Abstract: In an assembly (20) of an elongate inflator (10) which has an outer housing (14) with outflow openings (18) spread along the circumference (U) and defining an outflow area (16) and an outflow direction, and of a clamp-type diffusor (22) enclosing the outflow area (16), the diffusor (22) includes a central receiving opening (24) into which the outer housing (14) protrudes so that the diffusor (22) circumferentially encloses an axial portion of the outer housing (14) which comprises the outflow area (16). At the inner side of the diffusor (22) delimiting the receiving opening (24) at least one bearing surface (34) and at least one gas guiding surface (30) are provided, wherein the bearing surface (34) bears directly against the outer housing (14) of the inflator (10) and the gas guiding surface (30) is radially spaced apart from the outer housing (14) while forming at least one collecting chamber (30) into which gas flowing out of the outflow area (16) is flowing.

Abstract: In an assembly group (12) consisting of a cap (14) of a diffusor of a tubular gas generator (10) and a deflector element (16), the cap (14) comprises an outflow opening for gas generated by the tubular gas generator (10) and the deflector element (16) comprises a discharge portion (34) having at least one discharge opening (42b) through which gas exits the cap (14). The deflector element (16) is inserted into the outflow opening so that the discharge portion (34) protrudes laterally outwardly through the outflow opening, projects there from the cap (14), and an edge portion of the deflector element (16) abuts on an edge of the outflow opening at an inner face of a wall of the cap (14). The discharge portion (34) of the deflector element (16) is pushed from an interior of the cap (14) through the outflow opening until the edge portion abuts on the inner face of the edge of the outflow opening, and subsequently the cap (14) is firmly fixed to the tubular gas generator (10).

Abstract: A vehicle occupant restraint device comprises a control unit and a group of at least two matched airbags (20, 24; 22, 26) for the protection of a vehicle occupant (10; 16) on a particular vehicle seat (12; 16). The control unit is arranged and the airbags (20, 24; 22, 26) are disposed and designed so that, in a collision case, the control unit differentiates between a first situation in which the vehicle occupant (10; 16) is located in a standard distance area relative to a first airbag (20; 22) and a second situation in which the vehicle occupant (10; 16) is located in a rear area which is further distant from the first airbag (20; 22) than the standard distance area. When the first situation is given, the control unit activates the first airbag (20; 22) only. In contrast, when the second situation is given, the control unit activates the first airbag (20; 22) and additionally at least a second airbag (24; 26) of the group, with the first airbag (20; 22) backing the second airbag (24; 26).
