First Claim
Patent Images
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°
C. to about 2200°
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.

Abstract
There is disclosed a metallic bladder that is inflated by a gaseous stream generated by a gas generator. The inflatable metallic bladder is useful as a side impact air bag for motorized vehicles. The heat dissipating capability of the metallic bladder permits the use of energetic chemical compositions that generate a high temperature gas and very rapidly inflate the metallic bladder. The heat conducted by the gas is dissipated by the metallic bladder avoiding harm to occupants.
