Abstract

A gas bag for a vehicle occupant restraint system comprises an inflation opening and a fabric piece arranged in the interior of the gas bag opposite the inflation opening and defining a volume for compressed gas introduced into the gas bag through the inflation opening. The fabric piece forms at least one outflow opening for the compressed gas. The outflow opening defines a gas exit area affected by the compressed gas flowing through the outflow opening, and comprising at least one limiting strap arranged in the interior of the gas bag but outside of the gas exit area.
