Gas bag for a vehicle occupant restraint system
First Claim
1. A gas bag, in particular a side gas bag for a vehicle occupant restraint system, with a first and a second planar side wall (12, 14), connected with each other, consisting of a textile fabric with warp threads (18) and weft threads (20), which at least partially laterally delimit at least one inflatable chamber (15), at least one elongated dividing wall (22) being provided between the side walls (12, 14), the dividing wall (22) running continuously over a majority of a length (L) of the side gas bag (10) and delimiting a gas duct (24;

Abstract
A gas bag, in particular a side gas bag for a vehicle occupant restraint system has a first and a second planar side wall, connected with each other, consisting of a textile fabric with warp threads and weft threads, which at least partially delimit at lest one inflatable chamber laterally. Between the side walls at least one elongated dividing wall is provided, running continuously over a majority of the length of the side gas bag and delimiting a gas duct which directs inflowing gas into the inflatable chamber. The dividing wall is formed by threads which leave the textile fabric composite of one of the side walls in the direction of the opposite side wall and run over a predetermined length inside the side gas bag. The dividing wall has at least one overflow section with a higher gas-permeability than that of the remaining dividing wall, which forms a flow path from the gas duct to an adjoining inflatable chamber.
