Head Airbag Assembly (Its)

The ITS is designed to protect the head in the event of a side impact. The assembly consists of a hermetically sealed rubber tube that is encased by a cross woven tubular nylon material, a gas generator and ignition pill.

The ITS is mounted from the "A" pillar, at the front, to the roof panel slightly behind the "B" pillar. The ignitor is mounted to the "A" pillar and is connected to the ITS through a reinforced sealed tube. The ITS is stored behind the roof panel trim over the front doors.

When triggered, the inflation charge causes the diameter of the tube to expand and its length to shorten. As the tube expands, it is forced out of the stored position and it drops over the side door glass to protect the occupants head against impact. The ITS remains fully inflated for several seconds after it is triggered due to the sealed expansion tube. This allows the ITS to continue to provide protection in the event of a secondary impact. The tube will deflate after the gas cools.

The expandable tube of the ITS is the same for all models. However the securing strap at the "B" pillar end is a different length for the different models. For this reason, the ITS is part number specific for each model and cannot be interchanged.
