Ford introduced rear-inflatable seat belts in the 2011 Explorer SUV, which in case of any accident are designed to help reduce head, neck and chest injuries for rear-seat passengers, often children and older passengers who can be more vulnerable to such injuries. Now, they’re also available in Fusion 2014. Still, it seems that many are skeptical as to its actual usefulness, and argue that it may hamper the safety of child seats that were not designed to work in conjunction with the inflatable belts. The only other manufacturer that offers a similar setup is Mercedes-Benz, which sells the all-new S-Class with rear inflatable belts too, though here the problem of mounting child seats never came up.
