摘要：
A gas bag for a vehicle occupant restraint device has a vent opening. A non-elastic thread is arranged on the outer surface of the gas bag (1) forming a loop (4) around the vent opening (2). Each end of the thread is attached to a stretchable surface portion of the gas bag. The vent opening has a flow cross-section that is able to be reduced in proportion to an elastic expansion of the gas bag (1) as a result of internal pressure which is generated when a vehicle occupant plunges into the inflated gas bag.
