It’s only the interaction of airbags and belts that enables better protection against impact. So the Sprinter crewbus not only has full-size airbags [1], optional windowbags and thorax bags, but also three-point seat belts, head restraints, belt tensioners, belt force limiters and belt reminders [2].

Belt reminders give the driver or co-driver a visual and audible signal if they fail to put on their seat belts.

In a collision, belt tensioners instantly take all slack out of the belts and enhance passive safety in the event of an accident.

Windowbags and thorax bags [3] deploy on the impact side in severe side collisions. The windowbag serves to increase the degree of protection available for the head of the driver or co-driver. Housed in the seat backrests, thorax bags are designed to provide increased protection for the thorax of the seat occupant.
