An airbag of a vehicle occupant restraint system has an actively releasable tether element () disposed in an interior () of the airbag () which is connected, at an airbag-side fixation (), permanently to the airbag () in the region of a contact zone () for the occupant, and which comprises a detachable fixing point () for the release. The airbag () can take up a smaller first filled volume (V) in which the tether element () and the detachable fixing point () are not released, and a larger second filled volume (V) in which the tether element () is released at the actively detachable fixing point (). In addition to the tether element (), a tether element restrainer () disposed in the interior () of the airbag () is provided which acts upon a point of action () on a vehicle-side portion () of the tether element () distant from the airbag-side permanent fixation () of the tether element () and which is permanently fixed to a coupling point () distant from the contact zone () so that the vehicle-side portion () of the released tether element () remains connected fixedly to the vehicle via the tether element restrainer ().

Airbag of a vehicle occupant restraint system

A force-limiting device, especially for a seat belt system () in a vehicle, has a force transducer () interacting with webbing () for which a normal webbing path is provided. The force transducer () includes a webbing track () that in a non-force-limiting position extends in parallel to the normal webbing path and in a force-limiting position extends inclined relative to the normal webbing path so that the force transducer () in the force-limiting position sets a predetermined extension force (F) required to move the webbing () vis-&#xe0;-vis the force transducer () in a direction of belt extension (R).

Force-limiting device and seat belt system

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

Vehicle occupant restraint device and method for operating a vehicle occupant restraint device

An air bag module () includes an air bag () having a deflated condition and an inflated condition and a structure () for supporting the air bag. A first tether () has a first end connected to the structure via an actuatable fastener () and an opposite second end connected to the air bag (). A second tether () having a first end secured to the first tether () by a releasable connection () at a location between the first and second ends of the first tether. The second tether has a second end connected to a deployable portion of the air bag ().
