    Provided is a liquid curable silicone rubber composition containing the following components of (A), (B), (C) and (D): (A) 100 parts by weight of an organopolysiloxane having one or more silicon atom-bonded alkenyl groups on average in one molecule, (B) (B-1) an organohydrogenpolysiloxane having at least three silicon atom-bonded hydrogen atoms in one molecule, wherein at least one of the hydrogen atoms is present as a siloxane unit represented by the formula of R1HSi02/2 (wherein R1 represents a non-substituted or substituted monovalent hydrocarbon group containing no aliphatic unsaturated bond) in the molecule and (B-2) a linear organohydrogenpolysiloxane having one silicon atom-bonded hydrogen atom only at each of both terminals of the molecular chain and having no aliphatic unsaturated bond(s) in a molecule, [provided that the blending amount of component (B-1) and component (B-2) is an amount such that the molar ratio of silicon atom-bonded hydrogen atoms contained in component (B-1) and component (B-2):alkenyl groups contained in component (A) ranges from (0.8:1.0) to (2.5:1.0), and the total number of silicon atom-bonded hydrogen atoms contained in component (B-2) is 70 to 100% of the total number of silicon atom-bonded hydrogen atoms contained in component (B-1) and component (B-2); provided that when the aforementioned numerical value is 100%, component (B) consists only of (B-2).] (C) a hydrosilylation reaction catalyst: an amount to cure the present composition, and (D) 0.1 to 50 parts by weight of a reinforcing silica fine powder. A coated woven fabric with a silicone rubber-coated layer formed of a cured product of this liquid curable silicone rubber composition is suitable as a coated woven fabric for use in airbags.
