Rear Seat Belts

[RNajarian]

I wanted to pick the brains of the more experienced buggy owners here.

My 4 seat 2006 ACG H3 (based on a CC President) has seat belts only in the front. I’ve purchased a pair of seat belts for the rear seat and want to install them to ensure the safety of my passengers.

Experience from wrenching cars for many years tells me the seat belts must be attached to a hard point on the frame.

However, the front seat belts, which were (assumedly) installed by the manufacturer were simply attached to the fiberglass shell, NOT attached to a frame hard point.

When installing the rear seatbelts, is it acceptable/safe to merely bolt the seat belt receptacles to the body shell and NOT attach it to a hard point?

I’m worried that the seat belts only attached to the cart’s fiberglass shell may damage/crack the body/shell.

Would placing two large washers on either side make a difference?

I’ve included a few photos.

One is of my front seat seat belts.

The second is of my back seat currently

And the third is a photo I got off the web of someone else’s cart with rear seat belts installed..

Thanks

Something to remember is that it's a golf cart, and the seatbelt is not likely to save you regardless of where/how its attached to the cart. It's kind of a visual appeal I guess.
The kits I've installed come with hardware so cheap I think it would break if you looked at it the wrong way. Maybe it will slow the momentum of a flying person if an accident occurs, but I wouldn't count on them to keep the person secured in the cart, in the case of an accident at speed.

Really a lap belt is pretty much useless as a safety device, since most injuries in an accident come from the head or upper body colliding with an object (such as the steering wheel, window glass, or roof pillar). There is also ZERO protection from whiplash, as the grand majority of carts have only half back seats, and no head rest/restraint.
If you get in a wreck with a golf cart, the fiberglass body is probably the first thing that will make impact, and the last thing you really need to worry about.

Naturally in the event of a crash the cart is disposable. However, if it is only attached to the fiberglass shell will that be sufficient to restrain the passenger from being ejected, or should it be affixed to a hard point?

Are they (rear seats) attached to hard points when they come from the manufacturer?
