4-Point Safety Belts

2-Point: First we had shoulder belts: They were no good if the car rolled over or was hit from the side.

3-Point: Now we use shoulder and lap belts. They keep you in your seat, but don't stop your upper body from lashing about during an impact.

Next we will have 4-point safety belts. I saw this setup today on a BMW scooter, but the same system could be used in a car: By your left shoulder you pull down a conventional 3-point safety belt. Then, by your right shoulder, you pull down a shoulder belt and latch it near your left hip.
