A collar around his neck blows up into a protective helmet during an accident. The new airbag for bikers shows up for the first time at the Technical Fair in the next week.
We saw a great need for a bicycle helmet that is not ugly and not ruin your hairstyle, "says industrial designer Teresa Alstin.
She and colleague Anna Hauptmann began developing his helmet during his
training six years ago and together they run the company chiefs in
Malmo.
On Tuesday of next week for the first time show the new helmet in
Engineering Fair where they are also one of the nominees for the high
price Inventors Create.
The helmet is actually a collar with a zipper that the cyclist has
around his neck. The collar is a folded air bag that deploys when the
accident occurs. For it to come up properly on the head extends itself
gradually. At first stabilize the neck. Then blow it up along the back
of the head and finally over the crown and forehead.
Much of the development work has been devoted to develop the algorithms
that control when the air bag will be redeemed. The firm's 12 employees
are also most engineers and mathematicians.
Just like airbags in cars using the Chieftains a combination of
accelerometers and gyroscopes that sense the rider's movements. They
have been programmed so that they can distinguish a cyclist's normal
movements of the abnormal movements that characterize an accident.
- It has been the real nut to crack. We have compiled data from hundreds
of accidents and staged all kinds of accidents that occur, both using
dummies and stunt performers, "says Terese Alstin.
To inflate the crash helmet, a small gas generator containing helium, this sits in a container on the back.
It is triggered at a tenth of a second and after a crash helmet is exhausted.
