An aqueous coating film-forming composition is provided that can be coated uniformly on a silicone rubber surface without causing repelling or coating failure even when applied to the silicone rubber surface at a film thickness of 30 m or less, and forms an antifriction dry coating film that reduces friction and/or blocking of the substrate surface on the surface. The composition comprises (A) a solid lubricant, (B) a thickener, and (C) a silicone binder in the form of an oil-in-water silicone emulsion comprising (c1) an ionic emulsifier and (c2) a polyoxyethylene-polyoxypropylene copolymerized nonionic emulsifier. Water content is removed from the composition to form an antifriction dry coating film comprising 40 to 80 mass % of component (A), 0.50 to 10 mass % of component (B), 0.60 to 5 mass % of component (c2), and 5 to 49.5 mass % of component (C) (solid fraction). Applications thereof are also provided, e.g. airbag coatings.

A restraint system of a vehicle having a roof and a cabin with a seat for an occupant includes an inflator mounted to the roof of the vehicle and an airbag communicatively coupled to the inflator and inflatable to a deployed position from a stored position. The airbag comprising a main body comprising a first side that faces an upper half of an occupant, a second side that faces a lower half of the occupant, a first end coupled to the first and second sides, and a second end coupled to the first and second sides. The airbag further comprising a first tube communicatively coupled to the inflator and the main body between the first end and the second end and a second tube communicatively coupled to the inflator and the main body between the first end and the second end.
