Abstract

An inflatable occupant restraint device includes an airbag in fluid communication with a gas generator and a diverter carried within the air bag adjacent the gas discharge openings of the gas generator to direct a portion of the gas flow away from the occupant to be restrained.

Claims

1. An inflatable occupant restraint device for an automotive vehicle for restraining the movement of an occupant of the vehicle with respect to the device comprising:

a gas generating device mounted on the vehicle including means for effecting the flow of gas and having gas discharge openings arranged to direct said gas flow toward said occupant;

a flexible bag fixedly secured to said gas generating device and having interior surfaces in fluid communication with said gas discharge openings for effecting inflation of said flexible bag; and

a fluid permeable diverter carried within said flexible bag adjacent said gas discharge openings and operative to deflect a portion of said gas flow away from said occupant.

2. An inflatable occupant restraint device as defined in claim 1, wherein said diverter is a flexible member fixedly secured to said flexible bag.

3. An inflatable occupant restraint device as defined in claim 2, wherein said flexible bag and said diverter are each fabricated from a fluid permeable fabric.

4. An inflatable occupant restraint device as defined in claim 3, wherein said diverter is sewn to said flexible bag.

5. An inflatable occupant restraint device as defined in claim 1, wherein said diverter includes means for deflecting said gas flow laterally outwardly with respect to said occupant.

6. An inflatable occupant restraint device as defined in claim 5, wherein said diverter further includes means for deflecting said gas flow vertically with respect to said occupant.

7. An inflatable occupant restraint device as defined in claim 2, wherein said diverter is a U-shaped sleeve.

8. An inflatable occupant restraint device for an automotive vehicle for restraining the movement of an occupant of the vehicle with respect to the device comprising:

a gas generating device mounted on the vehicle in juxtaposition with said occupant, including means for effecting the flow of gas and having gas discharge openings arranged to direct said gas flow toward said occupant;

a flexible bag fixedly secured to said gas generating device and having interior surfaces in fluid communication with said discharge openings for effecting inflation of said flexible bag; and

a diverter carried within said flexible bag in juxtaposition with said occupant adjacent said gas discharge openings and including fluid permeable means operative to deflect a portion of said gas flow away from said occupant and to direct a smaller portion of said gas flow toward said occupant.

9. An inflatable occupant restraint device as defined in claim 8, wherein said diverter is a flexible member fixedly secured to said flexible bag.

10. An inflatable occupant restraint device as defined in claim 9, wherein said flexible bag and said diverter are each fabricated from a fluid permeable fabric.

11. An inflatable occupant restraint device as defined in claim 10, wherein said diverter is sewn to said flexible bag.

12. An inflatable occupant restraint device as defined in claim 8, wherein said diverter includes means for deflecting said gas flow laterally outwardly with respect to said occupant.

13. An inflatable occupant restraint device as defined in claim 12, wherein said diverter further includes means for deflecting said gas flow vertically with respect to said occupant.

14. An inflatable occupant restraint device as defined in claim 9, wherein said diverter is a U-shaped sleeve.

15. An inflatable occupant restraint device as defined in claim 10, wherein said diverter is a U-shaped sleeve of fluid permeable fabric.

16. An inflatable occupant restraint device for an automotive vehicle for restraining the movement of an occupant of the vehicle with respect to the device comprising:

a gas generating device mounted on the vehicle in juxtaposition with said occupant, including means for effecting the flow of gas and having gas discharge openings arranged to direct said gas flow toward said occupant;

a flexible bag fixedly secured to said gas generating device and having interior surfaces in fluid communication with said discharge openings for effecting inflation of said flexible gag; and

a fluid permeable diverter carried within said flexible bag in juxtaposition with said occupant adjacent said gas discharge openings and including means operative to deflect a portion of said gas flow away from said occupant and to direct a smaller portion of said gas flow toward said occupant.

17. An inflatable occupant restraint device for an automotive vehicle for restraining the forward movement of an occupant of the vehicle comprising:

an elongated gas generating device mounted on the vehicle for lateral extension across the vehicle in juxtaposition with said occupant, including means for effecting the flow of gas and having laterally spaced gas discharge openings arranged to direct said gas flow toward said occupant;

a flexible bag fixedly secured to said gas generating device and having interior surfaces in fluid communication with said discharge openings for effecting inflation of said flexible gag; and

a fluid permeable diverter carried within said flexible bag in juxtaposition with said occupant adjacent and overlying all of said gas discharge openings and including means operative to deflect a portion of said gas flow away from said occupant and to direct a smaller portion of said gas flow toward said occupant.
