An airbag comprises a textile substrate and a coating on at least a portion of the surface of the textile substrate. The coating comprises a polyurethane polymer and a phosphorous compound. The phosphorous compound can be selected from the group consisting of esters of phosphoric acid, esters of phosphonic acid, esters of phosphinic acid, and mixtures thereof. An airbag module comprises the above-described airbag, a gas generator, and a cover at least partially enclosing the airbag and gas generator. 1. An airbag comprising:(a) a textile substrate, the textile substrate having at least one surface; and (i) a polyurethane polymer; and', '(ii) a phosphorous compound selected from the group consisting of esters of phosphoric acid, esters of phosphonic acid, esters of phosphinic acid, and mixtures thereof., '(b) a coating on at least a portion of the surface of the textile substrate, the coating comprising2. The airbag of claim 1 , wherein the textile substrate is a woven fabric comprising a plurality of synthetic yarns.3. The airbag of claim 2 , wherein the synthetic yarns comprise fibers selected from the group consisting of polyamide fibers claim 2 , polyester fibers claim 2 , polyolefin fibers claim 2 , and mixtures thereof.5. The airbag of claim 1 , wherein the phosphorous compound is present in the coating in an amount of about 1 part to about 80 parts per 100 parts of the polyurethane polymer.6. The airbag of claim 5 , wherein the phosphorous compound is present in the coating in an amount of about 10 to about 60 parts per 100 parts of the polyurethane polymer.7. A method for producing an airbag claim 5 , the method comprising the step of:(a) providing a textile substrate, the textile substrate having at least one surface; (i) a liquid medium;', '(ii) a polyurethane polymer; and', '(iii) a phosphorous compound selected from the group consisting of esters of phosphoric acid, esters of phosphonic acid, esters of phosphinic acid, and mixtures thereof;, '(b) ...
