Honda Develops World's First Driver-side i-SRS Airbag System with Continuously Staged Inflation

TOKYO, Japan, September 18, 2008 - Honda Motor Co., Ltd. announced that it has
developed the world's first driver-side i-SRS airbag system that continuously
stages the volume of airbag-inflating gas, thereby combining enhanced occupant
protection with reduced occupant impact. Honda plans to implement the new
continuously staged inflation i-SRS airbag system on the driver's side of the
Life minicar to be released in Japan in November 2008.

A Honda innovation, the new i-SRS airbag system features a spiral-shaped seam
structure and gas release control valve to control airbag deployment and
pressure for faster deployment, reduced occupant impact and a longer period of
inflation and occupant protection. As a result, the new system accommodates a
broad range of occupant positions and potential collision situations.
Honda first began fundamental airbag research in 1971, and in 1987 became the
first to introduce a driver-side SRS airbag system in an automobile manufactured
in Japan. In 1990, Honda was the first automaker to introduce a passenger-side
SRS airbag system in a vehicle manufactured in Japan. In 1998, Honda introduced
the world's first inflator with a two-stage deployment system, as well as an i-side
airbag system with an occupant position detection sensor. Continuing its
tradition of innovation, Honda continues to be a world leader in researching,
developing and introducing new automobile safety technologies.
• Three features of deployment mechanism
Since the system can pressurize the airbag faster, it can begin to protect the
driver sooner. The spiral structure of the airbag allows the protective surface
to be formed at a lower overall airbag volume, thereby providing protection
faster than was previously possible.
Longer period of inflation and protection
The new system maintains a constant pressure within the airbag, thereby allowing
for a longer period of inflation and protection. The seams within the spiral
structure of the airbag are designed to expand from the inside of the spiral
outward, thereby maintaining a constant pressure while continuously staging
airbag inflation. From the moment of deployment until the preset moment of
deflation, the airbag is designed not to release gas, thereby maintaining a
constant pressure and occupant protection.
By minimizing the degree of protrusion into occupant space and lowering the gas
output of the inflator, the new system reduces impact on the driver. Unique
spiral seams within the airbag help reduce the degree of airbag protrusion and
impact on driver. From the moment of deployment until the preset moment of
deflation, the gas control valve prevents the release of gas. This efficient use
of gas allows for reduced inflator output and reduced occupant impact.
