AIRBAG FOR A RESTRAINING SYSTEM IN VEHICLES AND FABRIC FOR MANUFACTURING THE SAME

An airbag for restraining systems in vehicles consists of several pieces of fabric sewn together having different gas permeabilities. All pieces of fabric that constitute the airbag are made however of the same type of fabric determined by yarn density and filament yarn. Up to an overpressure of about 10 kPa, the gas permeability curve of the whole airbag rises as a function of the inner overpressure up to a value between about 0.4 and about 1.0 m3/s., then continues to rise when the overpressure values augment from about 10 kPa to about 20 kPa, reaches a maximum then falls once again and continues to fall when the overpressure value lies between about 20 kPa up to at least about 40 kPa. This course of the gas permeability curve means that the hardness of the airbag is automatically regulated, so that the reduced hardness reduces the risk of injury in the initial phase of pressure build-up, whereas in the case of an intense impact the increased hardness of the airbag prevents it from being ...
