Abstract
A gas bag for a vehicle occupant restraint system includes a wall, an inflation port configured therein, a deflection part arranged between the inflation port and a portion of the gas bag wall arranged opposite the inflation port, and a counterpiece which is arranged between the deflection part on the one hand and the inflation port as well as a portion of the gas bag wall surrounding the inflation port on the other hand. The deflection part and the counterpiece are stitched to each other such that a prechamber is formed which communicates with the interior of the gas bag by overflow ports formed between the deflection part and the counterpiece.
