Abstract: Substitute materials are increasingly proposed for contact pieces in low-voltage switches, which until now frequently consisted of silver-nickel. In the case of such a substitute material which, besides silver, contains at least iron oxide (Fe.sub.2 O.sub.3 /Fe.sub.3 O.sub.4) and zirconium oxide (ZrO.sub.2) as active components, the making capacity with regard to the critical welding current is improved by an addition of a further oxide of the sixth subgroup of the Periodic System and/or of a mixed oxide that consists of iron oxide and the oxide of an element of the sixth subgroup of the Periodic System. In this connection, the further additive is, in particular, ferro-wolframate (FeWO.sub.4).

Abstract: Collision-protection devices for vehicle passengers, are disclosed which include a gas cushion which is connected to a gas generator and inflates under sensor control in the event of an accident and hence protects the body of a vehicle passenger from a collision causing injury, e.g., against the instrument panel or windscreen. The gas cushion has, in this instance, one or more escape openings. According to the invention, the escape opening points towards an open cover flap when the gas cushion is inflated, which cover flap, in the closed state, covers the folded-up gas cushion. Only once a predetermined pressure has been exceeded does the cover flap free the escape opening to enable gas to be discharged in an escape flow distributed over an area of the gas cushion surface.
