Hi All,
For quite some time I have considered installing 3-point seat belts but have always come to a point of wondering their value and then put it off. I understand and share the desire for survival in an accident while in my Healey and always ware my lap belts purchased and installed when buying the car in 1964. However, when considering the purpose and function of shoulder belts, am I wrong in my understanding that head rests are a critically necessary requirement in their safety design and operation and without headrests, they are not safe?
Danne brings up a good point when presenting the potential for back compression if the retractor is mounted and anchored on the floor. However, since I am not a vehicle crash safety expert, I wonder if that is only one of the negatives resulting from that mounting location. I would also expect the shoulder belt to restrict movement and the seat and individual would pivot forward directly into the steering column. However, mounting the shoulder belt on the rear wheel arch, as provided by Healey, would help keep the body from moving forward in an accident but, without headrests, is susceptible to whiplash.
The Big Healey is far from the safest of vehicles to be in during an accident and I have never been able to reconcile the real benefits from rhetoric. I feel there must be benefits and would appreciate learning.
