In a way, my design works as much because the belt is comfortable for the user as it does because it is safer.
Nils BohlinI realized both the upper and lower body must be held securely in place with one strap across the chest and one across the hips. The belt also needed an immovable anchorage point for the buckle as far down beside the occupant's hip, so it could hold the body properly during a collision. It was just a matter of finding a solution that was simple, effective and could be put on conveniently with one hand.
