Mercedes-Benz has released this image of a new safety system in action. The Beltbag is an inflatable seat-belt strap intended to reduce risk of injury to passengers in the rear in a head-on collision by reducing strain on the ribcage.

Should the crash sensors detect a severe frontal impact, the airbag control unit will trigger deployment and inflation of the Beltbag. A gas generator then inflates the multi-layered belt strap with Velcro seams to nearly three times its normal width. The resulting larger surface area is able to better distribute the force acting on the seat occupant, reducing the risk
of injury.

The Beltbag can be used in exactly the same way as a conventional seat belt. The belt strap’s design is different from that of the standard belt though, and received top marks in practical trials for being extremely comfortable to wear and for its extra-soft belt strap edge.
