Definitions

• the invention relates to a fabric which is made from a synthetic fibre, preferably polyamide, and which constitutes a cloth possessing high tensile and tear strengths.
• the cloth is intended to be used as the material of impact-protective, inflatable air bags utilised in motor vehicles.
• a gas generator is used of a kind comprising a propellant which upon ignition rapidly develops a hot, air-bag inflating gas.
• the substance generally used is sodium azide (NaN 3 ) , which forms nitrogen gas (N 2 ) .
• the invention provides a fabric by means of which all problems referred to above are solved.
• the characteristic feature of the invention is that the fabric face forming the inner face of the air bag has a coating applied thereon.
• the coating consists of one or several layers of polymer with admixture thereto of a pigment having heat-reflecting properties.
• a suitable coating for this purpose has been found to be a silicone elastomer with admixture thereto of an aluminium paste or aluminium pigments .
• Measurements were carried out on a fabric sample mounted on a spacer ring, with the aluminium-coated surface facing downwards, towards a heated measurement plate and spaced 15 mm from the plate.
• the environmental climate condi- tions were as follows: temperature 20°, relative humidity 65%, air velocity 0.5 m/s.
• the fabric may be thin, yet strong at the same time, and therefore requires only a small space inside the module.
• a fabric with said coating applied thereon is able to resist also high-temperature gases. Consequently, a propellant may be used that develops a higher-temperature gas than does sodium azide but that is non-toxic, and this without involving risks for fusion damages to the fabric .
• the thermal reflection increases the pressure inside the bag.
• the power of the gas generator may be reduced and a smaller amount of propellant need be used.
• the air bag is exposed to less stress while at the same time cost savings are made.
