So I'm not planning to race the car I'm working on, but was thinking about the seatbelts. Would it make any sense to put 5-pt belts in it to increase safety? Would it help to make up for lack of air bags? Does it even make sense without a roll cage?

I can see that. The different modulus of elasticity would let one shoulder travel further forward, making the body bend slightly around the lap belt, thus reducing the submarine effect. Interesting. Or you could accomplish the same thing by leaving the inside shoulder belt on your standard four-point harness slightly loose. Or upgrade to a five-point harness.
But this question wasn't about the different technologies used in four-point harnesses, it's the about the comparative safety of a standard three-point retractable harness compared to a four or five point. It was said that the three point harness is safer and the four-point harness is unsafe. I doubt both of those points in all cases, but especially in a side collision, and would love to see something empirical, either way. |
