Toyota iQ rear airbag

Toyota has developed a rear window curtain shield airbag which will make its debut on its new iQ city car.

The new airbag system deploys from the roof lining above the rear window in the form of a curtain-like barrier to minimise injury in the event of a rear-end collision.

The rear curtain airbag will come as standard on the iQ when it goes on sale in the UK in January.
