Zusammenfassung:	A heat shield is generally provided, along with methods of making the heat shield and its use in a vehicle safety device (e.g., an airbag). In one embodiment, the heat shield includes a base substrate (e.g., a nonwoven fabric, a woven fabric, or a film); a heat resistant coating on the base substrate; and a first point-bonded sheet laminated to the heat resistant coating such that the first point-bonded sheet forms an outer surface of the heat shield with the heat resistant coating positioned between the first point-bonded sheet and the base substrate. The heat resistant coating generally comprises particles of an inorganic mineral (e.g., vermiculite, mica, or a combination thereof) dispersed within a film-forming binder (e.g., an acrylic resin, a styrene-butadiene rubber, a polyvinyl alcohol, an ethyl vinyl acetate resin, a phenolic resin, or a combination thereof).
