The "airbag" was developed by American industrial engineer John W. Hetrick, who patented and built the prototype on his galley table in 1952. The blueprint resulted in a gas-filled envelope that can be automatically spread out to cushion passenger bump during a van crash. Breed Association took Hetrick's aboriginal duty and enhanced the constitution by adding disparate active trigger sensors. This facade to the airbag's internal operation in conjunction with distinctive "Chock-full Three" companies in the overdue 60's, with a headmost Industry roll-out in GM's Buick Electra edge in 1974.
Front Airbags
Airbags are operated on the goal of three components: An airbag module; one or extra crash sensors, including an accelerometer; and a managing diagnostic unit. The front airbag is contained in the steering turn, with a secondary sprint panel bag on the passenger side above the glove box.
Side Airbags
Side airbags are located in the headliner on either side of the passenger compartment. The intent of these devices is to mitigate the impact of a sidewards movement in a crash.
Knee Airbags
Knee airbags can be carried under the passenger glove box, and also under the back of the front seats. The intent is to limit knee impact in the event of an accident.
Rear Curtain Airbags
The variance is based on several factors, including angle of impact, its characteristics (meaning a direct, or deflected secondary hit), transient velocity, or other pressure metrics, as established by the on-board airbag system instrumentation. While these devices do reduce crash fatalities, there are some potential downside impacts in the case of slower speed incidents. These can include abrasions of the face and body, bruising, or in certain circumstances broken bones.
Rear curtain airbags are designed to drop down behind the rear passenger compartment, to primarily cushion the impact of a rear-end collision.
