Automobiles are being equipped with airbags that inflate on collision to protect the driver or passenger from injury. A car?s airbag is located on the steering wheel, this airbag is for the driver, and on the dashboard, this airbag is for the passenger. Automobile airbags are inflated by the electrical system and sensors in the car that triggers a chemical reaction to occur. When a car is involved in a car accident the airbag rapidly inflates and deflates to cushion the driver or passenger. In addition, for an airbag to successfully inflate, the propellant goes through a chemical reaction to produce the gas that inflates the airbag.

An airbag is successfully inflated when the automobile?s electrical system and sensor detect that the automobile has been involved in an accident. This whole process is part of a complex electrical system that a car is equipped with. The sensors consist of a tube containing a ball held in place by a spring. In a frontal impact, the ball is forced against the spring in proportion to the severity of the crash. Other systems use an accelerometer instead of crash sensors, frequently located within the steering column or in the airbag assembly itself.


anti-lock braking system (commonly known as ABS, from the German name "Antiblockiersystem" given to it by its inventors at Bosch) is a system on motor vehicles which prevents the wheels from locking while braking. The purpose of this is twofold: to allow the driver to maintain steering control under heavy braking and, in most situations, to shorten braking distances (by allowing the driver to hit the brake fully without the fear of skidding or loss of control).Anti-lock braking systems were first developed for aircraft

On high-traction surfaces such as bitumen, whether wet or dry, most ABS-equipped cars are able to attain braking distances better (i.e. shorter) than those that would be easily possible without the benefit of ABS. An alert skilled driver without ABS should be able, through the use of techniques like cadence braking or threshold braking, to match or improve on the performance of a typical driver with an ABS-equipped vehicle
