Abstract

This invention relates to combined heat and kinetic energy absorption in a passenger restraint system as a result of the use of a barrier contained within the passenger restraint bag. More specifically, this invention relates to the introduction of nonelastic, but independent, heat and kinetic energy absorbing bag or other barrier material within the air bag which is utilized to restrain forward motion of a passenger within a motor vehicle.

Claims

1. Inflatable restraint system comprising a source of inflating gas, an outer bag of predetermined volume when fully inflated, an independent and expandable, but inelastic, heat and kinetic energy absorbing inner bag of smaller volume than the outer bag when fully inflated independent of and located in said outer bag, means for introducing all of the inflating gas directed toward the outer bag into said inner bag to expand said inner bag, said inner bag conforming to the shape of said outer bag when said gas is introduced thereinto and of just less than the same volume as the outer bag when both are fully expanded by said gas, said inner bag being formed of nylon fabric coated with aluminized neoprene.

2. Inflatable restraint system comprising a source of inflating gas, an outer bag of predetermined volume when fully inflated, an expandable, but inelastic, kinetic energy absorbing inner bag of smaller volume than the outer bag when fully inflated independent of and located in said outer bag, heat absorbing fiber glass material included in said inner bag, means for introducing all of the inflating gas directed toward the outer bag into said inner bag to expand said inner bag, said inner bag conforming to the shape of said outer bag when said gas is introduced thereinto and of just less than the same volume as the outer bag when expanded by said gas.
