Abstract
A vehicle occupant restraint system comprises a gas supply means which has an outer housing with at least two outlet openings. The restraint system further comprises at least two inflatable elements to which different outlet openings are associated and which are filled in parallel via the associated outlet openings. The outlet openings are designed such that during inflation of the elements gas flow rates through the individual outlet openings to the inflatable elements are different.
