The "Hit Air" airbag vest incorporates an air cushion system. In the event of an accident and a rider is thrown from the horse, the air cushion instantly inflates (within 0.25 second) to protect the rider's body.
Activation is simple and automatic. A coiled wire is attached to both the horse and the vest. Once the rider and the horse are separated, the coiled wire pulls a "key" out of a gas release system and inert gas inflates the air cushion.
The inflated vest provides the necessary impact protection. After a few seconds the gas is automatically released through the gas release valve.
