The invention relates to a diffuser (10) for a gas generator (50), comprising a substantially tubular main body (11) having a longitudinal axis, a baffle cap (12), which is axially connected to the main body (11), on a first end (13) of the diffuser (10) and a connection apparatus formed on a second end (14) of the diffuser (10) opposite the first end (13), wherein at least one outflow opening (21, 22) is formed in an outer wall of the tubular main body (11) such that gas can flow out of the diffuser (10) from the interior of the diffuser (10), substantially parallel to the longitudinal axis (16), in the direction of the first (13) and second (14) end, the baffle cap (12) having no outflow opening. The invention furthermore relates to a gas generator having such a diffuser, an airbag module which has such a gas generator, and to a method for producing the diffuser.

DEFLECTOR FOR A DIFFUSER OF A GAS GENERATOR, DIFFUSER-DEFLECTOR ASSEMBLY HAVING SUCH A DEFLECTOR, GAS GENERATOR HAVING SUCH A DIFFUSER-DEFLECTOR ASSEMBLY, PRODUCTION METHOD AND INSTALLATION METHOD
The invention relates to a deflector (20) for a diffuser (10) of a gas generator (50), in particular for a tubular gas generator (50) of an airbag module, having a substantially tubular main deflector body (21) and a gas discharge device (22) associated therewith, the gas discharge device (22) having a substantially rectangular area and two outflow regions (23, 24) on opposing side walls (25, 26), so that a gas can flow outwards from the interior of the gas discharge device (22) substantially in opposing directions along the longitudinal axis (16) of the tubular main deflector body (21). Furthermore, the invention relates to a diffuser-deflector assembly of a gas generator having such a deflector, a gas generator having such a diffuser-deflector assembly and an airbag module which has such a gas generator. Furthermore, the invention discloses a method for producing such a deflector and a method for installing such a deflector on a diffuser of a gas generator.

ASSEMBLY OF A COVERING CAP OF A TUBULAR GAS GENERATOR AND A DEFLECTOR ELEMENT, TUBULAR GAS GENERATOR AND METHOD FOR PRODUCING A TUBULAR GAS GENERATOR
The invention relates to an assembly (10) of a covering cap (14) of a tubular gas generator (12) and a deflector element (16), which diverts gas flowing out of at least one outflow opening (28) of the covering cap (14) to at least one discharge opening (34) of the deflector element (16), with a deflecting surface (30) of the deflector element (16) arranged radially outwards from the outflow opening (28). At least two fastening arms (40) of the deflector element (16) extend through the outflow opening (28) and engage internally behind an edge defining the outflow opening (28) in a positively locking connection to the covering cap (14). The covering cap (14) is firmly fixed to an axial end of the tubular gas generator. Next, the deflector element (16) is pushed out with its fastening arms (40) from an outer face of the covering cap (14) through the outflow opening (28), the fastening arms (40) participating in a positively locking connection to the edge of the outflow opening (28), which firmly fixes the deflector element (16) on the covering cap (14).

Igniter for a gas generator and method for producing an igniter
An igniter for a gas generator comprises a pole body (14) having at least one connection pin (16, 18), a retaining ring (20) and an insulation ring (22), wherein the insulation ring (22) spaces apart the at least one connection pin (16, 18) from the retaining ring (20) and electrically insulates it relative to the same. The retaining ring (20) consists of a metal and the insulation ring (22) consists of a plastic. In order to produce an igniter (10) for a gas generator at least one connection pin (16, 18), a retaining ring (20) and an insulation ring (22) are provided, the connection pin (16, 18), the insulation ring (22) and the retaining ring (20) are fitted inside one another in such a way that the connection pin (16, 18) is surrounded by the insulation ring (22) and the insulation ring (22) is surrounded by the retaining ring (20), and the retaining ring (20), the insulation ring (22) and the connection pin (16, 18) are compressed in a compression step in which at least the retaining ring (20) is deformed and the retaining ring (20), the insulation ring (22) and the connection pin (16, 18) are connected to one another securely and without play.
