The invention relates to an airbag () for unfolding between a vehicle part () and a vehicle occupant (), comprising an impact wall () which, in the installed and unfolded state of the airbag (), faces a vehicle occupant () and a circumferential wall () which is connected to the impact wall () and, in the installed and unfolded state of the airbag (), extends between the impact wall () and the vehicle part (), wherein the circumferential wall () is made with multiple layers, at least in some sections, and forms at least one annular tube () which delimits an annular inflatable first airbag volume (V), and wherein a radially inner layer () of the circumferential wall (), together with the impact wall (), delimits an inflatable second airbag volume (V) that is separate from the first airbag volume (V). The invention further relates to an airbag module () having such an airbag ().

Airbag and airbag module for a motor vehicle having such an airbag

The invention relates to an airbag for a vehicle occupant restraint system, comprising an airbag panel () defining an inflatable airbag volume as well as including a front panel portion () and a rear panel portion (), a tether () extending in the interior of the airbag () across the inflatable airbag volume, a discharge orifice () which is formed in the rear panel portion () of the airbag panel (), as well as a first closing tab () and a second closing tab () for closing the discharge orifice (), wherein the tether () extends from a first tether end () tightly connected to the front panel portion () in the direction of the discharge orifice () to an opposite second tether end (), wherein the first closing tab () extends from a first tab end () tightly connected to the rear panel portion () to a second tab end () tightly connected to the second tether end (), wherein the second closing tab () is fastened on the rear panel portion () adjacent to the discharge orifice (), and wherein the two closing tabs () are coupled by a connection releasable when a vehicle occupant () impacts on the inflated airbag ().

Airbag for vehicle occupant restraint system

The invention relates to an airbag package () for an occupant restraint system of an automotive vehicle comprising a folded airbag () and clearances formed between the material of the airbag, wherein the airbag package () has a real package volume Vcomposed of the airbag volume Vof the airbag () and the clearance volume Vof the clearances. The invention excels by the fact that the ratio V/Vbetween the package volume Vand the airbag volume Vis at most 3.2. The invention further relates to an occupant restraint system comprising such airbag package and to a method of manufacturing an airbag package.
