Rolls-Royce Motor Cars' innovative passenger airbag concept has won the Society
of Plastics' Engineers' (SPE) Grand Innovation Award.
The engineers working on the Rolls-Royce Project were also presented with the
SPE's Automotive Division Grand Award. This award is granted annually in
recognition of innovative developments in the processing and use of plastics in
the automobile category. The Grand Innovation award is the most prestigious of
all the SPE's awards with the winners of each specific category going forward
for an overall 'top' award.
The Engineers impressed the judges with the
pioneering design of passenger airbag, which deploys without the need for the
leather trim to tear or the surrounding parts to separate, setting new standards
in technological design.
The Phantom's airbag specification demanding
that there was no separate cover, no weakening of the leather trim and no egress
through leather stitching was a major challenge for the development engineers
and interior specialists.
The airbag is folded in such a way that allows
it to follow a defined route through a gap between the leather covered dashboard
top and the adjacent magnesium alloy instrument panel support. In its initial
milliseconds of expansion the airbag pushes the dashboard top upwards, creating
a gap through which the airbag can deploy.
Through the innovative use of
plastic materials the engineers were able to solve this problem while still
retaining the highest standards of quality and design expected of
Rolls-Royce Motor Cars.
