What is an Airbag:

• An airbag is an elastic bag or cushion like makeup which inflates and deflates quickly at some stage in certain types of car accidents.
• It is a safety device aimed at preventing or minimizing injury to passengers when such an accident occurs.
• Airbags have been efficient to put a stop to severe head and chest injuries in adults when automobile accidents have occurred.
• Airbags can be located in both the front and rear of vehicles.
  1. Frontal Airbags: The airbag component for the driver side is situated in the centre of the steering wheel, whereas the passenger side component (if equipped) can be found in the dashboard above the glove box.
  2. Side Airbags : There are three different types of side air bag systems currently available:
     1. Roof-mounted side airbags designed to protect the head and neck.
     2. Door-mounted side airbags designed to protect the chest.
     3. Seat-mounted airbags designed to protect the chest and head.

Product characteristics:

1. The airbags are made  in the following manner:-
   
2. The yarn / fabric are primarily nylon 66 or polyamide 66, lighter denier, lower dpf and silicone coated.
3. Approximately, 1.8 square meter of fabric is used per airbag module.
4. Nylon 6, 6 is used as a key raw material.

The Component of air bags:

• Air bag production involves three different separate assemblies that combine to form the finished end product, the air bag module.
• Air bag module assemblies are:

1. Propellant: It is consists of sodium azide combined jointly by means of an oxidizer, a stuff that facilitates the sodium azide to burn up when ignite.
   
   
2. Inflator assembly: The inflator machinery, such as the metal container, the filter assemblage—stainless steel wire net with ceramic substance in the interior—and initiator are received from outside dealer and examined. The machinery is after that brings together on an extremely automated manufacturing line.
   
   
3. Air bag: The woven nylon air bag fabric is purchased from external dealers and examined for any material flaw. The air bag fabric is afterward die cut to the appropriate form and sewn, internally and externally, to appropriately join the two sides. Once the air bag is stitched, it is inflated and checked for any seam defects.
   
   
4. Final assembly of air bag module: The air bag assemblage is then mounted to the tested inflator assembly. After that, the air bag is fold up, and the breakaway plastic horn and protection cover up is installed. Lastly, the completed element assemblage is examined and tested.
   
   
5. Other components: The left over parts of the air bag system—the collide sensors, the diagnostic monitor unit, the steering wheel linking coil, and the display lamp—are joint with the air bag component at some point in vehicle assembly. All the parts are joined and communicate throughout a wiring harness.
