inflation fluid. A substantially cylindrical housing is configured to retain the inflatable cushion in a folded state. A disc-shaped inflation fluid source is attached to the housing and is in communication with the inflatable cushion. The inflation fluid source is positioned substantially within the housing and is configured to produce at least about 120 liters of inflation fluid volume. A flared retaining collar is positioned about the inflation fluid source adjacent an inner surface of the inflatable cushion to retain the inflatable cushion in communication with the inflation fluid source.
Claims29
A passenger side airbag restraint module, comprising:
- an inflatable cushion defining a circular mouth for receiving inflation fluid;
- a substantially cylindrical housing configured to retain the inflatable cushion in a folded state, the housing having a flange extending radially from a top end thereof, the flange shaped to be mounted to an instrument panel on the passenger side of a vehicle;
- an disc-shaped inflation fluid source attached to the housing and in communication with the inflatable cushion, the inflation fluid source having a plurality of openings through which inflation fluid may pass, a majority of the inflation fluid source positioned within the housing, the inflation fluid source further configured to produce at least about 120 liters of inflation fluid volume;
- and
- a retaining collar positioned about the inflation fluid source and adjacent an inner surface of the inflatable cushion to retain the inflatable cushion in communication with the inflation fluid source.
A passenger side airbag restraint module, comprising:
- an inflatable cushion defining a substantially circular mouth for receiving inflation fluid;
- a substantially cylindrical housing shaped to be mounted within a cavity in an instrument panel on the passenger side of a vehicle, the housing configured to retain the inflatable cushion when the cushion is in a folded state;
- an inflation fluid source, having a proximal end and a distal end, attached to the housing and in communication with the inflatable cushion, a majority of the inflation fluid source positioned within the housing;
- and
- a retaining collar defining an opening, the retaining collar positioned to retain the inflatable cushion in communication with the inflation fluid source.
A passenger side airbag restraint module, comprising:
- an inflatable cushion defining a circular mouth for receiving inflation fluid, the inflatable cushion shaped to be mounted within an instrument panel on the passenger side of a vehicle;
- a substantially cylindrical housing configured to retain the inflatable cushion in a folded state;
- an inflation fluid source having an attachment flange extending substantially orthogonally outward from a an outer surface of the inflation fluid source, the inflation fluid source having a proximal end and a distal end, the inflation fluid source being attached to the housing and in communication with the inflatable cushion, a majority of the inflation fluid source positioned within the housing, the inflation fluid source having a cylindrical portion with openings spaced about an outer surface of the cylindrical portion;
- and
- a retaining collar defining an opening, the retaining collar positioned about the inflation fluid source and adjacent an inner surface of the inflatable cushion to retain the inflatable cushion in communication with the inflation fluid source.
