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).
