I was never a fan of harnesses. Never found them practical for a DD as you can't lean forward at all.
The hell do you do when you drive? They arent practical for most people bc they think a car is a dinner table, and eat and drive, look at little kids, they are strapped in place pretty tight in a CARSEAT! if people used cars for what they are for (drive and get to places) harnesses are the best for a vehicle.

But please tell me what your doing when you drive. As im curious why you would need gobs of slack in a seatbelt or as to why they arent practical.

So you've never leaned over to grab anything ever since you've been driving? Never stretched out on a long ass drive across the states? Never lean forward a good bit to get a better view of some blind spots at intersections? Never leaned over to look out the rear window to back up? For a DD they aren't very practical, but that's just my opinion.

They're not practical because harnesses actually make it worse unless you use a harness bar. The harnesses aren't bad its the harness bar in the rear that kills it. I love seeing dummies like "look how safe I am with my harnesses" yet have no bar. Yes it makes a huge difference. Once you snap a collar bone in even a low speed collision you'll realize the importance of them.

Btw, not implying this is OP as I can't tell if he's running one or not.

Again, harnesses have slack! :thumbup:

Harness bar is NOT needed for harnesses, harness bar just makes it easier to use harnesses, and makes the back seat even more dangerous for passengers.

harnesses come through buckets seats at the same point and lay over the driver in the same manner when using a harness bar or bolted into the frame. A factory seatbelt lays across the chest and collar bone as well. You make no sense to me ;)

you can have some slack to the belt, just like a standard seatbelt gives slack until a certain point in a quick motion. I can lean forward, but i could never headbutt my steering wheel.
This is great. Haha.

Build is looking good, Alex!

A factory seat belt also has a mount higher up. Placing the stress more evenly and higher. When you bolt them to the floor without a bar it pulls them down harder. I guess race cars that use them make no sense either. They don't make them just because they look cool. Sorry you don't understand the concept, but doesn't make it wrong.

I was unaware of this until I started building my miata. This isn't my theory on it. Its facts, google it.

How easier? Most of the time the harness isn't even mounted to the bar.

Seems like someone might need to check their blood pressure real quick. Calm down their Sally.

I think most people do it for looks tbo. If you stay firmly planted in spot while you drive, more power to you I guess.

Bolting them in the floor doesn't pull them down. There is nothing pulling on them! My info is based off of facts and real life personal experience. I don't get pulled anywhere from a harness, its not designed to pull! It's designed to hold. If you think o have harnesses for a look, you're hugely mistaken.

Holding, pulling, in the event of a collision there is force or are you going to argue that also? You said it yourself you're being held. Do you want to be held down or back? Personally I like my spine.

Also, I never said you had harnesses for looks. I asked if you thought harness bars were made for looks.

Just because you've done something before doesn't mean it was right.

Right on point Rabbit!

Theres reasons that there are certs for drag cars and such and u will not pass tech without a bar to attach harnesses to at shoulder height.

That article was great and is perfectly written.

Thank you and child, I've ready many of your other post before. You are very knowledgeable. I don't want to discredit anything you may have said. Sorry if I came off as an ass. When I was building my miata this and roll bars were a huge discussion. As you could imagine they're a huge deal in a car with no roof.

i dont believe harness bars are made for looks, but i do believe they are necessary in specific applications, not all applications. Yes there is force, and the driver is being held. Both installations of a harness (the proper rear chassis points and a b-pillar bar) hold the driver in the bucket seat. The eyelets in the bucket seat allow the harness to hold the driver in the same manner. Force isn't applied to the driver differently after the harness has passed through those eyelets. If there was no eyelet, just an open should like a normal seat, then the mounting location would make a difference. The reasoning for bolting the harness to the proper chassis points is for strength. A harness bar does the same thing, except it's even stronger because it adds a solid bar through the virtual center point of the car which increases it's strength. it's basically a small piece of roll cage. Everything you're mentioning is solid for a miata...it's a roadster and has totally different dimensions from the OP's car.

oh, and you don't come off as an ass or anything, I think it's good information and insight for the OP and others reading this thread

Again, the tech requirements are set for a highER level of safety. Takata harnesses are FIA approved with instructions on installation and even make a chassis bolt in version of the harness as well as a harness bar version.
 

crash!

Woooooweeee!! What did I miss?!

No nothing for the coupe for Christmas besides the Takata. Everything else I want is too expensive and I wouldn't expect anyone to get it for me. So I get paid today and I'm ordering my charge piping for the turbo kit.

For those who are wondering, I have my harness bolted to the points on the floor where the rear seatbelt is bolted down. I have some slack to my harness (enough to check my blind spots and such) but not a terrible amount. I like to feel secure in my seat.
As far as the harness bar goes, I've thought about running one. Although one, I like to have a third passenger in my car, and two, I'm hesistant about running bars in my interior without going full on with a cage. Correct me if I'm wrong, but I just feel that's not safe. I hate kids who put cages in their car and say "look Ma! It's safe!" when your skull will be bouncing off it like a pinball machine in a wreck. I'm wondering if the harness bar will have the same risk (probably not as much). And yes, the harnesses I have are FIA approved.

CHILD, how did you run yours? From what I've read/heard, from where I have mine mounted is fine. And my car won't be seeing the track for quite some time.
