It seems that just a few years ago air bags in cars were exotic. Today their numbers in some models are up to 10. At first glance, it’s a simple bag made of a smooth, elastic synthetic material. But the fabric of an airbag needs to be very thin and strong, during the accident even the smallest stitches should not not be in the contact area with driver’s face and body. The cushion should’nt also become a trampoline, it must be able to ease the gas pressure on time. In fact, many manufacturers have ceased to sew pillows using the fabric that breaks letting the air out. When packing the airbag they put talc powder to prolong the cushion’s life.
