A gas generator, comprising a first and a second combustion chamber, each of which is associated with a propellant charge and an igniter, an outflow chamber with inflow-and outflow openings, arranged between the combustion chambers, and a partition plate dividing the outflow chamber into two partial chambers is provided. An edge region of the partition plate lies at least partially against a boundary of the outflow chamber. Each partial chamber is associated with one of the combustion chambers. A central section of the partition plate surrounded by the edge region has a geometry deviating from a plane and has at least one projection which is directed into one of the partial chambers.

What is claimed is: 1. A gas generator, comprising: a first and a second combustion chamber (14, 16), each of which is associated with a propellant charge (20) and an igniter (18), an outflow chamber (22) with inflow-and outflow openings (28, 29, 24), arranged between said combustion chambers (14,
What is claimed is: 1. A gas generator, comprising: a first and a second combustion chamber (14, 16), each of which is associated with a propellant charge (20) and an igniter (18), an outflow chamber (22) with inflow-and outflow openings (28, 29, 24), arranged between said combustion chambers (14, 16), and a partition plate (30) dividing said outflow chamber (22) into two partial chambers (32, 34), an edge region (38) of said partition plate lying at least partially against a boundary (12) of said outflow chamber (22), each partial chamber (32, 34) being associated with one of said combustion chambers (14, 16), characterized in that a central section (36) of said partition plate (30) surrounded by said edge region (38) has a geometry deviating from a plane (E) and has at least one projection (40, 42, 44) which is directed into one of said partial chambers (32, 34). 2. The gas generator according to claim 1, wherein as a result of a shape of said partition plate (30) clearance volumes (45) are formed in said outflow chamber (22), in which particles settle, when a gas stream flows through said outflow chamber (22). 3. The gas generator according to claim 1, wherein said partition plate (30) separates said two partial chambers (32, 34) completely from each other with regard to flow. 4. The gas generator according to claim 1, wherein each partial chamber (32, 34) is delimited from its associated combustion chamber (14, 16) by a wall (26, 27) having at least one inflow opening (28, 29), said partition plate (30) resting against said walls (26, 27). 5. The gas generator according to claim 1, wherein each partial chamber (32, 34) is delimited from its associated combustion chamber (14, 16) by a wall (26, 27) having at least one inflow opening (28, 29), said partition plate (30), viewed from each partial chamber (32, 34), having at least one indentation (39, 41), and said partition plate (30) being arranged so that an indentation (39, 41) lies opposite said inflow opening (28, 29) in each wall (26, 27). 6. The gas generator according to claim 4, wherein at least one inflow opening (28) in said wall (26) of said first combustion chamber (14) is arranged staggered with respect to at least one inflow opening (29) in said wall (27) of said second combustion chamber (16). 7. The gas generator according to claim 1, wherein a filter (46) is arranged in a region of said outflow openings (24). 8. A gas generator comprising: a tubular housing (112), in which a combustion chamber (114) containing a propellant charge (120), and an outflow chamber (122; 122') are arranged axially one behind the other, the outflow chamber (122; 122') having at least one outflow opening (124), through which gas leaves the gas generator (100; 100'), a clearance volume (150; 150') being provided in axial direction after said outflow chamber (122; 122'), the clearance volume (150; 150') being separated from said outflow chamber (122; 122') except for at least one through-flow opening (152; 152'), said clearance volume (150; 150') being connected with regard to flow only with said outflow chamber (122; 122'). 9. The gas generator according to claim 8, wherein said clearance volume (150; 150') is separated from said outflow chamber (122; 122') by a partition plate (160; 160'), which has said through-flow opening (152; 152').
