Toyota has developed the world’s first SRS (Supplemental Restraint System) rear window curtain shield airbag to protect rear passengers’ heads in the event of a rear-end collision.

"The airbag deploys from the roof lining above the rear window in the form of a curtain-like barrier. Together with the headrests, the airbag minimizes impact to the head from a colliding vehicle or parts of the hit vehicle, thus helping to reduce the severity of injuries."

If you've been paying attention to Toyota news you'll also be aware of other available collision safety technologies - resulting in such achievements as the swift market introduction of SRS curtain shield and knee airbags - to enable its vehicles to better respond to a greater range of accidents.

Just one more way that Toyota = safety :)
