Gas generator
First Claim
1. 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).

Abstract
A gas generator comprises an outflow chamber and a freeing element. The outflow chamber contains at least briefly gas under pressure, when the gas generator is activated and at least one outflow opening is arranged in a side wall of the outflow chamber. The freeing element is arranged non-displaceably in the outflow chamber and has a peripheral wall and a base wall. The peripheral wall extends along the side wall and closes at least one outflow opening before an activation of the gas generator. The base wall is connected with the peripheral wall. The freeing element is constructed so that on exceeding a predetermined gas pressure in the outflow chamber, the base wall turns inwards under partial plastic deformation of the peripheral wall and at least one hitherto concealed outflow opening is freed by the plastic deformation of the peripheral wall.
