INTRODUCTION
Seat belts have been proven to be effective in saving lives and preventing or lessening injuries in automobile accidents.
The key to their success is that occupants must use these safety devices. Because seat belts require active use by the wearer,
Inventors developed passive restraints to ensure driver and passenger safety.
The first passive restraints were modifications of seat belts themselves; the belts built into tracks in the doors to wrap around the driver or passenger when the seat was occupied.
Concurrently, the airbag was devised as a secondary form of passive restraint during impact
INVENTION
An American inventor, John Wenrick,a retired industrial engineer,designed the original safety cushion for automotive use in 1952
Dr. David S. Breed, invented and developed A key component for automotive use: the ball-in-tube inertial sensor for crash detection.
Breed Corporation then marketed this innovation first in 1967 to Chrysler.
A similar "Auto-Ceptor" crash-restraint, developed by Eaton, Yale & Towne Inc. for Ford was soon offered as an automatic safety system in the USA,while the Italian Eaton-Livia company offered a variant with localized air cushions.
TERMINOLOGY
Various manufacturers have used different terms for airbags.
General Motors‘ first bags, in the 1974s, were marketed as Air Cushion Restraint System (ACRS).
Common terms in North America include
Supplemental Restraint System (SRS) and Supplemental Inflatable Restraint (SIR); these terms reflect the airbag system's nominal
role as a supplement to active restraints, i.e., seat belts used in Automobiles
Airbags As a Supplemental Restraint System(SRS)
The auto industry and research and regulatory communities have moved away from their initial view of the airbag as a seat belt replacement, and the bags are now nominally designated as
Supplemental Restraint System (SRS) or
Supplemental Inflatable Restraints
Variable force deployment front airbags were developed to help minimize injury from the airbag itself.
