AIRBAG

摘要

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°C, with preference less or equal than 0°C, with particular preference less or equal than -20°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°C, with preference more or equal than 110°C and with particular preference more or equal than 120°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 wall parts are either joined to one another directly or joined to one another indirectly by way of an intermediate portion (7).
