Abstract

An airbag module for a motor vehicle is provided. The airbag module comprising a gas bag, which is inflatable by means of a gas generator for the protection of a person, and a vent opening through which gas originating from the airbag module can escape, and a device for controlling the outlet cross-section of the vent opening, which comprises at least one covering member with which the vent opening can be covered, in order to at least partly close the same, and which furthermore comprises an actuating mechanism which cooperates with the covering member, in order to vary the outlet cross-section of the vent opening. The actuating mechanism includes a gas source and an element inflatable by means of the gas source, which during inflation cooperates with the covering member such that it effects a change in the outlet cross-section of the vent opening.
