Abstract
An airbag module for a vehicle occupant restraint system includes an airbag (22) and a gas generator (10) that is connected via at least one first outflow opening (18) to an airbag chamber (28), the airbag chamber (28) being at least partially formed by the interior of the airbag (22), an actuator unit (36) being provided on the gas generator (10) and, when the actuator unit (36) is activated, it releases a traction element (50) that causes a pressure reduction in the airbag (22), an activation of the actuator unit (36) also leading to an opening of a second outflow opening (20) in the gas generator (10), which vents generator gas to an environment without this vented gas flowing into the airbag chamber (28).Moreover, the invention relates to a method of restraining a vehicle occupant with such an airbag module.
