A small
folded up
fabric bag in many
automobiles of today. Often in the
center of the
steering wheel, and on the
dashboard on the
passenger side. They use tiny
MEMS sensors to
detect an
accident, and then using
gas they
inflate in an
instant to help
absorb the
impact and
cushion the
passengers.
They have a nasty tendency to be harmful when little children are placed in the passenger seat, especially those in a car seat.
