What the E means is that your safety-belt, like any other safety-belt in any other car sold in Europe, meets the high standard of safety set forth by UNECE through an international agreement. In fact, you’re going to find that E on more than just your seatbelt. It’s on your windshield, and your tires, as well as places you don’t even see in your car. It’s on your child’s car seat and on the latch that the car seat connects too. For that matter, it’s outside your car too. If you look on your bike or motorcycle helmet, you’ll likely see it there as well.
