Head Protection System (ITS)

The ITS consists of a hermetically sealed rubber tube that is encapsulated by a cross woven tubular nylon material. Each ITS is mounted from the "A" pillars to the roof panel just behind the "B" pillars by a nylon strap and mounting bolt.

When deployed, the inflation charge causes the diameter of the ITS to expand and its length to shorten. As the length shortens, it is forced out of its stowed position of the roof lining and it extends over the glass to protect the driver or passenger's head.

The ITS remains inflated for approximately seven to eight seconds to extend the protection time should the vehicle encounter additional side impacts during the crash.
