ABSTRACT:
A multi-chamber airbag includes a first outer material layer, a second outer material layer, and at least one third material layer disposed between the first and second material layers. The three material layers are connected together along an edge section of the airbag. In a first partial section of the edge section only the first material layer is attached together with the third material layer and in a second partial section outboard of the first partial section only the second material layer is attached together with the third material layer. This increases the gas impermeability of the edge section.
