Head in the air

A helmet containing
an airbag
that inflates to
cover a motorcyclist's neck and
shoulders has
been invented by the
Ireland-based
Airbag Technology
Inc. The inside
of the helmet has a
head shield
linked to a sensor
that can detect
any sudden impact. In
a crash, the
unit releases a
cylinder of highpressure gas, which
inflates the
airbag. The helmet's
inventor says
that the device
should minimise
broken necks in
accidents by stopping sudden head
movements. The
airbag, which is
stored at the back
of the helmet, is
covered with
diniples; to ensure
the wearer is not
suffocated by it.
