2. A vehicular safety system comprising a combination of at least one inflator and one or more inflatable restraint gel cushion(s) made from a tear resistant gel composition comprising:

(I) one or more hydrogenated controlled distribution styrene isoprene/butadiene styrene or styrene butadiene styrene block copolymer(s), and

(II) one or more selected plasticizer(s);

in combination with or without a selected amount of one or more polymer(s) or copolymer(s) selected from poly(styrene-butadiene-styrene), poly(styrene-butadiene), poly(styrene-isoprene-styrene), poly(styrene-isoprene), poly(styrene-ethylene-propylene), poly(styrene-ethylene-propylene-styrene), poly(styrene-ethylene-butylene-styrene), poly(styrene-ethylene-butylene), poly(styrene-ethylene-propylene) n , poly(styrene-ethylene-butylene) n , polystyrene, polybutylene, poly(ethylene-propylene), poly(ethylene-butylene), polypropylene, polyethylene, and metallocene catalyzed poly(ethylene-styrene), poly(ethylene-octene-1), poly(ethylene acrylic acid), and linear low density polyethylene; wherein said selected copolymer(s) is a linear, radial, branched, star-shaped, or multiarm copolymer; and n is an integer greater than one; said gel(s) having a selected gel rigidity of from about 50 gram Bloom to about 1,200 gram Bloom.

3. A vehicular safety system comprising one or more inflatable restraint gel cushion(s) of one or more shaped gel diaphragm(s) selected from one or more of a thin gel diaphragm, a thick gel diaphragm, a multiple progressive thin gel diaphragm, and a multiple progressive thick gel diaphragm; said shaped gel diaphragm(s) with or without one or more expansion control element(s), said shaped gel diaphragm(s) comprising a tear resistant gel composition comprising:

(I) one or more hydrogenated controlled distribution styrene isoprene/butadiene styrene or styrene butadiene styrene block copolymer(s), and
