Abstract
The invention relates to an inflatable airbag for vehicles. The airbag comprises at least one seam interconnecting the fabric layers of the airbag, and an inner gas-impermeable bag. The invention likewise relates to a method of manufacturing an inflatable airbag comprising fabric layers. A gas-impermeable bag is sewn in position between the fabric layers. Alternatively, two joined-together gas-impermeable layers form the gas-impermeable bag, which gas-impermeable layers are sewn in position between the two fabric layers.
