Abstract: The present invention relates to a weld-on fastener for an electrical contact with a weld nut (1) which, on its topside has an electric contact face (9) and, on its bottom side, has an annular axial projection (6) which surrounds a cavity (4) of a pre-determinable depth (T), and with a screw (3) screwed into the weld nut (1), which screw (3) also has an electric contact face (9), a spacer ring (2) being clamped between the contact faces (9). The spacer ring (2) preferably has a thickness (D) which is approximately equal to the depth (T) of the cavity (4). When the spacer ring (2) is clamped in, the screw (3) ends approximately flush with the end of the internal thread (12) of the weld nut (1). This combination is distinctive in that it has only a low overall height, no metal scabs reach the thread (12) during welding-on, the contact faces (9) are protected during assembly and the welded connection can absorb high torques even when welding onto thin work pieces (7).

Abstract: A method for triggering a gas generator for an air bag in a motor vehicle having acceleration sensors, air bags, and gas generators uses an air bag control unit for evaluating an impact. Evaluation of the impact takes place by using the signals of the acceleration sensors for triggering a gas generator. The gas generator has a triggerable valve which can be controlled into at least two conditions with a different passage cross-section. The air bag control unit controls the gas generator as a function of the seriousness of an accident such that the position of the valve of the gas generator alternates several times successively between two conditions in order to adapt the inflating operation to the collision.
