Helmet high-tech can prevent athletes are quadriplegic

The technology has brought comfort to the helmets of cyclists. Now an innovation also brings an additional item of security, as has happened recently with the traditional safety helmets.
Protection for the column
Engineers University of British Columbia, Canada, invented a new helmet that prevents the practitioners of moutain biking, hockey and several other sports injuries in the spine.
In the case of a fall leading to a direct impact of the head against the ground or against an obstacle, the new helmet reduces the impact on the neck and spine in up to 56 percent, a gain that may represent the difference between the athlete to stand if and walking out or staying tetraplégico.
Helmet with double hulls
The gain was achieved by building up a helmet that has an internal mobile hull that guide the head slightly in the case of an impact, taking the tension that would be directed entirely by cervical spine. There is a reduction from 27 to 56% in strength and between 19 and 72% in torque, depending on the angle of impact.
“The current helmets were not designed to protect the neck and cervical region of the spine, which is precisely the most vulnerable,” says engineer Peter Cripton. According to data of Dr. Cripton, 10% of cases of damage to the backbone happen when people are using helmets.
The mechanism is triggered only when the impact occurs above a certain speed and under a certain angle, so that falls lower trigger the direcionador unnecessarily.
Baptism of Pro-Neck-Tor, the equipment has already been patented and is now in the process of negotiations with industry to arrive at market.
