Research Investigation Safety features in cars Air Bags Air bags are safety features installed in cars so that upon collision the driver limits the damage that is inflicted on him/her. There are several different types of air bags. These include‚ Supplementary Restraint System (SRS)‚ an Air Cushion Restraint System (ACRS) and the Supplemental Inflatable Restraint (SIR). Air bags are commonly known for their rapid inflation upon a collision. They can inflate and deflate within 0.05 seconds
