Abstract

A restraint device for vehicle occupants, in particular for the lateral restraining of the occupant, comprising an inflatable gas bag (10) and a tensioning device which is connected with the vehicle, engages the gas bag, pulls the gas bag into an intended position on inflation, and holds the gas bag in this position, is characterized in that the tensioning device has at least one inflatable tightening means (20) which shortens in the pulling direction by the inflation and thereby exerts a tensile force on the gas bag.
