Seat Belt Thoughts

That's what's in my Jeep. I like them, retractors lock up fine on hard braking but let you move around wheeling unless it really gets bumpy. Read the instructions as they are specific about angles behind the shoulder slots.

 

highly recommend the 3 point belt.i have mine in the '69 cj5 with upper point attached to a lug on roll bar .works great and much more secure feeling.mike

 

Located a threaded weld through bung just for seat belt mount. Two holes in the roll bar and weld both ends. Looks factory.

 

Guys, he's putting this in a Willys wagon, no roll bar for the upper mount.

 

Sorry. Speed reader and I read it twice. I blame blue tunnel vision.SeatBeltsPlus has a weld/rivet in plate. I believe it is metric and uses a shoulder bolt to mount the belt. I used some rubber washer
under the the belt to allow movement but not rattle. This is for a 'B' pillar installation with 3-point harness.

 

There is lots of info out there on the correct installation of this type of restraint system. It concerns the pressure applied to the spine should you be involved in an accident. Most are installed incorrectly. Floor mount is not recommended but use a bar behind the seats at a specific height.

 

It's not a great idea. Ideally the rear harness is horizontal. From Corbeau themselves, 45 degrees from horizontal max:



You really need a higher anchor point. A roll bar, a bar spanning behind the seats, or a threaded bung on a piece of plate welded to the B-pillar.

 

That is showing for a low back style seat. Has me thinking that if the restraint holes are built in to the seat then the belt is already in a fixed position, would it
really matter what the belt angle is? I researched thiis before and never came up with a good answer.
I have a good 2000 tabs open at any given time but you are quick!

 

If you can't weld them in, use good rivnuts and tool. Your life may depend on it.

 

That is what I used in the stakebed.

 

In that case you are relying on the strength of your seat latches to not break and hinge forward in a collision. If the do, the seat belt will be crushing your spine.

Some seats are designed for those loads like the Superduty seats below, but I wouldn't trust seats that aren't.



James might be better looking in wrecking yards for seats with integrated belts and figuring how to really securely mount them to the floor.

 

2nd gen 98.5 and up extra cabs dodge trucks had seats with integrated belts. might be easier to locate then super duty seats. I only say that since i see way more 2nd gen dodge trucks in the pull aparts then fords

 

I do agree that rivnuts spread out as far as you can reasonably get them to lessen the loads and a large plate would probably be acceptable.

Even a non severe crash can be 30Gs. If your upper body weighs 100 lbs, then your looking at upwards of 3000lbs tension on the upper anchor in a collision.

 

Maybe. But I'm not sure if the seat is part of the real picture other than to keep the belts in the proper position over the shoulders to the quick release lap belt.
In other words the belts hold the seat. Then again...if the belt went straight to the floor it could not keep the seat in position. Ok, the angle of the rear strap has
to support you and the seat. I looked in to this before but just read the words and not how it applies. That's why I went to a 3-point system. I do like the wide
racing lap belts for off road though.

 

Thinking of a square cut hole to slip the plate up through and bolt/rivet in . Patch/weld hole and done. This would give be the most structural way of mounting. Then you can go back to your snow err, powerlock.

 

Big seats and narrow cab.
