Abstract

The invention relates to an airbag with wall parts (1, 2), which comprise or consist of a laminated material, the laminated material comprising: (a) a backing layer (3), in particular comprising a gas-permeable textile sheet-like structure, preferably a layer of woven or knitted fabric, and (b) an at least two-layered, in particular co-extruded polymer film (4), a first polymer layer (5), facing towards the backing layer, having a glass transition temperature Tg1 of less or equal than 10.degree. C., with preference less or equal than 0.degree. C., with particular preference less or equal than -20.degree. C., and a second polymer layer (6), facing away from the backing layer, having a storage modulus according to the torsion pendulum test as specified by DIN 53 445 of more or equal than 1 MPa at more or equal than 90.degree. C., with preference more or equal than 110.degree. C. and with particular preference more or equal than 120.degree. C. The wall parts are joined together here in at least one joining region, in particular only in edge regions of the airbag, in such a way that the second polymer layers of the wail parts are either joined to one another directly or joined to one another indirectly by way of an intermediate portion (7).
