Claims
- 1. A passenger restraint system in combination with a motorized vehicle, comprising:
- an inflatable metal bladder mounted to said motorized vehicle, wherein said metal bladder has a first metal sheet joined to a second metal sheet, both said first metal sheet and said second metal sheet having a thickness of from about 0.004 inch to about 0.030 inch, wherein said inflatable metal bladder is effective to both restrain an occupant and to attenuate injury to said occupant in the event of a collision;
- a gas generator that generates a gaseous stream when actuated, said gaseous stream having a temperature of from about 600.degree. C. to about 2200.degree. C.;
- a conduit to direct said gaseous stream to said inflatable metal bladder and thereby inflate said inflatable metal bladder; and
- a sensor mounted to said motorized vehicle to actuate said gas generator.
- 2. The passenger restraint system of claim 1 wherein said first metal sheet is joined to said second metal sheet with an inflatable separation disposed there between.
- 3. The passenger restraint system of claim 2 wherein said inflatable separation is defined by a weld bead joining said first metal sheet to said second metal sheet.
- 4. The passenger restraint system of claim 2 wherein said inflatable separation is deformed by the combination of a weld bead and a folded portion of at least one of said first sheet and said second sheet.
- 5. The passenger restraint system of claim 2 wherein said first metal sheet is mounted to a surface of a door panel of said motorized vehicle.
- 6. The passenger restraint system of claim 5 wherein said inflatable separation is inflated to a pressure of from about 5 psig to about 50 psig.
- 7. The passenger restraint system of claim 2 wherein said inflatable metal bladder is mounted within a hollow body part of said motorized vehicle.
- 8. The passenger restraint system of claim 7 wherein said inflatable metal bladder is mounted within a door of said motorized vehicle.
- 9. The passenger restraint system of claim 8 wherein said inflatable separation is inflated to a pressure of from about 2000 psig to about 5000 psig.
- 10. The passenger restraint system of claim 2 wherein said inflatable metal bladder is mounted underneath a dash board of said motorized vehicle.
- 11. The passenger restraint system of claim 10 wherein said inflatable separation is inflated to a pressure of from about 20 psig to about 150 psig.
