Safety Devices
1) Seat Belts: Most newer vehicle has three (3) point system; shoulder / lap and pretensioner (pyrotechnics to trigger / spring loaded).
2) Airbags: Most airbag systems are made up of three basic components. They are as follows:
The bag: is constructed of a woven material similar to nylon, which is folded like a parachute. They are coated with talc like powder that lubricates the air bag material for storage. After deployment, this powdery dust may contain residue from the chemical reaction, which may cause minor irritation.
The inflation system: is similar to a solid rocket booster. This solid material ignites which burns extremely hot and rapidly to create gas. This action inflates the nitrogen gas (pulsed) via the chemical reaction of sodium azide (Na N3) and potassium nitrate (KNO3), in some older vehicles.
In advanced systems vehicle manufacturers (OEM's) are using special sensors to differentiate occupants size and/or weight. This in turn can vary the output of the airbag(s), which in fact makes the system safer. Many OEM's use a propriety chemical compound, which they claim to be less
toxic, then NaN3 for the inflation system. The airbag itself may have multi-stage compartments, which infact slows the forward velocity (up to 200 mph / totally time is 20-30 milliseconds; first version) of the bag and has a maximum pressure of 5 psi fully inflated. Some newer vehicles, are being equipped with side / curtain, knee, belt(s), seat / door mounted airbags as well as the required frontal ones. Most side airbags have separate highly compressed air tanks (approx. 3.5K), which make the system potentially dangerous for first responders, if they do not have the proper information.
Some newer vehicles have next generation headrests. In these systems, the headrest(s) actually moments2 in a specific direction for the impending impact, to minimize the person head motion, in order to lower the injury level, e.g. whiplash, etc.
Most parts of a vehicle is either a friend or foe. When a vehicle is impacted, whether from another vehicle or an object, there are impact force(s) that occur outside and inside of the vehicle, from at least one direction, that can cause injuries, whether from the vehicles own equipment and/or devices that may react, e.g. seat belts locking- up / tighten, airbag deployment, dashboard components, etc. As the reactions occur from the impact, the occupants will move in the same and/or opposite direction of travel and/or impact and speed. Impact forces (energy) and/or airbag(s) striking an occupant that is wearing eyeglasses, can cause additional injuries, depending on the type of material the lenses. High risk eyewear can be potential dangerous when impacted by impact forces of a vehicle, such as a steering wheel, dashboard, airbag(s).
Conclusion
Drivers can reduce the possibility of airbag injury (ies) by properly adjust their seat belts and sitting at least 10 inches from the steering wheel, measured from the center of the steering wheel to their chest. However, if the driver cannot operate the vehicle in a safe and comfortable manner, due to their physical dimensions, pedal extenders should be installed. All occupants can reduce possible eye(s) injuries due to impacting should consider wearing safer eyewear lens material, if available, such as Polycarboate, Trivex, and CR-39; See Figure 1.

Each year there are approximate 10 - 21 million motor vehicle accidents (1980 - 2010) that occur. It is the engineer that has an engineering and science background along with other education, that can investigate these accidents.
