Question about a 4 point belt.

I was looking around and reading about the safety of a 4 point harness and I came accross some information that said that they might be dangerous if not attached to a proper place. I was wondering if this setup would be safe: http://images.andale.com/f2/123/119/...ED_BKRBNLc.jpg

I think the main concern with these belts, is that in a crash the driver tends to slide through the bottom. A 5 point system, with the "crotch" belt will hold you in place. Probably wouldn't help the old family jewels much, but at least you would be around to feel the pain.

4 point harness

The main thing when mounting a 4 point is the shoulder harness. Dont mount it to the floor. When you crash and its mounted to the floor the harness will pivot from that piont and you start to compress your spine leading to a ruptured disk or worst. You should always use a bar that goes behind your seat like a roll cage. Unless you want the seat for looks and just dont hook up the shoulder harness. Just be safe.

Poncho is correct to some extent about a 4 point. The condition is called submarining. The 5 point takes care of that but in the case that you do load it it works the "boys" pretty good.

4 points are fine as long as cushion angles are no less than 20 degrees to reduce the sub but the lap belts need to be fairly snug at all times to hold the hips/pelvis from rotating. Whether using a 5 or a 4 the snugging of the belts is important as you don't want to introduce a "Shock load" to the anchors as it greatly reduces their effectiveness.

Also Nova is correct that unless you have a dual recliner heavy framed seat that is specifically meant to carry loads and anchor points identified by manufacturer. You should never go directly through the back to the floor or mount harnesses to a seat back as you will accordion the back when loading the straps.

The proper install is a structural cross bar from a roll cage (you can mount to the floor after passing over the bar mounted at the shoulder level or to the bar itself. To the bar is the safest as it is the shortest tether) or a hidden structural bar under the package tray with a tether strap (but that removes any rear seat use ever.

I am not a big fan of the use of the partial set up and the rest for show, if you use only the lap you are not going to be in the correct configuration for the buckle to the abdomen. So really think about it before you go that route.
