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 compressed gas in order to actuate the actuating element;
wherein the device is configured so that the released compressed gas passes into a pressure space of the basic body of the valve to act directly on a pressure application surface of the actuating element;
wherein the pressure application surface of the actuating element forms at least part of a boundary wall of the pressure space.

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.

7. An airbag module comprising:
an inflatable gas bag;
a gas generator for inflating the gas bag;
a valve for allowing gas to escape out of the gas bag;
a moveable actuating element of the valve, which can be actuated in order to open the valve; and
a triggering mechanism for actuating the actuating element, wherein, in response to a sensed condition, the triggering mechanism releases a compressed gas which impacts the actuating element thereby causing the actuating element to move.- View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
