Patent ID: 7240916

Claim:
A gas generator, comprising a housing ( 12 ), which has outflow openings ( 22 , 28 ) for outflowing gas, and at least one destructible insulation foil ( 24 ) which in a non-activated state of said gas generator ( 10 ) closes at least one of said outflow openings ( 22 ) so as to be moisture-tight, said insulation foil ( 24 ) having a varying thickness, wherein said varying thickness is provided by said foil ( 24 ) comprising a base layer ( 32 ) and at least one thermally insulating foil layer ( 34 ) with a varying thickness, which has a distinctly lower thermal conductivity than said base layer ( 32 ) and lies over said base layer ( 32 ) on a side of said insulation foil ( 24 ) which faces a gas flow.
