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.
Claims4
A multi-chamber airbag comprising a first outer material layer, a second outer material layer, and a third material layer disposed between the first and second material layers, the three material layers defining multiple chambers of the airbag and a peripheral edge section outboard of the multiple chambers, wherein the three material layers extend inward from an outermost end of the peripheral edge section toward the multiple chambers, the peripheral edge section including a first partial section extending inward from the outermost end of the peripheral edge section to a second partial section inboard of the first partial section and outboard of the multiple chambers, only the first and third material layers being woven together in the first partial section of the peripheral edge section wherein warp threads of the first and third material layers loop around weft threads of the first and third material layers, only the second and third material layers being woven together in the second partial section of the peripheral edge section wherein warp threads of the second and third material layers loop around weft threads of the second and third material layers.
