Gas generating system
View Patent ↗A gas generating system includes a housing structured to form a booster tube mounting structure therein, and a booster tube engaged with the mounting structure so as to form a gas-tight seal therebetween and so as to be movable with respect to the mounting structure, and such that the seal is maintained during movement of the tube with respect to the mounting structure, while the tube is engaged with the mounting structure.
1. A gas generating system comprising:
housing structured to form a booster tube mounting structure therein; and
a booster tube engaged with the mounting structure so as to form a gas-tight seal therebetween and so as to be movable with respect to the mounting structure,
and such that the seal is maintained during movement of the tube with respect to the mounting structure, while the tube is engaged with the mounting structure.
2. The system of claim 1 wherein the housing is an outermost housing of the gas generating system, wherein the housing has a base portion and a wall extending from a peripheral edge of the base portion, and wherein the mounting structure is formed into the base portion.
3. The system of claim 1 wherein the mounting structure is structured so as to extend into an open end of the booster tube so as to form a gas-tight seal between the mounting structure and the booster tube.
4. The system of claim 1 wherein the mounting structure is in direct contact with an auto-ignition material positioned within the booster tube when the booster tube is engaged with the mounting structure.
5. An airbag system including a gas generating system in accordance with claim 1 .
6. A vehicle occupant protection system including a gas generating system in accordance with claim 1 .
7. A gas generating system comprising:
a housing structured to permit expansion thereof responsive to elevated pressures within the housing;
a booster tube mounting structure formed by a portion of the housing; and
a booster tube having a first end structured and engaged with the mounting structure so as to form and maintain a gas-tight seal between the tube and the mounting structure during expansion of the housing, and a second end structured and engaged with another portion of the gas generating system so as to form and maintain a gas-tight seal between the tube and the other portion of the gas generating system during expansion of the housing.
8. The system of claim 7 wherein the mounting structure is in direct contact with an auto-ignition material positioned within the booster tube when the booster tube is engaged with the mounting structure.
9. An airbag system including a gas generating system in accordance with claim 7 .
10. A vehicle occupant protection system including a gas generating system in accordance with claim 7 .
11. A gas generating system comprising:
a housing structured to permit expansion thereof responsive to elevated pressures within the housing;
a booster tube mounting structure formed by a portion of the housing; and
a booster tube having a first end, a second end opposite the first end, a wall extending between the first and second ends, and at least one gas discharge aperture formed in the wall to enable fluid communication between an interior of the tube and an exterior of the tube,
each of the first and second ends being structured and engaged with an associated one of the mounting structure and another portion of the gas generating system so as to form a gas-tight seal therebetween prior to expansion of the housing,
at least one of the first and second ends being structured and engaged with the associated one of the mounting structure and other portion of the gas generating system so as to maintain a gas-tight seal between the tube and the mounting structure during expansion of the housing.
12. The system of claim 11 further comprising a plurality of gas discharge apertures formed in the tube wall to enable fluid communication between an interior of the tube and an exterior of the tube 1 .
13. The system of claim 11 wherein the other one of the first and second ends is structured and engaged with an associated one of the mounting structure and another portion of the gas generating system so as to permit a degree of spacing between the other one of the first and second ends and the associated one of the mounting structure and other portion of the gas generating system during expansion of the housing.
14. The system of claim 11 wherein the mounting structure is in direct contact with an auto-ignition material positioned within the booster tube when the booster tube is mounted on the mounting structure.
15. An airbag system including a gas generating system in accordance with claim 11 .
16. A vehicle occupant protection system including a gas generating system in accordance with claim 11 .
