Abstract

An airbag module for a motor vehicle includes an airbag, an inflow orifice, a continuously running marginal region, a gas generator, a generator carrier having a base and emerging from an output orifice, a surface defined by the marginal region, and a continuous running wall protruding from the base. The wall has at least one first outflow orifice through which gas emerging from the gas outlet orifice of the gas generator can pass into the outside space of the airbag module. A cylindrical ring with a clearance is arranged displaceably on the wall in a movement direction running around the wall. The clearance is able to be brought into congruence with the outflow orifice as a result of a displacement of the cylindrical ring in the movement direction to open the first outflow orifice.
