(2) In approximately 20 milliseconds after the collision, the
air bag folded in the pad cover will begin to inflate, the
pad cover will break at its crease, and the air bag will
expand outward.
(3) In approximately 35 milliseconds after the collision, the
inflated air bag will touch the chest of the driver.
(4) In approximately 40 milliseconds after the collision, the
air bag will be fully inflated.
(5) In approximately 55 milliseconds after the collision, the
pressure of the driver against the air bag causes the gas
to escape through the two exhaust holes on the rear of
the module, and the deflation helps lessen the impact im-
posed on the driver.
(6) In approximately 105 milliseconds after the collision, the
air bag that has absorbed the impact will rapidly deflate,
providing visibility for the driver.
