Abstract
A gas generation device includes an elongated housing and an ignitor tube. The elongated housing defines a generant bed. The ignitor tube is disposed within the housing and extends at least substantially along the entire length of the generant bed. The ignitor tube defines an unobstructed path for ignitor gases to travel into the generant bed. The ignitor tube is constructed of a consumable material.
Claims20
A gas generation device comprising:
- an elongated housing defining a generant bed;
- and
- an ignitor tube disposed within the housing and extending at least substantially along the entire length of the generant bed, the ignitor tube defining an unobstructed path for ignitor gases to travel into the generant bed, the ignitor tube constructed of a consumable material.
A gas generation device for an inflatable airbag, the gas generation device comprising:
- a generally cylindrical housing having a maximum outside diameter;
- a generant bed defined by the housing;
- and
- an ignitor tube disposed within the housing such that the generant bed is circumferentially positioned between the ignitor tube and the housing, the ignitor tube constructed of a consumable material and extending substantially along the entire length of the generant bed, the ignitor tube defining an unobstructed path for ignitor gases to travel into the generant bed substantially along the length of the generant bed;
- wherein a ratio of a length of the ignitor tube and the maximum outside diameter of the housing is at least approximately 4:1.
