1. An airbag device for a motor vehicle, comprising:
- an inflatable gas bag;
a gas generator for inflating the gas bag;
a valve through which gas is released out of the bag, wherein the valve includes a basic body and a moveable actuating element that can be actuated in order to open the valve; and
a triggering mechanism for actuating the actuating element by generating pressure, wherein the triggering mechanism includes a sensor-controlled, pyrotechnic unit that releases a gas in order to actuate the actuating element;
wherein the airbag device is configured so that the released gas passes into a pressure space of the valve to act directly on a pressure application surface of the actuating element;
wherein the pressure space is located in an interruption of the actuating element, the interruption being bounded on one side by an actuating-element stop and on the other side by the pressure application surface, so that the actuating element moves in response to the action of the triggering mechanism, wherein the airbag device is configured so that the movement is ended by the actuating-element stop striking against a basic-body stop.

Abstract
An airbag module for a motor vehicle comprises an inflatable gas bag; a gas generator for inflating the gas bag; a valve for letting gas out of the gas bag; a moveable actuating element for the valve, which can be actuated in order to open the valve; and a trigger mechanism which is used to actuate the actuating element by producing pressure. The trigger mechanism releases a compressed gas in order to actuate the actuating element, the gas directly acting upon a pressure attach surface of the actuating element.
