Abstract
An airbag device for a vehicle includes an airbag and a sensor element located on the side of the airbag which moves towards the vehicle occupant. The sensor element is formed of sensor strips which transmit sensed pressure changes in the form of a sensor signal to a control device. The amount of gas supplied by a filling device can be controlled in response to the sensor signal. The sensor element has resistor elements forming a matrix-type grid of spaced apart contact regions of the resistor elements. An electric resistance in a contact region of two resistor elements is dependent on the force or pressure load of the contact region. A voltage can be applied to least one of the resistor elements at least in one of the contact regions via an electrically conductive element which is in electrical contact with a resistor element at the contact region.
