Abstract: A method coats a substrate with an aluminum-doped zinc oxide. The method includes generating a nucleation coating between 5 nm and 400 nm thick and having zinc oxide or doped zinc oxide, in particular aluminum-doped zinc oxide, on a surface of a substrate by atomizing a solid target. A quasi-epitaxially propagating top coating is generated and contains an aluminum-doped zinc oxide on the nucleation coating and the top coating is wet chemically etched.

Abstract: An airbag has a front part facing a vehicle occupant and from two back parts facing away from the vehicle occupant. The two back parts have a larger surface than the front part. The back parts each have a first portion which is dimensioned in such a way that the two first portions of the back parts jointly correspond to the front part in terms of shape and size. The two back parts are connected along the free edges of their first portions to the front part along the outer circumference of the latter. The back parts have second portions that extend essentially transversely to the front part and are connected to one another along their outer edges. The connection of the second portions of the back parts is interrupted at least in one portion to form a gas inlet orifice.
