Abstract: An airbag for vehicle-passenger protection devices that inflates rapidly in response to pyrotechnically generated gases and optionally to gases released from a compressed-gas cylinder is made at least to some extent of a textile or knit with a surface that carbonizes when exposed to hot gases. The carbonizing material also improves the airbag's resistance to total combustion by at least 20 percent without additional expense.
