Patent ID: 6886338

Claim:
A gas generator comprising: an outflow chamber ( 14 ) and a freeing element ( 24 ), said outflow chamber ( 14 ) containing at least briefly gas under pressure, when said gas generator ( 10 ) is activated and at least one outflow opening ( 20 ) being arranged in a side wall ( 18 ) of said outflow chamber ( 14 ), said freeing element ( 24 ) being arranged non-displaceably in said outflow chamber ( 14 ), said freeing element ( 24 ) having a peripheral wall ( 26 ) and a base wall ( 28 ), said peripheral wall ( 26 ) extending along said side wall ( 18 ), closing at least one outflow opening ( 20 ) before an activation of said gas generator ( 10 ), and circumscribing an interior of said feeing element ( 24 ), said base wall ( 28 ) being connected with said peripheral wall ( 26 ) and said freeing element ( 24 ) being constructed so that on exceeding a predetermined gas pressure (p) in said outflow chamber ( 14 ), said base wall ( 28 ) turns inwards and is moved within or into said interior of said freeing element ( 24 ) under partial plastic deformation of said peripheral wall ( 26 ) and at least one hitherto concealed outflow opening ( 20 ) is freed by said plastic deformation of said peripheral wall ( 26 ).
