ABSTRACT

The present topic is about safety airbags in cars. No safety device

has consumed more attention and resources than the airbag. It is known

with high confidence that when a crash occurs , the presence of

airbag reduces fatality risk to drivers.

Airbags are subject of serious government and industry

research. My seminar takes you to the history, development and working

aspects of airbag.
