Abstract: Thermoplastic polyurethanes comprise segments A formed of a high molecular weight diol, segments B formed of at least one low molecular weight diol selected from 1,4-bis(hydroxyethoxy)benzene and 1,3-propanediol, and segments C formed of a polyisocyanate. These segments A, B and C are bonded together in a linear form by urethane bonds. The segments B account for 1 to 30 wt. % in the thermoplastic polyurethane. These thermoplastic polyurethanes are characterized in that they have high impact resilience and also in that their impact resilience does not drop much in a low temperature range, in other words, their impact resilience does not vary much depending on changes in outdoor temperature.

Abstract: A base cloth for an air bag is obtained by forming a film of a silicone modified thermoplastic polyurethane resin having a polysiloxane segment on a surface of a woven fabric, and the air bag is formed of the base cloth. Since an organic solvent is not used when the resin is prepared, its workability is superior, the resin is safe for the human body. Also, the air bag can be quickly developed in a wide range from an extremely low temperature to a high temperature, and there is no problem of adhesion or sticking. Thus, the air bag having a stable performance and the base cloth for the air bag are provided.

Abstract: An air bag made of thermoplastic polyurethane resin which can be deployed quickly enough over a wide range of temperature from very low to high and which can exhibit stable performance without danger of blocking is made of silicone modified thermoplastic polyurethane resin in which the content of siloxane is 5-40% by weight. An occupant can be protected by the air bag over a wide range of temperature such as from -40.degree. C. to +100.degree. C.
