Airbag having back parts with a larger surface than the front part

摘要

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.
